[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Provisional Patent Application No. 63 / 163,428, filed March 19, 2021, the disclosure of which is incorporated herein by reference in its entirety for all purposes.
[0002] Description of electronically submitted text files The contents of the text file submitted electronically herewith are incorporated herein by reference in their entirety: Computer-readable copy of the Sequence Listing (Filename: TRAI_005_00US_SeqList_ST25.txt, Recording Date: March 17, 2021, File Size: 105 KB). [Background technology]
[0003] The immune system plays a crucial role in the pathophysiology of major diseases, including atherosclerosis, diabetes, and cancer. However, most currently developed immunotherapeutic strategies focus either on effector molecules such as cytokines or on T lymphocytes, cells from the adaptive immune system (Mulder et al. Nat. Rev. Drug Discov. 2019, 18(7), 553-566; Pardoll et al. Nat. Immunol., 2012, 13, 1129-1132). While anti-cytokine therapy can neutralize bioactive cytokines in autoimmune and autoinflammatory diseases, the most commonly used immunotherapies for cancer patients involve the application of checkpoint inhibitors. Although the innate immune system was long thought to have no memory, recent studies have shown that innate immune cells undergo metabolic and epigenetic rewiring to adjust their functional programs in a process termed "trained immunity," which is involved in exerting antitumor effects (Buffen et al., 2014, PLoS Pathog. 10, e1004485; Netea et al., J. Leukoc Biol. 2017, 102, 1323-1332).
[0004] A series of pattern recognition receptors (PRRs), including TLRs, NOD2, dectin-1, and inflammasomes, can be involved in promoting trained immunity. In addition, in vitro studies have demonstrated that BCG and several other PAMPs and DAMPs, including peptidoglycan and β-glucan, can be therapeutically utilized as trained immunity stimulators. However, the in vivo therapeutic use of molecules that regulate trained immunity has been hindered by toxicity, immune-related adverse effects, and poor bioavailability, which target relevant myeloid cells and their progenitor cells.
[0005] There is a need for therapeutic agents and compositions thereof that involve the innate immune system and modulate trained immunity to treat cancer and other diseases and conditions caused by defective trained immunity. Summary of the Invention

[0055] The compounds of the present disclosure contain one or more chiral centers and / or double bonds and therefore may exist as stereoisomers, such as geometric isomers, enantiomers, or diastereomers. As used herein, the term "stereoisomer" consists of all geometric isomers, enantiomers, or diastereomers. These compounds may be designated with the symbols "R" or "S," depending on the arrangement of substituents around the stereogenic carbon atoms. The present disclosure encompasses various stereoisomers of these compounds and mixtures thereof. Stereoisomers include enantiomers and diastereomers. Mixtures of enantiomers or diastereomers may be designated by "(±)" in nomenclature, although one of skill in the art will recognize that the structure may implicitly indicate a chiral center. In embodiments, an enantiomer or stereoisomer may be provided substantially free of the corresponding enantiomer.
[0056] In embodiments, the compound is a racemic mixture of the (S)- and (R)-isomers. In other embodiments, provided herein are mixtures of compounds wherein the individual compounds of the mixture are present predominantly in the (S)- or (R)-isomeric configuration.

[0057] Individual stereoisomers of the compounds of the present disclosure can be prepared synthetically from commercially available starting materials containing an asymmetric or stereogenic center, or by preparation of a racemic mixture followed by resolution methods well known to those skilled in the art. These resolution methods are exemplified as follows: (1) coupling of the enantiomeric mixture to a chiral auxiliary, recrystallization or chromatographic separation of the resulting diastereomeric mixture, and liberation of the optically pure product from the auxiliary; (2) salt formation utilizing an optically active resolving agent; or (3) direct separation of the mixture of optical enantiomers on a chiral chromatographic column. Stereoisomeric mixtures can also be resolved into their component stereoisomers by well-known methods, such as chiral-phase gas chromatography, chiral-phase high-performance liquid chromatography, crystallization of the compound as a chiral salt complex, or crystallization of the compound in a chiral solvent. Stereoisomers can also be obtained from stereomerically pure intermediates, reagents, and catalysts by well-known asymmetric synthetic methods.
[0058] Geometric isomers may also exist in the compounds of the present disclosure. The present disclosure encompasses various geometric isomers and mixtures thereof resulting from the arrangement of substituents around a carbon-carbon double bond or the arrangement of substituents around a carbon ring. Substituents around a carbon-carbon double bond are designated as being in the "Z" or "E" configuration, and the terms "Z" and "E" are used according to IUPAC standards. Unless otherwise specified, structures depicting double bonds include both E and Z isomers.
[0059] Substituents around a carbon-carbon double bond are sometimes referred to as "cis" or "trans," with "cis" referring to substituents on the same side of the double bond and "trans" referring to substituents on opposite sides of the double bond. The arrangement of substituents around a carbocyclic ring is designated as "cis" or "trans." The term "cis" refers to substituents on the same side of the plane of the ring and the term "trans" refers to substituents on opposite sides of the plane of the ring. A mixture of compounds in which substituents are located on both the same and opposite sides of the plane of the ring is designated "cis / trans."
[0060] The compounds disclosed herein may exist as tautomers, and both tautomeric forms are intended to be encompassed within the scope of the disclosure, even if only one tautomeric structure is shown.
[0061] As used herein, the term "isotopically enriched variant" is meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. Such compounds may be useful, for example, as analytical tools, probes in biological assays, or therapeutic agents. For example, an "isotopically enriched variant" of a compound may be an isotopic variant of a compound that differs only in the presence of one or more isotopically enriched atoms, for example, deuterium ( 2 H or D), carbon 13 ( 13 C), nitrogen 15( 15 In such isotopically substituted compounds, the following atoms, if present, may be changed, for example, hydrogen is 2 H / D, carbon 13 C, nitrogen 15 It is understood that the presence and location of such atoms may be N, and the determination of such atoms is within the skill of the art. Similarly, the present invention may include the preparation of isotopic variants with radioactive isotopes, for example, when the resulting compounds may be used in drug and / or substrate tissue distribution studies. The radioactive isotope tritium, i.e., 3 H, and carbon-14, i.e., 14 C are particularly useful for this purpose due to their ease of incorporation and rapid means of detection. Additionally, positron-emitting isotopes, e.g., 11 C. 18 F 、15O and 13 Compounds substituted with N, etc., can also be prepared and may be useful in positron emission tomography (PET) experiments to examine substrate receptor occupancy.
[0062] As used herein, the term "triglyceride" refers to an ester derived from glycerol and three fatty acids. The fatty acids may be the same or different. The notation used to describe triglycerides herein is the same as that used to describe fatty acids below. The fatty acids can be attached to the glycerol molecule in any order; for example, any fatty acid can react with any hydroxyl group on the glycerol molecule to form an ester bond. For example, in a non-limiting example, a triglyceride can contain glycerol with any combination of the following fatty acids: C18:1, C14:1, C16:1, polyunsaturated, and saturated. A triglyceride of C18:1 fatty acids simply means that the fatty acid component of the triglyceride is derived from or based on a C18:1 fatty acid. That is, a C18:1 triglyceride is an ester of glycerol and three fatty acids, each having 18 carbon atoms, each with one double bond. Similarly, a C14:1 triglyceride is an ester of glycerol and three fatty acids, each having 14 carbon atoms, each fatty acid having one double bond. Similarly, a C16:1 triglyceride is an ester of glycerol and three fatty acids, each having 16 carbon atoms, each fatty acid having one double bond. A combination of a triglyceride of C18:1 fatty acid with a C14:1 and / or C16:1 fatty acid means: (a) a C18:1 triglyceride mixed with a C14:1 triglyceride or a C16:1 triglyceride, or both; or (b) at least one of the fatty acid components of the triglyceride is derived from or based on a C18:1 fatty acid, and the other two are derived from or based on a C14:1 fatty acid and / or a C16:1 fatty acid.
[0063] The term "fatty acid" and similar terms refer to a carboxylic acid having a long aliphatic tail, either saturated or unsaturated. The terms "long aliphatic tail" and "fatty acid chain" are used interchangeably herein. Fatty acids and fatty acid chains can be esterified into phospholipids and triglycerides. As used herein, fatty acid chain lengths include C4-C30 (e.g., C6-C30), saturated or unsaturated, cis or trans, unsubstituted or substituted, branched or unbranched hydrocarbon chains (e.g., fatty acid chain lengths include C4-C30 (e.g., C6-C30), saturated or unsaturated, cis or trans, unsubstituted or substituted with 1-6 side chains). For example, in embodiments, exemplary fatty acid chains include, but are not limited to, saturated or unsaturated, cis or trans, unsubstituted or substituted hydrocarbon chains of C4, C5, C6, C7, C8, C9, C10, C11, C12, C13, C14, C15, C16, C17, C18, C19, C20, C21, C22, C23, C24, C25, C26, C27, C28, C29, or C30. Unsaturated fatty acids and fatty acid chains have one or more double bonds between carbon atoms. Saturated fatty acids and fatty acid chains do not contain double bonds. In embodiments, fatty acids are described herein by the capital letter "C" representing a carbon atom, followed by a number representing the number of carbon atoms in the fatty acid, followed by a colon and another number representing the number of double bonds in the fatty acid. For example, C16:1 refers to a 16-carbon fatty acid with one double bond, such as palmitoleic acid. The number after the colon in this notation does not indicate the position of the double bond within the fatty acid, nor does it indicate whether the hydrogen atoms attached to the carbon atoms of the double bond are cis to each other. Other examples of this notation include C18:0 (stearic acid), C18:1 (oleic acid), C18:2 (linoleic acid), C18:3 (α-linolenic acid), and C20:4 (arachidonic acid).
[0064] The term "sterol," such as, but not limited to, cholesterol, can also be utilized in the methods and compounds described herein. Sterols are animal or plant steroids containing only a hydroxyl group at C-3 and no other functional groups. Generally, sterols contain 27-30 carbon atoms and a double bond at the 5 / 6 position, and occasionally at the 7 / 8, 8 / 9, or other positions. In addition to these unsaturated species, other sterols are saturated compounds obtained by hydrogenation. One example of a suitable animal sterol is cholesterol. Typical examples of suitable phytosterols that are preferred from an application standpoint are ergosterol, campesterol, stigmasterol, brassicasterol, and preferably sitosterol or sitostanol, more specifically β-sitosterol or β-sitostanol. In addition to the phytosterols mentioned, their esters are also preferably used. The acid component of the ester may be a carboxylic acid corresponding to the formula (CA-I): RI CO-OH (CA-I); where RI CO is an aliphatic, linear or branched acyl group containing 2 to 30 carbon atoms and O and / or 1, 2, or 3 double bonds. Typical examples are acetic acid, propionic acid, hexanoic acid, butyric acid, valeric acid, caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, cyclopentanepropionic acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, conjugated linoleic acid (CLA), linolenic acid, eleostearic acid, arachidic acid, gadoleic acid, behenic acid, and erucic acid.
[0065] The term "phospholipid" refers to an amphiphilic compound consisting of two hydrophobic fatty acid "tails" and a hydrophilic "head" consisting of a phosphate group. The two components are joined by a glycerol molecule. The phosphate group can be modified with simple organic molecules such as choline, ethanolamine, or serine. Choline refers to an essential bioactive nutrient with the chemical formula R-(CH2)2-N(CH2)4. When the phosphorylated moiety is R-, it is called a phosphocholine.
[0066] As used herein, "lysolipid" includes, in non-limiting embodiments (acyl, single chain), by way of example, 1-myristoyl-2-hydroxy-sn-glycero-3-phosphocholine (MHPC), 1-palmitoyl-2-hydroxy-sn-glycero-3-phosphocholine (PHPC), and 1-stearoyl-2-hydroxy-sn-glycero-3-phosphocholine (SHPC).
[0067] The terms "apolipoprotein AI" or "apo AI" and also "apoliprotein A1" or "apoA1" refer to the protein that in humans is encoded by the APOAI gene.
[0068] Detailed Description Traditionally, the vertebrate immune system is subdivided into two parts. The first part, the innate immune system, provides an initial response to infection within minutes to hours. Its cellular components include natural killer (NK) cells, innate lymphoid cells (ILCs), and phagocytes such as monocytes, macrophages, and neutrophils. The innate immune system is triggered through the recognition of either pathogen or endogenous danger signals by pattern recognition receptors (PRRs) and acts as a rapid first line of defense. Upon detecting pathogen-associated molecular patterns (PAMPs), PRRs initiate the innate immune response, which includes antigen presentation, costimulation, and subsequent activation of the adaptive immune system through cytokine secretion. In addition, PRRs recognize damage-associated molecular patterns (DAMPs), triggering non-infectious inflammatory responses. The second phase of the response to infection involves the adaptive response, a second part of the immune system, in which T and B lymphocytes specifically recognize, proliferate, and are activated against the pathogen. These cells also build immunological memory for that specific infection. The specificity of adaptive immune system responses is mediated by immunoglobulin gene recombination at the lymphocyte level. Immunological memory results in a more rapid and quantitatively superior immune response to previously encountered antigens (compared to a primary response alone). While it was long thought that the innate immune system lacked memory, recent studies have shown that innate immune cells undergo metabolic and epigenetic rewiring to adjust their functional programs in a process termed "trained immunity," which can be considered a de facto innate immune memory.
[0069] Trained immunity is defined by a secondary, long-term hyperresponsiveness, manifested by increased cytokine secretion caused by metabolic and epigenetic rewiring of myeloid cells and their progenitor and stem cells in the bone marrow, spleen, and blood upon restimulation after a primary insult. Trained immunity (also called innate immune memory) is also defined by the long-term increased responsiveness (e.g., high cytokine production) of myeloid innate immune cells following secondary restimulation, induced by a primary insult that stimulates these cells or their progenitor and stem cells in the bone marrow and spleen, and mediated by epigenetic, metabolic, and transcriptional rewiring.
[0070] Trained immunity is regulated and maintained through the induction of training properties in progenitor cells in the bone marrow, resulting in persistent reprogramming that extends beyond the lifespan of bone marrow cells in the bloodstream. Trained immunity can be induced in cultured bone marrow cells using various "training agents," but its systemic induction requires the involvement of bone marrow progenitor cells.

