Description
[0001] THERAPEUTIC COMPOUNDS AND THEIR USE
[0002] TECHNICAL FIELD
[0003] The present invention pertains generally to the field of therapeutic compounds.
[0004] More specifically the present invention pertains to certain biarylamide compounds (also referred to herein as “BAA compounds”) which inhibit Protein Kinase, Membrane Associated Tyrosine / Threonine 1 (PKMYT1). The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit PKMYT1 kinase; to treat disorders (e.g., diseases) that are ameliorated by the inhibition of PKMYT 1 kinase; to treat a proliferative disorder, cancer, etc.
[0005] BACKGROUND
[0006] Publications are cited herein in order to more fully describe the state of the art to which the invention pertains. Each of these references is incorporated herein by reference in its entirety into the present disclosure, to the same extent as if each individual reference was specifically and individually indicated to be incorporated by reference.
[0007] Throughout this specification, including the claims which follow, unless the context requires otherwise, the word “comprise,” and variations such as “comprises” and “comprising,” will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
[0008] It must be noted that, as used in the specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a pharmaceutical carrier” includes mixtures of two or more such carriers, and the like.
[0009] Ranges are often expressed herein as from “about” one particular value, and / or to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value and / or to the other particular value. Similarly, when values are expressed as approximations, by the use of the antecedent “about,” it will be understood that the particular value forms another embodiment.
[0010] This disclosure includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art. Protein kinase, membrane-associated
[0011] A key hallmark of cancer is that cancer cells override the cell cycle controls that prevent commitment to division until the appropriate conditions have been fulfilled. Once the conditions are right, cells are pushed through a decision point called the “restriction point” into the cell division cycle by the activity of Cdk4 / 6-Cyclin D complexes. Once through this point of no return, cells activate Cdk2-Cyclin E in order to drive the duplication of the DNA that will be segregated into two daughter cells later in the cell cycle (by Cdk1-Cyclin B).
[0012] In order to be able to proliferate illegitimately, cancer cells inappropriately boost the kinase activity of Cdk4 / 6-Cyclin D complexes or bypass the requirement for Cdk4 / 6-Cyclin D activation, by activating the downstream Cdk2-Cyclin E complex, independently of any input from Cdk4 / 6-Cyclin D. Implementation of either of these two approaches enable cancers to evade the normal controls that maintain balanced growth and homeostasis within the body. Consequently, cancer proliferation is unregulated.
[0013] Drugs that inhibit the Cdk4 / 6-Cyclin D complexes are having a major therapeutic impact in hormone responsive HER2 negative breast cancer (HER2- ER+) and are being trialled in a variety of other cancers.
[0014] In contrast, counteracting Cdk2-Cyclin E hyperactivation was considered to be undruggable until a recent study reported that a WEE1 family kinase called PKMYT1 is only essential when Cyclin E levels are abnormally high (Gallo et al., 2022). Importantly, they found that PKMYT1 ablation does not kill normal cells.
[0015] The same study showed that PKMYT1 ablation is synthetically lethal in the presence of Cyclin E (CCNE1) over-expression; CCNE1 overexpression drives the transcription of Cyclin B to elevate Cyclin B levels to generate so much Cdk1 -Cyclin B that all the available Cdk1 inhibitory activity is required to restrain this Cdk1-CyclinB and prevent a catastrophic mitosis. Thus, CCNE1 overproduction generates a dependency on PKMYT1.
[0016] FBXW7 is a gene which encodes an E3 ligase that degrades Cyclin E. FBXW7 loss, has also been found to be synthetically lethal in the presence of PKMYT1 inhibition (Durocher et al., 2021), demonstrating that PKMYT1 drugs hold potential as first line therapy in several cancers. CCNE1 amplification has been reported in several cancer types including endometrial, ovarian, breast and gastric, ranging in frequency from 5-40%. CCNE1 amplification and / or FBXW7 mutations occur in >60% of uterine carcinosarcomas, >20% of uterine cancers, -20% of ovarian cancers, -18% of stomach cancers, -14% of colorectal cancer, -12% of bladder cancers, 11.5% of oesophageal cancers, -11 % of cervical cancers, 7.5% of sarcomas and -7% of lung squamous cancers (Durocher et al., 2021). CCNE1 also occurs at lower levels in other cancers such as adenoid cystic carcinoma, pancreatic cancer, mesothelioma, lung adenocarcinoma, head & neck cancers, difuse large B-cells lymphoma, liver cancers and others (Gorski et al., 2020). Moreover, CCNE1 over expressing ovarian cancers are a subset of the 50% that are recombination proficient so do not benefit from PARP inhibitors (Gorski et al., 2020), highlighting the unmet need in these indications.
