[0003] This application claims the benefits of U.S. Provisional Application No. 63 / 027,113, filed May 19, 2020, and U.S. Provisional Application No. 63 / 085,672, filed September 30, 2020. The entire contents of these applications are incorporated herein by reference for all purposes. Technical Field

[0004] This invention belongs to the field of pyrimidine-based compounds for treating conditions involving abnormal cell proliferation, including but not limited to the treatment of cancer and tumors. Background Technology

[0005] In normal tissues, cell proliferation is typically limited to replenishing the cells needed by the tissue. Once cells have terminally differentiated, they acquire specialized functions and cease dividing. Most tissues are composed of non-dividing cells. Therefore, normal cell proliferation is strictly controlled to ensure that only necessary cells divide. A careful balance also exists between cell division and programmed cell death (apoptosis).

[0006] Cell division—sometimes called the cell cycle—has four phases: G1 phase (synthesis of various enzymes required for DNA replication), S phase (DNA replication produces two identical sets of chromosomes), G2 phase (synthesis of important proteins, including microtubules), and M phase (nuclear division, cytoplasmic division, and formation of a new cell membrane). Cell division also involves a complex network of cell signaling systems that allow cells to interpret information from a multitude of extracellular signals, including those from receptor proteins, inflammatory factors, and pro- and anti-apoptotic signals. Dysfunctional signals include those from gene mutations, infection, exposure to environmental factors including toxins, systemic stress, autoimmune diseases, and inflammation.

[0007] When the cell proliferation process becomes disordered, a range of conditions can occur, including benign growth, tumors, tumorigenesis, carcinogenesis, autoimmune diseases, inflammatory diseases, graft-versus-host rejection, and fibrosis.

[0008] Many broad-spectrum antitumor agents have been developed. Cytoskeletal drugs, such as paclitaxel, target microtubules to arrest mitotic cell division and are used to treat a variety of cancers, including ovarian, breast, lung, pancreatic, and testicular tumors (see, for example, Jordan, Wilson, Nature Reviews Cancer (2004) 4:253-265). Organometallic drugs, such as cisplatin, have been used to treat lymphomas, sarcomas, germ cell tumors, and some cancers, including bladder, small cell lung, and ovarian cancer. Cisplatin has the ability to bind nitrogenous bases and induce extensive DNA cross-linking that ultimately leads to apoptosis (see, for example, Siddick, Oncogene (2003) 22:7265-7279). Intercalating agents and alkylating agents have also been widely used clinically to treat a variety of tumors; however, the overall toxicity associated with these drugs is a critical concern for patients requiring long-term treatment.

[0009] Palbociclib (PD-033299; Ibrance), marketed by Pfizer, is used in combination with letrozole for the treatment of estrogen-positive, HER2-negative breast cancer. This compound inhibits CDK4 and CDK6. The structure of palbociclib is as follows:

In combination with osimertinib, one trial involved the use of osimertinib in patients with estrogen receptor-positive, HER2-negative (ER+, HER2-) breast cancer (NCT02983071). It is used in combination for the treatment of EGFRm non-small cell lung cancer. Lerociclib has the following structure:

[0016]

[0017] Trilacinib is a selective CDK4 / 6 inhibitor under clinical development by G1 Therapeutics as a first-in-class myeloprotective therapy designed to improve outcomes in chemotherapy-receiving patients by protecting hematopoietic stem cell and progenitor cell (HSPC) and immune system function. Trilacinib is a short-acting, intravenously administered CDK4 / 6 inhibitor administered before chemotherapy and is currently being evaluated in four randomized phase 2 clinical trials, including the first-line SCLC trial (NCT02499770) in combination with etoposide and carboplatin chemotherapy; and in combination with the same chemotherapy regimen and checkpoint inhibitor. (Azepam) in combination with first-line SCLC trials. Trilacizumab has the following structure:

[0024] Although research has been conducted in the field of cell cycle inhibitory compounds to treat abnormal cell proliferation in hosts (e.g., humans), given the severity of these diseases, there is still a need to find new compounds that can meet this medical need.

[0025] Therefore, one object of the present invention is to provide novel compounds, methods, compositions, and manufacturing methods to inhibit unwanted cell cycle in a host (e.g., a human), wherein said compounds can be used to treat abnormal cell proliferation. Another aspect of the present invention is to provide compounds, methods, and compositions that can be used to treat cell cycle disorders in cells that are naturally occurring or have become resistant to other therapies. Summary of the Invention

[0026] This invention provides therapeutically active compounds of formula I, II, III, IV, V, VI, VII, VIII, IX, or X, or pharmaceutically acceptable salts thereof, or combinations thereof. In some embodiments, the active compound, its salt, composition, or isotope analogue thereof is used in an effective amount to treat a medical condition involving abnormal cell proliferation in a host (typically, a human), including tumors or cancer.

[0027] In some embodiments, the compounds of the present invention are active against a variety of cyclin-dependent kinases, including, for example, preferential activity against CDK2. In some embodiments, the inhibitory selectivity of the compounds of the present invention against CDK2 is superior to that against CDK1, CDK3, CDK4, CDK5, CDK6, CDK7, and / or CDK9. Based on this finding, compounds and methods are provided for treating patients suffering from proliferative disorders, including tumors or cancer, comprising administering to a patient in need an effective amount of one or a combination of the compounds described herein or pharmaceutically acceptable salts thereof, optionally in a pharmaceutically acceptable carrier. In some embodiments, the antiproliferative disorder is selected from cancer, tumors, cysts, benign growths, autoimmune disorders, inflammatory disorders, graft-versus-host rejection, and fibrotic disorders. In a typical embodiment, the patient is a human being.

[0028] In some embodiments, the compounds of the present invention have high oral bioavailability, for example, oral bioavailability greater than about 50%, 60%, 70%, 80%, 90%, or 95% F (as the fraction of the drug that reaches systemic circulation intact). In some embodiments, the compounds of the present invention have high metabolic stability, for example, the compounds of the present invention can exhibit stability in human microsomes greater than about 30 minutes, 45 minutes, 1 hour, 1.5 hours, or 2 hours.

[0029] This invention also provides an advantageous method for treating patients with selective CDK4 / 6 inhibitor-resistant proliferative disorders such as tumors or cancers, comprising administering an effective amount of a compound of formula I, II, III, IV, V, VI, VII, VIII, IX, or X, or a pharmaceutically acceptable combination, salt, or isotope analog thereof. Despite the development of selective CDK4 / 6 inhibitors, MYC-driven tumor types with retinoblastoma (Rb) protein deficiency or high cyclin E expression levels, such as triple-negative breast cancer (TNBC) and small cell lung cancer (SCLC), are difficult to treat due to intrinsic or primary resistance to existing selective CDK4 / 6 inhibitors. Additionally, some cancers, although Rb-positive, exhibit intrinsic resistance to the effects of selective CDK4 / 6 inhibitors. Furthermore, some cancers with intact Rb pathways may exhibit intrinsic resistance to selective CDK4 / 6 inhibitors in other ways due to the presence of other genetic or phenotypic abnormalities. For example, it is estimated that despite Rb integrity, 40% of uterine cancers, 20% of ovarian cancers, 15% of bladder cancers, 20% of prostate cancers, and 15% of breast cancers may be intrinsically resistant to selective CDK4 / 6 inhibition due to upregulation of cyclin E. See, for example, Knudsen et al., The Strange Case of CDK4 / 6 Inhibitors: Mechanisms, Resistance, and Combination Strategies. Trends Cancer. 2017 Jan; 3(1):39–55. Furthermore, certain cancers, such as ER+ breast cancer, are able to acquire resistance to selective CDK4 / 6 inhibitors during selective CDK4 / 6 inhibitor therapy, for example, by upregulating cyclin E, which allows cell cycle progression from G1 to S via CDK2. In some embodiments, the compounds described herein effectively inhibit cell cycle progression in cancer cells that are intrinsically resistant to selective CDK4 / 6 inhibitors, readily acquire resistance to selective CDK4 / 6 inhibitors, or have become resistant to selective CDK4 / 6 inhibitors.

