REGIMENS OF ESTROGEN RECEPTOR ANTAGONISTS
-
Paragraph 0087; 0098-0099, (2021/01/29)
Provided herein are methods of administering estrogen receptor antagonists for use in treatment of cancer. The antagonists (such as a hexahydro pyrido[3,4-b]indole, AZD9496, RAD-1901, ARN-810, endoxifen, or fulvestrant) may be an inhibitor of both activating function 1 and activating function 2 of the estrogen receptor. Also provided are combinations of above inhibitors with a secondary agent, which is a CDK 4/6 inhibitor (such as, palbocociclib, ribociclib, abemaciclib, lerociclib, and trilaciclib).

Herein, we report the identification and synthesis of a series of tricyclic indazoles as a novel class of selective estrogen receptor degrader antagonists. Replacement of a phenol, present in our previously reported tetrahydroisoquinoline scaffold, with an indazole group led to the removal of a reactive metabolite signal in an in vitro glutathione trapping assay. Further optimization, guided by X-ray crystal structures and NMR conformational work, varied the alkyl side chain and pendant aryl group and resulted in compounds with low turnover in human hepatocytes and enhanced chemical stability. Compound 9 was profiled as a representative of the series in terms of pharmacology and demonstrated the desired estrogen receptor α degrader-antagonist profile and demonstrated activity in a xenograft model of breast cancer.
