The present disclosure relates generally to chemical compounds. More particularly, embodiments relate to pharmaceuticals. Even more particularly, embodiments relate to insulin-based drug conjugates.
The prevalence of conditions associated with insulin resistance, including metabolic syndrome and type 2 diabetes, has been increasing over the past few decades. Insulin resistance is identified as an impaired biologic response to insulin stimulation of target tissues, primarily the liver, muscle, and adipose tissue. The consequences of insulin resistance can result in hyperglycemia, hypertension, dyslipidemia, visceral adiposity, hyperuricemia, elevated inflammatory markers, endothelial dysfunction, and a prothrombic state. Ultimately, insulin resistance can lead to metabolic syndrome, nonalcoholic fatty liver disease (NAFLD), and type 2 diabetes mellitus. With nearly 500 million adults (20-79 years) worldwide currently living with diabetes (and the number is expected to increase to 700 million by 2045), the burden on the health care system will be enormous.
Current treatments for insulin resistance, type 2 diabetes and metabolic syndrome focus on stimulation of insulin secretion ((sulfonylureas, meglitinides, incretin mimetics) and insulin sensitivity (thiazolidinediones (or TZDs) and metformin) as well as concentrated high doses of insulin called Humulin 500. In addition, TZDs can have serious side effects, including weight gain, swelling, and an increase risk of heart failure and fractures. Over time, all these therapies eventually lead to a decrease in insulin sensitivity and a progressive disease state. Accordingly, there is a worldwide need for cost effective therapies to treat insulin resistance, metabolic syndrome and type 2 diabetes. The embodiments disclosed herein, address this need.

The present disclosure provides a particular bioactive polypeptide hormones of the insulin family and it's homologs as drug-conjugates that are effective therapeutics for metabolic disorders, including, but not limited to, Type 2 diabetes, Insulin resistance, metabolic syndrome and type 1 diabetes. Again without wishing to be bound to any particular theory of action, Insulin signals by binding to its insulin receptor (IR) on the surface of responding cells. The IR receptor relies on the insulin receptor substrate proteins 1 and 2 adaptors or organizing and coordinating its signal transduction which culminates among other things on the translocation of glucose transporters to the cell surface for the import of glucose from the blood into cells for metabolic consumption and storage. Like many other receptors signal transduction from the insulin receptor involves many proteins that transect several other signaling pathways and it is thus, affected by crosstalk from other cellular responses. In particular, pro-inflammatory pathways triggered by cytokines such as interleukin 6 and interferon induce their own negative feedback responses in order to self-limit their own actions. Thus, under chronic pro-inflammatory conditions such as those taking place in obese subjects or those suffering from metabolic syndrome and other related conditions [2] cytokine-induced SOCS activation causes inhibition of the insulin receptor signaling capability first by competing with receptor signaling intermediates for IRS1/2 binding and secondly by inducing CRL-mediated ubiquitination and degradation of IRS1/2. The elevated SOCS activity and concomitant decrease in the IRS1/2 protein levels impair insulin receptor signaling consequently establishing the insulin-resistance pathology. The present invention relates to novel insulin, insulin-fusion proteins and insulin homologs protein-small molecule drug conjugates, where conjugation takes place through the use of cleavable and non-cleavable linkers. The small molecules chemically linked to the protein carrier are imported into the specific insulin-responsive target tissue or cell through receptor-mediated endocytosis and released from the carrier protein through enzymatic cleavage of the linker-drug moiety or through lysosomal degradation of the carrier protein. Free drug then act to modify insulin receptor-triggered biochemical pathways that are altered in conditions of insulin-resistance such as SOCS-mediated CRL-dependent IRS-1/2 degradation. Drug will correct altered pathway allowing resensitization of receptor signaling. This will greatly aid in the resolution of pathologies either initiated at the onset of insulin resistance or exacerbated by it.

An aspect of the disclosure relates to an Insulin polypeptide or a bio-active homolog polypeptide thereof comprising an amino acid sequence set forth in SEQ ID NO:1 or SEQ ID NO:2.
In one embodiment, the present disclosure provides compounds (e.g., compounds of formula II or III), or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, useful for the treatment of disorders, such as insulin resistance, type 2 diabetes and metabolic syndrome. The compounds of the disclosure, or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, may comprise biologically active polypeptides or hormones modified to include the attachment of therapeutic compounds using linkers. Further, the present disclosure provides pharmaceutical compositions comprising compounds of the disclosure, or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, as well as methods, uses, compounds for use, medicaments, and including pharmaceutical compositions for use comprising said compounds. The present disclosure also provides compounds comprising therapeutic compounds and a linker, useful for the preparation of the compounds comprising biologically active polypeptides or hormones modified to include the attachment of therapeutic compounds using linkers (e.g., compounds of Formula I, or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof). The present disclosure also provides bio-active homolog polypeptides of human insulin.