[0030] The active compounds described herein act as inhibitors of cyclin-dependent kinases (CDKs), providing cell cycle inhibition in replicating cells, for example, by inhibiting CDK2 and / or CDK4 and / or CDK6, or combinations thereof. However, unlike selective CDK4 / 6 inhibitors, some of the active compounds described herein are capable of inhibiting cells resistant to or having become resistant to selective CDK4 / 6 inhibitors by preferentially inhibiting another CDK (e.g., CDK2), thereby providing an additional cell cycle inhibition mechanism. In one embodiment, the present invention provides a selective CDK2 inhibitor. This property is particularly useful in inhibiting cell cycle progression in cancer or other Rb-negative or Rb-negative proliferative diseases that evade CDK4 / 6 cell cycle control.

[1056] As used in this article, the term "oxo" refers to the oxygen atom connected to the double bond.

[1057] As used herein, “intrinsic resistance,” also known as “primary resistance,” refers to a condition in which cancer does not respond to the inhibitory effect of initial CDK4 / 6 inhibitor treatment. Mutations and conditions associated with intrinsic resistance to CDK4 / 6 inhibitors include, but are not limited to: increased activity of cyclin-dependent kinase 1 (CDK1); increased activity of cyclin-dependent kinase 2 (CDK2); loss, absence, or absence (Rb-null) of retinoblastoma tumor suppressor protein (Rb); high levels of p16Ink4a expression; high levels of MYC expression; increased expression of cyclin E1, cyclin E2, and cyclin A; and combinations thereof. Cancer may be characterized by decreased expression of retinoblastoma tumor suppressor protein or one or more retinoblastoma family member proteins (such as, but not limited to, p107 and p130). In some embodiments, tumors or cancers with intrinsic resistance to selective CDK4 / 6 inhibitors are those whose cell population as a whole does not undergo substantial G1 cell cycle arrest upon exposure to the selective CDK4 / 6 inhibitor. In some implementations, the tumor or cancer that is intrinsically resistant to CDK4 / 6 inhibitors is a tumor or cancer having a cell population in which less than 25%, 20%, 15%, 10%, or 5% of its cells undergo G1 cell cycle arrest when exposed to a selective CDK4 / 6 inhibitor.

[1058] As used herein, “acquired resistance” refers to a condition in which cancers that were initially sensitive to or sensitive to the action of at least one selective CDK4 / 6 inhibitor become unresponsive or less responsive over time. Without wishing to be bound by any single theory, it is believed that acquired resistance to CDK4 / 6 inhibitors results from one or more additional mutations or genetic alterations in bypass signaling that occur after the initiation of a CDK4 / 6 inhibitor treatment regimen. For example, a non-limiting exemplary cause of acquired resistance to CDK4 / 6 inhibitors might be the development of one or more genetic aberrations associated with “intrinsic resistance.” Other non-limiting exemplary causes of acquired resistance to CDK4 / 6 inhibitors may include increased expression of cyclin E; CCNE1 / 2 amplification; E2F amplification; CDK2 amplification; CDK6 amplification; CDK4 amplification; p16 amplification; WEE1 overexpression; MDM2 overexpression; CDK7 overexpression; FZR1 deletion; HDAC activation; FGFR pathway activation; PI3K / AKT / mTOR pathway activation; loss of ER or PR expression; increased AP-1 transcriptional activity; epithelial-mesenchymal transition; Smad 3 inhibition; autophagy activation; Rb1 deletion or RB1 mutation inactivation; or combinations thereof. A general review of the mechanisms of CDK4 / 6 resistance can be found, for example, in Pandey et al., Molecular mechanisms of resistance to CDK4 / 6 inhibitors in breast cancer: A review. Int. J. Cancer: 00, 1–10 (2019), which is incorporated herein by reference. In some embodiments, acquired resistance to selective CDK4 / 6 inhibitors is defined as tumors or cancers whose cell population as a whole no longer undergoes substantial G1 cell cycle arrest upon exposure to the selective CDK4 / 6 inhibitor, thus preventing disease progression. In some embodiments, acquired resistance to CDK4 / 6 inhibitors is defined as tumors or cancers having a cell population in which less than 50%, 40%, 30%, 20%, 15%, 10%, or 5% of the cells undergo G1 cell cycle arrest upon exposure to the selective CDK4 / 6 inhibitor, thus preventing disease progression.

[1059] Intrinsic resistance to selective CDK4 / 6 inhibitors can be determined by any standard assay known to those skilled in the art, such as by measuring the absence or absence (Rb-null) of tumor suppressor proteins in retinoblastoma (Rb). For example, Rb status in cancer can be determined by, for example, but not limited to, Western blotting, ELISA (enzyme-linked immunosorbent assay), IHC (immunohistochemistry), and FACS (fluorescence-activated cell sorting). The choice of assay will depend on the tissue, cell line, or substitute tissue sample used; for example, Western blotting and ELISA can be used for any or all types of tissue, cell line, or substitute tissue, while IHC is more suitable when the tissue used in the methods described herein is a tumor biopsy. FACs analysis is best suited for samples that are single-cell suspensions, such as cell lines and isolated peripheral blood mononuclear cells. See, for example, US20070212736, “Functional Immunohistochemical Cell Cycle Analysis as a Prognostic Indicator for Cancer”.

[1060] Alternatively, molecular genetic testing can be used to determine the gene status of retinoblastoma. Molecular genetic testing for retinoblastoma includes the following, as described in Lohmann and Gallie, “Retinoblastoma. Gene Reviews” (2010) or Parsam et al., “A comprehensive, sensitive and economical approach for the detection of mutations in the RB1 gene in retinoblastoma”, Journal of Genetics, 88(4), 517-527 (2009).

[1061] Increased CDK1 or CDK2 activity, high levels of MYC expression, increased cyclin E, and increased cyclin A can be measured by any standard assay known to those skilled in the art, including but not limited to Western blotting, ELISA (enzyme-linked immunosorbent assay), IHC (immunohistochemistry), and FACS (fluorescence-activated cell sorting). The choice of assay will depend on the tissue, cell line, or substitute tissue sample used. For example, Western blotting and ELISA can be used for any or all types of tissue, cell line, or substitute tissue, while IHC is more suitable when the tissue used in the method is a tumor biopsy. FACs analysis is best suited for samples that are single-cell suspensions, such as cell lines and isolated peripheral blood mononuclear cells.

[1062] Many methods can be used to measure biomarkers believed to contribute to acquired resistance to CDK4 / 6 inhibitors. Current methods include immunohistochemistry (IHC), immunocytochemistry, and mass spectrometry. An alternative approach includes using immunofluorescence (IF) and image analysis to determine the relative abundance of proteins of interest in formalin-fixed, paraffin-embedded (FFPE) tissue samples. Immunohistochemistry (IHC) is the most commonly used method for determining gene expression levels, but Western blotting allows for the assessment of total expression as well as subtype-specific expression. Reverse transcription polymerase chain reaction (RT-PCR) can also be used to measure mRNA from genes of interest.

[1063] Immunohistochemistry (IHC) and immunocytochemistry (ICC) are techniques for localizing expression and rely on specific epitope-antibody interactions. IHC refers to the use of tissue sections, while ICC describes the use of cultured cells or cell suspensions. In both methods, positive staining is visualized using molecular markers, which can be fluorescent or chromogenic. In short, the sample is fixed to maintain cell integrity and then incubated with a blocking reagent to prevent non-specific antibody binding. The sample is then incubated with primary and secondary antibodies, and the signal is visualized for microscopic analysis.

[1064] Western blotting techniques use three elements to identify specific proteins in a complex mixture of proteins extracted from cells: separation by size, transfer to a solid support, and labeling the target protein with appropriate primary and secondary antibodies for visualization. The most common form of this method is immunoblotting. This technique is used to detect specific proteins in a given tissue homogenate or extract sample. The protein sample is first subjected to SDS-PAGE electrophoresis to separate proteins based on molecular weight. The proteins are then transferred to a membrane, where they are detected using antibodies specific to the target protein.