These nanomaterials can be administered (e.g., intravenously) to promote trained immunity. Therapeutic induction of trained immunity may find use, for example, in overcoming immune paralysis in sepsis and infection, treating cell proliferation disorders (such as cancer), enhancing immune responses, etc.

[0182] Muramyl tripeptide phosphatidylethanolamine; N-(N-acetylmuramoyl)-L-alanyl-D-alpha-glutaminyl-N-[(7R)-4-hydroxy-4-oxido-10-oxo-7-[(1-oxohexadecyl)oxy]-3,5,9-trioxa-4-phosphapentacos-1-yl]-L-alaninamide (MTP-α-DPPE or mifamurtide): Molecular weight: 1238 Daltons. CLogP = 10.59 (uncharged) and 4.80 (negatively charged). Mifamurtide (CAS No. [83461-56-7]) was prepared according to literature procedures (e.g., DE; Wade, R. (1985) J Label Compd Radiopharm. 22 (1): 29-35. doi:10.1002 / jlcr.2580220105). The lipophilicity of this molecule is relatively low in physiological environments, with a CLogP of 4.80.
[0183] N-acetylmuramyl-L-alanyl-D-isoglutamine-6-O-stearoyl (MDP-C18[mur]) molecular weight: 759 daltons. C LogP = 5.39 (uncharged) and 1.39 (negatively charged). MDP-C18[mur] (CAS No. [60398-08-5]) was prepared according to literature procedures (e.g., Matsumoto K. et al. (1981) Infect Immun. 32(2):748-58). The lipophilicity of this molecule is low in physiological environments, with a C LogP of 1.39, which is unlikely to be sufficient to ensure reliable incorporation into HDL-derived nanoparticles.
[0184] Romurtide (CAS No. [78113-36-7]) has a molecular weight of 887 daltons. It has a lipophilicity with a CLogP of 3.90 (uncharged) and 0.61 (negatively charged) (in physiological environments, the CLogP is 0.61). This compound has low lipophilicity, with a CLogP close to 0 for charged molecules.
[0185] Murabutide (CAS number [74817-61-1]) molecular weight: 549 daltons. CLogP=-1.53 (uncharged), which is a negative CLogP value. This molecule is hydrophilic because its CLogP value is less than 0.
[0186] In embodiments, compounds of the disclosure (e.g., compounds of Formula (I), (IA), (IB), (II), (II-1), (II-2), (IIA), (IIA-1), (IIA-2) or Table 1) activate nucleotide-binding oligomerization domain-containing protein 2 (NOD2).
[0187] Anomers and open / closed structures In embodiments, molecules of the present disclosure bear an —OH substituent at the anomeric hemiacetal carbon of the muramyl sugar group, i.e., when R═H, it is understood that both anomeric isomers alpha and beta are included in the compounds of the present disclosure.
[0188] Furthermore, in those cases where R = H, it is known in the art that such molecules actually exist (in aqueous environments) in both closed and open ring isomers. Again, it is understood that both open and closed ring isomers are included in the compounds of the present disclosure.
[0189] In the non-limiting examples below, the top structures show the alpha and beta anomers, and the bottom structures show the general anomeric closed (left) and open (right) ring structures.

[0191] molecular weight The compounds of the invention preferably have a molecular weight of greater than 500 daltons, greater than 700 daltons, greater than 950 daltons, or greater than 1,200 daltons.
[0192] The compounds of the present invention preferably have a molecular weight of less than 10,000 daltons, less than 5,000 daltons, less than 2,500 daltons, or less than 1,750 daltons.
[0193] Hydrophobic In certain embodiments, the compounds of the present disclosure are essentially hydrophobic.Hydrophobicity can be estimated by calculating CLogP value.This can be performed using software programs such as Perkin Elmer's ChemDraw or ChemDraw Professional (v18).The higher the CLogP value of a compound, the more hydrophobic the compound is.
[0194] In embodiments, compounds of the present disclosure have a CLogP value of greater than about 1, greater than about 3, greater than about 5, greater than about 7, greater than about 9, or greater than about 11.
[0195] The CLogP value represents the n-octanol / water partition coefficient (Log Po / w) of a molecule and is a calculated value, as opposed to a LogP value, i.e., an experimentally determined value. Therefore, CLogP values may deviate from LogP values. Importantly, however, CLogP values provide a good comparison between the lipophilicity of molecules. CLogP values can be evaluated for molecules in either the uncharged or charged state. This is the case for molecules with ionogenic groups, such as those with carboxylic acid (-COOH) or phosphate (-OP(O)OH-O-) groups. At physiological pH (approximately 7.4), these particular groups are deprotonated and therefore charged. Also, alkyl(ated)amine groups are charged at physiological pH, in this case by protonation.
[0196] At physiological pH, the molecules of the invention have CLogP values of less than 20, or less than 15, or less than 10. Additionally, at physiological pH, the molecules of the invention have CLogP values of greater than 3, or greater than 4, or greater than 5, or greater than 5.5.