The compounds of the disclosure, or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, comprising biologically active polypeptides or hormones modified to include the attachment of therapeutic compounds using linkers provide a highly targeted therapy useful in the treatment of insulin resistance, type 2 diabetes and metabolic syndrome. The biologically active polypeptide or hormone selectively interacts with its cell surface receptor and it taken up by the cell through receptor mediated endocytosis. The compound of the disclosure is then degraded by the cell, releasing the therapeutic compound within the cell. Treatment of insulin resistance, type 2 diabetes and metabolic syndrome with the compounds of the disclosure, or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, comprising biologically active polypeptides or hormones modified to include the attachment of therapeutic compounds using linkers is specific, potentially reducing off-target effects compared to standard therapies, and may exhibit high affinity for target cells, resulting in low immunogenicity. The compounds of the disclosure, or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, comprising biologically active polypeptides or hormones modified to include the attachment of therapeutic compounds using linkers may be very potent in the treatment of insulin resistance, type 2 diabetes and metabolic syndrome and are may be stable at physiological pH, in circulation, and in storage.
Due to the specificity of the compounds of the disclosure, or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, comprising biologically active polypeptides or hormones modified to include the attachment of therapeutic compounds using linkers for their targeted cells and receptors, a lower therapeutic dose of therapeutic compound may be required, reducing side effects and potentially providing a wider therapeutic window. For example, the therapeutic compounds TAS4464 and pevonedistat, both neddylation inhibitors detailed herein, show promise for the treatment of cancer. But these compounds have apparently struggled in clinical trials due to issues with toxicity. Using the compounds of the disclosure, or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, reduced amounts of therapeutic compound should be required to exhibit a therapeutic effect, likely only picomolar therapeutic compound concentration doses instead of nanomolar or micromolar concentration doses of therapeutic compound, possibly reducing the therapeutic compound's toxicity. Remarkably, these dose concentrations are consistent with the dose concentrations typically utilized in human insulin polypeptide therapy, wherein the human insulin plasma levels peaks at 1500 pmol/L 2 hours after subcutaneous injection [1] of some forms of recombinant Insulin.
The present disclosure provides in particular bioactive polypeptide hormones of the insulin family and it's homologs as drug-conjugates that are effective therapeutics for metabolic disorders, including, but not limited to, Type 2 diabetes, Insulin resistance, metabolic syndrome and type 1 diabetes. Again without wishing to be bound to any particular theory of action, Insulin signals by binding to its insulin receptor (IR) on the surface of responding cells. The IR receptor relies on the insulin receptor substrate proteins 1 and 2 adaptors for organizing and coordinating its signal transduction which culminates among other things on the translocation of glucose transporters to the cell surface for the import of glucose from the blood into cells for metabolic consumption and storage. Like many other receptors signal transduction from the insulin receptor involves many proteins that transect several other signaling pathways and it is thus, affected by crosstalk from other cellular responses. In particular, pro-inflammatory pathways triggered by cytokines such as interleukin 6 and interferon induce their own negative feedback responses in order to self-limit their own actions. Thus, under chronic pro-inflammatory conditions such as those taking place in obese subjects or those suffering from metabolic syndrome and other related conditions [2] cytokine-induced SOCS activation causes inhibition of the insulin receptor signaling capability first by competing with receptor signaling intermediates for IRS1/2 binding and secondly by inducing CRL-mediated ubiquitination and degradation of IRS1/2. The magnified signaling activity under those chronic inflammatory conditions also causes overt negative interference on the insulin receptor signaling by the actions of protein tyrosine phosphatases such as PTP1B [3] and the serine/threonine phosphatases PHLPP [4] and PP2A [5]. This overall inability of the IR to transduce signal despite normal binding of insulin is characterized biochemically as insulin resistance. Thus, chronic systemic inflammatory states indirectly results in inhibition of insulin receptor signaling as a result of the biochemical crosstalk between these pathways due to the utilization of common signaling intermediates. SOCS3 specifically is part of a multi-component cullin ring ligase (CRL) protein complex with elongin, Cullin5, RBX, and ubiquitin transferase (E2). The CRL complex requires neddylation of Cullin5 by NEDD8 to function as an E3 ligase. Inhibiting neddylation of Cullin5 prevents it from mediating the ubiquitination of IRS1 and therefore preserving insulin receptor signaling capability [6].