[1065] Genomic alterations and mRNA expression can be determined using fluorescence in situ hybridization (FISH), targeted sequencing, and microarray analysis. Common mutated genes, as well as differentially expressed and co-expressed genes, can be identified.

[1066] Fluorescence in situ hybridization (FISH) is a cytogenetic technique used to detect and locate RNA sequences within tissues or cells. This is particularly important for defining spatiotemporal patterns of gene expression. FISH relies on fluorescent probes that bind to complementary sequences of the RNA of interest. A series of hybridization steps are performed to amplify the signal from the target of interest. This amplification is then observed using a fluorescence microscope. This technique can be used with formalin-fixed paraffin-embedded (FFPE) tissues, frozen tissues, fresh tissues, cells, and circulating tumor cells.

[1067] Targeted RNA sequencing (RNA-Seq) is a highly precise method for selecting and sequencing specific transcripts of interest. It provides both quantitative and qualitative information. Targeted RNA-Seq can be performed via enrichment or amplicon-based methods, both of which allow for gene expression analysis within a concentrated set of genes of interest. Enrichment assays also provide the ability to detect known and novel gene fusion pairings in many sample types, including formalin-fixed paraffin-embedded (FFPE) tissue. RNA enrichment provides quantitative expression information as well as the detection of minor variations and gene fusions.

[1068] In microarray analysis, mRNA molecules are typically collected from both experimental and reference samples. For example, reference samples can be collected from healthy individuals, and experimental samples can be collected from individuals with diseases such as cancer. The two mRNA samples are then converted into complementary DNA (cDNA), and each sample is labeled with a different colored fluorescent probe. The experimental cDNA sample is labeled with a red fluorescent dye, while the reference cDNA is labeled with a green fluorescent dye. The two samples are then mixed together and allowed to hybridize with a microarray slide. After hybridization, the microarray is scanned to measure the expression of each gene printed on the slide. If the expression of a particular gene in the experimental sample is higher than in the reference sample, the corresponding point on the microarray is displayed in red. Conversely, if the expression in the experimental sample is lower than in the reference sample, the point is displayed in green. Finally, if the expression in both samples is the same, the point is displayed in yellow. The data collected through the microarray can be used to create gene expression profiles that show the simultaneous changes in the expression of many genes in response to specific conditions or treatments.

[1069] The term “selective CDK4 / 6 inhibitor” as used in the context of the compounds described herein includes compounds that inhibit CDK4 activity, CDK6 activity, or both CDK4 and CDK6 activity at an IC50 molar concentration at least about 300, 400, 500, 1000, 1500, 1800, 2000, 5000, or 10,000 times lower than the IC50 molar concentration required to inhibit the same degree of CDK2 activity in a standard phosphorylation assay.

[1070] In the context of the compounds described herein, the term "N-oxide" refers to the oxidized form of a molecule in which nitrogen is oxidized. Any nitrogen on any molecule described herein can be oxidized.

[1071] As a non-limiting embodiment, the N-oxide of compound 1 can be:

[1072]

[1073] In some embodiments, any active compound may be provided to the patient in need in N-oxide form. In some embodiments, the N-oxide of the active compound or a precursor of the active compound is used in the manufacturing process. In other embodiments, the N-oxide is an administered metabolite of one of the active compounds described herein and may have independent activity. Using techniques known to those skilled in the art, N-oxides can be formed by treating the compound of interest with an oxidizing agent (e.g., a suitable peroxyacid or peroxide) to generate an N-oxide compound. For example, an N-oxide compound can be generated by treating a heteroaryl group, such as a pyrimidine group, with an oxidizing agent such as sodium percarbonate under mild reaction conditions in the presence of a metal catalyst. Those skilled in the art will understand that carrying out this chemical reaction may require appropriate protecting groups. See Jain, SL et al., “Rhenium-Catalyzed Highly Efficient Oxidations of Tertiary Nitrogen Compounds to N-Oxides Using Sodium Percarbonate as Oxygen Source,” Synlett, 2261-2663, 2006.

[1086] In another implementation, the condition is myelodysplastic syndrome (MDS).

[1087] In some implementations, the cancer is a hematopoietic carcinoma. In some implementations, the hematopoietic carcinoma is a lymphoma. In some implementations, the hematopoietic carcinoma is leukemia. In some implementations, the leukemia is acute myeloid leukemia.

[1088] In some implementations, the proliferative condition is myeloproliferative neoplasm. In some implementations, myeloproliferative neoplasm (MPN) is primary myelofibrosis (PMF).

[1089] In some implementations, cancer is defined as a solid tumor. As used herein, a solid tumor is an abnormal mass of tissue that does not typically contain cysts or fluid-filled areas. Different types of solid tumors are named after the type of cells that form them. Examples of solid tumor categories include, but are not limited to, sarcomas, carcinomas, and lymphomas, as described above herein. Other examples of solid tumors include, but are not limited to, squamous cell carcinoma, colon cancer, breast cancer, prostate cancer, lung cancer, liver cancer, pancreatic cancer, and melanoma.

[1090] In some implementations, patients treated with Formula I, Formula II, Formula III, Formula IV, Formula V, Formula VI, Formula VII, Formula VIII, Formula IX, or Formula X are patients with conditions related to abnormal cell proliferation.

[1091] Abnormal cell proliferation, especially excessive proliferation, can be the result of a wide range of factors, including gene mutations, infection, exposure to toxins, autoimmune diseases, and induction by benign or malignant tumors.

[1092] Many skin conditions are associated with excessive cell proliferation. For example, psoriasis is a benign skin disease characterized by plaques typically covered with thickened scales. This disease is caused by an unexplained increase in the proliferation of epidermal cells. Chronic eczema is also associated with significant excessive proliferation of the epidermis. Other conditions caused by excessive proliferation of skin cells include atopic dermatitis, lichen planus, warts, pemphigus vulgaris, actinic keratosis, basal cell carcinoma, and squamous cell carcinoma.

[1093] Other proliferative cell disorders include angiogenesis disorders, fibrosis disorders, autoimmune disorders, graft-versus-host rejection, tumors, and cancer.

[1094] Angiogenic disorders include both angiogenesis and vascularization disorders. The proliferation of smooth muscle cells during plaque development in vascular tissue leads to conditions such as restenosis, retinopathy, and atherosclerosis. Both cell migration and cell proliferation play a role in the formation of atherosclerotic lesions.

[1095] Fibrotic disorders are often caused by abnormal formation of the extracellular matrix. Examples of fibrotic disorders include cirrhosis and mesangial proliferative cell disease. Cirrhosis is characterized by an increase in extracellular matrix components leading to liver scarring. Cirrhosis can cause diseases such as liver cirrhosis. The increase in extracellular matrix leading to liver scarring can also be caused by viral infections such as hepatitis. Adipocytes appear to play a major role in cirrhosis.

[1096] Mesangial disorders are caused by the abnormal proliferation of mesangial cells. Mesangial hyperproliferative cell disorders include various human kidney diseases such as glomerulonephritis, diabetic nephropathy, malignant nephrocisic nephropathy, thrombotic microangiopathy syndrome, transplant rejection, and glomerulonephropathy.

[1097] Another disease with a proliferative component is rheumatoid arthritis. Rheumatoid arthritis is generally considered an autoimmune disease, believed to be associated with the activity of autoreactive T cells and caused by autoantibodies produced against collagen and IgE.

[1098] Other conditions that may include abnormal cell proliferation components include Bechet syndrome, acute respiratory distress syndrome (ARDS), ischemic heart disease, postdialysis syndrome, leukemia, acquired immunodeficiency syndrome, vasculitis, lipohistiocytosis, septic shock, and general inflammation.

