[0234] Specific implementation methods Hereinafter, the embodiments of the present invention will be described with reference to certain specific examples, but those skilled in the art can easily grasp other advantages and effects of the present invention from the contents disclosed in this specification.

[0235] Definition of Terms In this application, the term "NSAID" generally refers to "nonsteroidal anti-inflammatory drugs". The term "nonsteroidal" is used to distinguish these drugs from steroids, which, among other actions, include arachidonic acid blocking action (eicosanoid-depressing), anti-inflammatory action, etc. As analgesics, NSAIDs are characterized by their non-narcotic nature. NSAIDs include aspirin, ibuprofen, and naproxen, etc. Most NSAIDs are used as non-selective inhibitors of the enzyme cyclooxygenase, inhibiting the isoenzymes cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2). Cyclooxygenase catalyzes the production of prostaglandins and thromboxanes from arachidonic acid (itself derived from the phospholipid bilayer of cells via phospholipase A2).

[0236] In this application, the term "NO-NSAID compound" generally refers to an NSAID derivative that releases nitric oxide (NO). For example, the NO-NSAID compound may include a nitrooxylated derivative of the NSAID.

[0237] In this application, the term "spacer group" generally refers to a group that separates one compound or a portion thereof from another compound or a portion thereof. For example, the spacer group may be a chemical bond, group, or linker that connects one compound or a portion thereof to another compound or a portion thereof.

[0238] In this application, the term "cyclooxygenase (COX) inhibiting moiety" generally refers to a molecule or portion thereof that is capable of decreasing the activity and / or function of cyclooxygenase in vivo and / or in vitro.

[0239] In this application, the term "cyclooxygenase (COX)", also known as prostaglandin-endoperoxide synthase (PTGS), generally refers to an enzyme (e.g., a family of isozymes, EC 1.14.99.1) capable of forming prostaglandins, such as thromboxane and prostacyclinic acid, from arachidonic acid. It is a member of the animal-type heme peroxidase family and is also known as prostaglandin G / H synthase. The specific reaction catalyzed by the COX is the conversion of arachidonic acid to prostaglandin H2 via a short-lived prostaglandin G2 intermediate. The COX may include COX-1 and COX-2. Among them, those with specificity for the COX-2 isozyme are called COX-2 selective inhibitors. The molecular weights of COX-1 and COX-2 are similar, about 70 kDa and 72 kDa, respectively, and the amino acid sequence homology is 65%, and the catalytic site is almost the same. Both proteins have three domains: an N-terminal EGF-like domain, a small four-spiral membrane anchor, and a core heme peroxidase catalytic domain. Both form dimers. In them, the isoleucine at position 523 in COX-1 is replaced by valine in COX-2. The small Val523 residue in COX-2 allows access to a hydrophobic side pocket of the enzyme (Ile523 spatial obstruction). Molecules that bind to this alternative site can be considered as selective inhibitors of COX-2.

[0240] In this application, the term "VEGFR" generally refers to Vascular Endothelial Growth Factor Receptor, which belongs to the receptor tyrosine kinases (RTKs) family. It is reported to include three main subtypes, which are VEGFR1, VEGFR2 and VEGFR3. Among them, VEGFR1 and VEGFR2 are mainly distributed on the surface of tumor vascular endothelium and mediate tumor angiogenesis, and VEGFR3 is mainly distributed on the surface of lymphatic endothelium and mediate tumor lymphangiogenesis. VEGFR2 is reported to be the main VEGF signaling receptor in angiogenesis and mitosis. The VEGF family includes VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E and placental growth factor (PGF). It is reported that VEGF-A can regulate almost all cellular responses to VEGF by binding to VEGFR-1 and VEGFR-2. Activation of VEGFR-2 in endothelial cells leads to cell proliferation, migration, increased survival and increased vascular permeability (see Waldner, Maximilian J. et al., The Journal of Experimental Medicine 207.13, 2010). Increased expression of VEGFR or its kinase activity is associated with a range of human cancers.

[0241] In this application, the term "VEGF" generally refers to vascular endothelial growth factor (VEGF), which has been reported to be a key endothelial-specific growth factor required for pathological angiogenic signaling pathways; inhibition of the VEGF receptor tyrosine kinase signaling pathway has been reported to block neovascularization in tumor growth and cause the stasis or regression of angiogenic tumors (see Gerald McMahon, The Oncologist 2000, 5:3-10).

[0242] In this application, the term "VEGFR inhibitor" generally refers to any substance or drug known or that may be discovered in the art that can cause a decrease in the expression, level, or activity of VEGFR, and includes any substance that, when administered to a subject, results in inhibition of biological activity associated with VEGFR activity in the subject, including inhibition of downstream biological effects resulting from binding of VEGFR to its natural ligand. In an embodiment, the VEGFR inhibitor includes any reagent that can inhibit either VEGFR activity or its downstream biological effects during cancer treatment. For example, the VEGFR inhibitor is used to treat tumors. For example, the VEGFR inhibitor can directly inhibit one or more functions of VEGFR. For example, the VEGFR inhibitor can bind to a nucleic acid sequence that encodes VEGFR. For example, the VEGFR inhibitor can reduce the transcription level of VEGFR protein.

[0243] In this application, the term "VEGF inhibitor" generally refers to any substance or reagent known in the art or discovered in the future, including any substance that, when administered to a subject, causes inhibition of biological activity related to VEGF activity in the subject, and can cause a decrease in the expression, number, or activity of VEGF. In some embodiments, VEGF inhibitors include any reagent that can block VEGF activity or its downstream biological action. In some embodiments, VEGF inhibitors include any reagent that can block VEGF activity or its downstream biological action in the course of cancer treatment. For example, the VEGF inhibitor is used to treat tumors. For example, the VEGF inhibitor can directly inhibit one or more functions of VEGF. For example, the VEGF inhibitor can bind to a nucleic acid sequence that codes for VEGF. For example, the VEGF inhibitor can reduce the transcription level of VEGF protein.