The present disclosure thus provides a platform strategy for the integration of diverse forms of insulin, insulin-like proteins and distinct small molecules as single compounds to specifically target the insulin receptor. Targeting of major insulin-responsive cells and tissues with the compounds of the disclosure, or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, restores insulin sensitivity and function in order to treat conditions were insulin resistance occurs. In some embodiments, the compound of the disclosure, or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, comprises a neddylation inhibitor, preventing neddylation of Cullin5, thus, maintaining IRS-1 function. Also, IRS-1 has been shown to be ubiquitinated by a distinct CRL complex composed of Cullin7, ROC1 and SKP1-FBW8 resulting in it's degradation. This is part of a negative feedback loop initiated by insulin receptor signaling and intermediated by the activity of the mTORC1 pathway and serves to limit PI3K and AKT activation [7]. Thus, this pathway can also be restored by the use of the insulin-nedd8 inhibitor single drug platform.
Utilizing insulin and insulin-like proteins and homologs covalently bound to drugs other than nedd8 inhibitors, such as PTP1B inhibitors, PP2A inhibitors, PHLPP inhibitors and AKT activators [8] the present disclosure also provides new treatments for treating insulin resistance caused by biochemical events other than IRS-1 degradation.

The terms “peptide,” “polypeptide,” and “protein” may be used interchangeably herein, and may refer to a polymeric form of amino acids of any length, which can include coded and non-coded amino acids, chemically or biochemically modified or derivatized amino acids, full-length polypeptides, fragments of polypeptides, variants of polypeptides, truncated polypeptides, fusion polypeptides, or polypeptides having modified peptide backbones. The polypeptides disclosed herein may also be variants differing from a specifically recited “reference” polypeptide (e.g., a wild-type polypeptide) by amino acid insertions, deletions, mutations, and/or substitutions.
In some embodiments, conservative substitutions may be made in the amino acid sequence of a polypeptide without disrupting the three-dimensional structure or function of the polypeptide. Conservative substitutions may be accomplished by the skilled artisan by substituting amino acids with similar hydrophobicity, polarity, and R-chain length for one another. Additionally, by comparing aligned sequences of homologous proteins from different species, conservative substitutions may be identified by locating amino acid residues that have been mutated between species without altering the basic functions of the encoded proteins. The term “conservative amino acid substitution” may refer to the interchangeability in proteins of amino acid residues having similar side chains. For example, a group of amino acids having aliphatic side chains consists of glycine, alanine, valine, leucine, and isoleucine; a group of amino acids having aliphatic-hydroxyl side chains consists of serine and threonine; a group of amino acids having amide containing side chains consisting of asparagine and glutamine; a group of amino acids having aromatic side chains consists of phenylalanine, tyrosine, and tryptophan; a group of amino acids having basic side chains consists of lysine, arginine, and histidine; a group of amino acids having acidic side chains consists of glutamate and aspartate; and a group of amino acids having sulfur containing side chains consists of cysteine and methionine. Exemplary conservative amino acid substitution groups are: valine-leucine-isoleucine, phenylalanine-tyrosine, lysine-arginine, alanine-valine, and asparagine-glutamine.
A polypeptide has a certain percent “sequence identity” to another polypeptide, meaning that, when aligned, that percentage of bases or amino acids are the same, and in the same relative position, when comparing the two sequences. Sequence identity can be determined in a number of different manners. To determine sequence identity, sequences can be aligned using various methods and computer programs (e.g., BLAST, T-COFFEE, MUSCLE, MAFFT, etc.), available over the world wide web at sites including ncbi.nlm.nili.gov/BLAST,ebi.ac.uk/Tools/msa/tcoffee/ebi.ac.uk/Tools/msa/muscle/mafft.cbrc.jp/alignment/software/. See, e.g., Altschul et al. (1990), J. Mol. Biol. 215:403-10.

X1 is a biologically active polypeptide, e.g., a polypeptide exerting its own biological effect on specified targets, or a hormone. Cytokines, growth factors (GF), and hormones are all chemical messengers that mediate intercellular communication. The regulation of cellular and nuclear functions by cytokines, growth factors, and hormones is initiated through the activation of cell surface receptors (Rc). All receptors generally have two main components: 1) a ligand-binding domain that ensures ligand specificity and 2) an effector domain that initiates the generation of the biological response upon ligand binding. The activated receptor may then interact with other cellular components to complete the signal transduction process. Among such proteins are insulin, insulin-like proteins and homologs.
Many insulin, insulin-like proteins and homologs have been produced and clinically tested (see table I) and each allows for the conjugation of a linker to a distinct amino acid site available to attach the therapeutic compound payload. Cysteine residues or lysine residues in these proteins are chemically available for conjugation. There is only one Lys residue identified in the first amino acid chain which is available for conjugation (
Insulin, insulin-like proteins and homologs used in the disclosure are detailed in Table 4. The insulin and variants of Table 4 may exhibit increased half-life and solubility compared to wild-type human insulin. These proteins retain high affinity for the insulin receptor even after conjugation with a linker and a therapeutic compound.