[1099] In some embodiments, the compounds of the present invention and their pharmaceutically acceptable derivatives, or pharmaceutically acceptable formulations containing these compounds, may also be used for the prevention and treatment of HBV infection and other related conditions such as anti-HBV antibody-positive and HBV-positive patients, chronic liver inflammation caused by HBV, cirrhosis, acute hepatitis, fulminant hepatitis, chronic persistent hepatitis, and fatigue. These compounds or formulations may also be used prophylactically to prevent or delay the clinical progression of disease in individuals who are positive for anti-HBV antibodies or HBV-antigens, or individuals who have been exposed to HBV.

[1100] In some implementations, the patient is associated with an immune response.

[1101] Skin contact hypersensitivity and asthma are just two examples of immune responses that may be associated with a significant incidence rate. Others include atopic dermatitis, eczema, Sjögren's syndrome (including keratoconjunctivitis sicca secondary to Sjögren's syndrome), alopecia areata, allergic reactions to arthropod bites, Crohn's disease, aphthous ulcers, iritis, conjunctivitis, keratoconjunctivitis, ulcerative colitis, cutaneous lupus erythematosus, scleroderma, vaginitis, proctitis, and drug eruptions. These conditions may cause any one or more of the following symptoms or signs: itching, swelling, redness, blisters, crusting, ulceration, pain, scaling, cracking, hair loss, scarring, or fluid exudation involving the skin, eyes, or mucous membranes.

[1102] In atopic dermatitis and eczema general, immune-mediated leukocyte infiltration (particularly monocytes, lymphocytes, neutrophils, and eosinophils) into the skin is a significant factor in the pathogenesis of these diseases. Chronic eczema is also associated with significant epidermal hyperplasia. Immune-mediated leukocyte infiltration also occurs in sites outside the skin, such as in the airways of asthmatic patients and in the lacrimal glands of the eyes of patients with keratoconjunctivitis sicca.

[1103] In one non-limiting embodiment, the compounds of the present invention are used as topical medications for treating contact dermatitis, atopic dermatitis, eczematous dermatitis, psoriasis, Sjögren's syndrome (including keratoconjunctivitis sicca secondary to Sjögren's syndrome), alopecia areata, allergic reactions to arthropod bites, Crohn's disease, aphthous ulcers, iritis, conjunctivitis, keratoconjunctivitis, ulcerative colitis, asthma, allergic asthma, cutaneous lupus erythematosus, scleroderma, vaginitis, proctitis, and drug eruptions. This novel approach can also be used to reduce the infiltration of malignant leukocytes into the skin in diseases such as mycosis fungoides. By applying the compounds topically to the eyes, these compounds can also be used to treat dehydrated dry eye syndrome (such as immune-mediated keratoconjunctivitis) in patients with dehydrated dry eye syndrome.

[1104] Throughout this document, the terms “tumor formation” or “cancer” refer to the pathological process leading to the formation and growth of a cancerous or malignant tumor. Specifically, through cell proliferation, abnormal tissue (solid) or cells (non-solid) often grows faster than normal tissue or cells and continues to grow after the stimulus that initiated new growth ceases. Malignant tumors are characterized by a partial or complete lack of structural tissue and functional coordination with normal tissue, and most invade surrounding tissues, can metastasize to multiple sites, are likely to recur after attempted removal, and can lead to patient death unless adequately treated. As used herein, the term tumor formation is used to describe all cancerous disease states and includes or encompasses the pathological processes associated with malignant hematogenous, ascites, and solid tumors. Exemplary cancers that can be treated alone or in combination with at least one other anticancer agent by the compounds of this disclosure include squamous cell carcinoma, basal cell carcinoma, adenocarcinoma, hepatocellular carcinoma and renal cell carcinoma, bladder cancer, head cancer, kidney cancer, neck cancer, leukemia; benign and malignant lymphomas, particularly Burkitt lymphoma and non-Hodgkin lymphoma; benign and malignant melanomas; myeloproliferative disorders; sarcomas, including Ewing's sarcoma, angiosarcoma, Kaposi's sarcoma, liposarcoma, myxosarcoma, peripheral neuroepithelial tumor, synovial sarcoma, and glioma.

[1106] In another aspect, a method is provided for increasing BIM expression (e.g., BCLC2L11 expression) to induce apoptosis in cells, comprising contacting cells with a compound of the present invention or a pharmaceutically acceptable composition, salt, or isotope analog thereof. In some embodiments, the method is an in vitro method. In some embodiments, the method is an in vivo method. BCL2L11 expression is tightly regulated in cells. BCL2L11 encodes BIM, a pro-apoptotic protein. BCL2L11 is downregulated in many cancers, BIM is inhibited in many cancers, including chronic myeloid leukemia (CML) and non-small cell lung cancer (NSCLC), and inhibition of BCL2L11 expression can confer resistance to tyrosine kinase inhibitors. See, for example, Ng et al., Nat. Med. (2012) 18:521–528.

[1107] In another aspect, a method is provided for treating patients with angiogenesis-related conditions such as diabetic patients (e.g., diabetic retinopathy), inflammatory patients (e.g., rheumatoid arthritis), macular degeneration, obesity, atherosclerosis, or proliferative disorders, comprising administering to a subject in need a compound of the invention or a pharmaceutically acceptable composition, salt, or isotope analog thereof.

[1108] In some embodiments, the patient associated with angiogenesis has macular degeneration. In some embodiments, a method of treating macular degeneration is provided, comprising administering to a subject in need a compound of the present invention or a pharmaceutically acceptable composition, salt, or isotope analog thereof.

[1109] In some embodiments, the patient associated with angiogenesis is obese. As used herein, “obesity” and “obesity” as used herein refer to Group I obesity, Group II obesity, Group III obesity, and pre-obesity (e.g., “overweight”) as defined by the World Health Organization. In some embodiments, a method of treating obesity is provided, comprising administering to a subject in need of the compound of the present invention or a pharmaceutically acceptable composition, salt, or isotope analog thereof.

[1110] In some embodiments, the patient associated with angiogenesis is atherosclerosis. In some embodiments, a method of treating atherosclerosis is provided, comprising administering to a subject in need of the compound of the present invention or a pharmaceutically acceptable composition, salt, or isotope analog thereof.

[1111] In some embodiments, the condition associated with angiogenesis is a proliferative disorder. In some embodiments, a method of treating a proliferative disorder is provided, comprising administering to a subject in need a compound of the present invention or a pharmaceutically acceptable composition, salt, or isotope analog thereof.

[1112] IV. Methods to reduce chemotherapy-related side effects

[1113] In some embodiments, the compounds of the present invention reduce the effects of chemotherapeutic agent toxicity on CDK4 / 6 replication-dependent healthy cells, such as hematopoietic stem cells and hematopoietic progenitor cells (collectively, HSPCs) and / or renal epithelial cells, in subjects (typically, humans) that will be, are, or have been exposed to chemotherapeutic agents (typically DNA-damaging agents).

[1114] In some embodiments, the subject has been exposed to a chemotherapeutic agent, and using the compound described herein, the subject's CDK4 / 6-replication-dependent healthy cells are placed in G1 blockade after exposure to mitigate, for example, DNA damage. In some embodiments, the compound is administered at least 1 / 2 hour, at least 1 hour, at least 2 hours, at least 3 hours, at least 4 hours, at least 5 hours, at least 6 hours, at least 7 hours, at least 8 hours, at least 10 hours, at least 12 hours, at least 14 hours, at least 16 hours, at least 18 hours, at least 20 hours, or longer after exposure to the chemotherapeutic agent.

[1115] In some embodiments, the compound may allow for dose intensification in medically relevant chemotherapy (e.g., more treatment can be administered over a fixed period of time), which translates into better efficacy. Therefore, the currently disclosed methods can produce chemotherapy regimens that are less toxic and more effective.

[1116] In some embodiments, the use of the compounds described herein may result in reduced or substantially no off-target effects, for example, in connection with the inhibition of kinases other than CDK4 and / or CDK6 and / or CDK2. Furthermore, in some embodiments, the use of the compounds described herein should not induce cell cycle arrest in CDK4 / 6 replication-independent cells.