[0244] In the present application, methods for detecting and / or assessing the level at which the VEGF and / or VEGFR are inhibited, whether in vivo or in vitro, are common in the art and may also be used to identify, standardize, screen and / or assess the VEGF inhibitors and / or VEGFR inhibitors described in the present application.

[0245] In this application, the term "tumor" generally refers to a neoplasm formed by the proliferation of local tissue cells under the action of various carcinogenic factors, most of which are space-occupying mass-like protrusions, and are also called pathological growths. According to the cellular characteristics of the neoplasm and the degree of harm to the organism, tumors are further divided into benign tumors and malignant tumors, and cancer is a general term for malignant tumors. The tumor is selected from the group consisting of epithelial malignant tumors (cancer of epithelial origin), lung cancer (e.g., non-small cell lung cancer), breast cancer, skin cancer, bladder cancer, colon cancer, intestinal cancer, prostate cancer, pancreatic cancer, uterine cancer, cervical cancer, ovarian cancer, esophageal cancer, head and neck cancer, gastric cancer and laryngeal cancer. For example, the tumor can be liver cancer, kidney cancer, colorectal cancer, gastric cancer, esophageal cancer or thyroid cancer.

[0246] For example, the VEGFR inhibitor may include a small molecule VEGFR inhibitor, a protein polymer that specifically binds to VEGFR, an RNAi that inhibits expression of a VEGFR protein, and / or an antisense oligonucleotide that inhibits expression of a VEGFR protein.

[0247] In the present application, the term "small molecule VEGFR inhibitor" may include small molecule VEGFR inhibitors that bind reversibly or irreversibly to VEGFR, or small molecule VEGFR inhibitors that specifically bind to mutant VEGFR. For example, the small molecule VEGFR inhibitors include regorafenib, ponatinib, cabozantinib, lenvatinib, sorafenib, apatinib, axitinib, nintedanib, vandetanib, sunitinib, midostaurin, tivozanib, fruquintinib, cediranib, brivanib, donafenib, surufatinib, anlotinib, famitinib, tesevatinib ( Tesevatinib, Vorolanib, Motesanib, Linifanib, Semaxanib, Dovitinib, Orantinib, Vatalanib, Telatinib, Glesatinib, Lucitanib, Ilorasertib, Revastinib Rebastinib, Golvatinib, Foretinib, Ningetinib, Tafetinib, Altiratinib, TAS-115, Chiauranib, Henatinib, 4SC-203, AAL-993, ACTB-1003, AEE-788, AMG-628, Arenofufagin, BAW2881, BIBF-1202, BMS-690514, BMS-794833, CEP-11981, CEP-5214, CP-547632, CYC116, DW532, ENMD-2076, FIIN-1, GFB-204, BFH-772, BMS599626, BMS690514, PP 121, MGCD 265 analog, AC480, Ki 8751, KRN 633, WHI-P 154, TAK593, JI 101, AZD-2932, SCR-1481B1, isoliquiritigenin, JNJ-26483327, KI-20227, LY2457546, ODM-203, OSI-930, PF-00337210, CGP41231, R1530, RAF265, SAR131675, semaxinib, SIM010603, SKLB1002, SKLB610, SU5205, SU11652, SU14813, SU-1498, SU-4312, SU5402, T-1840383, Tanshinone IIA, TAS-115, TG 100572, TG 100801, TG100572 HCl, Toceranib, Tyrosine Phosphorylation Inhibitor A9, Tesevatinib, XL-844, XL999, ZD4190 HCl, ZM-306416, ZM323881 HCl, ABT-510, NVP-ACC789, ADT-OH, BMS-645737, EG 00229, XL-820, SGI-7079, Endostatin and / or Dihydroquercetin.

[0248] In this application, the term "specifically binds" generally means that in a complex mixture, the VEGFR inhibitor specifically recognizes and binds to a VEGFR, but does not essentially recognize or bind to other components of the complex mixture. For example, the inhibitor may have an affinity for a VEGFR that is at least 2-fold (e.g., at least 2-fold, 3-fold, 4-fold, 5-fold, 6-fold, 7-fold, 8-fold, 9-fold, 10-fold, or more) greater than its affinity for other non-specific binding components. In one embodiment, the VEGFR inhibitor has an affinity of at least 10-fold, 10-fold, 10-fold, 10-fold, or more. -6 The following equilibrium dissociation constant values ​​(e.g., 10 -7 M or less, 10 -8 M or less, 10 -9 M or less, 10 -10 M or less, or may be less than M.

[0249] In the present application, the protein polymer that specifically binds to VEGFR may be an antibody, an antibody mutant, a fusion protein, a derivative, or a fragment thereof that is directed against VEGFR, such as an antibody or an antigen-binding fragment thereof that specifically binds to VEGFR.

[0250] In the present application, the antibody generally refers to a polypeptide molecule capable of specifically recognizing and / or neutralizing a specific antigen. For example, an antibody may include any molecule that is composed of an immunoglobulin consisting of at least two heavy (H) chains and two light (L) chains linked together by disulfide bonds, and that includes an antigen-binding portion thereof. The term "antibody" includes monoclonal antibodies, antibody fragments, or antibody derivatives, including, but not limited to, human antibodies (fully human antibodies), humanized antibodies, chimeric antibodies, single-chain antibodies (e.g., scFv), and antigen-binding antibody fragments (e.g., Fab, Fab', and ((Fab)2 fragments)). Here, the chimeric antibody may be an antibody in which a portion of the heavy or light chain amino acid sequence is homologous to the corresponding amino acid sequence of an antibody of a certain species or belongs to a certain class, and the remaining region of the chain is homologous to the corresponding sequence of another species. Here, the humanized antibody may be a chimeric antibody that contains fewer sequences derived from non-human immunoglobulins, thereby fully maintaining the antigen-binding affinity and specificity of the antibody and thereby reducing the immunogenicity of the xenogeneic antibody when introduced into a human. Here, the fully human antibody is an antibody produced by a human or human immune cells, or an antibody that consists of an amino acid sequence corresponding to an antibody derived from a non-human source, such as a genetically modified non-human animal using a human antibody library, or other sequence that codes for an antibody of human origin.