[0017] CCNE1 amplification is observed in the more aggressive subtypes including uterine carcinosarcoma (UCS; -40%), uterine serous carcinoma (USC; - 25%), high-grade serous ovarian carcinoma (HGSOC; -20%), and triple-negative breast cancer (TNBC; -8%). CCNE1 overexpression in tumor biopsies is linked to lower overall survival compared to patients with normal Cyclin E1 levels. HGSOC patients with CCNE1 over-expression have a lower response rate to cisplatin, the current standard of care.
[0018] Similarly, FBXW7 '\s frequently mutated in several cancer types including uterine carcinosarcoma, endometrial, colorectal, cervical, bladder, head & neck, gastric, cancers and lung squamous cells carcinoma ranging in frequency from 5-39%. Like CCNE1 overexpression, FBXW7 driver mutations are observed in the more aggressive subtypes of endometrial cancer including UCS and USC.
[0019] Elevation of Cdk2-Cyclin E activity, via a variety of means, is also associated with resistance to Cdk4 / 6 inhibitors (Fassl et al., 2022); this suggests that PKMYT1 inhibition will also constitute a robust second line treatment in the cohort of HER2- ER+ breast cancer patients treated with Cdk4 / 6 inhibitors who generally develop resistance after around 2 years of therapy, and in CDK4 / 6 inhibitor resistant TP53 mutant ER+ breast cancer (Chen et al, 2024).
[0020] A recently discovered inhibitor of PKMYT1, RP-6306 (Szychowski et al., 2022), has shown efficacy in vivo in models of breast and ovarian cancers overexpressing CCNE1, as well as in a pancreatic PDX model with increased expression of CCNE1, alone or in combination with Gemcitabine (Gallo et al., 2022).
[0021] It has been claimed that synthetic lethality occurs in cancer cells between PKMYT1 inhibition and deficiency in protein phosphatase 2 (PP2A), in particular, regulatory subunit B alpha (PPP2R2A) (Yost et al., 2021). PPP2R2A inactivation is present in 15% of prostate adenocarcinoma, and at >5% in Ovarian serous cystadenocarcinoma, rectum adenocarcinoma, Bladder Urothelial Carcinoma, colorectal adenocarcinoma, breast invasive carcinoma, Uterine Corpus Endometrial Carcinoma, Uterine Carcinosarcoma, Liver hepatocellular carcinoma, Lung squamous cell carcinoma, lung adenocarcinoma.
[0022] Replication stress induced by genetic alterations creates a synthetic lethal relationship between these specific alterations and PKMYT1 inhibition. RAS mutations, in particular in combination with TP53 mutations, are drivers of replication stress, and as such sensitises mutant RAS cancer cells to PKMYT1 inhibition. KRAS is mutated in about 11.6% of all cancers. KRAS mutations are most common in pancreatic ductal adenocarcinoma (PDAC) (-82% of patients), colorectal cancers (CRC) (-38%), non-small cells lung cancers (NSCLC) (-21%). In addition, KRAS mutations are found in choloangiocarcinoma, uterine endometrial carcinoma, testicular germ cell cancer and cervical squamous cell carcinoma, with a mutation frequency of about 12.7%, 14.1%, 11.7%, and 4.3%, respectively. NRAS is mutated in 5% of CRC, 15-20% of melanomas, and 15-20 of haematologic cancers such as acute myeloid leukemia (AML).
[0023] PKMYT1 is a cell cycle regulating kinase, part of the WEE1 family of kinases that includes WEE1 and WEE2. WEE2 is restricted to gonads as it regulates meiosis. In contrast both PKMYT1 and WEE1 are ubiquitously expressed. PKMYT1 is localized predominantly in the endoplasmic reticulum and Golgi complex, while WEE1 is predominantly a nuclear protein. PKMYT1 is involved in the negative regulation of the CDK1-Cyclin B complex which promotes the progression of cells from G2-phase into the mitotic phase (M-phase) of the cell cycle. The biology of Cyclin E overproduction generates a need for the otherwise non-essential PKMYT1. Cyclin E accumulation boosts the transcription of cyclin B1; the potential to form active Cdk1-Cyclin B is greatly enhanced by CCNE1 overexpression. This places a far greater demand upon the Cdk1-Cyclin B inhibitory activity of WEE1 and PKMYT1 such that PKMYT1 becomes essential. Furthermore, CCNE1 overproduction stimulates abnormally high levels of DNA replication that deplete the nucleotide pool and generate DNA damage (Jones et al, 2013). The DNA damage generated by Cyclin E accumulation is not in itself lethal because cells have G2 / M checkpoints that restrain commitment to genome segregation in mitosis until all damage is repaired. These checkpoint pathways boost the activity of the Wee1 family kinases WEE1 and PKMYT1 , which restrain division by phosphorylating Cdk1 kinase to block Cdk1 -Cyclin B activity. While damage persists, WEE1 and PKMYT1 activities remain high and cells cannot divide. Thus, WEE1 or PKMYT1 inhibition kills damaged cells by forcing them to divide when their DNA is still damaged and / or un-replicated. This places higher demands upon the ability of WEE1 and PKMYT1 to restrain CDK1-Cyclin B activity to maintain cell viability.