[1117] In some embodiments, the use of the compounds described herein reduces the risk of undesirable off-target effects, including but not limited to long-term toxicity, antioxidant effects, and estrogenic effects. Antioxidant effects can be determined by standard assays known in the art. For example, a compound without significant antioxidant effects is one that does not significantly scavenge free radicals such as oxygen free radicals. The antioxidant effect of a compound can be compared to that of a compound with known antioxidant activity, such as genistein. Therefore, a compound without significant antioxidant activity can be one with antioxidant activity less than about 2, 3, 5, 10, 30, or 100 times that of genistein. Estrogenic activity can also be determined by known assays. For example, a non-estrogenous compound is one that does not significantly bind to and activate estrogen receptors. A compound with substantially no estrogenic effect can be one with estrogenic activity less than about 2, 3, 5, 10, 20, or 100 times that of a compound with estrogenic activity, such as genistein.

[1118] V. Methods for treating abnormal proliferation of T cells, B cells, and / or NK cells

[1119] In some aspects, the present invention includes optionally using an effective amount of the compounds described herein, or pharmaceutically acceptable salts thereof, or isotope analogs thereof, in a pharmaceutical composition to treat a host (typically, a human) suffering from selected cancers, tumors, hyperproliferative disorders, or inflammatory or immune conditions. Some of the disclosed compounds are highly active against T-cell proliferation. Given the lack of drugs targeting T-cell cancers and abnormal proliferation, the determination of such use represents a substantial improvement in the medical treatment of these diseases.

[1120] Abnormal proliferation of T cells, B cells, and / or NK cells can lead to a wide range of diseases, such as cancer, proliferative disorders, and inflammatory / immune diseases. Hosts (e.g., humans) suffering from any of these conditions can be treated with effective amounts of compounds as described herein to achieve symptom relief (palliative agents) or reduction of underlying disease (disease modulators).

[1121] Examples include T-cell or NK-cell lymphomas, such as, but not limited to: peripheral T-cell lymphoma; anaplastic large cell lymphoma, such as anaplastic lymphoma kinase (ALK) positive, ALK negative anaplastic large cell lymphoma, or primary cutaneous anaplastic large cell lymphoma; autoimmune blastic lymphoma; cutaneous T-cell lymphoma, such as mycosis fungoides, Sézary syndrome, primary cutaneous anaplastic large cell lymphoma, primary cutaneous CD30+ T-cell lymphoproliferative disorder; primary cutaneous aggressive epidermophilic CD8+ cytotoxic T-cell lymphoma; primary cutaneous γ-δ T-cell lymphoma; primary cutaneous small / medium CD4+ T-cell lymphoma and lymphomatoid papulosis; adult T-cell leukemia / lymphoma.

[1122] In some embodiments, the compounds disclosed herein, or their salts or isotope analogs thereof, can be used in effective amounts to treat a host (e.g., a human) suffering from lymphoma or a lymphocytic or myeloid cell proliferation disorder or abnormality. For example, compounds as described herein can be administered to a host suffering from Hodgkin lymphoma or non-Hodgkin lymphoma. For example, the host may have non-Hodgkin's lymphoma, such as, but not limited to: AIDS-related lymphoma; anaplastic large cell lymphoma; autoimmune blastic lymphoma; blastic NK cell lymphoma; Burkitt lymphoma; Burkitt-like lymphoma (small non-cleaved cell lymphoma); chronic lymphocytic leukemia / small lymphocytic leukemia; cutaneous T-cell lymphoma; diffuse large B-cell lymphoma; enteropathy-type T-cell lymphoma; follicular lymphoma; hepatosplenic γ-δ T-cell lymphoma; lymphoblastic lymphoma; mantle cell lymphoma; marginal zone lymphoma; nasal T-cell lymphoma; pediatric lymphoma; peripheral T-cell lymphoma; primary central nervous system lymphoma; T-cell leukemia; transformed lymphoma; treatment-associated T-cell lymphoma; or Waldenström macroglobulinemia.

[1123] Alternatively, the compounds disclosed herein, or their salts or isotope analogs thereof, may be used in effective amounts to treat a host (e.g., a human) with Hodgkin lymphoma, such as, but not limited to: tuberous sclerosis classical Hodgkin lymphoma (CHL); mixed cellularity CHL; lymphocyte-depleted CHL; lymphocyte-rich CHL; lymphocyte-dominant Hodgkin lymphoma; or nodular lymphocyte-dominant HL.

[1124] Alternatively, the compounds disclosed herein, or their salts or isotope analogs thereof, may be used in effective amounts to treat hosts (e.g., humans) with specific B-cell lymphomas or proliferative disorders, such as, but not limited to: multiple myeloma; diffuse large B-cell lymphoma; follicular lymphoma; mucosa-associated lymphoid tissue lymphoma (MALT); small cell lymphocytic lymphoma; mediastinal large B-cell lymphoma; lymph node marginal zone B-cell lymphoma (NMZL); spleen marginal zone lymphoma (SMZL); intravascular large B-cell lymphoma; primary exudative lymphoma; or lymphomatoid granulomatosis; B-cell prelymphocytic leukemia; hairy cell leukemia; unclassifiable splenic lymphoma / leukemia; diffuse red pulp small B-cell lymphoma of the spleen; hairy cell leukemia-variant; lymphoplasmacytic lymphoma; heavy chain disease; For example, alpha heavy chain disease, gamma heavy chain disease, μ heavy chain disease; plasma cell myeloma; solitary osteoplasmacytoma; extraosseous plasmacytoma; primary cutaneous follicular center lymphoma; T-cell / histiocytic abundant large B-cell lymphoma; DLBCL associated with chronic inflammation; EBV-positive elderly DLBCL; primary mediastinal (thymic) large B-cell lymphoma; primary cutaneous DLBCL, leg type; ALK+ large B-cell lymphoma, plasmablastic lymphoma; large B-cell lymphoma in HHV8-associated multicentric Castleman disease; B-cell lymphoma, unclassifiable, with features between diffuse large B-cell lymphoma; or B-cell lymphoma, unclassifiable, with features between diffuse large B-cell lymphoma and classical Hodgkin lymphoma.

[1125] In some embodiments, the compounds disclosed herein, or their salts or isotope analogs thereof, can be used in effective amounts to treat a host (e.g., a human) suffering from leukemia. For example, the host may be suffering from acute or chronic leukemia of lymphocytic or bone marrow origin, such as, but not limited to: acute lymphoblastic leukemia (ALL); acute myeloid leukemia (AML); chronic lymphocytic leukemia (CLL); chronic myeloid leukemia (CML); juvenile myelomonocytic leukemia (JMML); hairy cell leukemia (HCL); acute promyelocytic leukemia (a subtype of AML); large granular lymphocytic leukemia; or adult T-cell chronic leukemia. In some implementations, the patient has acute myeloid leukemia, such as undifferentiated AML (M0); myeloblastic leukemia (M1; with / without minimum cell maturation); myeloblastic leukemia (M2; with cell maturation); promyelocytic leukemia (M3 or M3 variant [M3V]); myelomonocytic leukemia (M4 or M4 variant [M4E] with eosinophilia); monocytic leukemia (M5); erythroleukemia (M6); or megakaryoblastic leukemia (M7).

[1126] VI. Pharmaceutical Compositions and Dosage Forms

[1127] The active compounds described herein, or their salts or isotopic analogs, may be administered to the host in an effective amount using any suitable method to achieve the desired therapeutic outcome to treat any of the conditions described herein. Of course, the dosage and timing of administration of the active compound will depend on the host being treated, the instructions of the attending medical professional, the duration of exposure, the method of administration, the pharmacokinetic properties of the specific active compound, and the judgment of the prescribing physician. Therefore, due to variability among hosts, the dosages given below are guidelines, and physicians may adjust the dosage of the compound to achieve the treatment deemed appropriate for the host by the physician. In considering the required level of treatment, physicians may balance various factors such as the host's age and weight, pre-existing conditions, and the presence of other illnesses.

