TECHNICAL FIELD

The present disclosure relates generally to Cellular Signalling inhibitors, compositions and formulations comprising the same, and uses thereof. In particular, the present disclosure provides CSF-IR inhibitors of BLZ-945-lipids conjugates, GW2580-lipid conjugates and PLX-3397-lipid conjugates demonstrating sustained inhibition of CSF/CSF-1R signalling pathway with decreased toxicity. The present disclosure also provides supramolecular combinatorial therapeutics, wherein the CSF-IR inhibitor is combined with one or more of a chemotherapeutic agent, a kinase inhibitor, and an immunoregulator, each of which is optionally conjugated with a lipid. Background

Targeted therapies have been in the limelight as cancer therapeutics for the last few years. They have resulted in high response rates and improved overall survival in patients with cancer. However, consistent with other oncogene-targeted therapies, initial patient response is of limited durability and tumors eventually relapse. ¹ The tumor microenvironment is increasingly recognized to play an important role in tumor proliferation, invasion, metastasis, and chemoresistance. It provides a conducive niche to the tumor through immunosuppression. Overcoming this immunosuppressive nature of the tumor microenvironment has been of particular interest in cancer therapy. Tumor cells manipulate the surrounding environment by producing cytokines that suppress cytolytic T-cells and recruit immunosuppressive cells. ¹¹ Colony stimulating factor 1 (CSF-1) is one such cytokine secreted by several cancer cell types. It induces the proliferation and differentiation of immunosuppressive myeloid cells such as M2 polarized macrophages and myeloid derived suppressor cells (MDSC) by binding to the CSF-1 receptor (CSF-IR) on cell surface. ¹¹¹ Cellular signalling mediated by colony-stimulating factor 1 (CSF1) and its receptor CSF-IR plays a critical role in monocyte differentiation and generation and activity of tissue-resident macrophages. The overexpression of CSF1 is associated with poor prognosis in breast, ovarian, and prostate cancer. Coincidentally, increased TAMs (tumor-associated macrophages) density also designates poor prognostic value, suggesting that CSF1-CSF1R axis may have an important role towards activity of TAMs. ^lv ' ^{v vl} The CSF1/CSF1R signalling pathway is targeted in the treatment against numerous malignancies, including breast, leukaemia, and glioblastoma. Studies have demonstrated that TAMs undergo turnover in a CSF-IR dependent manner, with continuous inhibition of the CSF-IR pathway being essential for depletion of TAMs and serving as an anticancer therapy. Therefore, the immunosuppressive tumor environment mediated by CSF-1 helps tumor cells escape killing by immune cells and assists them to metastasize. Since CSF-IR regulates the functioning of macrophages impacting tumor progression, inhibiting the CSF-IR pathway has emerged as a major therapeutic goal in cancer. Recently, some of the CSF-IR inhibitors had shown promising results in terms of potency, selectivity and bioavailability of cFMS kinase activity ^vu Among them some of the well-known inhibitors which are in the clinical phase trials are BLZ-945, GW2580, PLX-3397 etc. Although high in potency, these inhibitors fail to achieve a sustained inhibition of CSF-IR and are associated with toxicity to normal cells. Accordingly, there remains an urgent need for CSF-IR inhibitors with an improved activity profile while exhibiting decreased toxicity.

Summary The present application describes the design of novel CSF-IR inhibitors that can preferentially accumulate in the tumor microenvironment and exert sustained inhibition of the target molecule, overcoming the dose-limiting toxic effects and achieving superior antitumor efficacy compared to currently available CSF-IR inhibitors. The present invention is directed to hydrophobic, lipophilic prodrugs that lead to increased effective drug accumulation in tumor via enhanced permeability and retention (EPR) phenomenon leading to improved efficacy. The lipids used in these prodrugs include phospholipids, cholesterol, fatty acids etc. The present invention describes prodrugs of CSF-IR inhibitors that can assemble into supramolecular structure with improved pharmacokinetic profile such as long circulation time, enhanced uptake and sustained release of drug inside tumor. The CSF-IR uptake into tumor can be achieved in higher amounts by making supramolecular assemblies in aqueous buffer along with the addition of co-lipids to form supramolecules with an average particle size below 200 nm. Degradation of the supramolecular assembly as well as the prodrug releases effective drug inside the cell. Pharmaceutical compositions of prodrug of a CSF-IR inhibitor comprise a linker wherein CSF-IR is coupled through ester, ether, amide, or other covalent conjugation with the linker. The lipid molecule can be cholesterol, oleic acid, alpha tocopherol, fatty acid or another naturally occurring lipid molecule which is conjugated to drug molecule through a suitable linker/spacer. The spacer can be composed of aliphatic dicarboxylic acid, unsaturated dicarboxylic acid, aldaric acid, fumaric acid, propargylic acid, acetylene dicarboxylic acid, aromatic/hetero aromatic dicarboxylic acid, ethylene glycol, diethylene glycol, natural or unnatural amino acids individually or in any combinations.