[0024] PKMYT 1 can be removed from untransformed cells because the requirement for restraint of CDK1-CyclinB1 activity can be met by WEE1 alone. It is only when abnormally high levels of DNA damage generates a greater need for CDK1 cyclin B inhibition that PKMYTTs activities become essential.
[0025] The WEE1 inhibitor adavosertib has progressed to clinical trials in a number of solid tumours (clinicaltrials.gov) but presented significant toxicity. WEE1 inhibition toxicity most likely arises from its ability to inhibit both CDK2 and CDK1 complexes. CDK2-Cyclin E and CDK2-Cyclin A regulate the initiation and progression through DNA replication. Release of excessive levels of CDK2-Cyclin activities will generate DNA damage in a phenomenon known as oncogene induced replicative senescence. PKMYT1 inhibition is unlikely to display similar S phase toxicity, because, unlike WEE1 , it phosphorylates CDK1 (Booher et al., 1997; Liu et al., 1997).
[0026] Collectively, the dependency on PKMYT1 that is generated by excessive Cdk2-Cyclin E activity in cancer cells and the markedly reduced toxicity in normal tissues arising from its restriction to CDK1 regulation make PKMYT1 is a highly attractive target for inhibition for patients whose tumours proliferate inappropriately because of enhanced Cdk2-Cyclin E activity. Overexpression of PKMYT1 has been observed in various cancers (compared to normal tissues), including Lung squamous cell carcinoma, lung adenocarcinoma, Uterine Corpus Endometrial Carcinoma, breast invasive carcinoma, hepatocellular carcinoma, clear-cell renal-cell carcinoma, Kidney Chromophobe cancer, renal papillary cell carcinoma, Head and Neck squamous cell carcinoma, colon adenocarcinoma, stomach adenocarcinoma, thyroid carcinoma, prostate adenocarcinoma. Elevated expression of PKMYT 1 is associated with poor prognosis in adrenocortical carcinoma, kidney chromophobe, kidney renal clear cell carcinoma, kidney renal papillary cell carcinoma, lower grade glioma, liver hepatocellular carcinoma, lung adenocarcinoma, mesothelioma, pancreatic adenocarcinoma, prostate adenocarcinoma, skin cutaneous melanoma, uveal melanoma (Shao et al., 2021), and breast cancer (Liu et al., 2020).
[0027] PKMYT1 is involved in the progression, invasion and / or metastasis of many solid tumours, for example non-small cell lung cancer (Zhang et al., 2022; He et al., 2021 ; Sun et al., 2019), osteosarcoma (Luo et al., 2022), clear cell renal cell carcinoma (Chen et al., 2020; Chen et al., 2021), oral squamous cell carcinoma (Cai et al., 2022), gastric cancer (Hu et al., 2022; Zhang et al., 2020), prostate cancer (Wang et al., 2020), oesophageal squamous cell carcinoma (Zhang et al., 2019), colorectal cancer (Jeong et al., 2018), hepatocellular carcinoma (Liu et al., 2017), ovarian cancer (Xuan et al., 2020), neuroblastoma (in particular with MYCN amplification) (Chayka et al., 2015), glioblastoma (Toledo et al., 2015). PKMYT1 is essential for survival of some haematologic malignancies, such as acute lymphoblastic leukemia and multiple myeloma (Ghelli Luserna di Rora et al., 2020).
[0028] PKMYT1 can have application in addressing resistance to treatment or improving the efficacy of cancer treatment agents. PKMYT 1 elevation has been reported as a resistance mechanism to sustained WEE1 inhibition (Lewis et al., 2019). PKMYT1 inhibitors may also be a useful second line treatment to complement the emerging WEE1i based therapies.
[0029] Knockdown of PKMYT1 can eliminate the radiation-induced G2 / M arrest, resulting in a lower survival rate for cells receiving radiation therapy and is therefore a promising target to improve the radiosensitivity of lung adenocarcinoma (Long et al., 2020). PKMYT1 could be also prove useful to enhance the efficacy of anti-microtubule cancer drugs (Visconti et al., 2017).