[0251] In the present application, the antigen-binding fragment antibody is one or more fragments that perform a specific antigen-binding function. The antigen-binding function of the antibody is achieved by a full-length antibody fragment. The antigen-binding function of the antibody is achieved by a heavy chain consisting of a fragment of Fv, ScFv, dsFv, Fab, Fab', or F(ab')2, or a light chain consisting of a fragment of Fv, ScFv, dsFv, Fab, Fab', or F(ab')2. (1) a Fab fragment, i.e., a monovalent fragment consisting of the VL, VH, CL and CH domains; (2) an F(ab')2 fragment, which comprises a bivalent fragment in which two Fab fragments are disulfide-linked at the hinge region; (3) an Fd fragment consisting of the VH and CH domains; (4) an Fv fragment consisting of the VL and VH domains of a single-chain antibody; (5) a dAb fragment consisting of a VH domain (Ward et al, (1989) Nature 341:544-546); (6) an isolated complementarity determining region (CDR); (7) a combination of two or more isolated CDRs, optionally joined by a junction; (8) a camelized single domain antibody, which comprises two variable heavy domains and no light chain; and (9) a nanobody, which comprises a variable heavy domain, CH2 and CH3. It may also include a monovalent single chain molecule Fv (scFv) formed by pairing VL and VH (see Bird et al (1988) Science 242:423-426; and Huston et al (1988) Proc. Natl. Acad. Sci. 85:5879-5883). The "antigen-binding moiety" includes an immunoglobulin fusion protein, which contains a binding domain selected from: (1) a binding domain polypeptide fused to an immunoglobulin hinge region polypeptide; (2) a constant CH2 domain of an immunoglobulin heavy chain fused to the hinge region; and (3) a constant CH3 domain of an immunoglobulin heavy chain fused to the constant CH2 domain.

[0252] For example, the protein macromolecule that specifically binds to VEGFR is ramucirumab, an antigen-binding fragment thereof, or a functional variant thereof.

[0253] In this application, the term "VEGF capture agent" generally refers to an agent that can bind and capture VEGF. For example, the VEGF capture agent is selected from the group consisting of bevacizumab and aflibercept.

[0254] In the present application, the term "VEGF expression-reducing agent" generally refers to a substance that can directly or indirectly reduce VEGF expression in a subject. For example, the VEGF expression-reducing agent is selected from the following group: Temsirolimus and Thalidomide.

[0255] In this application, the term "RNAi" generally refers to RNA interference, which generally refers to exogenous or endogenous double-stranded RNA molecules or small RNAs that target and specifically degrade mRNA, thereby inhibiting the expression or translation of a target gene. Generally, RNAi is composed of two types of small RNAs, microRNA (miRNA) and small interfering RNA (siRNA), which can bind to other mRNA molecules to increase or decrease their activity, for example, by inhibiting the translation of mRNA into protein. In eukaryotes, the RNAi pathway cleaves long double-stranded RNA (dsRNA) into siRNA double-stranded fragments of about 20-23 nucleotides by RNase III enzymes (e.g., Dicer, DCL, Drosha). Each siRNA is divided into two single-stranded RNAs (ssRNAs), a passenger strand and a guide strand. The passenger strand is degraded, while the guide strand is incorporated into the RNA-induced silencing complex (RISC). If the guide strand is complementary to the mRNA molecule, the RISC cleaves the mRNA molecule, degrading it.

[0256] In the present application, the RNAi that inhibits the expression of a VEGFR protein may target an mRNA encoding a VEGFR, thereby specifically degrading the mRNA and inhibiting the expression or translation of the VEGFR. In the present application, the RNAi that inhibits the expression of a VEGF protein may target an mRNA encoding a VEGF, thereby specifically degrading the mRNA and inhibiting the expression or translation of the VEGF.

[0257] In this application, the term "oligonucleotide" generally refers to an oligomer or polymer of ribonucleic acid (RNA) or deoxyribonucleic acid (DNA), or any analog or structurally modified nucleic acid thereof. Such oligonucleotides include oligonucleotides consisting of naturally occurring nucleobases, sugars and covalent internucleoside (backbone) linkages, as well as non-naturally occurring oligonucleotides having similar functions. Modified or substituted oligonucleotides are generally preferred over natural forms due to, for example, enhanced cellular uptake, improved affinity for target nucleic acids, and improved stability in the presence of nucleases.

[0258] In this application, the term "antisense oligonucleotide" generally refers to a single-stranded oligonucleotide having a nucleobase sequence that allows at least partial hybridization with a corresponding region or fragment of a target nucleic acid. In this application, the antisense oligonucleotide contains about 8 to about 50 bases.

[0259] In the present application, the VEGFR inhibitor may inhibit VEGFR1, VEGFR2 and / or VEGFR3. For example, the VEGFR inhibitor may inhibit one, two or three of VEGFR1, VEGFR2 and VEGFR3.

[0266] In this application, the term "hand-foot syndrome" is also referred to as Hand Foot Syndrome (HFS), Palmar Plantar Erythrodysesthesia (PPE), or Hand-foot Skin Reaction (HFSR). Hand-foot skin reaction (HFSR) was first reported in 1984 by Jacob Lokich and Cery Moor of the New England Deaconess Hospital, Harvard Medical School. Typical clinical symptoms are progressive, with the main clinical symptoms being heat, pain, and erythematous swelling of the fingers (toes), which progresses to exfoliation, ulceration, and severe pain in severe cases. Major pathological symptoms of HFS include, for example, vacuolar degeneration of basal keratinocytes, perivascular lymphocytic infiltration of the skin, apoptosis of keratinocytes, and skin edema. For example, HFS may include numbness in the palms and soles of the feet, and erythema of the limbs due to chemotherapy. Tumor-bearing patients may develop corresponding symptoms during the course of chemotherapy or molecular targeted therapy (such as VEGFR and / or VEGF inhibitors).