Certain exemplary embodiments provide supramolecular combinatorial therapeutics, wherein a CSF-IR inhibitor is combined with one or more of a kinase inhibitor, or a chemotherapeutic drug, or a tumor-targeting antibody, each of which is optionally conjugated with a lipid. Without limitations, the antibody can be useful for therapeutic purposes (i.e., a therapeutic antibody) or for targeting the supramolecular combinatorial therapeutic to a desired site (i.e., a targeting antibody). In some embodiments, the supramolecular combinatorial therapeutic further comprises an immunomodulator, which can include another CSF-IR inhibitor (s). Immunomodulators are active agents of immunotherapy, and can either activate or suppress an immune response. In certain embodiments, the immunomodulator activates and stimulates an immune response against cancer cells, non-limiting examples of which include immune cells (e.g., natural killer cells, lymphokine-activated killer cells, cytotoxic T cells and dendritic cells), antibodies (e.g., anti-PD-Ll and anti-PD-1 antibodies, anti-CD52, anti-VEGF-A, anti- CD30, anti-EGFR, anti- CD33, anti-CD20, anti-CTLA4, and anti-HER-2 antibodies), and cytokines (e.g., interferons and interleukins). In certain exemplary embodiments, the immunomodulator is conjugated with a lipid.

The terms such as "excipient", "carrier", "pharmaceutically acceptable carrier" or the like are used interchangeably herein. In some embodiments, the carrier inhibits the degradation of the active agent, e.g. a composition as described herein.

In some embodiments, the pharmaceutical composition comprising a supramolecular combinatorial therapeutic can be a parenteral dose form. Since administration of parenteral dosage forms typically bypasses the patient's natural defenses against contaminants, parenteral dosage forms are preferably sterile or capable of being sterilized prior to administration to a patient. Examples of parenteral dosage forms include, but are not limited to, solutions ready for injection, dry products ready to be dissolved or suspended in a pharmaceutically acceptable vehicle for injection, suspensions ready for injection, and emulsions. In addition, controlled- release parenteral dosage forms can be prepared for administration of a patient, including, but not limited to, DUROS ^® -type dosage forms and dose-dumping.

Suitable vehicles that can be used to provide parenteral dosage forms of a composition as described herein are well known to those skilled in the art. Examples include, without limitation: sterile water; water for injection USP; saline solution; glucose solution; aqueous vehicles such as but not limited to, sodium chloride injection, Ringer's injection, dextrose Injection, dextrose and sodium chloride injection, and lactated Ringer's injection; water- miscible vehicles such as, but not limited to, ethyl alcohol, polyethylene glycol, and propylene glycol; and non-aqueous vehicles such as, but not limited to, corn oil, cottonseed oil, peanut oil, sesame oil, ethyl oleate, isopropyl myristate, and benzyl benzoate. Compounds that alter or modify the solubility of a pharmaceutically acceptable salt can also be incorporated into the parenteral dosage forms of the disclosure, including conventional and controlled-release parenteral dosage forms.