[0030] PKMYT1 also plays a role in viral infection. Knockdown of PKMYT1 reduces the number of cells supporting Kaposi sarcoma herpesvirus (KSHV) lytic infection in S phase of the cell cycle (Bryan et al., 2006). KSHV is the cause of Kaposi’s sarcoma, primary effusion lymphoma (PEL) and the plasmablastic variant of multicentric Castleman’s disease.
[0031] There is a clear need for PKMYT1 selective inhibitors with good pharmacokinetic properties, which are suitable for oral dosing with minimal or no toxicity.

[0131] The phrase “one or more groups” in the context of optional substituents (e.g., “one or more groups -R5”, etc.) is necessarily constrained by the parent moiety and the number of positions on it that are suitable for substitution. In some parent moieties (e.g., tetrazol- 1-yl) there is only one position available for substitution. However, for other parent moieties, there may be several (e.g., phenyl has five). Except when constrained by the parent moiety, the “one or more groups” may be, e.g., 1 , 2, 3, 4, etc., though more preferably is 1 , 2, or 3, yet more preferably 1 or 2, still more preferably 1 . Where optional substituents are chosen from "one or more" groups this definition includes all substituents being chosen from one of the specified groups or the substituents being chosen from two or more of the specified groups.
[0132] Unless otherwise indicated, where a compound is shown or described which has one or more chiral centres, and two or more stereoisomers are possible, all such stereoisomers are disclosed and encompassed, both individually (e.g., as isolated from the other stereoisomer(s)) and as mixtures (e.g., as equimolar or non-equimolar mixtures of two or more stereoisomers). For example, unless otherwise indicated, where a compound has one chiral centre, each of the (F?) and
[0133] (S) enantiomers are disclosed and encompassed, both individually (e.g., as isolated from the other enantiomer) and as a mixture (e.g., as equimolar or non-equimolar mixtures of the two enantiomers). For example, the initial carbon atom of a pendant sec-butyl group, -CH(CH3)CH2CH3 is usually chiral, and so gives rise to stereoisomers, e.g., (F?) and (S) enantiomers if it is the only chiral centre, each of which is disclosed and encompassed.

[0666] Substantially Purified Forms
[0667] One aspect of the present invention pertains to BAA compounds, as described herein, in substantially purified form and / or in a form substantially free from contaminants.
[0668] In one embodiment, the substantially purified form is at least 50% by weight, e.g., at least 60% by weight, e.g., at least 70% by weight, e.g., at least 80% by weight, e.g., at least 90% by weight, e.g., at least 95% by weight, e.g., at least 97% by weight, e.g., at least 98% by weight, e.g., at least 99% by weight.
[0669] Unless otherwise specified, the substantially purified form refers to the compound in any stereoisomeric or enantiomeric form. For example, in one embodiment, the substantially purified form refers to a mixture of stereoisomers, i.e., purified with respect to other compounds. In one embodiment, the substantially purified form refers to one stereoisomer, e.g., optically pure stereoisomer. In one embodiment, the substantially purified form refers to a mixture of enantiomers. In one embodiment, the substantially purified form refers to an equimolar mixture of enantiomers (i.e., a racemic mixture, a racemate). In one embodiment, the substantially purified form refers to one enantiomer, e.g., optically pure enantiomer.
[0670] In one embodiment, the contaminants represent no more than 50% by weight, e.g., no more than 40% by weight, e.g., no more than 30% by weight, e.g., no more than 20% by weight, e.g., no more than 10% by weight, e.g., no more than 5% by weight, e.g., no more than 3% by weight, e.g., no more than 2% by weight, e.g., no more than 1 % by weight.
[0671] Unless specified, the contaminants refer to other compounds, that is, other than stereoisomers or enantiomers. In one embodiment, the contaminants refer to other compounds and other stereoisomers. In one embodiment, the contaminants refer to other compounds and the other enantiomer.
[0672] In one embodiment, the substantially purified form is at least 60% optically pure (i.e. , 60% of the compound, on a molar basis, is the desired stereoisomer or enantiomer, and 40% is the undesired stereoisomer or enantiomer), e.g., at least 70% optically pure, e.g., at least 80% optically pure, e.g., at least 90% optically pure, e.g., at least 95% optically pure, e.g., at least 97% optically pure, e.g., at least 98% optically pure, e.g., at least 99% optically pure.
