Description

1,3,4,7-Tetrahydro-2H-pyrrolo[3',2':5,6]pyrido[2,3-b][1,4]oxazepine Bcl-2 Inhibitors CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No.63 / 267,018, filed January 21, 2022, the disclosure of which is incorporated by reference herein in its entirety. REFERENCE TO AN ELECTRONIC SEQUENCE LISTING

[0002] The contents of the electronic sequence listing (ABV12563USO1_ST26.xml; Size: 4,991 bytes; and Date of Creation: January 18, 2023) is herein incorporated by reference in its entirety. FIELD OF THE INVENTION

[0003] This invention pertains to compounds which inhibit the activity of a Bcl-2 protein, and compositions containing the compounds. BACKGROUND

[0004] The Bcl-2 protein is a key anti-apoptotic regulator of the intrinsic apoptosis pathway. Cellular expression of anti-apoptotic Bcl-2 protein is associated with inhibition of apoptosis and, in cases of overexpression, can result in certain cancers.

[0005] Molecules capable of inhibiting Bcl-2 protein activity may increase apoptosis, thereby leading to improved outcomes related to the treatment and prevention of chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). For example, venetoclax is a selective Bcl-2 inhibitor that was first approved by the FDA for the treatment of patients with CLL or SLL, with or without 17p deletion, who have received at least one prior therapy.

[0006] There is, however, a need in the therapeutic arts for compounds with improved activity which inhibit the activity of Bcl-2 protein. SUMMARY

DETAILED DESCRIPTION

[0023] The present invention describes compounds which inhibit the activity of Bcl-2 protein.

[0024] Compounds disclosed herein may contain one or more variable(s) that occur more than one time in any substituent or in the Formulae herein. Definition of a variable on each occurrence is independent of its definition at another occurrence. Further, combinations of substituents are permissible only if such combinations result in stable compounds. Stable compounds are compounds which can be isolated from a reaction mixture. Definitions

[0026] Certain terms as used in the specification are intended to refer to the following definitions, as detailed below.

[0027] It is noted that, as used in this specification and the intended claims, the singular form "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a compound" includes a single compound as well as one or more of the same or different compounds. Reference to "a pharmaceutically acceptable carrier" means a single pharmaceutically acceptable carrier as well as one or more pharmaceutically acceptable carriers, and the like.

[0028] As used in the specification and the appended claims, unless specified to the contrary, the following terms have the meaning indicated:

[0029] The term “C1-C6alkoxy,” as used herein, refers to an alkyl group having one, two, three, four, five, or six carbons, as defined herein, appended to the parent molecular moiety through an oxygen atom. Representative examples of “C1-C6alkoxy,” include, but are not limited to, methoxy, ethoxy, propoxy, 2-propoxy, butoxy, tert-butoxy, pentyloxy, and hexyloxy, and the like.

[0030] The term “C1-C6alkyl,” as used herein, refers to a saturated, straight or branched hydrocarbon chain radical having one, two, three, four, five, or six carbons unless otherwisespecified. Representative examples of alkyl include, but are not limited to, methyl, ethyl, n- propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert-butyl, n-pentyl, isopentyl, neopentyl, n-hexyl, 1-methylbutyl, 2-methylbutyl, 3-methylbutyl, 3,3-dimethylbutyl, 1,1-dimethylpropyl, 1,2- dimethylpropyl, 2,2-dimethylpropyl, 1-methylpropyl, 2-methylpropyl, 1-ethylpropyl, and 1,2,2- trimethylpropyl, and the like.

[0031] The term “ C2-C6alkoxyalkoxy,” as used herein, refers to an alkoxy group, as defined herein, appended to the parent molecular moiety through another alkoxy group, as defined herein. Representative examples of C2-C6alkoxyalkoxy include, but are not limited to, tert- butoxymethoxy, 2-ethoxyethoxy, 2-methoxyethoxy, methoxymethoxy, and the like.

[0032] The term “C2-C6alkoxyalkyl,” as used herein, refers to an alkoxy group, as defined herein, appended to the parent molecular moiety through an alkyl group, as defined herein. Representative examples of C2-C6alkoxyalkyl include, but are not limited to, tert-butoxymethyl, 2-ethoxyethyl, 2-methoxyethyl, and methoxymethyl, and the like.

[0033] The term "halo" or "halogen," as used herein, means Cl, Br, I, and F.

[0034] The term “C1-C6haloalkyl,” as used herein, refers to an alkyl group, as defined herein, in which one or more hydrogen atoms are replaced by halogen. Representative examples of C1-C6haloalkyl include, but are not limited to, chloromethyl, 2-fluoroethyl, 2,2-difluoroethyl, fluoromethyl, 2,2,2-trifluoroethyl, trifluoromethyl, difluoromethyl, fluoromethyl, pentafluoroethyl, 2-chloro-3-fluoropentyl, trifluorobutyl, and trifluoropropyl, and the like.

[0035] In some instances, the number of carbon atoms in a moiety is indicated by the prefix "Cx- Cy", wherein x is the minimum and y is the maximum number of carbon atoms in the substituent. Thus, for example, "C1-C6alkyl" means an alkyl substituent containing from 1 to 6 carbon atoms and "C1-C3alkyl" means an alkyl substituent containing from 1 to 3 carbon atoms.

[0036] If a moiety is described as being "optionally substituted," the moiety may be either (1) not substituted or (2) substituted. If a moiety is described as being optionally substituted with up to a particular number of non-hydrogen radicals, that moiety may be either (1) not substituted; or (2) substituted by up to that particular number of non-hydrogen radicals or by up to the maximum number of substitutable positions on the moiety, whichever is less.

[0037] With reference to the use of the words "comprise" or "comprises" or "comprising" in this patent application (including the claims), Applicants note that unless the context requires otherwise, those words are used on the basis and clear understanding that they are to beinterpreted inclusively, rather than exclusively, and that Applicants intend each of those words to be so interpreted in construing this patent application, including the claims below.

[0038] The phrase "pharmaceutical composition" refers to a composition suitable for administration in medical use.

[0039] The phrase "pharmaceutically acceptable salt" refers to those salts which are, within the scope of sound medical judgement, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like and are commensurate with a reasonable benefit / risk ratio.

[0040] The term "stable" refers to compounds that possess stability sufficient to allow manufacture and that maintain the integrity of the compound for a sufficient period of time to be useful for the purpose detailed herein.

[0041] If a moiety is described as "substituted," a non-hydrogen radical is in the place of hydrogen radical of any substitutable atom of the moiety. Thus, for example, a substituted heterocycle moiety is a heterocycle moiety in which at least one non-hydrogen radical is in the place of a hydrogen radical on the heterocycle. It should be recognized that if there are more than one substitution on a moiety, each non-hydrogen radical may be identical or different (unless otherwise stated).

[0042] The phrase "therapeutically effective amount" refers to an amount of a compound, or a pharmaceutically acceptable salt thereof, sufficient to prevent the development of or to alleviate to some extent one or more of the symptoms of the condition or disorder being treated when administered for treatment in a particular subject or subject population.

[0043] The terms "treat," "treating," and "treatment," as used herein, refer to a method of alleviating or abrogating a disease and / or its attendant symptoms.

[0044] The term “one or more” refers to one to five. In one embodiment, it refers to one or four. In another embodiment, it refers to one to four. In one embodiment, it refers to one or three. In another embodiment, it refers to one to three. In a further embodiment, it refers to one to two. In yet other embodiment, it refers to two. In yet other further embodiment, it refers to one.