Pharmaceutical compositions can also be formulated to be suitable for oral administration, for example as discrete dosage forms, such as, but not limited to, tablets (including without limitation scored or coated tablets), pills, caplets, capsules, chewable tablets, powder packets, cachets, troches, wafers, aerosol sprays, or liquids, such as but not limited to, syrups, elixirs, solutions or suspensions in an aqueous liquid, a non-aqueous liquid, an oil-in-water emulsion, or a water-in-oil emulsion. Such compositions contain a predetermined amount of the pharmaceutically acceptable salt of the disclosed compounds, and may be prepared by methods of pharmacy well known to those skilled in the art. See generally, Remington: The Science and Practice of Pharmacy, 21st Ed., Lippincott, Williams, and Wilkins, Philadelphia PA. (2005).

The compounds, compositions and methods described herein can be administered to a subject having or diagnosed as having cancer. In some embodiments, the methods described herein comprise administering an effective amount of compositions described herein to a subject in order to alleviate a symptom of a cancer. As used herein, "alleviating a symptom of a cancer" is ameliorating any condition or symptom associated with the cancer. As compared with an equivalent untreated control, such reduction is by at least 5%, 10%, 20%, 40%, 50%, 60%, 80%), 90%), 95%), 99% or more as measured by any standard technique. A variety of means for administering the compositions described herein to subjects are known to those of skill in the art. Such methods can include, but are not limited to oral, parenteral, intravenous, intramuscular, subcutaneous, transdermal, airway (aerosol), pulmonary, cutaneous, topical, injection, or intratumoral administration. Administration can be local or systemic.

The term "effective amount" as used herein refers to the amount of a composition described herein needed to alleviate at least one or more symptom of the disease or disorder, and relates to a sufficient amount of pharmacological composition to provide the desired effect. The term "therapeutically effective amount" therefore refers to an amount of a composition described herein that is sufficient to provide a particular anti-tumor effect when administered to a typical subject. An effective amount as used herein, in various contexts, would also include an amount sufficient to delay the development of a symptom of the disease, alter the course of a symptom disease (for example but not limited to, slowing the progression of a symptom of the disease), or reverse a symptom of the disease. Thus, it is not generally practicable to specify an exact "effective amount". However, for any given case, an appropriate "effective amount" can be determined by one of ordinary skill in the art using only routine experimentation.

In certain embodiments, an effective dose of a composition as described herein can be administered to a patient once. In certain embodiments, an effective dose of a composition as described herein can be administered to a patient repeatedly. For systemic administration, subjects can be administered a therapeutic amount of a composition as described herein, such as, e.g. 0.1 mg/kg, 0.5 mg/kg, 1.0 mg/kg, 2.0 mg/kg, 2.5 mg/kg, 5 mg/kg, 10 mg/kg, 15 mg/kg, 20 mg/kg, 25 mg/kg, 30 mg/kg, 40 mg/kg, 50 mg/kg, or more. In some embodiments, after an initial treatment regimen, the treatments can be administered on a less frequent basis. For example, after treatment biweekly for three months, treatment can be repeated once per month, for six months or a year or longer. Treatment according to the methods described herein can reduce levels of a marker or symptom of a condition, e.g. tumor size and/or growth by at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80 % or at least 90% or more.

The dosage of a composition as described herein can be determined by a physician and adjusted, as necessary, to suit observed effects of the treatment. With respect to duration and frequency of treatment, it is typical for skilled clinicians to monitor subjects in order to determine when the treatment is providing therapeutic benefit, and to determine whether to increase or decrease dosage, increase or decrease administration frequency, discontinue treatment, resume treatment, or make other alterations to the treatment regimen. The dosing schedule can vary from once a week to daily depending on a number of clinical factors, such as the subject's sensitivity a composition as described herein. The desired dose or amount of activation can be administered at one time or divided into subdoses, e.g., 2-4 subdoses and administered over a period of time, e.g., at appropriate intervals through the day or other appropriate schedule. In some embodiments, administration can be chronic, e.g., one or more doses and/or treatments daily over a period of weeks or months. Examples of dosing and/or treatment schedules are administration daily, twice daily, three times daily or four or more times daily over a period of 1 week, 2 weeks, 3 weeks, 4 weeks, 1 month, 2 months, 3 months, 4 months, 5 months, or 6 months, or more. A composition as described herein can be administered over a period of time, such as over a 5 minute, 10 minute, 15 minute, 20 minute, or 25 minute period.