[0200] In embodiments, the nanoparticle carrier is a high-density lipoprotein (HDL)-derived nanoparticle. High-density lipoprotein (HDL)-derived nanoparticles are envisioned as delivery vehicles that, for example, improve the therapeutic index of small molecule immunomodulatory compounds and / or provide innate immune cell-specific delivery. By conferring targeting specificity to innate immune cells (such as bone marrow cells, bone marrow progenitor cells, and hematopoietic stem cells in the bone marrow, blood, and / or spleen), therapeutic agents encapsulated or incorporated into HDL-derived nanoparticles can be delivered in a concentrated and localized manner. In embodiments, the high-density lipoprotein (HDL)-derived nanoparticles comprise apoA-I or a peptidomimetic of apoA-I. In embodiments, the high-density lipoprotein (HDL)-derived nanoparticles comprise apoA-I.

Another known method includes synthesizing apoA-I by recombinant protein expression, for example, in Escherichia coli (E. coli) organisms. When expressed in bacteria, apoA-I may contain an N-terminal methionine or formylmethionine. The presence of a methionine group can be assessed by mass spectrometry (MS) methods known in the art. The location of methionine in the protein sequence can be assessed by digestion of apoA-I followed by analysis of the peptide mixture by MS, as is also known in the art.
[0202] In embodiments, purification of apoA-I, including any of its variations, can involve any method known in the art (e.g., the use of hydrophobic interaction chromatography, ion exchange columns, precipitation, etc.) The production method may or may not include the use of an affinity tag that allows for purification of the protein, such a tag needing to be removed after purification to restore the identity of human apoA-I.
[0203] In embodiments, the high density lipoprotein (HDL)-derived nanoparticles comprise ApoA-1 Milano.
[0204] Suitable apoA-I mimetic polypeptides can have the sequences shown in Table 2 (SEQ ID NOS: 256-263, and 342-346) or SEQ ID NOS: 1-341.

[0241] The production method can produce uniformly sized HDL-derived nanoparticles or a mixture of heterogeneous sized HDL-derived nanoparticles, either by not filtering or by preparing HDL-derived nanoparticles of various sizes and then recombining them in a post-production step. The larger the size of the HDL-derived nanoparticles, the more drug they can incorporate. However, larger sizes (e.g., >120 nm) may limit, hinder, or delay the diffusion of HDL-derived nanoparticles into the tissues of patients undergoing treatment. Smaller HDL-derived nanoparticles do not carry as much drug per particle, but can access bone marrow cells, bone marrow progenitor cells, and hematopoietic stem cells (biodistribution), such as bone marrow, blood, or spleen, or other local tissues affected by trained immunity.
[0242] The use of heterogeneous mixtures of nanoparticle sizes in a single dose or regimen can immediately reduce innate immune hyperresponsiveness, while providing durable and long-term relief of innate immune hyperresponsiveness that can last for days, weeks, months, and years. Nanobiologics reverse, modify, or re-regulate metabolic, epigenetic, and inflammasome pathways in hematopoietic stem cells (HSCs), common myeloid progenitor cells (CMPs), and myeloid cells, e.g., monocytes, macrophages, and other short-lived circulating cells.
[0243] In embodiments, the maximum loading capacity of HDL-derived nanoparticles can be determined by dividing the internal volume of the HDL-derived nanoparticles by the volume of the drug-loaded spheroids. Particles: Assuming 100 nm spherical particles with 2.2 nm to 3.0 nm phospholipid walls, with an inner diameter of 94 nm and a volume (large) @ 4 / 3n(r)3. The drug:stimulator (STIMULATOR) is envisioned as a 12 x 12 x 35 Å, or 1.2 x 1.2 x 3.5 nm, cylinder, and the multi-drug molecule cylinder is envisioned as a 3.5 nm diameter spheroid with a radius of 1.75 nm and a volume (small) @ 4 / 3n(r), e.g., 7 or 9. Maximum packing capacity (calculated): 3.5 nm spheroids within 100 nm particles is approximately 487 kJ.

[0296] [ka] A 20 mL PE syringe equipped with a PE frit was loaded with MTP-b resin (429 mg, approximately 0.15 mmol of MTP-b), and the resin was swollen in 12 mL of DMF for 30 min. The resin was treated twice with 2% hydrazine hydrate solution in 12 mL of DMF for 15 min. After filtration, the resin was washed with 4 x 12 mL of DMF for 1 min. A solution of CuSO4·5H2O (0.6 mg, 2.4 μmol, 1.5 mol%), imidazole-1-sulfonyl azide HCl salt (170 mg, 0.77 mmol, 5 equiv.), and N,N-diisopropylethylamine (0.34 mL, 1.9 mmol, 12 equiv.) in 12 mL of DMF was added to the resin, and the beads were stirred at room temperature for 24 h (a slight overpressure was occasionally released). After filtration, the resin was washed with DMF (5 × 12 mL) for 1 min and dichloromethane (4 × 10 mL) for 1 min. The resin was then subjected to cleavage in TFA / TIPS / HO 95:2.5:2.5 (4 mL) for 2 h. After filtration, the resin was washed with TFA (4 mL) for 5 min. The combined TFA filtrates were concentrated in vacuo (the temperature was kept as low as possible to avoid TFA ester formation). The impure compound was obtained by automated column chromatography (reverse-phase (C18); detection: λ = 200 nm) using an elution gradient of 5% to 60% MeCN in HO (both containing 0.1% TFA). This was further purified by RP-HPLC using an elution gradient of 26% to 35% MeCN in HO (both containing 0.1% TFA) to give the pure product (37.5 mg, 51 μmol, 34%) as a white fluffy solid after lyophilization. 1H-NMR (400 MHz, DMF-d7 / D2O 9:1): δ = 8.45 (t, J = 9.1 Hz, 2H), 8.26 (d, J = 7.9 Hz, 1H), 7.99 (d, J = 6.5 Hz, 1H), 7.81 (d, J = 2.8 Hz, 2H), 7.64-7.45 (m, 5H), 7.31 (d, J = 17.2 Hz, 2H), 5.82 (d, J = 6.3 Hz, 1H), 5.03 (d, J = 3.5 Hz, 1H), 4.93 (d, J = 12.4 Hz, 1H), 4.68 (d, J = 12.4 Hz, 1H), 4.63-4.46 (m, 4H), 4.19 (dd, J = 10.7, 3.6 Hz, 1H), 4.00 (dd, J = 6.8, 6.3 Hz, 1H), 3.92-3.79 (m, 3H), 3.66 (t, J = 9.0 Hz, 1H), 3.52 (t, J = 6.8 Hz, 2H), 2.53 (t, J = 7.5 Hz, 2H), 2.37 (dtd, J = 16.5, 7.9, 4.3 Hz, 1H), 2.10 (s, 3H), 2.09-1.93 (m, 2H), 1.88-1.55 (m, 5H), 1.58 (d, J = 7.1 Hz, 3H), 1.52 (d, J = 6.7 Hz, 3H). 13 C-NMR (100 MHz, DMF-d7 / D2O 9:1): δ = 174.9, 174.24, 174.17, 174.00, 173.93, 173.14, 173.06, 172.9, 172.8, 170.90, 170.8, 138.2, 128.6, 127.9, 127.8, 96.8, 80.0, 77.3, 73.7, 70.3, 68.6, 61.5, 53.6, 53.5, 53.2, 53.13, 53.10, 52.7, 52.6, 51.2, 49.4, 49.3, 32.1, 31.7, 28.5, 28.2, 23.2, 22.53, 22.48, 18.9, 17.80, 17.76.

[0298] [ka] A 25 mL round-bottom flask was charged with a solution of commercially available [(2S)-3-hydroxy-2-octadecanoyloxypropyl]octadecanoate (0.601 g, 0.96 mmol, 1.00 equiv.) in chloroform (6.5 mL, approximately 0.15 M).

[0299] 2,3,5,6-Tetrafluorophenyl stearate
[0300] [ka] Triethylamine (2.8 mL, 5 equiv.) was slowly added to a solution of stearoyl chloride (1.26 g, 4.2 mmol) and tetrafluorophenol (0.72 g, 1.04 equiv.) in DCM (10 mL), resulting in the immediate formation of a white precipitate. The heterogeneous reaction mixture was stirred for an additional 2 h, diluted with 25 mL of DCM, extracted with water (50 mL), 0.1 M HCl (2 × 50 mL), dried over MgSO4, and evaporated to dryness. The resulting solid was redissolved in 50 mL of diethyl ether and extracted again with 1 M NaHCO3 (50 mL), 0.1 M HCl (50 mL), water (50 mL), and brine (2 × 50 mL). The organic phase was dried over MgSO4 (with the addition of a small amount of activated charcoal) and evaporated to dryness.