[0267] There are various grading methods for hand-foot syndrome (HFS), but the National Cancer Institute (NCI) grading criteria is the most commonly used, which classifies HFS into three grades: Grade 1 is mild skin changes or dermatitis with sensory abnormalities (e.g., loss of fingerprints, pigmentation, erythema, desquamation, paresthesia, hyposthesia, numbness of the skin, etc.) but does not interfere with daily life; Grade 2 is skin changes similar to Grade 1, accompanied by pain and mild interference with daily life, but the skin surface is intact; Grade 3 is ulcerative dermatitis or skin changes with severe pain that significantly affects daily life and is accompanied by obvious tissue destruction (scaling, blisters, bleeding, edema, etc.).

[0268] The World Health Organization (WHO) also rates HFS in four grades: Grade 1 is numbness, abnormal sensations, or tingling in the hands and feet; Grade 2 is discomfort when holding or walking, painless swelling or erythema; Grade 3 is painful erythema or edema of the palms or soles, and erythema and swelling around the nails; and Grade 4 is peeling of the skin, ulcers, herpes, and severe pain.

[0273] In this application, the term "nasopharyngitis" generally refers to an inflammatory response of the mucosa, submucosa, and lymphatic tissue of the nasopharynx, and is classified as acute nasopharyngitis or chronic nasopharyngitis. Symptoms include, but are not limited to, dryness or discomfort in the nasopharynx, thick secretions that are difficult to cough up, and nausea, and in severe cases, local and systemic symptoms such as hoarseness, sore throat, headache, dizziness, fatigue, indigestion, and low-grade fever. Examination of the nasopharynx reveals chronic congestion, hyperplasia, and hypertrophy of the mucosa, and may be covered with secretions or dry crusts.

[0274] In this application, the term "cheilitis" generally refers to an inflammatory disease or condition that occurs in the lips. For example, it includes inflammation of the perioral skin, vermilion, and / or labial mucosa. Depending on the course of the disease, it is divided into acute cheilitis and chronic cheilitis, depending on the characteristics of the clinical symptoms, it is divided into erosive cheilitis, atopic cheilitis, and exfoliative cheilitis, depending on the etiology and pathology, it is divided into chronic nonspecific cheilitis, glandular cheilitis, benign lymphoproliferative cheilitis, granulomatous cheilitis, Melkersson-Rosenthal syndrome, actinic cheilitis, allergic cheilitis, etc.

[0276] In this application, the term "epithelial tissue" includes one or more cell layers covering free and closed surfaces throughout the body, consisting of skin, mucus, luminal, serous and glandular cavities. All epithelial layers contain two specialized domains: an apical domain facing the mucosa (or luminal) and a basolateral domain facing the serous membrane (or deep). Thus, an important function of epithelial tissue is to provide an appropriate barrier function to separate and control the many physiological processes that occur between these two spaces. Epithelial tissue contains epithelial cells and endothelial cells.

In this application, the term "nitric oxide releasing agent" generally refers to any substance capable of donating, generating and / or releasing nitric oxide. In certain embodiments, a nitric oxide releasing agent can donate, generate and / or release nitric oxide directly. For example, a nitric oxide releasing agent can directly donate, generate and / or release nitric oxide by stimulating another substance. For example, a nitric oxide releasing agent is used as a reactant in a chemical or enzyme-catalyzed reaction that directly donates, generates and / or releases nitric oxide. In certain embodiments, a nitric oxide releasing agent can act as a catalyst for a chemical or enzyme-catalyzed reaction in which another substance is stimulated to donate, generate and / or release nitric oxide. Nitric oxide releasing agents also include nitric oxide itself.

[0278] In this application, the term "organic molecule" refers generally to compounds that contain the element carbon, and does not include oxides of carbon, carbonic acids, carbonates, cyanides, cyanides, oxycyanides, cyanates, sulfur cyanides, metal carbides, and the like.

For example, the cancer lesion is the primary site of cancer. For example, the cancer metastasis site may be a site where the same type of tumor as the primary tumor is present. For example, the cancer metastasis site occurs via lymphatic metastasis, vascular metastasis, and transplant metastasis.

[0296] In this application, the terms "a," "the," "at least one," and similar referents are to be construed to encompass both the singular and the plural. Unless otherwise indicated in this specification or clearly contradicted by context, the term "at least one" followed by one or more (e.g., "at least one of A and B") should be understood to mean one item (A or B) selected from the list, or any combination of two or more (A and B).

[0297] In this application, unless otherwise indicated, the terms "comprise," "have," and "containing" are to be construed as open-ended terms (i.e., meaning "including, but not limited to"). However, in this application, the term "comprise" should be understood to also record closed-ended language such as "consisting of," "having," "is," etc.

[0298] In this application, the term "EGFR" generally refers to the Epidermal Growth Factor Receptor, also known as ErbB1 or HER1, which is a 170 kDa transmembrane glycoprotein encoded by the c-erbB1 proto-oncogene. EGFR is a member of the human epidermal growth factor receptor (HER) family of receptor tyrosine kinases (RTKs), which includes HER2 (ErbB2), HER3 (ErbB3), and HER4 (ErbB4). EGFR signaling is triggered by ligand binding, which then initiates a signaling cascade by inducing conformational changes, homo- or heterodimerization, trans-autophosphorylation, etc. of the receptor and other ErbB family members (see Ferguson et al, Annu Rev Biophys, 37:353-73, 2008), ultimately affecting various cellular functions, such as cell proliferation and survival. Increased expression and kinase activity of EGFR has been associated with a variety of human cancers (Mendelsohn et al, Oncogene 19:6550-6565, 2000; GrUnwald et al, J Natl Cancer Inst 95:851-67, 2003; Mendelsohn et al, Semin Oncol 33:369-85, 2006). Increased EGFR expression is known to be observed in many cancers, including gliomas, breast cancer, ovarian cancer, and cervical cancer.