The dosage ranges for the administration of a composition as described herein, according to the methods described herein depend upon, for example, the form of a composition as described herein, its potency, and the extent to which symptoms, markers, or indicators of a condition described herein are desired to be reduced, for example the percentage reduction desired for tumor growth. The dosage should not be so large as to cause adverse side effects. Generally, the dosage will vary with the age, condition, and sex of the patient and can be determined by one of skill in the art. The dosage can also be adjusted by the individual physician in the event of any complication.

The efficacy of a composition as described herein in, e.g. the treatment of a condition described herein, or to induce a response as described herein can be determined by the skilled clinician. However, a treatment is considered "effective treatment," as the term is used herein, if one or more of the signs or symptoms of a condition described herein are altered in a beneficial manner, other clinically accepted symptoms are improved, or even ameliorated, or a desired response is induced e.g., by at least 10% following treatment according to the methods described herein. Efficacy can be assessed, for example, by measuring a marker, indicator, symptom, and/or the incidence of a condition treated according to the methods described herein or any other measurable parameter appropriate, e.g. tumor size and/or growth. Efficacy can also be measured by a failure of an individual to worsen as assessed by hospitalization, or need for medical interventions (i.e., progression of the disease is halted). Methods of measuring these indicators are known to those of skill in the art and/or are described herein. Treatment includes any treatment of a disease in an individual or an animal (some non-limiting examples include a human or an animal) and includes: (1) inhibiting the disease, e.g., preventing a worsening of symptoms (e.g. pain or inflammation); or (2) relieving the severity of the disease, e.g., causing regression of symptoms. An effective amount for the treatment of a disease means that amount which, when administered to a subject in need thereof, is sufficient to result in effective treatment as that term is defined herein, for that disease. Efficacy of an agent can be determined by assessing physical indicators of a condition or desired response, (e.g. tumor size and/or growth). It is well within the ability of one skilled in the art to monitor efficacy of administration and/or treatment by measuring any one of such parameters, or any combination of parameters. Efficacy can be assessed in animal models of a condition described herein, for example treatment of cancer. When using an experimental animal model, efficacy of treatment is evidenced when a statistically significant change in a marker is observed, e.g. a decreased in tumor size and/or growth.

As used herein, a "subject" means a human or animal. Usually the animal is a vertebrate such as a primate, rodent, domestic animal or game animal. Primates include chimpanzees, cynomologous monkeys, spider monkeys, and macaques, e.g., Rhesus. Rodents include mice, rats, woodchucks, ferrets, rabbits and hamsters. Domestic and game animals include cows, horses, pigs, deer, bison, buffalo, feline species, e.g., domestic cat, canine species, e.g., dog, fox, wolf, avian species, e.g., chicken, emu, ostrich, and fish, e.g., trout, catfish and salmon. In some embodiments, the subject is a mammal, e.g., a primate, e.g., a human. The terms, "individual," "patient" and "subject" are used interchangeably herein.

Preferably, the subject is a mammal. The mammal can be a human, non-human primate, mouse, rat, dog, cat, horse, or cow, but is not limited to these examples. Mammals other than humans can be advantageously used as subjects that represent animal models of cancer. A subject can be male or female. A subject can be one who has been previously diagnosed with or identified as suffering from or having a condition in need of treatment (e.g. cancer) or one or more complications related to such a condition, and optionally, have already undergone treatment for cancer or the one or more complications related to cancer. Alternatively, a subject can also be one who has not been previously diagnosed as having cancer or one or more complications related to cancer. For example, a subject can be one who exhibits one or more risk factors for cancer or one or more complications related to cancer or a subject who does not exhibit risk factors.

A "subject in need" of treatment for a particular condition can be a subject having that condition, diagnosed as having that condition, or at risk of developing that condition.