[0301] synthetic アプローチ First Approach: The compounds of the present invention can be prepared by using the starting reactants MDP or MDP(Bn) (see above). These molecules have a functional carboxylic acid group derived from the glutamic acid (Glu) building block. The COOH group allows for conjugation to an amine-functional reactant containing a lipophilic group. Such a lipophilic group can be, for example, a C18 moiety derived from stearic acid, oleic acid, stearyl alcohol, oleyl alcohol, stearylamine, or oleylamine; or a sterol moiety, such as cholesterol. Saturated linear lipophilic moieties are preferred, as are moieties derived from cholesterol. Particularly useful building blocks are PE phospholipids such as DSPE ([1069-79-0]) or DOPE ([4004-05-1]); these molecules are already amine-functionalized. Mixed acyl PE-phospholipids can also be useful (e.g., 16:0 to 18:1 PE, or 18:0 to 18:1 PE, or 18:0 to 16:0 PE). Another useful building block is cholesterol. Yet another useful building block is a diglyceride, such as 1,2-dioctadecanoyl-sn-glycerol (18:0 DG [51063-97-9]) or 1-2-dioleoyl-sn-glycerol (18:1 DG [24529-88-2]). Mixed acyl diglycerides can also be used (e.g., 16:0 to 18:1 DG, or 18:0 to 18:1 DG, or 18:0 to 16:0 DG). PE-phospholipids and diglycerides have two lipophilic chains, and such building blocks are preferably used in this approach. This first approach is illustrated in Examples 10-19.
[0302] Second Approach: A particularly suitable alternative modular approach uses copper-catalyzed azide-alkyne cycloaddition ("click reaction") to connect MDP (or MTP) reactants to lipophilic reactants. Here, MDP, MDP(Bn), MTP, or MTP(Bn) building blocks bearing azide (-N3) or alkyne (-C≡CH) functional groups are used. Non-limiting examples of such molecules are MDP-propargyl, MDP(Bn)-propargyl, or MTP-b-N3 (see above). In a copper-catalyzed click reaction, these molecules can be coupled with alkyne- or azide-functional molecules containing lipophilic groups. The click reaction targets stable azide- or alkyne-functional intermediates that are modular and easy to prepare. This allows for easy isolation and storage of the intermediates. Furthermore, copper-catalyzed click cycloaddition reactions can be performed, and are most successful, in aqueous environments (e.g., THF / water or tBuOH / water) or aqueous biphasic liquid / liquid solvent combinations (e.g., dichloromethane / water). These reaction media favorably dissolve both hydrophilic MDP (or MTP) reactants (with or without a Bn group) and lipophilic reactants, significantly improving the ease of conjugation and reaction yield. In this click approach, the lipophilic group contained in the azide or alkyne reactant can be a C14, C16, or C18 moiety, such as stearic acid, palmitic acid, myristic acid, oleic acid, palmitoleic acid, myristoleic acid, stearyl alcohol or amine, palmityl alcohol or amine, myristyl alcohol or amine, oleyl alcohol or amine, palmitoleic alcohol or amine, or myristoleic alcohol or amine; or a sterol moiety, such as one derived from cholesterol. Saturated linear lipophilic moieties are preferred, as are moieties derived from cholesterol. Particularly useful building blocks are PE-phospholipids containing C14, C16 and / or C18 moieties, mixed acyl PE-phospholipids, diglycerides (DG) or mixed acyl diglycerides, and cholesterol.Lipophilic azide or alkyne reactants containing two lipophilic chains or containing a cholesteryl group are preferred. This second approach is illustrated in Examples 1-9.
[0303] Note that both approaches allow the introduction of an additional amino acid unit linked to the glutamic acid unit of MDP or MDP(Bn). Preferred amino acid units are those derived from L-lysine or L-alanine. Once the additional amino acid unit is attached, the MDP (muramyl dipeptide) moiety, with or without the Bn group, is converted to an MTP (muramyl tripeptide) moiety. Examples are shown in Examples 9-10, 13-15, and 17-18.

[0306] A 5 mL vial was charged with MDP-propargyl (0.011 g, 0.02 mmol, 1.00 equiv.). To this was added L-ascorbic acid (0.4 M aqueous solution, 104 μL, 41.5 μmol ascorbic acid, 2.00 equiv.). To the resulting slightly opaque solution was added a solution of 1-azidooctadecane (0.012 g, 0.04 mmol, 2.00 equiv.) in DCM (0.8 mL), followed by aqueous copper(II) sulfate pentahydrate (0.2 M, 104 μL, 20.8 μmol Cu, 1.00 equiv.). The biphasic reaction mixture was then stirred at 1400 rpm at room temperature, resulting in a pale yellow / green emulsion. After 16 h, the reaction mixture was concentrated under a stream of N2 to give the crude product as a light brown sludge. This material was dissolved in chloroform / MeOH (4:1) and impregnated onto Celite (90 mg, approximately 1:5 loading ratio).

[0309] MDP-propargyl (24.4 mg, 46 μmol) was dissolved in 0.4 M ascorbic acid (0.24 mL, 2 equiv.) and a solution of DSPE-azidoacetate (38.5 mg, 46 μmol, 1 equiv.) in dichloromethane (0.5 mL) was added. With vigorous stirring, 0.2 M CuSO 5HO (0.24 mL, 1 equiv.) was added, and the biphasic system was vigorously stirred at room temperature for 19 h. The solvent was removed in vacuo, and the greenish solid was subjected to column chromatography (flash SiO ) using an elution gradient of 20% to 50% MeOH in chloroform, ending with chloroform (45% MeOH + 5% HO). (A significant amount of the compound elutes only after the addition of HO.) This yielded an impure product, which was purified by automated column chromatography (reverse-phase (C 18 );Product:C 18-silica 1:200; detection: λ = 210 nm) using an elution gradient of 25% to 70% THF in HO, which gave the pure product (19.5 mg, 14 μmol, 31%) as a white fluffy solid after lyophilization. 1 H NMR (400 MHz, CDCl3+MeOD) δ 7.93 (s, 1H), 5.29 - 5.22 (m, 2H), 5.16 (s, 2H), 4.51 - 4.41 (m, 4H), 4.38 - 4.25 (m, 2H), 4.20 (dd, J = 12.1, 6.8 Hz, 1H), 4.05 - 3.89 (m, 4H), 3.88 - 3.77 (m, 2H), 3.77 - 3.63 (m, 6H), 3.55 - 3.42 (m, 3H), 2.34 (q, J = 7.3 Hz, 6H), 2.22 (dddd, J = 18.4, 13.5, 8.4, 5.7 Hz, 1H), 1.98 (d, J = 5.7 Hz, 4H), 1.93 (s, 0H), 1.62 (q, J = 6.4 Hz, 5H), 1.46 - 1.36 (m, 6H), 1.28 (s, 61H), 0.89 (t, J = 6.8 Hz, 6H).

[0312] MDP-propargyl (25 mg, 47 μmol) was dissolved in 0.4 M ascorbic acid (0.24 mL, 2 equiv.) and cholesterol azide acetate (26.6 mg, 57 μmol, 1.2 equiv.) in dichloromethane (0.5 mL) was added. With vigorous stirring, 0.2 M CuSO 5HO (0.24 mL, 1 equiv.) was added, and the biphasic system was stirred vigorously at room temperature for 17 h. HO / brine 1:1 (50 mL) was added, and the bluish aqueous layer was extracted with chloroform / MeOH 2:1 (5 × 20 mL). The combined organic layers were dried using NaSO, filtered, and the solvent was removed in vacuo. The resulting colorless solid was purified by repeated column chromatography (flash SiO) using an elution gradient of 6% to 20% MeOH in chloroform.

The resulting mixture was evaporated to dryness, and the resulting material was repeatedly purified by column chromatography (SiO2, CHCl3 / MeOH / HO, 70 / 30 / 5, 5:4:1, and gradient 95 / 5 / 0 to 60 / 40 / 0) to afford 6 mg (21%) of the desired compound as a white fluffy material after lyophilization from water / THF. 1 H-NMR (400 MHz, CDCl3 / CD3OD 5:) δ 5.29 (d, major isomer), 5.24 (m, 1H), 4.54 (d, minor isomer), 4.47 (m, obscured by HDO), 4.41 (dd, obscured by HDO), 4.31 (m, obscured by HDO), 4.19 (dd, 1H), 4.00-3.90 (m, mixture of isomers), 3.87-3.75 (m, mixture of isomers), 3.72 (m, 1H), 3.63 (m, 1H), 3.53-3.30 (m, obscured by CD3OD), 2.37-2.26 (m, 5H), 2.25-2.10 (m, 2H), 2.10-1.92 (m, 4H), 1.61 (m, 4H), 1.50-1.15 (br.m, 62H), 0.88 (t, 6H) ppm. 31 P-NMR (162 MHz, CDCl3 / CD3OD 5:1) δ 0.14 (br.m) ppm.13 C-NMR (101 MHz, CDCl3 / CD3OD 5:1) δ 174.63, 174.00, 173.27, 173.08, 172.92, 172.89, 171.34, 90.19, 75.19, 71.09, 70.18, 69.73, 69.65, 63.24, 62.76, 61.86, 60.84, 53.13, 52.04, 48.77, 48.19, 39.71, 33.48, 33.32, 31.29, 31.14, 28.91, 28.87, 28.76, 28.74, 28.57, 28.54, 28.37, 28.34, 26.44, 24.14, 24.10, 21.88, 21.78, 18.35, 15.98, 13.14 ppm.