[0468] In some embodiments, the disease or condition is caused by administration of the anti-tumor agent, e.g., the disease or condition may appear or worsen after administration of the anti-tumor agent.

[0469] In certain embodiments, the subject is free of the disease or condition prior to administration of the anti-tumor agent.

[0470] For example, the disease or condition may include a disease or condition of epithelial tissue. For example, the epithelial tissue disease or condition may include a disease or condition associated with an endothelial cell lesion and / or a disease or condition associated with an epithelial cell lesion. For example, the epithelial cells may include skin epithelial cells, oral epithelial cells, nasal epithelial cells, gastric epithelial cells and / or intestinal epithelial cells.

[0473] The inventors of the present application have found that anti-tumor agents can damage endothelial cells and endothelial tissues, leading to diseases or illnesses in skin tissues, oral tissues, nasal tissues, and / or gastrointestinal tissues. In the onset and progression of these diseases or conditions, the disease process usually begins with damage / lesions to the endothelium and endothelial tissues, followed by lesions in the epithelium, and finally manifests in patients in the form of endothelial cell lesions associated with administration of anti-tumor agents, and / or epithelial cell lesions associated with administration of anti-tumor agents.

[0474] For example, the disease or condition may include a skin disease or condition, a 5-systemic disease or condition, and / or a gastrointestinal disease or condition.

[0475] In one embodiment, the skin disease or condition comprises alopecia, body odor, bullous dermatitis, xeroderma, eczema, erythema multiforme, erythroderma, subcutaneous lipoatrophy, changes in hair color, abnormal hair texture, hirsutism, hyperhidrosis, hyperkeratosis, hypertrophy, hypohidrosis, lipohypertrophy, nail changes, nail discoloration, nail loss, hypertrophic nail ridges, skin pain, hand-foot syndrome, photosensitivity, pruritus, purpura, acneiform rash, papules, scalp pain, skin atrophy, skin hyperpigmentation, skin hypopigmentation, skin sclerosis, skin ulcers, Stevens-Johnson syndrome, subcutaneous emphysema, telangiectasia, toxic epidermal necrolysis, rash and / or hives.

[0476] In one embodiment, the skin disease or condition is hand-foot syndrome.

[0477] In one embodiment, the present application relates to the use of the NO-NSAID compounds to prevent, alleviate and / or treat a disease or condition (e.g., hand-foot syndrome) in a subject associated with administration of the anti-tumor agent (e.g., a VEGFR inhibitor and / or a VEGF inhibitor).

[0478] In one embodiment, the present application relates to the use of the NO-NSAID to prevent, alleviate and / or treat a disease or condition (e.g., a rash) in a subject associated with administration of the anti-tumor agent (e.g., an EGFR inhibitor).

[0479] In one embodiment, the severity of the skin disease or condition is grade 1 or greater, grade 2 or greater, grade 3 or greater, grade 4 or greater, or grade 5 based on NCI-CTCAE.

[0480] In some embodiments, the subject comprises a cancer patient. In some embodiments, the area affected by the skin disease or condition is different from the area affected by the cancer.

[0481] In the present application, the disease or illness associated with the administration of an antitumor agent may have a statistically significant correlation with the antitumor agent. In an embodiment, the disease or illness associated with the administration of an antitumor agent may be caused by the antitumor agent. For example, the disease or illness associated with the administration of an antitumor agent may include a skin disease or illness, a five organs disease or illness, and / or a gastrointestinal disease or illness associated with the administration of an antitumor agent. For example, the skin disease or illness, the five organs disease or illness, and / or a gastrointestinal disease or illness associated with the administration of an antitumor agent may consist of the epithelial tissue disease or illness in the skin tissue, the five senses, and / or the gastrointestinal tract associated with the administration of an antitumor agent. In an embodiment, the disease or illness associated with the administration of an antitumor agent may include a side effect or adverse reaction caused by the administration of an antitumor agent.

[0482] In this application, the disease or illness associated with the administration of an antitumor agent may be a new indication, and the indication may be different from any one of the previous other diseases or illnesses.

For example, Freireich et al. described the correlation of dosages in animals and humans (based on milligrams per square meter of body surface). (Freireich et al., Cancer Chemother. Rep. 50, 219 (1966)). Body surface area can be estimated from the height and weight of the patient. See Scientific Tables, Geigy Pharmaceuticals, Ardsley, NY, 537 (1970).

[0504] In the methods of the present application, the anti-tumor agent may be induced by administration of an anti-tumor agent to the subject.

[0505] For example, the NO-NSAID compound may be administered prior to, concurrently with, or following administration of the anti-tumor agent to the subject. When the antitumor agent described in the present application is co-administered with the NO-NSAID compound, the NO-NSAID compound is administered at a dosage level of about 0.0001-10% (e.g., about 0.005-10%, about 0.01-10%, about 0.05-10%, about 0.1-10%, about 0.2-10%, about 0.3-10%, about 0.4-10%, about 0.5-10%, about 0.6-10%, about 0.7-10%, about 0.8-10%, about 0.9-10%, about 0.95-10%, about 1-10%, about 2-10%, about 3-10%, about 5-10%, about 6-10%, about 8-10%, or a smaller range) of the total dosage.

[0508] In the present application, the subject may already be suffering from a disease or condition associated with administration of an anti-tumor agent, or the subject may be more likely to suffer from a disease or condition associated with administration of an anti-tumor agent.

[0509] The present application provides a method comprising the steps of: 1) monitoring one or more side effects, such as skin tissue, organ system and / or gastrointestinal characteristics, in a subject to which an anti-tumor agent is administered; and 2) administering a NO-NSAID compound to the subject if said monitoring reveals that the subject is experiencing a side effect, such as a skin disease or condition, organ system disease or condition, and / or gastrointestinal disease or condition, associated with administration of the anti-tumor agent.

