Description

Aminopyrimidines as ALK inhibitors

Technical Field

The present disclosure provides inhibitors of anaplastic lymphoma kinase and therapeutic methods for treating conditions and diseases in which inhibition of anaplastic lymphoma kinase provides a benefit.

Background

Anaplastic Lymphoma Kinase (ALK) is a member of the insulin receptor superfamily of receptor tyrosine kinases, which have been implicated in the development of hematopoietic and non-hematopoietic tumors. Abnormal expression of the full-length ALK receptor protein has been reported in neuroblastoma and glioblastoma; and ALK fusion proteins are present in anaplastic large cell lymphomas. The study of ALK fusion proteins also opens the possibility for new therapeutic treatments for ALK-positive malignant patients. Pulford et al, cell and molecular Life sciences (cell. mol. Life. Sci.) 61:2939-2953 (2004).

Small molecule ALK inhibitors have therapeutic potential for the treatment of diseases and conditions in which ALK plays a role, including cancer. Roskoski, Pharmacological Research 68: 68-94 (2013). ALK inhibitors are disclosed in u.s.8,039,479 and WO 2015/130014.

There is a continuing need for new agents, such as small molecules, for the treatment and/or prevention of cancer and other diseases that respond to ALK inhibition.

Certain compounds of the present disclosure may exist as stereoisomers, i.e., isomers that differ only in the spatial arrangement of the atoms, including optical isomers and conformational isomers (or conformers) and tautomers. The present disclosure includes all stereoisomers as pure individual stereoisomeric formulations and respective enriched formulations, and racemic mixtures of such stereoisomers as well as individual diastereomers and enantiomers which can be separated according to methods well known to those skilled in the art.

As used herein, the term "stereoisomer" is a generic term for all isomers of a single molecule that differ only in the orientation of their atoms in space. It includes enantiomers and isomers of compounds having more than one chiral center, which isomers are not mirror images of each other (diastereomers).

The term "chiral center" or "asymmetric carbon atom" refers to a carbon atom that is attached to four different groups.

The terms "enantiomer" and "enantiomeric" refer to a molecule that is not superposed on its mirror image and is therefore optically active, wherein the enantiomer rotates plane-polarized light in one direction and its mirror image compound rotates plane-polarized light in the opposite direction.

The term "racemic" or "racemate" refers to a mixture of equal parts of enantiomers, and which mixture is optically inactive.

The term "absolute configuration" refers to the spatial arrangement of atoms of a chiral molecular entity (or group) and its stereochemical description, e.g., R or S.

The stereochemical terms and conventions used in this specification are intended to be consistent with those described in Pure and applied chemistry (Pure & appl. chem) 68:2193(1996), unless otherwise indicated.

The term "enantiomeric excess" or "ee" refers to a measure of how much of one enantiomer is present compared to the other. For a mixture of R and S enantiomers, the percent enantiomeric excess is defined as | R-S | _ 100, where R and S are the respective molar or weight fractions of the enantiomers in the mixture such that R + S ═ 1. By knowing the optical rotation of the chiral material, the percent enantiomeric excess is defined as ([ alpha ]]_obs/[α]_max) 100 of [ α ], wherein]_obsIs the optical rotation of a mixture of enantiomers, [ alpha ]]_maxIs the optical rotation of a pure enantiomer. Enantiomeric excess can be determined using a variety of analytical techniques, including NMR spectroscopy, chiral column chromatography, or optical polarization determination. Certain compounds of the present disclosure can have an ee of about 70% or more, e.g., about 80% or more, about 90% or more, about 91% or more, about 92% or more, about 93% or more, about 94% or more, about 95% or more, about 96% or more, about 97% or more, about 98% or more, or about 99% or more.

The term "enantiomerically pure" or "enantiomerically pure" refers to a sample of a chiral substance having all of its molecules (within the limits of detection) with the same chiral handedness.

The term "enantiomerically enriched" or "enantiomerically enriched" refers to a sample of a chiral substance having an enantiomeric ratio of greater than 50: 50. The enantiomerically enriched compound may be enantiomerically pure.

Salts, hydrates, and solvates of the disclosed compounds may also be used in the methods disclosed herein. The present disclosure includes the preparation and use of salts of the compounds of the present disclosure. As used herein, a pharmaceutically "pharmaceutically acceptable salt" refers to a salt or zwitterionic form of a compound of the disclosure. Salts of the compounds of the present disclosure may be prepared during the final isolation and purification of the compounds or separately by reacting the compounds with an acid having a suitable cation. Pharmaceutically acceptable salts of the compounds of the present disclosure may be acid addition salts formed with pharmaceutically acceptable acids. Examples of acids that can be used to form pharmaceutically acceptable salts include inorganic acids such as nitric acid, boric acid, hydrochloric acid, hydrobromic acid, sulfuric acid, and phosphoric acid, and organic acids such as oxalic acid, maleic acid, succinic acid, and citric acid.

The present disclosure includes the preparation and use of solvates of the compounds of the present disclosure. Solvates do not generally significantly alter the physiological activity or toxicity of the compound and may therefore act as pharmacological equivalents. As used herein, the term "solvate" is a combination, physical association, and/or solvation of a compound of the present disclosure with a solvent molecule, e.g., a di-solvate, mono-solvate, or semi-solvate, wherein the ratio of solvent molecules to compound of the present disclosure is about 2:1, about 1:1, or about 1:2, respectively. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding. In some cases, the solvate may be isolated, for example, when one or more solvent molecules are incorporated into the crystal lattice of the crystalline solid. Thus, "solvate" includes both solution phase and isolatable solvates. The disclosed compounds may exist in solvated forms with pharmaceutically acceptable solvents (e.g., water, methanol, and ethanol), and the present disclosure is intended to include both solvated and unsolvated forms of the disclosed compounds.

One solvate type is the hydrate. "hydrates" refers to a particular subgroup of solvates, wherein the solvent molecule is water. Solvates may generally function as pharmacological equivalents. The preparation of solvates is known in the art. See, e.g., m.caira et al, journal of pharmaceutical sciences (j.pharmacy.sci.) -93 (3):601-611(2004), which describes the preparation of solvates of fluconazole with ethyl acetate and with water. van Tonder et al, American society of pharmaceutical scientists medical science and technology (AAPS Pharm Sci. Tech.) (5) (1) Article 12(2004) and A.L. Bingham et al, Chem. Commun 603-. A typical, non-limiting method of preparing the solvate includes dissolving the disclosed compound in the desired solvent (organic, water or mixtures thereof) at a temperature of from greater than 20 ℃ to about 25 ℃, then cooling the solution at a rate sufficient to form crystals, and isolating the crystals by known methods, such as filtration. Analytical techniques such as infrared spectroscopy can be used to confirm the presence of solvent in the solvate crystals.