Hormones are any member of a class of signaling molecules produced by glands in, multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behavior. Hormones have diverse chemical structures, mainly of three classes: eicosanoids, steroids, and amino acid/protein derivatives (amines, peptides, and proteins). The glands that secrete hormones comprise the endocrine signaling system. The term hormone is sometimes extended to include chemicals produced by cells that affect the same cell (autocrine or intracrine signaling) or nearby cells (paracrine signaling).
Hormones are used to communicate between organs and tissues for physiological regulation and behavioral activities, such as digestion, metabolism, respiration, tissue function, sensory perception, sleep, excretion, lactation, stress, growth and development, movement, reproduction, and mood. Hormones affect distant cells by binding to specific receptor proteins in the target cell resulting in a change in cell function. When a hormone binds to the receptor, it results in the activation of a signal transduction pathway that typically activates gene transcription resulting in increased expression of target proteins; non-genomic effects are more rapid and can be synergistic with genomic effects. Amino acid-based hormones (amines and peptide or protein hormones) are water-soluble and act on the surface of target cells via second messengers; steroid hormones, being lipid-soluble, move through the plasma membranes of target cells (both cytoplasmic and nuclear) to act within their nuclei.

The disclosure is directed to compounds as described herein and pharmaceutically acceptable salts, solvates, hydrates, isomers, or tautomers thereof. The use of the terms “salt,” “hydrate,” “solvate,” and the like, is intended to equally apply to the salt, hydrate, or solvate of isomers, tautomers, or racemates of the disclosed compounds.
It should be understood that all isomeric forms are included within the present disclosure, including mixtures thereof. The term “isomer” may refer to compounds that have the same composition and molecular weight but differ in physical and/or chemical properties. The structural difference may be in constitution (geometric or positional isomers) or in the ability to rotate the plane of polarized light (stereoisomers). With regard to stereoisomers, the compounds of the disclosure may have one or more asymmetric carbon atom and may occur as racemates, racemic mixtures and as individual enantiomers or diastereomers. Individual isomers of the compounds of the disclosure may, for example, be substantially free of other isomers, or may be admixed, for example, as racemates or with all other, or other selected, isomers. If the compound contains a double bond, the substituent may be in the E or Z configuration or cis or trans configuration or mixtures of any of the foregoing. Disclosed assay results may reflect the data collected for the racemic form, the enantiomerically pure form, or any other form in terms of stereochemistry or constitution (e.g., geometric or positional isomers).
The compounds of the disclosure may contain asymmetric or chiral centers, and, therefore, exist in different stereoisomeric forms. The term “stereoisomers” may refer to the set of compounds which have the same number and type of atoms and share the same bond connectivity between those atoms, but differ in three dimensional structure. The term “stereoisomer” may refer to any member of this set of compounds. For instance, a stereoisomer may be an enantiomer or a diastereomer. It is intended that all stereoisomeric forms of the compounds of the disclosure as well as mixtures thereof, including racemic mixtures, form part of the present disclosure.
The term “enantiomers” may refer to a pair of stereoisomers which are non-superimposable mirror images of one another. The term “enantiomer” may refer to a single member of this pair of stereoisomers. The term “racemic” may refer to a 1:1 mixture of a pair of enantiomers. Each compound herein disclosed may include all the enantiomers (which may exist even in the absence of asymmetric carbons) that conform to the general structure of the compound, unless the stereochemistry is specifically indicated. The compounds may be in a racemic or enantiomerically pure form, or any other form in terms of stereochemistry. The chiral centers of the present disclosure may have the S or R configuration as defined by the IUPAC 1974 Recommendations. In some examples presented, the synthetic route may produce a single enantiomer or a mixture of enantiomers. In some embodiments of the disclosure, the compounds of the disclosure are enantiomers. In some embodiments, the compounds of the disclosure are the (S)-enantiomer. In other embodiments, the compounds of the disclosure are the (R)-enantiomer. In yet other embodiments, the compounds of the disclosure may be (+) or (−) enantiomers.
The term “diastereomers” may refer to the set of stereoisomers which cannot be made superimposable by rotation around single bonds. For example, cis- and trans-double bonds, endo- and exo-substitution on bicyclic ring systems, and compounds containing multiple stereogenic centers with different relative configurations may be considered to be diastereomers. The term “diastereomer” may refer to any member of this set of compounds. In some examples presented, the synthetic route may produce a single diastereomer or a mixture of diastereomers. The disclosure may include diastereomers of the compounds described herein.