[0673] Isomers
[0674] Certain compounds may exist in one or more particular geometric, optical, enantiomeric, diastereoisomeric, epimeric, atropic, stereoisomeric, tautomeric, conformational, or anomeric forms, including but not limited to, cis- and trans-forms; E- and Z-forms; c-, t-, and r- forms; endo- and exo-forms; R-, S-, and meso-forms; D- and L-forms; d- and l-forms; (+) and (-) forms; keto-, enol-, and enolate-forms; syn- and anti-forms; synclinal- and anticlinal-forms; a- and p-forms; axial and equatorial forms; boat-, chair-, twist-, envelope-, and halfchair-forms; and combinations thereof, hereinafter collectively referred to as “isomers” (or “isomeric forms”).
[0675] A reference to a class of structures may well include structurally isomeric forms falling within that class (e.g., Ci-ealkyl includes n-propyl and iso-propyl; butyl includes n-, iso-, sec-, and tert-butyl; methoxyphenyl includes ortho-, meta-, and para-methoxyphenyl). However, reference to a specific group or substitution pattern is not intended to include other structural (or constitutional isomers) which differ with respect to the connections between atoms rather than by positions in space. For example, a reference to a methoxy group, -OCH3, is not to be construed as a reference to its structural isomer, a hydroxymethyl group, -CH2OH. Similarly, a reference specifically to ortho-chlorophenyl is not to be construed as a reference to its structural isomer, meta-chlorophenyl.
[0676] The above exclusion does not pertain to tautomeric forms, for example, keto-, enol-, and enolate-forms, as in, for example, the following tautomeric pairs: keto / enol (illustrated below), imine / enamine, amide / imino alcohol, amidine / amidine, nitroso / oxime, thioketone / enethiol, N-nitroso / hydroxyazo, and nitro / aci-nitro. A reference herein to one tautomer is intended to encompass both tautomers. keto enol enolate For example, 1 H-pyridin-2-one-5-yl and 2-hydroxyl-pyridin-5-yl (shown below) are tautomers of one another. A reference herein to one is intended to encompass both.
[0677] 1 H-pyridin-2-one-5-yl 2-hydroxyl-pyridin-5-yl
[0678] Note that specifically included in the term “isomer” are compounds with one or more isotopic substitutions. For example, H may be in any isotopic form, including1H,2H (D), and3H (T); C may be in any isotopic form, including12C,13C, and14C; O may be in any isotopic form, including16O and18O; and the like.
[0679] Unless otherwise specified, a reference to a particular compound includes all such isomeric forms, including mixtures (e.g., racemic mixtures) thereof. Methods for the preparation (e.g., asymmetric synthesis) and separation (e.g., fractional crystallisation and chromatographic means) of such isomeric forms are either known in the art or are readily obtained by adapting the methods taught herein, or known methods, in a known manner.
[0680] Unless otherwise specified, a reference to a particular compound includes all such isomeric forms, including mixtures (e.g., racemic mixtures) thereof. Methods for the preparation (e.g., asymmetric synthesis) and separation (e.g., fractional crystallisation and chromatographic means) of such isomeric forms are either known in the art or are readily obtained by adapting the methods taught herein, or known methods, in a known manner.
[0681] Salts
[0682] It may be convenient or desirable to prepare, purify, and / or handle a corresponding salt of the compound, for example, a pharmaceutically-acceptable salt. The term “salt” is used herein to refer to a solid complex comprising a first co-forming entity (e.g. a compound such as a BAA compound) and a second co-forming entity (e.g. a suitable Bronsted acid or base), where there is complete transfer of a proton from one entity to another. Examples of pharmaceutically acceptable salts are discussed in Berge et al., 1977, “Pharmaceutically Acceptable Salts,” J. Pharm. Sci., Vol. 66, pp. 1-19.
[0683] For example, if the compound is anionic, or has a functional group, which may be anionic (e.g., -COOH may be -COO'), then a salt may be formed with a suitable cation. Examples of suitable inorganic cations include, but are not limited to, alkali metal ions such as Na+and K+, alkaline earth cations such as Ca2+and Mg2+, and other cations such as Al3+as well as the ammonium ion (i.e., NF ). Examples of suitable organic cations include, but are not limited to substituted ammonium ions (e.g., NHsR+, NH2R2+, NHRs+, NR4+), for example, where each R is independently linear or branched saturated Ci-isalkyl , Cs-scycloalkyl, Cs-scycloalkyl-Ci-ealkyl, and phenyl-Ci-ealkyl, wherein the phenyl group is optionally substituted. Examples of some suitable substituted ammonium ions are those derived from: ethylamine, diethylamine, dicyclohexylamine, triethylamine, butylamine, ethylenediamine, ethanolamine, diethanolamine, piperazine, benzylamine, phenylbenzylamine, choline, meglumine, and tromethamine, as well as amino acids, such as lysine and arginine. An example of a common quaternary ammonium ion is N(CH3)4+.
