Pyridine androstane derivative and application thereof to preparing medicine for preventing and/or treating prostatic cancer

Abstract

The invention relates to a novel pyridine androstane derivative and application thereof to preparing a medicine for preventing and / or treating prostatic cancer. The pyridine androstane derivative disclosed by the invention is an ideal selective cytochrome oxidase CYP450c17 inhibitor and can be used for treating or preventing various indications relative to male hormonal functions, in particular prostatic cancer. The pyridine androstane derivative has lower oxidative metabolism and higher effective bioavailability, therefore having the advantages of less application dosage, better tolerance and little side effect.

Description

technical field [0001] The present invention relates to pyridine androster derivatives and their use in the preparation of drugs for preventing and / or treating prostate cancer. Background technique [0002] Important male hormones are testosterone, androsterone, androdione, and dehydroepiandrosterone. Testosterone is secreted by the Leydig cells of the testes and is the most important male hormone in the body. Androsterone, androdione, and dehydroepiandrosterone are metabolites of testosterone (testosterone → androsterone → androdione → dehydroepiandrosterone). The adrenal cortex also secretes a male hormone, adrenal androsterone. These hormones can stimulate the growth of prostate cancer. Therefore, the first choice for the treatment of prostate cancer is to suppress the production of androgen in the testes through drugs or surgery. However, these methods do not block androgen production in other parts of the body. [0003] Steroid hormone synthesis starts from cholest...