[0510] In the present application, the method may further include continuing to monitor the skin disease or condition, the 5 organ system disease or condition, and / or the gastrointestinal disease or condition, and optionally reducing or ceasing the anti-tumor agent. For example, the continued monitoring may refer to monitoring for at least one day, at least one week, at least ten days, at least two weeks, at least three weeks, at least one month, at least three months, or more after administration of the anti-tumor agent. For example, the reduction or ceasing is a reduction of about 5% or more, 10% or more, 20% or more, 30% or more, 40% or more, 50% or more, 60% or more, 70% or more, 80% or more, 90% or more, 95% or more, 99% or more, or 100% of the dose of the anti-tumor agent administered to the subject, compared to the dose of the anti-tumor agent in step 1) of the method.

[0512] In the present application, the subject may not be suffering from the disease or illness prior to administration of the anti-tumor agent.

[0513] In the present application, the NO-NSAID compound can be administered locally to the subject. For example, the NO-NSAID compound can be administered locally to the subject at a site that is substantially free of cancer cells. Also, for example, the NO-NSAID compound can be administered to the subject at a non-cancer site.

[0514] Without wishing to be bound by any theory, the following examples are intended merely to elucidate the NO-NSAID compounds, preparation methods, uses, etc. of the present application, and are not intended to limit the scope of the invention of the present application.

[0515] Working Example NO-NSAID Compound List In the following embodiments, the NO-NSAID compounds of the present application used are shown in Table 2-1:

[0516] [Table 2-1]

[0517] TIFF2025502545000113.tif84170

[0518] NO-NSAIDs can prevent / treat antineoplastic agent-induced hand-foot syndrome in vivo A rat animal model was constructed by orally administering the antitumor agents shown in Table 2-2 to 8-week-old female SD rats every day, and after a few days, symptoms of hand-foot syndrome appeared in the rat's feet (shown in Figure 1). Similar to humans, rats also develop symptoms of hand-foot syndrome after administration of the above antitumor agents, and the symptoms are very similar. Therefore, rats are a suitable animal model for mimicking the side effects of antitumor agents (such as hand-foot syndrome).

[0519] After acclimating the rats (approximately 200 g) for one week, they were divided into a NO-NSAID group and a control group (10 rats / group) and an oral administration test was performed. Various antitumor agents were dissolved in a mixed solution of castor oil:ethanol = 1:1, and the antitumor agent solution was diluted with PBS to the desired concentration and then orally administered (approximately 3-fold dilution with PBS solution). The oral dose was 2 mL or less per administration, and the dose was as shown in Table 2-2. After administration, an ointment containing NO-NSAID was applied to the hind legs of the rats, and a blank formulation was applied to the control group. After drug application, the rats were placed in a fixed canister and fixed for 4 hours, after which the rats were released, the drug remaining at the application site was wiped off with water, and the rats were returned to their cages. The number of oral administrations of the inhibitors was as shown in Table 2-2, and NO-NSAID was applied only once a day. Oral administration and application were repeated every day until the end of the test. 15 to 18 days after application, the number of rats that were normal or showed significantly milder hand-foot syndrome than the blank control group was counted as the number of rats that showed an inhibitory effect on hand-foot syndrome.

[0520] Table 2-2 shows the combinations of animal experiments in which each antitumor agent and NO-NSAID ointment was administered, and the corresponding experimental results (where the value in the control rate column = hand-foot syndrome model construction rate in the blank group - hand-foot syndrome model construction rate in the application group).

[0521] [Table 2-2]

[0525] TIFF2025502545000118.tif70170

[0526] From the results in Table 2-2, it can be seen that the NO-NSAID ointment is effective against antitumor agent-induced hand-foot syndrome. In addition, the results in Figure 2 show that NO-NSAID is effective against antitumor agent-induced hand-foot syndrome. After the experiment, the rat paws of different groups were collected and histological observations were performed on different groups (Figure 3). It was found that the NO-NSAID of the present application can effectively alleviate hand-foot syndrome induced by antitumor agents, improve capillaries, and alleviate phenomena such as keratinocyte necrosis, epidermal peeling, and inflammation. Furthermore, when the molar ratio of NSAID to NO in the NO-NSAID compound of the present application is about 1:1, the control rate of hand-foot syndrome associated with the administration of antitumor agents is excellent.

[0527] NO-NSAIDs prevent / treat hand-foot syndrome induced by protein macromolecular inhibitors in vivo Ramucirumab or Bevacizumab was diluted with saline to the desired concentration. After acclimating the rats (approximately 200g) for one week, they were divided into groups of 10 rats and administered by injection. The diluted ramucirumab was administered intravenously over 60 minutes, and 40mg / kg was administered once a week in combination with paclitaxel (10mg / kg). The NO-NSAID ointment was applied to the experimental group, and the blank formulation was applied to the control group in the same manner as above. The experiment was continued for 2 to 4 weeks, and the experimental phenomenon was observed.

[0528] Table 3 shows animal experiments in which each polymeric antitumor agent and NO-NSAID ointment was administered and the corresponding experimental results (wherein the value in the control rate column = hand-foot syndrome model construction rate in the blank group - hand-foot syndrome model construction rate in the application group).

[0529] [Table 3]

[0530] From the above experimental results, it can be seen that the NO-NSAID ointment of the present application has a preventive effect on hand-foot syndrome induced by polymeric antitumor agents.

[0531] NO-NSAID ointment relieves pain in antitumor drug-induced hand-foot syndrome After the experimental period of the preventive drug administration test (Examples 1-14 including the preventive part) described above, the rats' pain was analyzed, and the model for pain evaluation was rat mechanical sensitivity (von Frey); the experimental procedure is as follows: first, the rats were acclimatized in the room for 1 hour, then the rats were placed in an observation box with a metal mesh floor, and the mice were allowed to stay in the box for 20 minutes to acclimate and adapt to the experimental environment. Then, using a von Frey device, the surface of the rat's paw was stimulated with a specially designed cilia to detect the animal's mechanical sensitivity at strengths of 0.4g, 0.8g, 1.5g, 2.5g, 4g, 8g, 10g, and 20g, thereby detecting the pain of the paw (IITC Life Science, Woodland Hills, Series 2390). Rats that immediately withdrew or licked their paws after a certain pressure was applied were defined as responsive, and rats that did not withdraw their paws within 6 seconds were defined as non-responsive. The rats' motor response was considered an ambiguous response, in which case the stimulation experiment was repeated.