[0684] If the compound is cationic, or has a functional group, which upon protonation may become cationic (e.g., -NH2 may become -NH3+), then a salt may be formed with a suitable anion.
[0685] For example, if a parent structure contains a cationic group (e.g., -NMe2+), or has a functional group, which upon protonation may become cationic (e.g., -NH2 may become -NH3+), then a salt may be formed with a suitable anion. In the case of a quaternary ammonium compound a counter-anion is generally always present in order to balance the positive charge. If, in addition to a cationic group (e.g., -NMe2+, -NH3+), the compound also contains a group capable of forming an anion (e.g., -COOH), then an inner salt (also referred to as a zwitterion) may be formed.
[0686] Examples of suitable inorganic anions include, but are not limited to, those derived from the following inorganic acids: hydrochloric, hydrobromic, hydroiodic, sulfuric, sulfurous, nitric, nitrous, phosphoric, and phosphorous.
[0687] Examples of suitable organic anions include, but are not limited to, those derived from the following organic acids: 2-acetyloxybenzoic, acetic, trifluoroacetic, ascorbic, aspartic, benzoic, camphorsulfonic, cinnamic, citric, edetic, 1,2-ethanedisulfonic, ethanesulfonic, fumaric, glucoheptonic, gluconic, glutamic, glycolic, hydroxymaleic, hydroxynaphthalene carboxylic, isethionic, lactic, lactobionic, lauric, maleic, malic, methanesulfonic, mucic, oleic, oxalic, palmitic, pamoic, pantothenic, phenylacetic, phenylsulfonic, propionic, pyruvic, salicylic, stearic, succinic, sulfanilic, tartaric, toluenesulfonic, and valeric. Examples of suitable polymeric organic anions include, but are not limited to, those derived from the following polymeric acids: tannic acid, carboxymethyl cellulose.
[0688] Examples of suitable counter-ions which are especially suitable for quaternary ammonium compounds (e.g., those with a -NMe2+group) include 1 -adamantanesulfonate, benzenesulfonate, bisulfate, bromide, chloride, iodide, methanesulfonate, methylsulfate, 1 ,5-napthalene-bis-sulfonate, 4-nitrobenzenesulfonate, formate, tartrate, tosylate, trifluoroacetate, trifluoromethylsulfonate, sulphate. Again, if the compound also contains a group capable of forming an anion (e.g., -COOH), then an inner salt may be formed.
[0689] Unless otherwise specified, a reference to a particular compound also includes salt forms thereof.

[0692] It may be convenient or desirable to prepare, purify, and / or handle a corresponding solvate of the compound. The term “solvate” is used herein in the conventional sense to refer to a complex of solute (e.g., compound, salt of compound) and solvent. If the solvent is water, the solvate may be conveniently referred to as a hydrate, for example, a mono-hydrate, a di-hydrate, a tri-hydrate, etc.
[0693] Unless otherwise specified, a reference to a particular compound also includes solvate and hydrate forms thereof.
[0694] In one embodiment, the BAA compound is provided in the form of a solvate.
[0695] In one embodiment, the BAA compound is provided in the form of a hydrate.
[0696] In one embodiment, the BAA compound is provided in unsolvated form.
[0697] Chemically Protected Forms
[0698] It may be convenient or desirable to prepare, purify, and / or handle the compound in a chemically protected form. The term “chemically protected form” is used herein in the conventional chemical sense and pertains to a compound in which one or more reactive functional groups are protected from undesirable chemical reactions under specified conditions (e.g., pH, temperature, radiation, solvent, reactive chemical reagents, and the like). In practice, well-known chemical methods are employed to reversibly render unreactive a functional group, which otherwise would be reactive, under specified conditions. In a chemically protected form, one or more reactive functional groups are in the form of a protected or protecting group (alternatively as a masked or masking group or a blocked or blocking group). By protecting a reactive functional group, reactions involving other unprotected reactive functional groups can be performed, without affecting the protected group; the protecting group may be removed or the masking group transformed, usually in a subsequent step, without substantially affecting the remainder of the molecule. See, for example, Protective Groups in Organic Synthesis (T. Green and P. Wuts; 4th Edition; John Wiley and Sons, 2006).
[0699] A wide variety of such “protecting,” “blocking,” or “masking” methods are widely used and well known in organic synthesis. For example, a compound which has two non-equivalent reactive functional groups, both of which would be reactive under specified conditions, may be derivatized to render one of the functional groups “protected,” and therefore unreactive, under the specified conditions; so protected, the compound may be used as a reactant which has effectively only one reactive functional group. After the desired reaction (involving the other functional group) is complete, the protected group may be “deprotected” to return it to its original functionality.