The term "agent" refers generally to any entity which is normally not present or not present at the levels being administered to a cell, tissue or subject. An agent can be selected from a group including but not limited to: polynucleotides; polypeptides; small molecules; and antibodies or antigen-binding fragments thereof. A polynucleotide can be RNA or DNA, and can be single or double stranded, and can be selected from a group including, for example, nucleic acids and nucleic acid analogues that encode a polypeptide. A polypeptide can be, but is not limited to, a naturally-occurring polypeptide, a mutated polypeptide or a fragment thereof that retains the function of interest. Further examples of agents include, but are not limited to a nucleic acid aptamer, peptide-nucleic acid (PNA), locked nucleic acid (LNA), small organic or inorganic molecules; saccharide; oligosaccharides; polysaccharides; biological macromolecules, peptidomimetics; nucleic acid analogs and derivatives; extracts made from biological materials such as bacteria, plants, fungi, or mammalian cells or tissues and naturally occurring or synthetic compositions. An agent can be applied to the media, where it contacts the cell and induces its effects. Alternatively, an agent can be intracellular as a result of introduction of a nucleic acid sequence encoding the agent into the cell and its transcription resulting in the production of the nucleic acid and/or protein environmental stimuli within the cell. In some embodiments, the agent is any chemical, entity or moiety, including without limitation synthetic and naturally-occurring non-proteinaceous entities. In certain embodiments the agent is a small molecule having a chemical moiety selected, for example, from unsubstituted or substituted alkyl, aromatic, or heterocyclyl moieties including macrolides, leptomycins and related natural products or analogues thereof. Agents can be known to have a desired activity and/or property, or can be selected from a library of diverse compounds. As used herein, the term "small molecule" can refer to compounds that are "natural product-like," however, the term "small molecule" is not limited to "natural product-like" compounds. Rather, a small molecule is typically characterized in that it contains several carbon— carbon bonds, and has a molecular weight more than about 50, but less than about 5000 Daltons (5 kD). Preferably the small molecule has a molecular weight of less than 3 kD, still more preferably less than 2 kD, and most preferably less than 1 kD. In some cases it is preferred that a small molecule have a molecular mass equal to or less than 700 Daltons.

As used herein, the term "inhibitor" refers to an agent which can decrease the expression and/or activity of the targeted expression product (e.g. mRNA encoding the target or a target polypeptide), e.g. by at least 10% or more, e.g. by 10% or more, 50% or more, 70% or more, 80% or more, 90% or more, 95% or more, or 98 % or more. The efficacy of an inhibitor of, for example, PI3K, e.g. its ability to decrease the level and/or activity of PI3K can be determined, e.g. by measuring the level of a PI3K polypeptide (and/or mRNA encoding such a polypeptide) and/or the activity of PI3K. Methods for measuring the level of a given mRNA and/or polypeptide are known to one of skill in the art, e.g. RTPCR with primers can be used to determine the level of RNA and Western blotting with an antibody can be used to determine the level of a polypeptide. The activity of, e.g. PI3K can be determined using methods known in the art and described above herein. .

As used herein, the terms "treat," "treatment," "treating," or "amelioration" refer to therapeutic treatments, wherein the object is to reverse, alleviate, ameliorate, inhibit, slow down or stop the progression or severity of a condition associated with a disease or disorder, e.g. cancer. The term "treating" includes reducing or alleviating at least one adverse effect or symptom of a condition, disease or disorder associated with a cancer. Treatment is generally "effective" if one or more symptoms or clinical markers are reduced. Alternatively, treatment is "effective" if the progression of a disease is reduced or halted. That is, "treatment" includes not just the improvement of symptoms or markers, but also a cessation of, or at least slowing of, progress or worsening of symptoms compared to what would be expected in the absence of treatment. Beneficial or desired clinical results include, but are not limited to, alleviation of one or more symptom(s), diminishment of extent of disease, stabilized (i.e., not worsening) state of disease, delay or slowing of disease progression, amelioration or palliation of the disease state, remission (whether partial or total), and/or decreased mortality, whether detectable or undetectable. The term "treatment" of a disease also includes providing relief from the symptoms or side-effects of the disease (including palliative treatment).