[0337] [Example 13] Synthesis of MTP-b-DSG (13)
[0338] [ka] Molecular weight: 1361 daltons. CLogP=15.05.
[0339] A 20 mL PE syringe equipped with a PE frit was loaded with MTP-b on resin (0.291 g, approximately 0.11 mmol of MTP-b, 1.00 equiv.). The resin was allowed to swell in DMF (5 mL) for 30 min. The resin was then treated twice with a 2% solution of hydrazine hydrate in DMF (5 mL) for 15 min. The hydrazine solution was removed, and the resin was washed with DMF (4 × 5 mL). Next, a solution of DSG 4-nitrophenyl carbonate (0.249 g, 0.32 mmol, 3.00 equiv.) and N,N-diisopropylethylamine (0.081 g, 0.110 mL, 0.63 mmol, 6.00 equiv.) in chloroform (4 mL) was added. The beads were stirred overnight at room temperature. The bright yellow supernatant was then removed, and the resin was washed with chloroform (3 × 5 mL), MeOH (3 × 5 mL), and chloroform (2 × 5 mL). The resin was treated with TFA / TIPS / water 95 / 2.5 / 2.5 (5 mL) for 45 min. The supernatant was poured into ice-cold diethyl ether (100 mL) with stirring, resulting in the slow formation of white aggregates. This cleavage and precipitation procedure was repeated twice. The solid was collected by filtration through a disposable PE filter, yielding the crude product as a white solid. This material was impregnated onto Celite (250 mg, loading ratio 1:2.5) from a chloroform / MeOH (1:2) solution. The impregnated crude product was purified by automated column chromatography (reverse-phase (C18); product: C18-silica 1:150; detection: 200–400 nm) eluting with water / THF 60 / 40–0 / 100. The combined product fractions were lyophilized and then purified again by automated column chromatography (normal phase (silica); product:silica 1:250; detection: 200-400 nm) eluting with chloroform / MeOH 95 / 5-60 / 40.

[0342] Building block (CBz)-Ala-DPPE N-CBz-protected L-alanine (390 mg, 1.7 mmol) and N-hydroxysuccinimide (222 mg, 1.89 mmol, 1.1 equiv.) were dissolved in chloroform (6 mL) to obtain a nearly clear solution. N,N'-Diisopropylcarbodiimide (DIC; 0.32 mL, 2.0 mmol, 1.2 equiv.) was added, and the mixture was stirred at room temperature for 40 min (after 1 min, the solution became cloudy; after 25 min, H-NMR indicated complete conversion). This solution was then added to a solution containing 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE; 1.06 g, 1.5 mmol, 0.9 equiv.) and triethylamine (600 μL, 0.71 mmol, 2.5 equiv.) in chloroform (12 mL; DPPE was dissolved under reflux and triethylamine was added at low temperature). The resulting clear solution was stirred at 60°C for 1 hour (the solution remained clear and 1 H-NMR indicated complete conversion. Chloroform (360 mL) was added, and the organic layer was gently washed with 0.1 M HCl (100 mL). The organic layer was dried using Na2SO4, filtered, and the solvent removed in vacuo. Column chromatography (flash SiO2) using an elution gradient of 2% to 30% methanol in chloroform afforded the title compound, partially contaminated with triethylamine. Impure fractions were dissolved in chloroform, and the organic layer was gently washed with 0.1 M HCl. The organic layer was dried using Na2SO4, filtered, and the solvent removed in vacuo. This effectively removed triethylamine, and the pure fractions were combined to give the pure product (1.22 g, 1.4 mmol, 91%) as a colorless, waxy solid. 1H-NMR (400 MHz, DMSO-d6): δ = 8.06 (t, J = 5.7 Hz, 1H), 7.47-7.22 (m, 6H), 5.15 (dq, J = 8.3, 4.6 Hz, 1H), 5.01 (q, J = 12.6 Hz, 2H), 4.28 (dd, J = 12.0, 3.2 Hz, 1H), 4.11 (dd, J = 12.1, 7.0 Hz, 1H), 4.06-3.92 (m, 3H), 3.82 (q, J = 6.4 Hz, 2H), 3.33-3.18 (m, 2H), 2.27 (dt, J = 12.8, 5.0 Hz, 4H), 1.50 (q, J = 6.9 Hz, 4H), 1.32-1.16 (m, 51H), 0.85 (t, J = 6.7 Hz, 6H). 31 P-NMR (162 MHz, DMSO-d6): δ = -1.4.
[0343] Building block Ala-DPPE In a two-neck round-bottom flask, (CBz)-Ala-DPPE (308 mg, 0.34 mmol) and Pd / C (374 mg, 10% Pd, pre-wetted Degussa / Evonik type) were mixed in chloroform / ethanol 1:2 (36 mL). The flask was evacuated and refilled with Ar three times. A H2 balloon was attached, the flask was evacuated and refilled with H2 three times, and the mixture was stirred under positive H2 pressure at room temperature for 3 h. The solution was filtered through Celite and washed thoroughly with ethanol, chloroform / ethanol 1:1, and chloroform. The combined filtrate was evaporated to dryness, and the resulting compound was dissolved in chloroform / ethanol 2:1 (90 mL) and dried using Na2SO4. The solution was filtered through Celite and washed thoroughly with chloroform / ethanol 2:1. The filtrate was evaporated to dryness to give the product (224 mg, 0.29 mmol, 86%) as a slightly yellowish waxy solid, which contained traces of Pd. 1H-NMR (400 MHz, DMSO-d6): δ = 8.60 (br, 1H), 8.08 (br, 2H), 5.15 (br, 1H), 4.28 (d, J = 13.2 Hz, 1H), 4.12 (dd, J = 6.9 Hz, 1H), 4.00 (m, 2H), 3.88 (m, 2H), 3.80 (br, 1H), 3.09 (br, 1H), 2.35-2.23 (m, 4H), 1.50 (br, 4H), 1.41-1.14 (m, 51H), 0.85 (t, J = 6.6 Hz, 6H). 31 P-NMR (DMSO-d): δ = -1.4.
[0344] MTP(Bn)-a-DPPE(14) MDP(Bn) (20.0 mg, 34 μmol) and Ala-DPPE (26.2 mg, 34 μmol, 1.0 equiv.) were mixed in DMAc (0.3 mL) and N,N-diisopropylethylamine (24 μL, 0.14 mmol, 4 equiv.), and PyBOP (22 mg, 41 μmol, 1.2 equiv.) was added sequentially. The resulting suspension was stirred at 50 °C for 1 h, after which the mixture became nearly clear. Volatiles were removed in vacuo (oil pump, 45 °C), and the mixture was flushed once with chloroform. This was followed by column chromatography (flash SiO2) using an elution gradient of 15% to 40% methanol in chloroform, followed by automated column chromatography (reverse-phase C18; product: C18-silica 1:200; detection: λ = 200-220 nm) using an elution gradient of 30% to 80% THF in HO. This gave product 14 (8.0 mg, 6 μmol, 18%) as a white fluffy solid after lyophilization. HPLC-MS: t[product]=3.92 min; m / z=1327.80[M+H] + (SIM mode).

[0347] N-(2-aminoethyl)-cholesterol carbamate building block.
[0348] [ka] A solution of cholesterol chloroformate (0.95 g, 2.1 mmol) in 20 mL of DCM was slowly added to a solution of ethylenediamine (2 mL, 14 equiv.) in 30 mL of DCM over approximately 2 h. The reaction was allowed to proceed for an additional 30 min, after which the reaction mixture was evaporated to dryness. The resulting white material was purified by column chromatography (SiO, CHCl / MeOH / formic acid 78:20:2) to afford 720 mg (72%) of the desired compound as a white solid. 1 H NMR (400 MHz, CDCl3) δ 5.46 - 5.27 (m, 1H), 4.99 (br. s, 1H), 4.50 (br.m, 1H), 3.22 (q, J = 5.6 Hz, 2H), 2.82 (t, J = 5.9 Hz, 2H), 2.43 - 2.19 (m, 2H), 2.06 - 1.75 (m, 5H), 1.64 - 0.80 (m, 35H), 0.68 (s, 3H) ppm. 13C NMR (101 MHz, CDCl3) δ 156.41, 139.83, 122.47, 74.31, 56.68, 56.13, 50.00, 43.63, 42.30, 41.79, 39.73, 39.51, 38.57, 36.99, 36.56, 36.18, 35.79, 31.90, 31.87, 28.22, 28.17, 28.00, 24.28, 23.82, 22.81, 22.55, 21.03, 19.33, 18.71, 11.85. MALDI: m / z = 472.40 (calculated), found: 495.39 (M+Na+). A prominent peak was observed at m / z=369.37, which is attributed to the 3.4 elimination product formed in MALDI (not observed in NMR).
[0349] This building block can be coupled to N-Boc-L-alanine (CAS[15761-38-3]) via amidation; the Boc group can then be deprotected; finally, the formed amine-functional molecule can be coupled with MDP to arrive at MTP-a-chol.

