- the present invention relates to the field of drug synthesis, and in particular to a class of CYP11A1 (cytochrome P450 monooxygenase 11A1) inhibitor compounds, as well as preparation methods and uses of the compounds, and pharmaceutical compositions containing the compounds.
- CYP11A1 cytochrome P450 monooxygenase 11A1
- the compounds can be used to treat steroid hormone-dependent diseases.
- Prostate cancer is one of the common malignant tumors of the urogenital system in elderly men. Its incidence and mortality rate rank second and fifth in the global male malignant tumor incidence and mortality spectrum, respectively. It ranks first and third among men in European and American countries, and sixth and seventh among Chinese men. In recent years, with the aging of China's population and other factors, the incidence and mortality of prostate cancer have shown a clear upward trend, and the disease burden has become increasingly heavier. According to GLOBOCAN2020 data, there were approximately 115,000 new cases of prostate cancer in my country in 2020, accounting for 4.7% of all male malignant tumors, while new cases of prostate cancer in the United States in 2019 accounted for 20% of new male cancer patients that year.
- Castration therapy reduces the level of testosterone in plasma, but the disease still progresses.
- the characteristic is the high expression of androgen receptor AR. Trace amounts of androgens in the body can still activate the androgen receptor AR signal, resulting in continuous activation of the AR pathway.

Abstract

Description
本申请要求于2023年01月17日向中国知识产权局提交的申请号为202310060807.3,发明名称为“一类CYP11A1抑制剂化合物及其制备方法用途”的中国专利的优先权权益,于2023年01月06日向中国知识产权局提交的申请号为202310019758.9,发明名称为“一类CYP11A1抑制剂化合物及其制备方法用途”的中国专利的优先权权益以及于2023年06月07日向中国知识产权局提交的申请号为202310670257.7,发明名称为“一类CYP11A1抑制剂化合物及其制备方法用途”的中国专利的优先权权益,通过援引加入的方式将其全部内容整体并入本文。
本发明涉及药物合成领域,具体而言,涉及一类CYP11A1(细胞色素P450单加氧酶11A1)抑制剂化合物,以及所述化合物制备方法和用途,以及包含这些化合物的药物组合物,所述化合物可以用于治疗类固醇激素依赖的疾病。
前列腺癌是老年男性泌尿生殖系统常见的恶性肿瘤之一,其发病率和死亡率分别位列全球男性恶性肿瘤发病和死亡谱的第2位和第5位,在欧美国家男性中分别居首位和第3位,在中国男性中分别居第6位和第7位。近年来,随着中国人口老龄化加剧等原因,前列腺癌的发病和死亡呈明显上升趋势,疾病负担日益加重。GLOBOCAN2020数据显示,2020年我国前列腺癌新发病例约11.5万,占男性全部恶性肿瘤的4.7%,而2019年美国前列腺癌新发病例占当年新发癌症男性患者的20%。
对于阶段I-III的前列腺癌病人,现有标准治疗包括手术治疗或放射治疗等。早期阶段的前列腺癌(stage I/II)的治疗效果比较好,5年的无疾病进展期达到90%。但是,晚期前列腺癌的治愈率则很低。当前晚期前列腺癌的5年生存率只有30%。
类固醇激素与其同源受体的结合调节大多数前列腺癌和乳腺癌的生长。对于阶段IV或高风险的前列腺癌病人,用手术进行雄激素消除,或者化学阉割治疗能够有效控制疾病进展。第一代的抗雄激素疗法,如氟他胺、比卡鲁胺等就是用于这个阶段前列腺癌的治疗。
大部分的前列腺患者最终都会发展为去势疗法抵抗的前列腺癌(castration-resistant prostate cancer,CRPC),去势疗法降低血浆中睾丸素水平,但疾病仍然进展。特征是雄激素受体AR高表达,体内微量的雄激素仍可以激活雄激素受体AR信号,从而导致AR通路持续活化。
当前CRPC的治疗手段有限,阿比特龙和恩杂鲁胺是针对CRPC中雄激素受体持续激活发展出来的新疗法,通过进一步抑制雄激素合成,或阻断体内微量的雄激素与受体结合,治疗晚期CRPC。
但是,有相当一部分的前列腺患者对阿比特龙或恩杂鲁胺不敏感。此外,大部分的初始应答患者,在使用阿比特龙或恩杂鲁胺1-2年后,也会产生新的耐药。而大部分的阿比特龙或恩杂鲁胺耐药肿瘤,仍然是AR高表达,且持续活化状态。
肾上腺和前列腺癌本身可以合成和转化孕烯醇酮、孕酮、脱氢表雄酮及它们的衍生物为更活跃的雄激素,结合和激活AR。阿比特龙治疗后的患者体内孕烯醇酮升高,被认为是驱动耐药的主要机制,尤其是在雄激素受体点突变的肿瘤中。体内所有的类固醇激素都是从单一的前体-胆固醇转化为孕烯醇酮开始。这步反应由细胞色素P450scc(又叫胆固醇侧链裂解酶,或细胞色素P450单加氧酶11A1,CYP11A1)催化,是催化类固醇生成的第一步连续单加氧反应和限速步骤,完成20R,22R-二羟基胆固醇(20R,22R-DiOHCH)的C-C裂解,将胆固醇转换为孕烯醇酮。研究证实,抑制CYP11A1可迅速使血液中类固醇激素低于检测水平。而对机体同时补充糖皮质激素
和盐皮质激素即可有效避免机体正常生理机能受到类固醇激素缺乏的影响。
CYP11A1属于类固醇CYP基因家族,CYP11A1在几种类型的癌症中都存在过表达,并与耐药性有关。抑制CYP11A1酶将能抑制所有类固醇激素的合成,包括促进乳腺癌进展的雌激素和孕激素,及促进前列腺癌进展的雄激素等,从而充分抑制类固醇激素依赖肿瘤的进展,是很有前途的治疗靶标。

将胆固醇转化成孕烯醇酮是脊椎动物体内合成所有类固醇荷尔蒙的第一步限速步骤。这个转化反应包括由唯一的细胞色素P450scc(CYP11A)催化的两步连续单加氧化反应依次生成C22-羟基胆固醇和C20,C22-二羟基胆固醇,接着由CYP11A1催化的C20,C22-二羟基胆固醇中C20-C22碳-碳单键断裂生成一分子孕烯醇酮和一分子4-甲基戊醛。所以,通过检测化合物抑制孕烯醇酮合成能力来鉴定化合物抑制CYP11A1的抑制效果。