[1128] Pharmaceutical compositions can be formulated into any pharmaceutically useful form, such as aerosols, creams, gels, pills, injectable or infusion solutions, capsules, tablets, syrups, transdermal patches, subcutaneous patches, dry powders, inhaled formulations, medical devices, suppositories, buccal or sublingual formulations, parenteral formulations, or ophthalmic solutions. Some dosage forms, such as tablets and capsules, are subdivided into appropriately sized unit doses containing a suitable amount of the active ingredient, such as an effective amount to achieve the desired purpose.

[1129] The therapeutically effective dose of any active compound described herein will be determined by a healthcare professional based on the patient's condition, body type, age, and route of delivery. In one non-limiting embodiment, a dose of about 0.1 to about 200 mg / kg is therapeutically effective, all weights being calculated based on the weight of the active compound, including in the case of saline. In some embodiments, the dose is about or greater than 0.1, 0.5, 1, 5, 10, 25, 50, 75, 100, 125, 150, 175, or 200 mg / kg.

[1133] According to the currently disclosed methods, oral administration can be in any desired form, such as solid, gel, or liquid, including solutions, suspensions, or emulsions. In some embodiments, the compound or salt is administered as a liposome suspension via inhalation, intravenous, or intramuscular administration. When administered by inhalation, the active compound or salt can be in the form of multiple solid particles or droplets having any desired particle size, for example, from about 0.01, 0.1, or 0.5 to about 5, 10, 20 micrometers or larger, and optionally from about 1 to about 2 micrometers. The compounds disclosed in this invention have demonstrated favorable pharmacokinetic and pharmacodynamic properties, for example, when administered via oral or intravenous routes.

[1134] Pharmaceutical formulations may contain the active compound described herein or a pharmaceutically acceptable salt thereof in any pharmaceutically acceptable carrier. If a solution is required, water may sometimes be the preferred carrier for water-soluble compounds or salts. For water-soluble compounds or salts, organic mediators such as glycerol, propylene glycol, polyethylene glycol, or mixtures thereof may be suitable. In the latter case, the organic mediator may contain a significant amount of water. The solution in either case may then be sterilized in a manner known to those skilled in the art, for example, by filtration through a 0.22-micron filter. After sterilization, the solution may be dispensed into appropriate containers, such as pyrogen-free glass vials. Dispensing may optionally be performed aseptically. A sterile cap may then be placed on the vial, and the contents of the vial may be lyophilized if necessary.

[1135] The carrier comprises excipients and diluents and must possess sufficiently high purity and low toxicity to be suitable for administration to the treated patient. The carrier may be inert or possess its own pharmaceutical benefits. The amount of carrier used in conjunction with the compound is sufficient to provide a practical amount of application material per unit dose of the compound.

[1136] Carriers include, but are not limited to, binders, buffers, colorants, diluents, disintegrants, emulsifiers, flavoring agents, gliding agents, lubricants, preservatives, stabilizers, surfactants, tableting agents, and wetting agents. Some carriers may be listed in more than one category; for example, vegetable oils may be used as lubricants in some formulations and as diluents in others. Exemplary pharmaceutically acceptable carriers include sugars, starches, cellulose, powdered tragacanth gum, malt, gelatin; talc, and vegetable oils. Pharmaceutical compositions may contain optional active agents that do not substantially interfere with the activity of the compounds of the present invention.

[1137] In addition, auxiliary substances, such as wetting agents or emulsifiers, biological buffers, and surfactants, can be present in such media. Biological buffers can be any pharmacologically acceptable solution, and they provide the required pH for the formulation, i.e., a pH within a physiologically acceptable range. Examples of buffer solutions include saline, phosphate-buffered saline, Tris-buffered saline, Hank's buffered saline, etc.

[1138] Depending on the intended mode of administration, the pharmaceutical composition may be in the form of a solid, semi-solid, or liquid dosage form, such as tablets, suppositories, pills, capsules, powders, liquids, suspensions, creams, ointments, lotions, etc., preferably a single-dose unit dosage form suitable for precise dosing. The composition will contain an effective amount of the selected drug combined with a pharmaceutically acceptable carrier, and may also contain other pharmaceutical agents, adjuvants, diluents, buffers, etc.

[1139] Therefore, the compositions disclosed herein can be administered as pharmaceutical preparations, including those suitable for oral (including buccal and sublingual), rectal, nasal, topical, pulmonary, vaginal, or parenteral (including intramuscular, intra-arterial, intrathecal, subcutaneous, and intravenous) administration, or in forms suitable for inhalation or insufflation. Preferred administration methods are intravenous or oral, using convenient daily dosing regimens that can be adjusted according to the degree of discomfort.

[1140] For solid compositions, conventional non-toxic solid carriers include, for example, pharmaceutical-grade mannitol, lactose, starch, magnesium stearate, sodium saccharin, talc, cellulose, glucose, sucrose, magnesium carbonate, etc. Compositions suitable for liquid pharmaceutical administration can be prepared, for example, by dissolving, dispersing, etc., the active compound as described herein and optional adjuvants in an excipient such as water, saline, dextran aqueous solution, glycerol, ethanol, etc., to form a solution or suspension. If desired, the pharmaceutical composition to be administered may also contain small amounts of non-toxic excipients, such as wetting agents or emulsifiers, pH buffers, etc., for example, sodium acetate, sorbitol monolaurate, triethanolamine acetate sodium, triethanolamine oleate, etc. Practical methods for preparing such dosage forms are known or will be obvious to those skilled in the art; see, for example, Remington's Pharmaceutical Sciences cited above.

[1141] In another embodiment, for the use of a penetration enhancer excipient, the penetration enhancer excipient includes polymers such as: polycationic (chitosan and its quaternary ammonium derivatives, poly-L-arginine, amination gelatin); polyanionic (N-carboxymethyl chitosan, polyacrylic acid); and thiolized polymers (carboxymethyl cellulose-cysteine, polycarbofil-cysteine, chitosan-thiobutylamidine, chitosan-thioglycolic acid, chitosan-glutathione conjugate).

[1142] For oral administration, the compositions are typically in the form of tablets, capsules, soft gel capsules, or may be aqueous or non-aqueous solutions, suspensions, or syrups. Tablets and capsules are preferred forms for oral administration. Tablets and capsules for oral use may contain one or more commonly used carriers, such as lactose and corn starch. Lubricants, such as magnesium stearate, are often also added. Typically, the compositions of this disclosure can be combined with oral, non-toxic, pharmaceutically acceptable inert carriers such as lactose, starch, sucrose, glucose, methylcellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, mannitol, sorbitol, etc. In addition, suitable binders, lubricants, disintegrants, and colorants may be introduced into the mixture when desired or necessary. Suitable binders include starch, gelatin, natural sugars such as glucose or β-lactose, corn sweeteners, natural and synthetic gums such as gum arabic, tragacanth, or sodium alginate, carboxymethyl cellulose, polyethylene glycol, waxes, etc. The lubricants used in these formulations include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, and sodium chloride. Disintegrants include, but are not limited to, starch, methylcellulose, agar, bentonite, and xanthan gum.

[1143] When using liquid suspensions, the active agent may be combined with any orally administered, non-toxic, pharmaceutically acceptable inert carrier such as ethanol, glycerol, water, etc., as well as with emulsifiers and suspending agents. Flavoring agents, coloring agents, and / or sweeteners may also be added if desired. Other optional components introduced into the oral formulations herein include, but are not limited to, preservatives, suspending agents, thickeners, etc.

[1144] Parenteral formulations can be prepared in conventional forms, or in the form of liquid solutions or suspensions, solid forms suitable for dissolution or suspension in a liquid prior to injection, or emulsions. Preferably, sterile injectable suspensions are formulated using suitable carriers, dispersants or wetting agents, and suspending agents according to techniques known in the art. Sterile injectable formulations can also be sterile injectable solutions or suspensions in non-toxic parenteral diluents or solvents. Acceptable media and solvents that can be used include water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile non-volatile oils, fatty esters, or polyols are commonly used as solvents or suspension media. Furthermore, parenteral administration may involve the use of slow-release or sustained-release systems to maintain a constant dose level.