[0358] Alternatively, DSPE can be attached to MDP(Bn) via amidation to arrive at the molecule MDP(Bn)-DSPE.
[0359] [Example 20] Lipophilicity studies The ClogP values of exemplary compounds of the present disclosure were evaluated using Perkin Elmer ChemDraw Professional, version 18.0.0231 (4029) software. The results show values ranging from approximately 4.15 to 18.28. At a physiological pH of approximately 7.4 (i.e., where the COOH and POH groups are charged), two molecules of the present invention have ClogP values between 4 and 5, three have values between 10 and 20, and the remaining molecule has a value between 5 and 10.
[0360] Experimentally, the lipophilicity of molecules can also be compared by running HPLC using the same elution gradient. Molecules that have a higher affinity for the hydrophobic C18 material of the column are more lipophilic and therefore have a longer retention time. The table below shows that the example molecules of the present invention (entries 1-4) have a longer retention time and are therefore more lipophilic than the comparative example molecules (entries 5 and 6).
[0361] Methods: HPLC-MS (SIM) and HPLC-ELSD were performed on a Phenomenex Kinetex 5 micrometer EVO C18 100A LC column (50 × 2.1 mm) using the same gradient from eluent A to B: A = 20 mM NH4HCO2 in H2O containing 0.1 v / v% formic acid, and B = 2-propanol / MeCN / H2O 85:15:5, also containing 20 mM NH4HCO2 and 0.1 v / v% formic acid.
[0362] [Table 3]
[0363] [Example 21] water solubility studies Compounds of the present disclosure were tested for solubility in PBS buffer and water applying low concentrations.
[0364] First, the compound was weighed into a vial and PBS buffer (137, 2.7, 10, and 1.8 mM in NaCl, KCl, NaHPO, and KHPO, respectively, pH=7.4) was added, resulting in a concentration of 0.2 mg / mL when fully dissolved. The sample was shaken, left for 1 hour, and shaken again before checking the appearance of the solution at room temperature (RT). The sample was then warmed in a 37°C water bath for 1 minute, and the appearance of the solution was checked again. The results are summarized in the table below.
[0365] None of the tested compounds spontaneously dissolved in PBS at either room temperature or 37°C. In contrast, the tested comparative compounds spontaneously dissolved under these conditions. Further treatment of the sample solutions with a heat gun did not dissolve items 4, 5, and 6, while items 2 and 3 gave cloudy solutions after cooling to room temperature.
[0366] [Table 4]
[0367] The compound was then weighed and dissolved in chloroform / methanol. The solution was allowed to dry in the vial, forming a film of material. The vial was placed under vacuum to remove traces of organic solvent. Demineralized water was added to give a compound concentration of 0.3 mM when fully dissolved (0.3 mM corresponds to 0.3 mg / mL of a compound with MW=1000 Daltons). The vial was sonicated briefly in a water bath, left overnight, and sonicated again (sonication at room temperature). The appearance of the solution at room temperature was checked to assess solubility. The results are summarized in the table below.
[0368] None of the tested compounds of the present disclosure are spontaneously soluble in water at room temperature. In contrast, the tested comparative compounds were spontaneously soluble under these conditions.
[0369] [Table 5]
[0370] Finally, Comparative Examples 1 and 2 were also tested for solubility in PBS (0.01 M, pH=7.4) and demineralized water at a level of 1 mg / mL. The same results as shown in the two tables above were found at this concentration.
[0371] Taken together, these results demonstrate that a series of compounds of the present invention are not spontaneously soluble in PBS or water at concentrations as low as 0.2 mg / mL (and higher). In contrast, the comparative materials are soluble in PBS or water, giving clear solutions at concentrations of at least 0.2 mg / mL, and even as high as 1 mg / mL.
[0372] Because the disclosed compounds have low solubility in aqueous solutions, their physicochemical properties find particular application in producing stable HDL-derived NPs. Without being bound by theory, it is believed that the disclosed compounds improve immobilization on NPs, reduce leakage, and provide products with improved stability and shelf life.
[0373] [Example 22] Degradation by enhanced oxidation test To achieve rapid degradation of the molecules by oxidation and mimic the slower oxidation phenomenon in vivo, the reference compounds MDP and MDP(Bn), as well as the Bn-substituted compounds from Example 7 (i.e., MDP(Bn)-DSPE [click] and Example 14 (i.e., MTP(Bn)-α-DPPE) were mixed with 12% hydrogen peroxide in water and heated at 80 °C for 4 h.
[0374] The resulting reaction mixture was diluted with acetonitrile and water (1:1) for MDP and MDP(Bn) test solutions, or with iPrOH, acetonitrile, and water (40:7.5:52.5) containing 0.1% formic acid and 20 mM ammonium formate for MDP(Bn)-DSPE[click] and MTP(Bn)-α-DPPE solutions. Four diluted samples were analyzed by HPLC-MS. For reference, the four starting materials were also analyzed by HPLC-MS, as well as MDP-DSPE[click] and MTP-α-DPPE (i.e., debenzylated reference compounds for the Bn-substituted test molecules).
[0375] For all four test solutions, the unaffected starting compound was traced. Additionally, multiple derivatives with masses +14, +16, +28, +30, and +32 were found, indicating oxidation of CH to CO moieties (+14) and CH to C-OH moieties (+16), as well as combinations of these oxidation events. The tested MDP(Bn)-DSPE[click] and MTP(Bn)-α-DPPE compounds degraded primarily through oxidation of the Bn group to a benzoic acid group (+14) followed by hydrolysis of the benzoic acid (−104). This was evidenced by the presence of primarily debenzylated MDP-DSPE[click] and MTP-α-DPPE compounds as degradation products: enhanced retention times in HPLC and enhanced masses (−90 compared to the starting compounds) in MS.
[0376] The results indicate that the Bn group in the compounds of the present invention has the highest propensity for in vivo oxidative degradation. After oxidation and cleavage of Bn, a typical MDP or MTP group is formed, which degrades in vivo in a manner similar to other MDP / MTP groups known in the art.
[0377] [Example 23] Nanobiological Synthesis Method 1 - Membrane The phospholipid, (pro)drug, and optional triglyceride or polymer are dissolved (typically in chloroform, ethanol, or acetonitrile). This solution is then evaporated under vacuum to form a film of the components. A buffer solution is then added to hydrate the film and produce a vesicle suspension. The phospholipid, (pro)drug, and optional triglyceride or polymer are dissolved (typically in chloroform, ethanol, or acetonitrile). This solution is poured or added dropwise to a gently heated buffer solution with stirring until the organic solvent has completely evaporated and a vesicle suspension is produced.
[0378] To the vesicle suspension generated using A or B, add apolipoprotein AI (apoA-I) (note that apoA-I can also be already present in B) dropwise to avoid denaturation. Then, sonicate the resulting mixture for 30 minutes using a tip sonicator while completely cooling using an external ice-water bath. Transfer the resulting solution containing the nanobiological product and other by-products to a Sartorius Vivaspin tube with a molecular weight cutoff according to the estimated size of the nanobiological product (typically, a Vivaspin tube with a cutoff of 10,000-100,000 kDa is used). Centrifuge the tube until approximately 90% of the solvent volume passes through the filter. Then, add a volume of buffer approximately equal to the volume of the remaining solution, and rotate the tube again until approximately half of the volume passes through the filter. After repeating this process twice, pass the remaining solution through a polyethersulfone 0.22 pm syringe filter to obtain the final nanobiological solution.
[0379] Method 2 - Microfluidics In an alternative approach, phospholipids, (pro)drugs, and optional triglycerides, cholesterol, steryl esters, or polymers are dissolved (typically in ethanol or acetonitrile) and loaded into a syringe. A solution of apolipoprotein AI (apoA-I) in phosphate-buffered saline is then loaded into a second syringe. Using a microfluidics pump, the contents of both syringes are mixed using a microvortex platform. The resulting solution, containing the nanobiologic and other by-products, is transferred into a Sartorius Vivaspin tube with a molecular weight cutoff depending on the estimated particle size (typically, Vivaspin tubes with a cutoff of 10,000-100,000 kDa are used). The tube is centrifuged until approximately 90% of the solvent volume passes through the filter. A volume of phosphate-buffered saline approximately equal to the volume of the remaining solution is then added, and the tube is spun again until approximately half of the volume passes through the filter. This process is repeated twice, and the remaining solution is then passed through a polyethersulfone 0.22 pm syringe filter to obtain the final nanobiologic solution.