In some embodiments, pharmaceutical compositions of the disclosure may be enriched to provide predominantly one enantiomer of a compound described herein. An enantiomerically enriched mixture may comprise, for example, at least 60 mol percent of one enantiomer, or more preferably at least 75, at least 80, at least 85, at least 90, at least 95, at least 96, at least 97, at least 98, at least 99, at least 99.5 or even 100 mol percent. In some embodiments, the compound described herein enriched in one enantiomer may be substantially free of the other enantiomer, wherein substantially free may mean that the substance in question makes up less than 10%, or less than 5%, or less than 4%, or less than 3%, or less than 2%, or less than 1% as compared to the amount of the other enantiomer, e.g., in the pharmaceutical composition or compound mixture. For example, if a pharmaceutical composition or compound mixture contains 98 grams of a first enantiomer and 2 grams of a second enantiomer, it would be said to contain 98 mol percent of the first enantiomer and only 2 mol percent of the second enantiomer.
In some embodiments, the pharmaceutical compositions of the disclosure may be enriched to provide predominantly one diastereomer of a compound disclosed herein. A diastereomerically enriched mixture may comprise, for example, at least 60 mol percent of one diastereomer, or more preferably at least 75, at least 80, at least 85, at least 90, at least 95, at least 96, at least 97, at least 98, at least 99, at least 99.5, or even 100 mol percent. In some embodiments, the compound described herein enriched in one diastereomer may be substantially free of other diastereomers, wherein substantially free may mean that the substance in question makes up less than 10%, or less than 5%, or less than 4%, or less than 3%, or less than 2%, or less than 1% as compared to the amount of other disastereomers, e.g., in the pharmaceutical composition or compound mixture.
Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods well known to those skilled in the art, such as, for example, by chromatography and/or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers. Enantiomers can also be separated by use of a chiral HPLC column.
Also, some of the compounds of the disclosure may be atropisomers or rotameric forms and are considered as part of this disclosure.
Compounds of the disclosure may exist in their tautomeric form (for example, as an amide or imino ether). All such tautomeric forms are contemplated herein as part of the present disclosure.
In some embodiments, the present disclosure provides compounds of Formula (I), (II), or (III), or pharmaceutically acceptable salts, solvates, hydrates, or tautomers thereof, or pharmaceutical compositions comprising the compounds, or pharmaceutically acceptable salts, solvates, hydrates, or tautomers thereof, wherein the isomeric form and/or stereochemistry is not determined. All isomers, including stereoisomers, of Formula (I), (II), or (III), or pharmaceutically acceptable salts, solvates, hydrates, or tautomers thereof, are hereby included in the disclosure.

“Pharmaceutically acceptable base addition salt” may refer to those salts that retain the biological effectiveness and properties of the free acids, which are not biologically or otherwise undesirable. These salts may be prepared from addition of an inorganic base or an organic base to the free acid. Salts derived from inorganic bases may include, but are not limited to, the sodium, potassium, lithium, ammonium, calcium, magnesium, iron, zinc, copper, manganese, aluminum salts and the like.

Examples of suitable solvents include, but are not limited to, water, MeOH, EtOH, and AcOH. Solvates wherein water is the solvent molecule are typically referred to as hydrates. Hydrates may include compositions containing stoichiometric amounts of water, as well as compositions containing variable amounts of water.
The compounds described herein further include all pharmaceutically acceptable isotopically labeled compounds. An “isotopically” or “radio-labeled” compound may be a compound where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (i.e., naturally occurring). For example, in some embodiments, in the compounds described herein hydrogen atoms are replaced or substituted by one or more deuterium or tritium. Certain isotopically labeled compounds of this disclosure, for example, those incorporating a radioactive isotope, may be useful in drug and/or substrate tissue distribution studies. The radioactive isotopes tritium, i.e., 3H, and carbon 14, i.e., 14C, may be particularly useful for this purpose in view of their ease of incorporation and ready means of detection. Substitution with heavier isotopes such as deuterium, i.e., 2H, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. Suitable isotopes that may be incorporated in compounds described herein include but are not limited to 2H (also written as D for deuterium), 3H (also written as T for tritium), 11C, 13C, 14C, 13N, 15N, 15O, 17O, 18O, 18F, 35S, 36Cl, 82Br, 75Br, 76Br, 77Br, 123I, 124I, 125I, and 131I. Substitution with positron emitting isotopes, such as 11C, 18F, 15O, and 13N, can be useful in Positron Emission Topography (PET) studies.
The compounds of the present disclosure (e.g., a compound of Formula (I), (II), or (III)), or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, may be made by a variety of methods, including standard chemistry. Suitable synthetic routes are depicted in the schemes given herein.