[1145] Parenteral administration includes intra-articular, intravenous, intramuscular, intradermal, intraperitoneal, and subcutaneous routes, and includes aqueous and non-aqueous isotonic sterile injectable solutions that may contain antioxidants, buffers, antibacterial agents, and solutes that make the formulation isotonic with the blood of the intended recipient, as well as aqueous and non-aqueous sterile suspensions that may contain suspending agents, solubilizers, thickeners, stabilizers, and preservatives. Administration via certain parenteral routes may involve introducing the formulations of this disclosure into the patient through a needle or catheter propelled by a sterile syringe or some other mechanical device such as a continuous infusion system. The formulations provided in this disclosure can be administered using a syringe, injector, pump, or any other device recognized in the art for parenteral administration.

[1146] In addition to the active compound or its salts, pharmaceutical formulations may contain other additives, such as pH-adjusting additives. Specifically, available pH adjusters include acids such as hydrochloric acid, bases, or buffers such as sodium lactate, sodium acetate, sodium phosphate, sodium citrate, sodium borate, or sodium gluconate. Furthermore, formulations may contain antimicrobial preservatives. Available antimicrobial preservatives include methylparaben, propylparaben, and benzyl alcohol. Antimicrobial preservatives are typically used when formulations are packaged in vials designed for multiple-dose administration. The pharmaceutical formulations described herein may be lyophilized using techniques well known in the art.

[1147] For oral administration, pharmaceutical compositions can be in the form of solutions, suspensions, tablets, pills, capsules, powders, etc. Tablets containing various excipients such as sodium citrate, calcium carbonate, and calcium phosphate can be used with various disintegrants such as starch (e.g., potato or cassava starch) and certain complex silicates, as well as binders such as polyvinylpyrrolidone, sucrose, gelatin, and gum arabic. Additionally, lubricants such as magnesium stearate, sodium lauryl sulfate, and talc are often very useful for tableting purposes. Similar types of solid compositions can be used as fillers in soft and hard-filled gelatin capsules. Materials in this regard also include lactose or milk sugar and high molecular weight polyethylene glycol. When aqueous suspensions and / or elixirs are required for oral administration, the compounds of the disclosed subject matter can be used in combination with various sweeteners, flavoring agents, coloring agents, emulsifiers and / or suspending agents, as well as diluents such as water, ethanol, propylene glycol, glycerin, and various similar combinations thereof.

[1148] In another embodiment of the subject matter described herein, an injectable, stable, sterile formulation in a sealed container, in unit dosage form, is provided, comprising an active compound or a salt thereof as described herein. The compound or salt is provided in lyophilized form, which can be reconstituted with a suitable pharmaceutically acceptable carrier to form a liquid formulation suitable for injection into a host. When the compound or salt is substantially insoluble in water, a physiologically acceptable sufficient amount of emulsifier can be used to emulsify the compound or salt in an aqueous carrier. Particularly useful emulsifiers include phosphatidylcholine and lecithin.

[1149] Other embodiments include liposome formulations of the active compounds disclosed herein. Techniques for forming liposome suspensions are well known in the art. When the compound is a water-soluble salt, it can be incorporated into lipid vesicles using conventional liposome techniques. In this case, due to the water solubility of the active compound, it can be substantially encased within the hydrophilic center or core of the liposome. The lipid layer used can be of any conventional composition and may or may not contain cholesterol. When the active compound of interest is water-insoluble, conventional liposome formation techniques are also used, and the salt can be substantially encased within a hydrophobic lipid bilayer forming the liposome structure. In either case, the resulting liposomes can be reduced in size, such as by using standard sonication and homogenization techniques. Liposome formulations containing the active compounds disclosed herein can be lyophilized to produce lyophilized products, which can be reconstituted using pharmaceutically acceptable carriers such as water to regenerate the liposome suspension.

[1150] Pharmaceutical formulations suitable for aerosol administration via inhalation are also provided. These formulations comprise a solution or suspension of a desired compound or salt thereof described herein, or multiple solid particles of said compound or salt. The desired formulation can be placed in a chamber and nebulized. Nebulization can be accomplished by compressed air or by ultrasonic energy to form multiple liquid droplets or solid particles containing said compound or salt. The liquid droplets or solid particles may, for example, have a particle size in the range of about 0.5 to about 10 micrometers, optionally about 0.5 to about 5 micrometers. In some embodiments, the solid particles provide controlled release by using a biodegradable polymer. The solid particles can be obtained by processing a solid compound or salt thereof in any suitable manner known in the art, such as by micronization. Optionally, the size of the solid particles or droplets may be about 1 to about 2 micrometers. In this regard, commercial nebulizers can be used to achieve this purpose. The compound can be administered via an aerosol suspension of breathable particles in the manner set forth in U.S. Patent No. 5,628,984, the disclosure of which is incorporated herein by reference in its entirety.

[1151] Pharmaceutical formulations that provide controlled release of the compounds described herein are also provided, including by using biodegradable polymers as known in the art.

[1152] When a pharmaceutical formulation suitable for aerosol application is in liquid form, the formulation may contain a water-soluble active compound in a water-containing carrier. A surfactant may be present, which sufficiently reduces the surface tension of the formulation to form droplets within the desired size range upon atomization.

[1153] As used herein, the term "pharmaceutically acceptable salt" means those salts that are suitable for use in contact with a host (e.g., a human host) without excessive toxicity, irritation, allergic reactions, etc., within the bounds of reasonable medical judgment, and that are effective for their intended use, in proportion to a reasonable benefit / risk ratio, and, where possible, in the zwitterionic form of the subject matter currently disclosed.

[1154] Therefore, the term "salt" refers to the relatively non-toxic inorganic and organic acid addition salts of currently disclosed compounds. These salts can be prepared during the final separation and purification of the compound, or by reacting the purified compound, in its free base form, with a suitable organic or inorganic acid and separating the salt thus formed. Basic compounds are capable of forming a wide variety of salts with various inorganic and organic acids. Acid addition salts of basic compounds are prepared by contacting the free base form with a sufficient amount of the desired acid in a conventional manner to produce the salt. The free base form can be regenerated by contacting the salt form with a base in a conventional manner and separating the free base. The free base form may differ from its corresponding salt form in certain physical properties, such as solubility in polar solvents. Pharmaceutically acceptable base addition salts can be formed from metals or amines such as alkali metal and alkaline earth metal hydroxides or organic amines. Examples of metals used as cations include, but are not limited to, sodium, potassium, magnesium, calcium, etc. Examples of suitable amines include, but are not limited to, N,N'-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, ethylenediamine, N-methylglucosamine, and procaine. Base addition salts of acidic compounds are prepared by contacting the free acid form with a sufficient amount of the desired base in a conventional manner to produce the salt. The free acid form can be regenerated by contacting the salt form with an acid in a conventional manner and then separating the free acid. The free acid form and its corresponding salt form may differ in some physical properties, such as solubility in polar solvents.

[1155] Salts can be prepared from inorganic acids such as sulfates, pyrosulfates, bisulfates, sulfites, nitrates, phosphates, monohydrogen phosphates, dihydrogen phosphates, metaphosphates, pyrophosphates, chlorides, bromides, and iodides, including hydrochloric acid, nitric acid, phosphoric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, and phosphoric acid. Representative salts include hydrobromide, hydrochloride, sulfate, bisulfate, nitrate, acetate, oxalate, valerate, oleate, palmitate, stearate, laurate, borate, benzoate, lactate, phosphate, toluenesulfonate, citrate, maleate, fumarate, succinate, tartrate, naphthylmethanesulfonate, gluconate, lactobionate, laurylsulfonate, and hydroxyethylsulfonate. Salts can also be prepared from organic acids, such as aliphatic monocarboxylic acids and dicarboxylic acids, phenyl-substituted alkanes, hydroxyalkanes, alkanedioic acids, aromatic acids, and aliphatic and aromatic sulfonic acids. Representative salts include acetates, propionates, caprylates, isobutyrates, oxalates, malonates, succinates, caprylates, sebacic acid salts, fumarates, maleates, mandelates, benzoates, chlorobenzoates, methylbenzoates, dinitrobenzoates, phthalates, benzenesulfonates, toluenesulfonates, phenylacetates, citrates, lactates, maleates, tartrates, and methanesulfonates. Pharmaceutically acceptable salts may include cations based on alkali metals and alkaline earth metals such as sodium, lithium, potassium, calcium, and magnesium, as well as non-toxic ammonium, quaternary ammonium, and amine cations, including but not limited to ammonium, tetramethylammonium, tetraethylammonium, methylamine, dimethylamine, trimethylamine, triethylamine, and ethylamine. Salts of amino acids are also included, such as arginine salts, gluconates, and galacturonic acids. See, for example, Berge et al., J. Pharm. Sci., 1977, 66, 1-19, which are incorporated herein by reference.