[0380] Method 3 - Microfluidizer Another method according to the present invention uses microfluidizer technology to prepare nanoscale assemblies and the final nanobiological composition. A microfluidizer is a device for preparing small particle sizes that operates based on the submerged jet principle. To obtain nanoparticles, a premix stream is passed by a high-pressure pump through a so-called interaction chamber, which consists of a channel system within a ceramic block that splits the premix into two streams. Precisely controlled shear, turbulence, and cavitation forces are generated within the interaction chamber during microfluidization. The two streams recombine at high speed, creating shear. The resulting product can be recycled back into the microfluidizer to obtain increasingly smaller particles. Advantages of microfluidization compared to traditional milling processes include significantly reduced contamination of the final product and easier scale-up of production.
[0381] Formulation 1 The following table provides details on the preparation of HDL-derived nanoparticle formulations. First, DMPC, cholesterol, and the compounds of the present invention were dissolved in ethanol (items A, B, and D) or ethanol / DMSO 4 / 1 (items C, E, and F) at a given molar ratio, while the protein apoA-1 was dissolved separately in PBS buffer (pH = 7.5). In these formulations, the weight of the applied apoA-1 correlated with the weight of DMPC. The organic solution was mixed with the PBS buffer solution by combining them via T-junction mixing.
[0382] The resulting solution was purified by TFF (tangential flow fractionation), whereby the organic solvent was removed and the nanoparticles were dissolved in PBS. Concentration of the NP solution was performed by spin filter centrifugation. Finally, the HDL-derived nanoparticle solution was filtered through a 0.2 micrometer Acrodisk PES filter.
[0383] The final HDL-derived nanoparticle solution had a typical recovery rate of over 80% for the compounds used (Examples 2, 3, 7, 8, and 13), DMPC, and cholesterol. Recovery rates were determined using HPLC (for compounds) and art-known assays (for DMPC and cholesterol). The concentration of the final HDL-derived nanoparticle solution was approximately 2-4 mg / mL of compound.
[0384] [Table 6]
[0385] Stability of nanobiologics assessed by dynamic light scattering (DLS). The formulations of Items A-F were characterized by DLS over an 8-week period. The nanoparticles in the formulations of Examples 2, 3, 7, and 13 had Z-average (intensity-weighted average hydrodynamic size) diameters of approximately 20, 30, 20, and 45 nm, respectively. The dimensions of these nanoparticles remained constant over time, and the particle size distribution (PDI) also remained constant. Unloaded particles (Item A) were also stable over time (diameter approximately 30 nm). The nanoparticles in the formulation of Example 8 showed a diameter increase from approximately 50 to approximately 225 nm from the 2-week time point to the 5-week time point. At the 5-week time point, the dimensions were stable. Using other processing conditions, this Example 8 material could most likely be formulated into stable 10-50 nm-sized particles.
[0386] The DLS-determined Z-average diameter and PDI values of the nanoparticles of formulations A to F are shown in Figure 2 .
[0387] Tip sonication formulation A: DSPC ([816-94-4]; 2.7 mg), cholesterol (0.26 mg), and compound (0.46 mg) were dissolved in a glass vial using chloroform / methanol (9:1). The solvent was removed using a stream of argon gas, and the resulting film was dried in vacuo for >1 hour. ApoA-I PBS solution (6 mL) was added to the vial, followed by 5 minutes of bath sonication, 20 minutes of incubation at 37 °C, and then 10 minutes of tip sonication. The resulting dispersion was centrifuged to remove larger aggregates. The supernatant was transferred to a Vivapin 20 ultrafiltration unit (10 kDa cutoff) and spun down to a volume of approximately 1 mL. The resulting dispersion was diluted with PBS and spun down to 1 mL; this procedure was repeated twice. Finally, the volume was diluted to 2 mL using PBS to obtain the desired nanoparticle solution.
[0388] Tip sonication formulation B: DMPC (2.7 mg), cholesterol (0.30 mg), and compound (0.57 mg) were dissolved in a glass vial using chloroform / methanol (9:1). The solvent was removed using a stream of argon gas, and the resulting film was dried in vacuo for >1 hour. A solution of peptide-2F (apoA-I mimetic 18-mer; sequence 257 in Table 2) in 6 mL of PBS was added to the vial, followed by 5 minutes of bath sonication, 20 minutes of incubation at 37 °C, and then 5 minutes of tip sonication. The resulting dispersion was centrifuged to remove larger aggregates. The supernatant was transferred to a Vivapin 20 ultrafiltration unit (10 kDa cutoff) and spun down to approximately 1 mL. The resulting dispersion was diluted with PBS and spun down to 1 mL; this procedure was repeated twice. Finally, the volume was diluted to 2 mL using PBS to obtain the desired nanoparticle solution.
[0389] T-junction Formulation C: DMPC, cholesterol, and compound were dissolved in ethanol, while apoA-1 was dissolved in PBS buffer (pH = 7.5). T-junction mixing was applied to mix the organic solution with the buffer solution. Purification of the resulting solution was performed by TFF (tangential flow filtration), thereby removing the organic solvent. The sample was concentrated by spin-filtration. The final HDL-derived nanoparticle solution had a typical recovery rate of over 75% for compound, DMPC, and cholesterol. The concentration of the final HDL-derived nanoparticle solution was approximately 2-4 mg / mL of compound.
[0390] [Table 7]
[0391] *apoA-I or 2F-peptide used mg per mg phosphocholine PC; **apoA-I used mg per mg compound; #number average diameter.
[0392] The above examples highlight that DSPC can be used in place of DMPC (e.g., POPC can also be used), peptidomimetics can be used in place of apoA-I, and high levels of the compounds of the present disclosure can be incorporated. Additionally, tip sonication can also be used as a processing technique, e.g., in place of T-junction mixing or microfluidic mixing.
[0393] Isolation of apolipoprotein AI (apoA-I). Human apoA-I was isolated from human HDL concentrate (Bioresource Technology) according to a previously described procedure (Zamanian-Daryoush et al., 2013). Briefly, potassium bromide solution (density: 1.20 g / mL) was layered on top of the concentrate, and purified HDL was obtained by ultracentrifugation. The purified fraction was defatted by adding it to a chloroform / methanol solution. The resulting milky solution was filtered, and the apoA-I precipitate was allowed to dry overnight. The protein was refolded in 6 M guanidine hydrochloride, and the resulting solution was dialyzed against PBS. Finally, the apoA-I PBS solution was filtered through a 0.22 pm filter, and the protein identity and purity were confirmed by gel electrophoresis and size-exclusion chromatography.
[0394] [Example 24] Cryo-TEM measurements of HDL-derived nanoparticle formulations The molecular compounds of Examples 2 and 7, i.e., MDP-DSPE[click] and MDP(Bn)-DSPE[click], respectively, were formulated with 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC; CAS [18194-24-6]) and APO-A1, and with varying amounts of cholesterol, to create HDL-derived nanoparticle formulations. The table below shows the relative molar amounts of DMPC, compound, and cholesterol components used. APO-A1 was used in twice the amount (in mg) of the compounds of the present invention (in mg). Dynamic scattering (DLS) data for the processed formulations are also shown; the reported diameters and errors in parentheses are based on number-averaged DLS data. The DLS-recorded polydispersity in particle dimensions is also shown.
[0395] [Table 8]
[0396] Formulation: DMPC, cholesterol, and compounds were dissolved in ethanol (items A, C, and E) or ethanol / DMSO (items B, D, and F), while apoA-1 was dissolved in PBS buffer (pH = 7.5). A T-junction mixer was applied to mix the organic solution with the buffer solution. Purification of the resulting solution was performed by TFF (tangential flow filtration), thereby removing the organic solvent. The sample was concentrated by spin-filtration. The final HDL-derived nanoparticle solution typically yielded greater than 75% recovery of the compounds used (Examples 2 and 7), DMPC, and cholesterol. Recovery rates were determined using HPLC (for compounds) and art-known assays (for DMPC and cholesterol). The concentration of the final HDL-derived nanoparticle solution was approximately 2-4 mg / mL of compound (Example 2 or 7).
[0397] Figure 1 shows cryo-TEM images recorded for HDL-derived nanoparticles from items A to F. The 50 nm bar applies to all six images. When 0% cholesterol is used, spherical, disc-shaped particles are primarily observed (A and B; approximately 5–10 nm in size). When 10% cholesterol is applied, slightly expanded disks are mostly observed (C and D; approximately 5–25 nm in length and approximately 5 nm in thickness). When 20% cholesterol is used, clearly elongated, worm-like particles are observed. These worm-like particles have lengths of approximately 20–50 nm and thicknesses of approximately 5 nm (photo C). In photo F, the worms have lengths of approximately 50–100 nm; again, their thickness is approximately 5 nm. In F, it is also observed that the worm-like particles aggregate into larger stacks.
[0398] The results highlight that the particle size of HDL-derived nanoparticles can be controlled not only using the cholesterol content of the formulation (compare C with E, and D with F), but also by the lipophilicity of the compound and / or the substitution at the R2 position in formula (I) of the compounds of the invention (clear: compare E with F; less clear: in D the particles appear a little more elongated than in C).