[0700] For example, a hydroxy group may be protected as an ether (-OR) or an ester (-OC(=O)R), for example, as: a t-butyl ether; a benzyl, benzhydryl (diphenylmethyl), or trityl (triphenylmethyl) ether; a trimethylsilyl or t-butyldimethylsilyl ether; or an acetyl ester (-OC(=O)CH3, -OAc). For example, an aldehyde or ketone group may be protected as an acetal (R-CH(OR)2) or ketal (R2C(OR)2), respectively, in which the carbonyl group (>C=O) is converted to a 1,1 -diether (>C(OR)2), by reaction with, for example, a primary alcohol in the presence of an acid. The aldehyde or ketone group is readily regenerated, for example, by hydrolysis using water in the presence of acid.
[0701] For example, an amine group may be protected, for example, as an amide (-NRCO-R), for example: as an acetamide (-NHCO-CH3); or as a carbamate (-NRCO-OR), for example: as a benzyloxy carbamate (-NHCO-OCH2C6Hs, -NH-Cbz), as a t-butoxy carbamate (-NHCO-OC(CH3)3, -NH-BOC); as a 2-biphenyl-2-propoxy carbamate (-NHCO-OC(CH3)2C6H4C6HS, -NH-Bpoc), as a 9-fluorenylmethoxy carbamate (-NH-Fmoc), as a 6- nitroveratryloxy carbamate (-NH-Nvoc), as a 2-trimethylsilylethyloxy carbamate (-NH-Teoc), a 2,2,2-trichloroethyloxy carbamate (-NH-Troc), as an allyloxy amide (-NH-Alloc), or as a 2(- phenylsulfonyl)ethyloxy carbamate (-NH-Psec); or, in suitable cases (e.g., cyclic amines), as a nitroxide radical (>N-O»); or, in suitable cases (e.g., heterocyclic nitrogens), as a 2- trimethylsilylethoxymethyl (N-SEM).
[0702] For example, a carboxylic acid group may be protected as an ester for example, as: an Ci-?alkyl ester (e.g., a methyl ester; a t-butyl ester); a C haloalkyl ester (e.g., a 2,2,2-trihaloethyl ester); a 2-tri(Ci-7alkyl)silyl-ethyl ester; or a Cs-2oaryl-Ci-7alkyl ester (e.g., a benzyl ester; a nitrobenzyl ester); or as an amide or hydrazide, for example, as acetamide or a N,N,N -trimethylhydrazide.
[0703] For example, a thiol group may be protected as a thioether (-SR), for example, as: a benzyl thioether; an acetamidomethyl ether (-S-CH2NHC(=O)CH3).
[0704] Prodrugs
[0705] It may be convenient or desirable to prepare, purify, and / or handle the compound in the form of a prodrug. The term “prodrug,” as used herein, pertains to a compound, which yields the desired active compound in vivo. Typically, the prodrug is inactive, or less active than the desired active compound, but may provide advantageous handling, administration, or metabolic properties.
[0706] For example, some prodrugs are esters of the active compound (e.g., a physiologically acceptable metabolically labile ester). During metabolism, the ester group (-C(=O)OR) is cleaved to yield the active drug. Such esters may be formed by esterification, for example, of any of the carboxylic acid groups (-C(=O)OH) in the parent compound, with, where appropriate, prior protection of any other reactive groups present in the parent compound, followed by deprotection if required.
[0707] Also, some prodrugs are activated enzymatically to yield the active compound, or a compound, which, upon further chemical reaction, yields the active compound (for example, as in antibody directed enzyme prodrug therapy (ADEPT), gene directed enzyme prodrug therapy (GDEPT), ligand-directed enzyme prodrug therapy (LIDEPT), etc.). For example, the prodrug may be a sugar derivative or other glycoside conjugate, or may be an amino acid ester derivative.

Optionally, a hydrophilic emulsifier is included together with a lipophilic emulsifier which acts as a stabiliser. It is also preferred to include both an oil and a fat. Together, the emulsifier(s) with or without stabiliser(s) make up the so-called emulsifying wax, and the wax together with the oil and / or fat make up the so-called emulsifying ointment base which forms the oily dispersed phase of the cream formulations.