[1156] Preferably, sterile injectable suspensions are formulated using suitable carriers, dispersants or wetting agents and suspending agents according to techniques known in the art. Sterile injectable formulations can also be sterile injectable solutions or suspensions in non-toxic, parenteral diluents or solvents. Acceptable media and solvents include water, Ringer's solution, and isotonic sodium chloride solution. Additionally, sterile, non-volatile oils, fatty esters, or polyols are typically used as solvents or suspension media. Furthermore, parenteral administration may involve the use of slow-release or sustained-release systems to maintain a constant dose level.

[1157] The parenteral formulations according to this disclosure include sterile aqueous or non-aqueous solutions, suspensions, or emulsions. Examples of non-aqueous solvents or media include propylene glycol, polyethylene glycol, vegetable oils (such as olive oil and corn oil), gelatin, and injectable organic esters such as ethyl oleate. Such dosage forms may also contain adjuvants such as preservatives, wetting agents, emulsifiers, and dispersants. They can be sterilized, for example, by filtration through a bacteria retaining filter, by introducing a sterilizing agent into the composition, by irradiating the composition, or by heating the composition. They can also be manufactured using sterile water or some other sterile injectable media just before use.

[1158] Sterile injectable solutions are prepared by introducing a desired amount of one or more of the disclosed compounds, along with various other ingredients listed above, into a suitable solvent and then filtering and sterilizing. Typically, dispersions are prepared by introducing various sterilized active ingredients into a sterile medium containing a base dispersion medium and desired other ingredients from those listed above. In the case of sterile powders used to prepare sterile injectable solutions, preferred methods of preparation are vacuum drying and freeze-drying techniques, which produce powders of the active ingredient plus any other desired ingredients from their previously sterile filtered solutions. Thus, for example, a parenteral composition suitable for injection is prepared by stirring 10% by volume of propylene glycol and water with 1.5% by weight of the active ingredient. The solution is isotonicized with sodium chloride and sterilized.

[1159] Formulations suitable for rectal administration are typically available as unit-dose suppositories. These suppositories are prepared by mixing the disclosed active compound with one or more conventional solid carriers, such as cocoa butter, and then molding the resulting mixture.

[1160] Formulations suitable for topical application to the skin are preferably in the form of ointments, creams, lotions, pastes, gels, sprays, aerosols, or oils. Carriers that can be used include petrolatum, lanolin, polyethylene glycol, alcohols, transdermal penetration enhancers, and combinations of two or more of these.

[1161] Formulations suitable for transdermal application may be in the form of discrete patches adapted to maintain close contact with the recipient's epidermis for extended periods. Formulations suitable for transdermal application may also be delivered via iontophoresis (see, for example, Pharmaceutical Research 3(6):318(1986)) and are typically in the form of an optional buffered aqueous solution of the active compound. In some embodiments, microneedle patches or devices are provided to deliver drugs through or into biological tissues, particularly the skin. Microneedle patches or devices allow for the delivery of drugs across or into the skin or other tissue barriers at clinically relevant rates with minimal or no damage, pain, or irritation to the tissue.

[1162] Suitable formulations for lung delivery can be delivered via a wide range of passively driven and actively powered single / multi-dose dry powder inhalers (DPIs). The most commonly used devices for respiratory delivery include nebulizers, metered-dose inhalers, and dry powder inhalers. Several types of nebulizers are available, including jet nebulizers, ultrasonic nebulizers, and vibrating screen nebulizers. The selection of a suitable lung delivery device depends on parameters such as the nature and formulation of the drug, the site of action, and the pathophysiology of the lungs.

[1269] VIII. Examples

[1270] Example 1

[1271] General method:

[1272] For convenience, the compounds of the present invention having a stereocenter are drawn as racemic. Those skilled in the art will recognize that pure enantiomers can be prepared by methods known in the art. Examples of methods for obtaining optically active materials include at least the following.

[1273] i) Physical separation of crystals – a technique for manually separating macroscopic crystals of individual enantiomers. This technique can be used if individual enantiomers exist, i.e., the material is conglomerate and the crystals are visually distinct;

[1274] ii) Simultaneous crystallization—a technique for separately crystallizing individual enantiomers from a solution of a racemic compound, which is only possible when the latter is a solid aggregate;

[1275] iii) Enzymatic resolution – a technique for partially or completely separating racemic compounds by using the different reaction rates of enantiomers with enzymes;

[1276] iv) Enzymatic asymmetric synthesis – a synthetic technique in which at least one step of the synthesis uses an enzymatic reaction to obtain enantiomerically pure desired enantiomer or an enriched synthetic precursor of desired enantiomer.

[1277] v) Chemical asymmetric synthesis – a synthetic technique in which the desired enantiomers are synthesized from achiral precursors under conditions that produce asymmetry (i.e., chirality) in the product, which can be achieved using chiral catalysts or chiral auxiliaries.

[1278] vi) Diastereomer Separation – A technique that converts a single enantiomer into a diastereomer by reacting a racemic compound with an enantiomer-pure reagent (chiral auxiliary agent). The resulting diastereomers are then separated by chromatography or crystallization based on their now more pronounced structural differences, followed by removal of the chiral auxiliary agent to obtain the desired enantiomer;

[1279] vii) Primary and secondary asymmetric transformations—the diastereomers from the racemic product reach equilibrium and produce a quantitative advantage in a solution of the diastereomer from the desired enantiomer, or the preferential crystallization of the diastereomer from the desired enantiomer perturbs this equilibrium so that, in principle, all materials are eventually converted from the desired enantiomer to the crystalline diastereomer. The desired enantiomer is then released from the diastereomer.

[1280] viii) Kinetic resolution – This technique refers to the partial or complete resolution of racemic compounds (or further resolution of partially resolved compounds) by means of different reaction rates of enantiomers with chiral non-racemic reagents or catalysts under kinetic conditions.

[1281] ix) Enantiospecific synthesis from non-racemic precursors—synthetic techniques in which the desired enantiomers are obtained from achiral starting materials and in which the stereochemical integrity is not compromised or is only minimally compromised during synthesis;

[1282] x) Chiral liquid chromatography—a technique for separating enantiomers of racemic compounds in a liquid mobile phase by means of their different interactions with the stationary phase (including via chiral HPLC). The stationary phase may be made of a chiral material, or the mobile phase may contain other chiral materials to stimulate different interactions;

[1283] xi) Chiral gas chromatography – a technique for volatilizing racemic compounds and separating enantiomers by means of their different interactions with a column containing a fixed non-racemic chiral adsorbent phase in a gaseous mobile phase.

[1284] xii) Chiral solvent extraction – a technique for separating enantiomers by means of the preferential dissolution of an enantiomer in a specific chiral solvent;

[1285] xiii) Transchiral membrane transport—a technique that places a racemic compound in contact with a membrane barrier. This barrier typically separates two miscible fluids, one of which contains the racemic compound, and driving forces such as concentration or pressure differential cause preferential transport across the membrane barrier. Separation occurs due to the non-racemic chiral nature of the membrane, which allows only one enantiomer of the racemic compound to pass through.

[1286] Chiral chromatography, including simulated moving bed chromatography, is used in some implementations. A wide variety of commercially available chiral stationary phases are available.