[0532] The results are shown in Figures 4 to 10. NO-NSAIDs have the effect of significantly alleviating the pain of antitumor agent-induced hand-foot syndrome.

[0533] NO-NSAID ointment can prevent / treat antitumor drug-induced hand-foot syndrome The rats (approximately 200 g) were allowed to acclimate for one week, and then divided into groups of 10 rats each, and an oral administration test was performed. The antitumor agent was dissolved in a mixed solution of castor oil:ethanol = 1:1, diluted to the desired concentration with PBS, and then orally administered (approximately 3-fold dilution with PBS solution). The oral dose was 2 mL or less, and the dose was as shown in Table 4. The antitumor agent was orally administered continuously every day until the rats developed hand-foot syndrome, at which point the rat treatment experiment was started. For specific experimental procedures, see the prevention test. Five to 13 days after application, rats that returned to normal or showed significant relief compared to before application were counted as rats that had effectively treated hand-foot syndrome.

[0534] Table 4 shows animal experiments in which each antitumor agent and NO-NSAID ointment was administered and the corresponding experimental results (where the value in the control rate column = model construction rate of hand-foot syndrome in the blank group - model construction rate of hand-foot syndrome in the application group).

[0535] [Table 4]

[0536] TIFF2025502545000121.tif146170

[0537] From this result, it can be seen that the NO-NSAID of the present application can treat antineoplastic agent-induced hand-foot syndrome.In addition, as shown in Figure 11, some experimental groups were evaluated for pain relief, and the results showed that the NO-NSAID ointment can treat antineoplastic agent-induced hand-foot syndrome and also provide some pain relief.

[0538] NO-NSAID ointment can prevent / treat chemotherapy-induced hand-foot syndrome in a rat model A rat model was established. Chemotherapeutic agents were orally administered daily to 6-week-old female SD rats (see Table 5 for doses and drugs administered), and hand-foot syndrome developed in the rats' paws after a few days.

[0539] SD rats (approximately 200 g) were acclimated for one week, and then divided into groups of 10 rats each, and an oral administration test was performed. The chemotherapy agent was dissolved and orally administered at the dose shown in Table 5 at 1 mL / 100 g per rat. After oral administration, the rats were fixed in a fixed canister, and the NO-NSAID ointment was applied to the feet of the rats in the application group, and the blank ointment (as a blank control) was applied to the rats in the blank group. The oral administration and application test were repeated every day until obvious hand-foot syndrome appeared in the blank group, and at that point, the number of rats whose foot skin was normal or whose symptoms were significantly alleviated compared to the blank group in which hand-foot syndrome appeared were counted as rats in which the suppressive effect on hand-foot syndrome was observed.

[0540] Table 5 shows the combinations of animal experiments in which chemotherapy agents and NO-NSAID ointments were administered and the corresponding experimental results (where the value in the control rate column = model construction rate of hand-foot syndrome in the blank group - model construction rate of hand-foot syndrome in the application group).

[0541] [Table 5]

[0542] TIFF2025502545000123.tif219170

[0543] From the above results, it can be seen that the NO-NSAID ointment of the present application has a preventive effect on hand-foot syndrome caused by chemotherapy agents, and also significantly relieves pain and inflammation (Figure 12).

[0544] Comparison of the results of compounds with different mechanisms in the prevention of antitumor drug-induced hand-foot syndrome After acclimating rats (approximately 200 g) for one week, they were divided into groups of 10 rats each, and then an oral administration test was performed. The antitumor agent (antitumor agent modeled on sorafenib) was dissolved in a mixed solution of castor oil:ethanol = 1:1, diluted to the desired concentration with PBS, and then orally administered (approximately 3-fold dilution with PBS solution). The single oral dose was 2 mL or less, and the dose was as shown in Table 6. After oral administration, ointments with different mechanisms were applied to the hind legs of the rats (nitric oxide releasing agent group, nitric oxide releasing agent and clinical drug combination group, NSAID group), and a blank formulation was applied to the control group. After drug application, the rats were placed in a fixed canister for 4 hours, and after 4 hours the rats were released, the remaining drug at the application site was wiped with water, and the rats were returned to their cages. The number of oral administrations of the inhibitor is shown in Table 6, but the inhibitor was applied only once a day to the different experimental groups. Oral administration and application procedures were repeated every day until the end of the test. 15 to 18 days after application, the number of rats that were normal or showed significantly milder hand-foot syndrome than the blank control group was counted as the number of rats that showed an inhibitory effect on hand-foot syndrome.

[0545] Table 6 shows the combinations of animal experiments in which each antitumor agent and each experimental ointment was administered, and the corresponding experimental results (wherein the value in the control rate column = hand-foot syndrome model construction rate in the blank group - hand-foot syndrome model construction rate in the application group).

[0546] [Table 6]

[0547] The above results show that in antineoplastic agent-induced hand-foot syndrome, NSAID ointments are basically ineffective or have a very low effectiveness rate, and in rats where relief was observed, the effect of alleviating symptoms was low; the results of the combined use of nitric oxide releasing agents and clinical drugs showed that when nitric oxide releasing agents were combined with the mechanisms of other clinical drugs, there was no significant improvement in the effect on hand-foot syndrome compared to nitric oxide releasing agents.

[0548] In terms of pain scores, NO-NSAIDs have a more obvious analgesic effect than NSAIDs at the same concentration, and at the same time, NO-NSAIDs have a more obvious analgesic effect than the combination of nitric oxide releasing agents + other drug mechanisms.