As used herein, the term "composition" or "pharmaceutical composition" are used interchangeably and refers to the active agent in combination with a pharmaceutically acceptable carrier e.g. a carrier commonly used in the pharmaceutical industry. The phrase "pharmaceutically acceptable" is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

As used herein, the term "administering," refers to the placement of a compound as disclosed herein into a subject by a method or route which results in at least partial delivery of the agent at a desired site. Pharmaceutical compositions comprising the compounds disclosed herein can be administered by any appropriate route which results in an effective treatment in the subject. As used herein, the term "amphiphilic" refers to a molecule that has both a hydrophobic portion and a lipophobic portion, i.e. at least one a polar, water-soluble group and at least one a nonpolar, water- insoluble group. Typically, in a two phase system having a polar, aqueous phase and a non-polar, non-aqueous phase, an amphiphilic molecule will partition to the interface of the two phases. In simpler non limiting terms, an amphiphile is a molecule that is soluble in both an aqueous environment and a non-aqueous environment. The term "amphiphile" refers to an amphiphilic molecule.

As used herein the term "comprising" or "comprises" is used in reference to compositions, methods, and respective component(s) thereof, that are essential to the method or composition, yet open to the inclusion of unspecified elements, whether essential or not.

The singular terms "a," "an," and "the" include plural referents unless context clearly indicates otherwise. Similarly, the word "or" is intended to include "and" unless the context clearly indicates otherwise. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of this disclosure, suitable methods and materials are described below. The abbreviation, "e.g." is derived from the Latin exempli gratia, and is used herein to indicate a non-limiting example. Thus, the abbreviation "e.g." is synonymous with the term "for example."

2. Attaching of other part to the molecule to make the final compound. Scheme 1

Preparation of the ligand

In scheme 1, cholesterol was converted to compound 3 using the reported procedure. Compound 3 was further treated with cyclic acid anhydride in presence of pyridine at room temperature for overnight to yield compound 4.

Starting from previously reported compound 3, tosylation of the hydroxyl group was performed using known procedure and then converted to compound 6 using sodium azide at room temperature. (Scheme 2). The azide thus prepared was reduced to amine, which was again treated with cyclic acid anhydride to give carboxylic acid derivative 8.

Scheme 4

By following a known procedure compound 2 was transformed to azide derivative 12 in presence of BF ₃ .Et20 and trimethyl silyl azide. (Scheme 4) The azide thus produced was successively reduced and then treated with cyclic acid anhydride of different chain length to prepare compound 14.

Scheme 5

Different amino acid with varying chain lengths as well as di/tripeptide of various combination was directly attached with commercially available cholesteroyl chloride in known alkaline condition to give different cholesterol acid derivatives 15. (Scheme 5)

The acid thus prepared was then coupled with commercially available alicyclic derivative of N-Boc amine-alcohols and subsequently deprotected to get the amines. (Scheme 6)

Scheme 6

The amine salt (16- 20) thus produced was treated with freshly prepared sulphoxide derivative (Scheme 7) using diisopropyl ethyl amine in N-methyl morpholine at elevated temperature for 3 days.™ The compound formation was monitored by using TLC method. (Scheme 8) The crude reaction mixture was then evaporated and then purified by column chromatography to get the final compound.

Formulation

Supramolecular nanostructures were formulated using thin film hydration method with varying mole ratios of phospholipids (such as HSPC, POPC, SOPC, Egg PC, etc.), PEGylated- phospholipids (such as DSPE-PEG) and CSF1R inhibitor conjugates. % Encapsulation efficiency of the CSF1R inhibitors in the supramolecules was determined by UV spectrophotometry. Average size, polydispersity index (PDI) and surface potential of the nanoparticles were measured by Dynamic light scattering (DLS).

These supramolecules were lyophilized (5% Lactose solution was used as cryo-protectant) over 16-20 hrs. The amorphous white solid powder formed thereafter was reconstituted by adding required volume of water. DLS study of this reconstituted supramolecular formulation reveals similar size, PDI, surface potential of supramolecules as it was before lyophilization. To clarify the characteristics of these supramolecules, some examples of its implementation are described hereby:

EXAMPLE.1

HSPC, POPC, IO-806 03 and DSPE-PEG, taken in 55:35:5:5 mol% ratio, were dissolved in Chloroform. All lipid solutions were mixed homogeneously in round bottom flask and organic solvent was evaporated by rotary evaporator resulting in a thin lipid film. The lipid film was kept under high vacuum for 3-4 hr. It was, then, hydrated (by adding 5% Lactose solution to it) for 1.0 h at 60°C in hot water bath. Next, hydrated nanoparticles were sequentially extruded through 400nm, 200nm and lOOnm pore size membrane held by filter support for 11 times at 60°C using Avanti extruder supported over hot plate. It is evident from UV measurement that 4.2 mol% of IO-806 03 was encapsulated in the supramolecule. DLS measurement reveals average size of the nanoparticles to be 153.4 nm, PDI 0.100 and surface potential -20.9 mV. The resulting solution was lyophilized and stored at 4°C.