The compounds disclosed herein (e.g., a compound of Formula (I), (II), or (III)), or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, may be prepared by methods known in the art of organic synthesis as set forth in part by the following synthetic schemes. In the schemes described herein, it is well understood that protecting groups for sensitive or reactive groups are employed where necessary in accordance with general principles or chemistry. Protecting groups are manipulated according to standard methods of organic synthesis (T. W. Greene and P. G. M. Wuts, “Protective Groups in Organic Synthesis,” Third edition, Wiley, New York 1999). These groups are removed at a convenient stage of the compound synthesis using methods that are readily apparent to those skilled in the art. The selection processes, as well as the reaction conditions and order of their execution, shall be consistent with the preparation of compounds of disclosed herein (e.g., a compound of Formula (I), (II), or (III)), or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof.
Those skilled in the art will recognize if a stereocenter exists in the compounds disclosed herein (e.g., a compound of Formula (I), (II), or (III)), or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof. Compounds disclosed herein can exist as enantiomeric or diastereomeric stereoisomers. Accordingly, the present disclosure includes all possible stereoisomers (unless specified in the synthesis) and includes not only racemic compounds but the individual enantiomers and/or diastereomers as well. When a compound is desired as a single enantiomer or diastereomer, it may be obtained by stereospecific synthesis or by resolution of the final product or any convenient intermediate. For example, enantiomerically pure compounds of of the disclosure can be prepared using enantiomerically pure chiral building blocks. Alternatively, racemic mixtures of the final compounds or a racemic mixture of an advanced intermediate can be subjected to chiral purification as described herein to deliver the desired enantiomerically pure intermediates or final compounds. In the instances where an advanced intermediate is purified into its individual enantiomers, each individual enantiomer can be carried on separately to deliver the final enantiomerically pure compounds of of the disclosure. Resolution of the final product, an intermediate, or a starting material may be affected by any suitable method known in the art. See, for example, “Stereochemistry of Organic Compounds,” by E. L. Eliel, S. H. Wilen, and L. N. Mander (Wiley-Interscience, 1994).
The compounds described herein (e.g., a compound of Formula (I), (II), or (III)), or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, may be made from commercially available starting materials or synthesized using known organic, inorganic, and/or enzymatic processes.
In certain aspects, such as for the production of bioactive polypeptides or hormones utilized in the disclosure or for evaluating the biological activities of the compounds of the disclosure (e.g., a compound of Formula (I), (II), or (III)), or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, the practice of the present disclosure will employ, unless otherwise indicated, conventional techniques of molecular biology (including recombinant techniques), microbiology, cell biology, biochemistry, and immunology, which are within the skill of the art. Such techniques are explained fully in the literature: “Molecular Cloning: A Laboratory Manual,” second edition (Sambrook et al., 1989); “Oligonucleotide Synthesis” (M. J. Gait, ed., 1984); “Animal Cell Culture” (R. I. Freshney, ed., 1987); “Methods in Enzymology” (Academic Press, Inc.); “Current Protocols in Molecular Biology” (F. M. Ausubel et al., eds., 1987, and periodic updates); “PCR: The Polymerase Chain Reaction,” (Mullis et al., eds., 1994). Singleton et al., Dictionary of Microbiology and Molecular Biology 2nd ed., J. Wiley & Sons (New York, N.Y. 1994), and March, Advanced Organic Chemistry Reactions, Mechanisms and Structure 4th ed., John Wiley & Sons (New York, N.Y. 1992), provide one skilled in the art with a general guide to many of the terms used in the present application.
In some cases, the dipeptide based linkers described herein have been utilized as cleavable groups for the delivery of therapeutic compound payloads in other constructs to cells or tissue of interest. Several combinations of dipeptides have been utilized, with the valine-citrulline (Val-Cit) and valine-alanine (Val-Ala) as the most successful combinations. [13,14,15,16,17] The synthetic pathway leading to the synthesis of Val-Cit and Val-Ala dipeptides are very similar and shown in the Scheme 1 herein.
The amino group of Valine is initially protected with a Fluorenylmethyloxycarbonyl (Fmoc) group, followed by the activation of the carboxylic acid group with N-Hydroxysuccinimide (NETS) to form compound 3. Compound 3 can then be reacted with either citrulline or alanine in an aqueous solution of NaHCO3 with D1VIF and THF present to ensure proper solubility. The resulting compound 4 can be coupled to para-aminobenzylalcohol group (PABOH) using N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline (“EEDQ”), which leads to the formation of compound 5.[18] Removal of the Fmoc group may be carried out with diethyl amine in D1VIF at room temperature to give amino-alcohol 6.
As shown in Scheme 2, glycols of various lengths may be reacted with a catalytic amount of sodium metal under anhydrous condition to promote the addition to tert-butyl acrylate for the Michael Addition product 9.[19] Next, maleimide can be reacted with glycol under Mitsunobu conditions to produce compound 10 in good yields. [20] Deprotection of the tert-butyl ester with trifluoroacetic acid may be followed by the esterification under Steglich conditions with DIC and pentafluorophenol to give compound 12.[21] An alternative approach to the formation of the pentafluorophenol ester is the reaction of the carboxylic acid with perfluorophenyl 2,2,2-trifluoroacetate (PPTA) in the presence of pyridine in DMF.[22] The conditions are very mild and produce very good yields of the pentafluoroester. NETS has also been frequently been used to form the activated ester. These methods allow for the introduction of halogenated maleimides as well as the thiophenol derivatives.