[1003] Suitable emulgents and emulsion stabilisers include Tween 60, Span 80, cetostearyl alcohol, myristyl alcohol, glyceryl monostearate and sodium lauryl sulfate. The choice of suitable oils or fats for the formulation is based on achieving the desired cosmetic properties, since the solubility of the compound in most oils likely to be used in pharmaceutical emulsion formulations may be very low. Thus the cream may be a non-greasy, non-staining and washable product with suitable consistency to avoid leakage from tubes or other containers. Straight or branched chain, mono- or dibasic alkyl esters such as di-isoadipate, isocetyl stearate, propylene glycol diester of coconut fatty acids, isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate, 2- ethylhexyl palmitate or a blend of branched chain esters known as Crodamol CAP may be used, the last three being preferred esters. These may be used alone or in combination depending on the properties required. Alternatively, high melting point lipids such as white soft paraffin and / or liquid paraffin or other mineral oils can be used. Formulations suitable for intranasal administration, where the carrier is a liquid, include, for example, nasal spray, nasal drops, or by aerosol administration by nebuliser, include aqueous or oily solutions of the compound.
[1004] Formulations suitable for intranasal administration, where the carrier is a solid, include, for example, those presented as a coarse powder having a particle size, for example, in the range of about 20 to about 500 microns which is administered in the manner in which snuff is taken, i.e., by rapid inhalation through the nasal passage from a container of the powder held close up to the nose.
[1005] Formulations suitable for pulmonary administration (e.g., by inhalation or insufflation therapy) include those presented as an aerosol spray from a pressurised pack, with the use of a suitable propellant, such as dichlorodifluoromethane, trichlorofluoromethane, dichorotetrafluoroethane, carbon dioxide, or other suitable gases.
[1006] Formulations suitable for ocular administration include eye drops wherein the compound is dissolved or suspended in a suitable carrier, especially an aqueous solvent for the compound.
[1007] Formulations suitable for rectal administration may be presented as a suppository with a suitable base comprising, for example, natural or hardened oils, waxes, fats, semi-liquid or liquid polyols, for example, cocoa butter or a salicylate; or as a solution or suspension for treatment by enema.
[1008] Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or spray formulations containing in addition to the compound, such carriers as are known in the art to be appropriate.
[1009] Formulations suitable for parenteral administration (e.g., by injection), include aqueous or non-aqueous, isotonic, pyrogen-free, sterile liquids (e.g., solutions, suspensions), in which the compound is dissolved, suspended, or otherwise provided (e.g., in a liposome or other micro particulate). Such liquids may additionally contain other pharmaceutically acceptable ingredients, such as antioxidants, buffers, preservatives, stabilisers, bacteriostats, suspending agents, thickening agents, and solutes which render the formulation isotonic with the blood (or other relevant bodily fluid) of the intended recipient. Examples of excipients include, for example, water, alcohols, polyols, glycerol, vegetable oils, and the like. Examples of suitable isotonic carriers for use in such formulations include Sodium Chloride Injection, Ringer's Solution, or Lactated Ringer's Injection. Typically, the concentration of the compound in the liquid is from about 1 ng / mL to about 10 pg / mL, for example from about 10 ng / mL to about 1 pg / mL. The formulations may be presented in unit-dose or multi-dose sealed containers, for example, ampoules and vials, and may be stored in a freeze-dried (lyophilised) condition requiring only the addition of the sterile liquid carrier, for example water for injections, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules, and tablets. Dosage
[1010] It will be appreciated by one of skill in the art that appropriate dosages of the BAA compounds, and compositions comprising the BAA compounds, can vary from subject to subject (e.g., from patient to patient). Determining the optimal dosage will generally involve balancing the level of therapeutic benefit against any risk or deleterious side effects. The selected dosage level will depend on a variety of factors including, for example: the activity of the particular BAA compound; the route of administration; the time of administration; the rate of excretion of the BAA compound; the duration of the treatment; other drugs, compounds, and / or materials used in combination; the severity of the disorder; and the species, sex, age, weight, condition, general health, and prior medical history of the subject (e.g., patient). The amount of BAA compound and route of administration will ultimately be at the discretion of the physician, veterinarian, or clinician, although generally the dosage will be selected to achieve local concentrations at the site of action which achieve the desired effect without causing substantial harmful or deleterious side-effects.
[1011] Administration can be effected in one dose, continuously or intermittently (e.g., in divided doses at appropriate intervals) throughout the course of treatment. Methods of determining the most effective means and dosage of administration are well known to those of skill in the art and will vary with the formulation used for therapy, the purpose of the therapy, the target cell(s) being treated, and the subject being treated. Single or multiple administrations can be carried out with the dose level and pattern being selected by the treating physician, veterinarian, or clinician.
[1012] In general, a suitable dose of the BAA compound is in the range of about 0.01 mg to about 5000 mg (more typically about 0.1 mg to about 1000 mg, e.g., about 0.1 mg to about 300 mg) per day.
[1013] Where the compound is a pharmaceutically acceptable salt or solvate thereof, the amount administered is calculated on the basis of the parent compound and so the actual weight to be used is increased proportionately.