EX AMPLE.2

HSPC, POPC, IO-806 02 and DSPE-PEG, taken in 55:35:5:5 mol% ratio, were dissolved in Chloroform. All lipid solutions were mixed homogeneously in round bottom flask and organic solvent was evaporated by rotary evaporator resulting in a thin lipid film. The lipid film was kept under high vacuum for 3-4 hr. It was, then, hydrated (by adding 5% Lactose solution to it) for 1.0 h at 60°C in hot water bath. Next, hydrated nanoparticles were sequentially extruded through 400nm, 200nm and lOOnm pore size membrane held by filter support for 11 times at 60°C using Avanti extruder supported over hot plate. It is evident from UV measurement that 4.0 mol% of IO-806 02 was encapsulated in the supramolecule. DLS measurement reveals average size of the nanoparticles to be 131.5 nm, PDI 0.064 and surface potential -24.8 mV. The resulting solution was lyophilized and stored at 4°C.

EXAMPLE.3 HSPC, POPC, IO-803 01 and DSPE-PEG, taken in 55:35:5:5 mol% ratio, were dissolved in Chloroform. All lipid solutions were mixed homogeneously in round bottom flask and organic solvent was evaporated by rotary evaporator resulting in a thin lipid film. The lipid film was kept under high vacuum for 3-4 hr. It was, then, hydrated (by adding 5% Lactose solution to it) for 1.0 h at 60°C in hot water bath. Next, hydrated nanoparticles were sequentially extruded through 400nm, 200nm and lOOnm pore size membrane held by filter support for 11 times at 60°C using Avanti extruder supported over hot plate. It is evident from UV measurement that 4.1 mol% of IO-803_01was encapsulated in the supramolecule. DLS measurement reveals average size of the nanoparticles to be 137.9 nm, PDI 0.058 and surface potential -24.5 mV. The resulting solution was lyophilized and stored at 4°C.

EXAMPLE .4 HSPC, POPC, IO-801 03 and DSPE-PEG, taken in 50:35: 10:5 mol% ratio, were dissolved in Chloroform. All lipid solutions were mixed homogeneously in round bottom flask and organic solvent was evaporated by rotary evaporator resulting in a thin lipid film. The lipid film was kept under high vacuum for 3-4 hr. It was, then, hydrated (by adding 5% Lactose solution to it) for 1.0 h at 60°C in hot water bath. Next, hydrated nanoparticles were sequentially extruded through 400nm, 200nm and lOOnm pore size membrane held by filter support for 11 times at 60°C using Avanti extruder supported over hot plate. It is evident from UV measurement that 9.4 mol% of IO-801 03 was encapsulated in the supramolecule. DLS measurement reveals average size of the nanoparticles to be 146.0 nm, PDI 0.043 and surface potential -28.2 mV. The resulting solution was lyophilized and stored at 4°C. EXAMPLE 5

HSPC, POPC, IO-801 02 and DSPE-PEG, taken in 50:30: 15:5 mol% ratio, were dissolved in Chloroform. All lipid solutions were mixed homogeneously in round bottom flask and organic solvent was evaporated by rotary evaporator resulting in a thin lipid film. The lipid film was kept under high vacuum for 3-4 hr. It was, then, hydrated (by adding 5% Lactose solution to it) for 1.0 h at 60°C in hot water bath. Next, hydrated nanoparticles were sequentially extruded through 400nm, 200nm and lOOnm pore size membrane held by filter support for 11 times at 60°C using Avanti extruder supported over hot plate. It is evident from UV measurement that 6.3 mol% of IO-801 02 was encapsulated in the supramolecule. DLS measurement reveals average size of the nanoparticles to be 181.3 nm, PDI 0.137 and surface potential 3.46 mV. The resulting solution was lyophilized and stored at 4°C.