Scheme 3 shows the synthesis of a non-cleavable linker using the maleiminde as the key group to attach to a cysteine residue. With the incorporation of halogens on the maleimide, multiple cysteine residues or sulfides resulting from the cleavage of a disulfide bond can react at both halogenated positions. The synthesis of this versatile linker begins with the condensation of maleic anhydride (with or without halogens) with 3-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)propanoic acid in refluxing acid to give a near quantitative yield of compound 15. [23] Carboxylic acid 15 can be converted to the pentafluoro ester through either a DCC coupling in ethyl acetate or using perfluorophenyl 2,2,2-trifluoroacetate (PPTA) in the presence of pyridine in DMF to give compound 16 [22]. The pentafluoro ester 16 is very amenable to displacement by amines under mild conditions to give a non-cleavable drug conjugate, where the maleimide moiety reacts under mild conditions with available cysteine residues and n is 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10.
To improve the stability of the heterobifunctional cross-linking reagent, 6-maleimidohexanoic acid pentafluorophenyl ester (Mal-PEGn-PFP, where n is defined below) may be prepared as a substitute for the more popular 6-maleimidohexanoic acid N-hydroxysuccinimide ester (MHSu).[24] Mal-PEGn-PFP is prepared in two steps in very good yields to give compounds 12 and 16 as shown herein in Schemes 2 and 3. [14 and 15] Subsequent reaction of compound 6 with Mal-PEG3-PFP and DBMal-PEG3-PFP in DMF provided very good yields of compounds 17 and 18 shown in Scheme 4.
As shown in Scheme 5, compound 17 can be activated using two different methods to facilitate the attachment of various therapeutic compound as payloads before bio-conjugation to either Cys or Lys residues of biologically active polypeptides, such as Insulin polypeptides. Initially, Bis(4-nitrophenyl) carbonate was reacted with compound 7 in the presence of N,N-Diisopropylethylamine and DMF to give carbonate 12. [24] Alternatively, N,N-disuccinimidyl carbonate can be used in a similar fashion under the same conditions. Both the p-Nitrophenol and the N-Hydroxysuccinimde function as leaving groups in the subsequent reaction. In a similar fashion, the mesylate 20 can be generated from the benzyl alcohol using Ms2O in dichloromethane.
Nitro-carbonate 19 can react with the therapeutic compound to form carbonyl compound 21 which can take the form of a carbamate or a carbonate, depending on whether the reactive site on the therapeutic compound is an amine or an alcohol. When the therapeutic compound possesses a tertiary or heteroaryl amine, it can be reacted with compound 20 to generate a quaternary amine attachment to deliver the payload. [25]
Below in Scheme 7, benzyl alcohol 5 was converted to a Mesylate (or similar leaving group) and subsequently replaced by the drug to form a quaternary ammonium bond with the linker. The mesylate (and potentially the triflate) offer an improvement in reactivity over the Iodo or Bromo substituted benzyl group. To finish functionalizing the PDC, the Fmoc group was deprotected and attach to a linker capable of reacting with Lysine residues on the protein as shown in Scheme 8.
Scheme 8 shows the final deprotection of the Fmoc group of Valine, making the primary amine available for reaction with the Bis-PEG3-PFP ester to generate compound 27. The alternative to this one step conversion is reacting compound 25 with Acid-PEG3-PFP-Ester to generate the carboxylic acid 26. The carboxylic acid can then be converted to the PFP ester using PPTA in DMF with pyridine as a solvent.
The Glucuronide scaffold has been utilized in assisting the transport of active biological agents and therapeutic compound payloads to a specific location. [26,27,28,29,30] As shown in Scheme 1, the synthesis of the transport molecule may be initiated with the commercially available (2S,3R,4S,5S,6S)-6-(methoxycarbonyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate) undergoing a mild bromide substitution of the acetate group through the reaction of compound 28 with HBr in acetic acid to form compound 29. The bromide may be replaced by reacting 4-hydroxy-3-nitrobenzaldehyde with silver oxide in acetonitrile resulting in the formation of compound 30. Reduction of the formal group with sodium borohydride in methanol to give compound 31, may be followed by the reduction of the nitro group by palladium hydroxide to give the amino alcohol 32.
Commercially available Fmoc-B-Alanine was sonicated with thionyl chloride in dichloromethane at room temperature to form the resulting (9H-fluoren-9-yl)methyl (3-chloro-3-oxopropyl)carbamate or compound 34.
