Abstract

The present invention relates to a compound having a structure of formula I or a pharmaceutically acceptable salt of the compound. Regarding the compound, R1 is selected from hydrogen, fluorine, and chlorine; R2 and R3 are independently selected from hydrogen, alkyl, substituted alkyl, alkenyl or substituted alkenyl, alkynyl or substituted alkynyl, and aryl, wherein R2 and R3 can be bonded to forma ring, and the ring can be cycloalkyl, substituted cycloalkyl, an aromatic heterocyclic ring or a non-aromatic heterocyclic ring; R4 is selected from hydrogen, cyano, alkyl, substituted alkyl, alkene or substituted alkenyl, alkynyl or substituted alkynyl, and aryl; R5 is selected from hydrogen, halogen, and haloalkyl. The invention further relates to a pharmaceutical composition comprising the compound. The compound and composition provided by the invention shows significant activity in the treatment of prostate cancer. (The formulas are shown in the description.).

Description

technical field [0001] The present invention relates to novel antagonist compounds of the androgen receptor; to methods of using such compounds in the treatment of diseases associated with the androgen receptor, such as prostate cancer; and to pharmaceutical combinations comprising these compounds. Background technique [0002] Androgen receptor (AR) is a ligand-dependent transcriptional regulatory protein that belongs to the nuclear receptor superfamily. Binding of the androgen receptor and an androgen, such as testosterone or, more effectively, dihydrotestosterone (DTH), results in a conformational change leading to activation of the androgen receptor. The activated androgen receptor binds to a specific DNA sequence in the nucleus of the target cell in the form of a dimer - the Androgen Response Element (ARE), regulates the expression of the target gene, and produces corresponding biological effects on cell proliferation, survival and differentiation. The androgen recepto...