[0549] Effect of NO-NSAIDs on the mitigation of antitumor drug-induced growth toxicity in HUVEC cells The cultured HUVEC cells were digested and suspended, the cell number was counted, and inoculated into a 96-well plate, with 5,000 to 10,000 cells inoculated per well. Each well was divided into a blank control group, an antitumor agent group, an antitumor agent + NO-NSAID group, an antitumor agent solvent group, and a NO-NSAID control group, and each well of each group contained basal medium, and each well finally contained about 100 μL of liquid. The specific groupings are as follows: 1) Blank control group: no solution was added except for the regular medium exchange; 2) Antitumor agent group: Antitumor agent solution was added (final concentrations are shown in Tables 7-1 to 7-2, and the solvent for the antitumor agent solution was DMSO); 3) Antitumor agent + NO-NSAID group: Add antitumor agent solution and NO-NSAID solution (the final concentrations of antitumor agent and NO-NSAID are as shown in Table 7-1 to Table 7-2. According to the solubility of NO-NSAID, the solvent of NO-NSAID solution is selected as ethanol or sterile water. The slight difference in the total amount of each group is compensated by the addition of the corresponding solvent selected); 4) Antitumor agent solvent group: Add the same amount of DMSO contained in the solution corresponding to the antitumor agent in group 2); 5) NO-NSAID control group: Add the same volume and type of solvent (eg, ethanol or sterile water) as that included with the corresponding NO-NSAID in group 3).

[0550] The antitumor agent solvent group was not included in the data processing and was used only as a reference to evaluate experimental systematic errors. The NO-NSAID solvent control group was used for data correction to exclude the effect of the solvent on the results.

[0551] After culturing for 24-48 hours, the cell viability was measured using a Cell Counting Kit-8 (CCK-8) assay kit (C0037, Beyotime Biotechnology, Shanghai, China), and the proliferation toxicity of the antitumor agents and the alleviation effect of NO-NSAIDs on the proliferation toxicity were calculated. The results were statistically analyzed and plotted using GraphPad Prism 6.0 software and t-test.

[0565] From the above results and the results in Figures 14-16, it can be seen that although the antitumor agents showed a certain degree of toxicity to HUVEC cells, the addition of NO-NSAIDs increased the cell viability, indicating that NO-NSAIDs showed a significant alleviation effect on the proliferation toxicity induced by the antitumor agents.

[0571] As can be seen from the results in Table 7-2 and Figures 17-21, the same NO-NSAIDs at different concentrations could alleviate the proliferation toxicity of antitumor agents to HUVEC cells to various degrees.

[0572] NO-NSAIDs attenuate the cytotoxic effects of antitumor drugs in human immortalized epidermal cells (HaCaT), human oral epithelial keratinocytes (HOK), human small intestinal epithelial cells (FHs 74 Int), and gastric epithelial cells (GES-1) Various epithelial cells were cultured for the experiments, where: human immortalized epidermal cells (HaCaT) were used in Examples 47-51, the results of which correspond to Table 8-1; human oral mucosal epithelial keratinocytes (HOK) were used in Examples 52-56, the results of which correspond to Table 8-2; gastric epithelial cells (GES-1) were used in Examples 57-61, the results of which correspond to Table 8-3; and human small intestinal epithelial cells (FHs 74 Int) were used in Examples 62-66, the results of which correspond to Table 8-4.

[0573] The cultured cells were digested and suspended, the cell number was counted and inoculated into a 96-well plate, with 5,000 to 10,000 cells inoculated per well. Each well was divided into a blank control group, an antitumor drug group, an antitumor drug + NO-NSAID group, an antitumor drug group, and a NO-NSAID solvent control group, and each well of each group contained basal medium, and each well finally contained about 100 μL of liquid. The specific groupings are as follows: 1) Blank control group: no solution was added except for the regular medium exchange; 2) Antitumor agent group: Antitumor agent solution was added (final concentrations are shown in Tables 8-1 to 8-4, and the solvent for the antitumor agent solution was DMSO); 3) Antitumor agent + NO-NSAID group: Add antitumor agent solution and NO-NSAID solution (final concentrations of antitumor agent and NO-NSAID are as shown in Table 8-1 to Table 8-4. According to the solubility of NO-NSAID, the solvent of NO-NSAID solution is selected as ethanol or sterile water. The slight difference in the total amount of each group is compensated by the addition of the selected corresponding solvent); 4) Antitumor agent solvent group: Add the same amount of DMSO contained in the solution corresponding to the antitumor agent in group 2); 5) NO-NSAID solvent control group: Add the same volume and type of solvent (eg, ethanol or sterile water) as that included with the corresponding NO-NSAID in group 3).

[0574] The antitumor agent solvent group was not included in the data processing and was used only as a reference to evaluate experimental systematic errors. The NO-NSAID solvent control group was used for data correction to exclude the effect of the solvent on the results.

[0575] After culturing for 24-48 hours, the cell viability was measured using a Cell Counting Kit-8 (CCK-8) assay kit (C0037, Beyotime Biotechnology, Shanghai, China), and the proliferation toxicity of the antitumor agents and the alleviation effect of NO-NSAIDs on the proliferation toxicity were calculated. The results were statistically analyzed and plotted using GraphPad Prism 6.0 software and t-test.

[0576] Tables 8-1 to 8-4 list various combinations of antitumor agents and NO-NSAIDs and the corresponding experimental results (wherein the data labels in the cell viability column are the increase rates of viable cells in the corresponding antitumor agent + NO-NSAID group compared to the antitumor agent group). Figure 22 shows the experimental results of HaCaT cells, Figure 23 shows the experimental results of HOK cells, Figure 24 shows the experimental results of GES-1 cells, and Figure 25 shows the experimental results of FHs 74 Int cells. Here, the abscissa indicates different experimental groups and control groups, and the ordinate represents cell viability (the cell viability of the blank control group was set as 100%, and the cell viability of other experimental groups or the solvent control group was calculated). Here, * indicates P<0.05, which indicates a significant difference compared to the corresponding antitumor agent alone administration group; statistical testing was performed by t-test.