As shown in Scheme 11, the amino group of compound 32 can be selectively reacted with (9H-fluoren-9-yl)methyl (3-chloro-3-oxopropyl)carbamate followed by the formation of mesylate intermediate 35. Mesylate 35 can be reacted with the tertiary amine of the therapeutic compound to form a stable bio-reversible quaternary ammonium linkage of compound 36. Deprotection of the acetate groups with LiOH, which also lead to the removal of the Fmoc group gives compound 37.
As shown in Schemes 12 and 13, compound 37 can be functionalized to react with either the Cys or Lys residues on biologically active polypeptides, such as Insulin polypeptides. For a bioconjugation to the Cys residue, the free amine on compound 37 can be reacted with the heterobifunctional cross-linking reagent Mal-PEGS-PFP to react with a single Cysteine of the protein or reacted with DBMal-PEG3-PFP to re-bridge the reduced disulfide to maintain the structural integrity of the protein. For the bioconjugation to the Insulin Lys residue, the free amine 37 can be reacted with Acid-PEGS-PFP ester to give the acid 40, followed by the conversion to the PFP ester 41 using PPTA with pyridine in a solution of DMF. Alternatively, the PFP ester 41 can be formed directly from compound 36 through a reaction with Bis-PEG3-PFP ester shown in Scheme 7.
Attachment of the payload to the drug conjugate often requires a functional linker with very good solubility properties as well as serum stability. Glycols may be used in this capacity. Below in schemes 14, 15, and 16, there are several approaches for the synthesis of glycol side chains that allow for easy attachment of both the payload as well as the conjugate linkers. In Scheme 5, an ethylene glycol may be reacted with Tosyl chloride to produce the Bis-Tosylate. The Bis-Tosylate may then be reacted with the Bis-tert-butyl carbamate to form compound 44. Subsequent reaction with LiBr results in the bromide substitution of the Tosylate to give compound 45.[31] In Schemes 14, 15, and 16, n is 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10.
Glycol 46 in Scheme 15 has a terminal chloride, which is available for substitution. Sodium azide may be used to displace the chloride atom and the azide was then reduced with triphenylphosphine followed by protection of the amine with Boc anhydride to give compound 48. The hydroxyl group may then finally be converted to a bromide using triphenylphosphine and carbon tetrabromide to give compound 49.[32]
In Scheme 16, the di-iodinated glycol is reacted with the Bis-Boc-carbamate to produce the Bis-Boc protected amino-iodo-glycol 51.
Hypothetical examples are disclosed below to illustrate the invention. Persons skilled in the art will recognize many different variations of these hypotheticals based on the disclosure in this document and known prior art. All variations are intended to be within the scope of this invention. Therefore, the examples disclosed are not intended to limit the scope of the claims. Animal Distribution into Treatment Groups: Mice were distributed into treatment groups by body weight so that there is no significant difference between the means across groups.
Intraperitoneal (IP) Dosing: A 27 g ½″ gauge needle is used for injection. Injection volume for the study is 5 ml/kg per injection. Restrain the mouse and identify the injection location which is above or equal to the top of the hips and below the middle of the abdomen, generally just to the right of the midline.
Glucose Tolerance Test (ipGTT): Mice are weighed and transferred to individual clean cages that provide water and bedding only (no food pellets) for a fast of 6 hours.
A dextrose (glucose) solution is prepared aseptically for injection by diluting sterile 50% dextrose with sterile 0.9% saline for a 20% working stock. The working concentration is 0.2 g/mL (20%) and the dose is 2 g/kg body weight. The volume of the dextrose solution needed for each individual mouse is calculated and individually labeled insulin syringes (27-31 G, 5/16″ length) are filled with the appropriate volume of solution for each mouse. The mouse is restrained by hand and the tip of the tail is cut using sterile surgical scissors. A drop of blood (˜5 μL) from the tail is placed on the glucose test strip and the baseline blood glucose level is measured and recorded using a handheld blood glucose meter that has been calibrated prior to experimental testing.
Dextrose is administered by means of an intra-peritoneal injection immediately after the baseline measurement is taken. Additional glucose measurements are repeated at 15, 30, 60, 90 and 120 minutes following the IP dextrose injection.
Mice were divided into four groups at ten mice each and each mouse was dosed daily for five days with Compound B-55.
Group 1 received Vehicle Control. Group 2 received the positive control, Pioglitazone at 30 mg/Kg. Group 3 received Compound B-55 at 0.3 IU/Kg. Group 4 received Compound B-55 at 0.6 IU/Kg.
The results of this test can be found in table 7 Below:
As shown is in table 7 above, A highly significant difference in glucose tolerance was observed between treatment groups: vehicle<Compound B-55<Pioglitazone.