[0399] Methods: Immediately prior to sample processing, 200-mesh lacey carbon-supported copper grids (Electron Microscopy Sciences) were surface plasma treated for 40 seconds using a Cressington 208 carbon coater. Next, 3 μL of HDL-derived nanoparticle sample solution was transferred to the grid. A thin film of the sample solution was then vitrified onto the grid by plunge vitrification in liquid ethane using an automated vitrification robot (FEI Vitrobot Mark IV). The processed film was stored until measurements were performed. Cryo-TEM imaging of the prepared films was performed on a Cryo-TITAN microscope (Thermo Fisher) equipped with a field emission gun (FEG), a post-column Gatan imaging filter (Model 2002), and a post-GIF 2k × 2k Gatan CCD camera (Model 794).
[0400] [Example 25] In vitro NOD2 activation assay Stimulation of human NOD2 (hNOD2) by the disclosed compounds was studied by monitoring NF-κB activation in HEK-Blue™ hNOD2 cells (Invitrogen). 50,000 HEK-Blue™ hNOD2 cells were seeded in HEK-Blue™ detection medium in flat-bottom tissue culture plates. A range of test article concentrations (compounds diluted from DMSO solution (17.8 mmol / L) first in demineralized water and then in PBS to the desired concentration) were added to the cells in the tissue culture plates. The cells were incubated overnight at 37°C with 5% CO2. The next day, the supernatant was collected into an ELISA plate, and the OD was measured at 620 nm using a spectrophotometer.
[0401] The signal in this assay is based on NOD2 stimulation by ligands, which subsequently activates NF-κB and AP-1, resulting in the production of SEAP. SEAP levels were then determined using HEK-Blue™ Detection Medium (Invitrogen). Hydrolysis of a substrate in the medium by SEAP produced a purple / blue color, which was measured using an absorbance microplate reader. OD values were mapped based on the concentration of the test article and are shown in Figure 3. Assay performance was validated using muramyl dipeptide (CAS number [53678-77-6]).
[0402] All of the test compounds (APIs) of the present invention can activate NOD2. The compounds of Examples 2, 3 and 7 have similar potencies. The compounds of Examples 8 and 13 can also activate NOD2, but to a lesser extent than the compounds of Examples 2, 3 and 7.
[0403] [Example 26] Combinatorial activity of (i) HDL-derived nanoparticles and (ii) immune checkpoint inhibition in the B16F10 mouse model 1. In Vivo Studies of Formulations Formulations for these in vivo studies were prepared by T-junction mixing followed by tangential flow filtration (TFF). Processing and purification procedures were applied as highlighted for formulations for cryo-TEM measurements (Table 8).
[0404] The compounds used were those of Examples 2, 3, 7, 8, and 13 (i.e., these example materials are collectively referred to as API in these descriptions of the in vivo studies). For the five formulations administered, the following relative ratios of components were used:
[0405] [Table 9]
[0406] Protocol and Results A panel of example APIs was formulated into HDL-derived nanoparticles (or nanobiologicals, NBs) that were screened for their antitumor activity in combination with immune checkpoint inhibitors in a B16F10 syngeneic mouse tumor model. To this end, B16F10 mouse melanoma cells were cultured in Dulbecco's Modified Eagle's Medium (DMEM) (Gibco) supplemented with 10% FBS (Gibco) and 1% penicillin / streptomycin (P / S). Cells were harvested on the day of injection and 1 x 10 viable cells were added to PBS containing 0.5% FBS. 6 Cells were resuspended at 1 × 10 cells / mL. During counting, cell viability was checked using trypan blue solution, 0.4% (Gibco). At the start of the experiment, 1 × 10 cells were resuspended in 100 μL PBS supplemented with 0.5% fetal bovine serum (FBS). 5 B16F10 tumor cells were injected subcutaneously into the flanks of 7-week-old female C57BL / 6 mice (The Jackson Laboratory).
[0407] Seven days after tumor inoculation, mice were randomized into groups with similar average group size (n=10). The average tumor size for the groups was 3.26 mm 3 After randomization, mice were ear-nicked and weighed. The dose was then calculated and aliquoted. The aliquoted doses were stored at 4°C until use.
[0408] The study consisted of a PBS control group, an immune checkpoint inhibitor (CI) group, and six treatment groups. Mice treated with immune checkpoint inhibitors received intraperitoneal injections of 200 μg of anti-CTLA-4 (clone 9H10, BioXcell) and / or 200 μg of anti-PD-1 (clone RMP1-14, BioXcell) on days 2, 4, and 8. Treatment groups consisted of NB prepared from the compound of Example 2, NB from Example 3, NB from Example 7, NB from Example 8, and NB from Example 13 in combination with the immune checkpoint inhibitor therapy (CI) described above. The dose for the treatment groups was approximately 9 mg MDP / kg (or approximately 27 mg / kg of each API contained in the NB) on days 0, 2, and 4.
[0409] Tumor growth curves are shown in Figures 4A-E, with the same PBS and CI groups mapped in each graph, allowing comparison between graphs.
[0410] PBS-treated animals or animals treated with immune checkpoint inhibitors alone did not exhibit tumor growth inhibition. All groups of animals treated with combination therapy exhibited tumor growth inhibition, which was most pronounced in groups in which the NBs of Example 2 (FIG. 4A), Example 7 (FIG. 4C), or Example 8 (FIG. 4D) were part of the combination therapy. It should be noted that the above results for the combination therapy were obtained with an applied formulation containing 10 mol% cholesterol relative to the applied 90 mol% DMPC; therefore, the dimensions of these particles were approximately 5 to a maximum of 10 nm (see cryo-TEM panels C and D in Figure 1) (see table above).
[0411] [Example 27] Single-agent activity of nanobiologics in the B16F10 mouse model Formulations for these in vivo studies were prepared by T-junction mixing followed by tangential flow filtration (TFF). Processing and purification procedures were applied as highlighted in the formulations for cryo-TEM measurements (Table 8). The table below shows the relative ratios of components used to prepare HDL-derived nanoparticles.
[0412] [Table 10]
[0413] Protocol and Results Two APIs (compounds of Example 2 and Example 7) were used to generate a series of different HDL-derived nanoparticle formulations (or nanobiologicals; nanobiologicals; NBs) and determine their efficacy. The resulting nanobiologicals were screened for single-agent antitumor activity in a B16F10 syngeneic mouse tumor model. To this end, B16F10 mouse melanoma cells were cultured in Dulbecco's Modified Eagle's Medium (DMEM) (Gibco) supplemented with 10% FBS (Gibco) and 1% penicillin / streptomycin (P / S). Cells were harvested on the day of injection and 1 x 10 viable cells were added to PBS containing 0.5% FBS. 6 Cells were resuspended at 1 × 10 cells / mL. During counting, cell viability was checked using a cell counter and analyzer (Casy). At the start of the experiment, 1 × 10 cells were resuspended in 100 μL PBS supplemented with 0.5% fetal bovine serum (FBS). 5 B16F10 tumor cells were injected subcutaneously into the flank of 7-week-old female C57BL / 6J mice (Charles River).
[0414] Seven days after tumor inoculation, mice were randomized into groups with similar average group sizes. Groups consisted of 8-10 mice. The average tumor size for the groups was 6.33 mm. 3 After randomization, mice were tattooed with numbers on their tails. The dose was then calculated and aliquoted. The aliquoted doses were stored at 4°C until use.
[0415] The study consisted of a PBS control group and five treatment groups: NB from Example 2 (formulation items 1, 3, and 4) and NB from Example 7 (formulation items 2 and 5). Treatment doses were approximately 3 mg MDP / kg (or approximately 9 mg / kg of each API contained in the NB) on days 0, 2, and 4. Tumor size was measured at designated times throughout the study. Tumor growth curves are shown in Figures 5A-C, with the same PBS group mapped on each graph to allow comparison between graphs. With the exception of NB from Example 2 (formulation item 1), all nanobiological formulations clearly demonstrated reduced tumor growth compared to the PBS control group. For both Example 2 (Figure 5A) and Example 7 (Figure 5B), the nanobiological formulation containing 20 mol% cholesterol performed best. Figure 5C shows that NB from Example 2 performed slightly better than NB from Example 7 (using formulation items 4 and 5, respectively).
[0416] In Figure 5A, the formulation of Example 2 containing 10 mol% cholesterol (item 1 in the table above) exhibited minimal single-agent activity (compared to PBS). Surprisingly, in comparison, the formulations of Example 2 containing 20 mol% cholesterol (items 3 and 4 in the table above) exhibited greatly enhanced tumor suppression. This can also be seen for the formulation of Example 7 (Figure 5B). Clearly, the dimensions of the formed particles play a crucial role in the activity of the prepared HDL-derived nanoparticles: the 10% cholesterol formulation yields spherical or slightly elongated, disc-shaped particles with dimensions of 5–10 nm, whereas the 20% cholesterol formulation yields elongated, worm-like particles approximately 15–50 nm in length and approximately 5 nm thick (compare panels C and E in Figure 1, cryo-TEM data).
[0417] The disclosed HDL-derived nanoparticles have certain dimensions, and these characteristics find particular use in generating stable and potent HDL-derived NPs. Without being bound by theory, it is believed that the disclosed HDL-derived nanoparticles improve the (multivalent) presentation of the MDP (or MDP(Bn) or MTP or MTP(Bn)) moiety to cells, dramatically improving their efficacy.
