Definitions
- the present invention relates to an imidazole ketone-based androgen receptor antagonist, a process for the preparation thereof and use thereof.
- Prostate cancer is one of the most common malignant tumors in men and has become a major problem in the health of men and men, and its mortality rate has been high worldwide, although the incidence of prostate cancer in China is lower than in the West. However, in recent years, it has been at a rapid development level, increasing nearly 10 times in the past 20 years, and has risen to become the sixth place in China's male malignant tumors. These proportions will continue to rise as the population of China's aging population increases. Prostate cancer is driven by androgens, and its tumor growth must be sufficient to maintain intratumoral androgen, which in turn continues to activate the androgen receptor. Androgen deprivation therapy (ADT) has been the standard treatment for advanced prostate cancer since 1941.
- ADT Androgen deprivation therapy
- prostate cancer patients who receive androgen deprivation therapy eventually progress to metastatic castration-resistant prostate cancer (m-CRPC).
- m-CRPC metastatic castration-resistant prostate cancer
- AR activated androgen receptor
- the treatment of CRPC by inhibiting androgen synthesis is mainly divided into two categories, one is anti-androgen drugs, including progesterone-releasing hormone (LHRH), such as leuprolide, CYP17 inhibitor abiraterone;
- the second is AR antagonists, such as enzalutamide and bicalutamide, among which enzalutamide, also known as MDV3100, trade name Xtandi, was developed by Medivation and approved by the FDA in August 2012 for m - CRPC treatment, prostate specific antigen (PSA) levels are reduced by up to 89% after taking the drug for one month, and enzalutamide may be effective in the treatment of certain types of breast cancer, sold in 2015 after three years of marketing The amount reached 2.28 billion US dollars, ranking first in the prostate cancer drug sales market, and other similar research drugs such as ARN-509 (Apalutamide), ONC1-13B, ODM-201 (Darolutamide) and domestic Proxalutamide.

Abstract
本发明公开了一种咪唑酮类雄激素受体拮抗剂、其制备方法和用途。本发明的咪唑酮类雄激素受体拮抗剂的结构如式I所示,可用于治疗和预防与雄激素受体相关的疾病,如前列腺癌等。
Description
本申请要求申请日为2017年8月22日的中国专利申请CN201710726874.9的优先权。本申请引用上述中国专利申请的全文。
本发明涉及一种咪唑酮类雄激素受体拮抗剂、其制备方法和用途。
前列腺癌是男性最常见的恶性肿瘤之一,目前已经成为人类男性健康的主要问题,而且其在世界范围内的死亡率一直居高不下,尽管和西方相比,我国的前列腺癌发病率较低,但是近年来一直处于快速发展水平,二十年来增加了近10倍,而且已经上升成为我国男性恶性肿瘤的第6位,这些比例都会随着中国老年化人口的增加而不断攀升。前列腺癌是由雄激素驱动,而且其肿瘤生长必需足够的肿瘤内雄激素来维持,进而持续对雄激素受体进行激活。自从1941年以来,雄激素去势治疗(ADT)一直是晚期前列腺癌的标准治疗。但是不幸的是,接受雄激素去势治疗的大多数前列腺癌患者最终都会进展到转移性去势抵抗性前列腺癌(m-CRPC)。而且发展成CRPC状态后的2-4年内,前列腺癌患者的死亡率最高,在这期间激活的雄激素受体(AR)仍然起着非常关键的作用,机制上包括AR基因的过度表达或参与其它酶的上调机制。
目前利用抑制雄激素合成的治疗CRPC的方案主要分为两类,一是抗雄激素类药物,包括促黄体酮激素释放激素(LHRH),如亮丙瑞林、CYP17抑制剂阿比特龙等;二是AR拮抗剂,如恩杂鲁胺和比卡鲁胺等,其中恩杂鲁胺(enzalutamide),又名MDV3100,商品名Xtandi,由Medivation开发,2012年8月份被FDA批准上市用于m-CRPC的治疗,在服用药物一个月后,前列腺特异性抗原(PSA)水平降低高达89%,而且恩杂鲁胺对某些类型乳腺癌的治疗也可能有效,上市三年后于2015年销售额就达到了22.8亿美元,跃居前列腺癌药物销售市场首位,其它类似的在研药物还有如ARN-509(Apalutamide)、ONC1-13B、ODM-201(Darolutamide)和国内的Proxalutamide等。
目前公开的其它AR拮抗剂的专利包括WO2012119559A1、WO2012011840、WO2012015723、CN201280052853等。
鉴于市场上对于AR拮抗剂药物的大量需要,以及某些AR拮抗剂出现了耐受性,我们更加需要开发出疗效更佳和安全性更好的药物。
