Abstract
本发明公开了一类甾体合成酶抑制剂及其治疗应用,属于医药领域。本发明提供的一类可作为药物的化合物具有抑制甾体合成酶的作用,且抑制率高,可以用作治疗激素依赖型疾病的药物。
Description
技术领域
本发明涉及医药技术领域,具体而言,涉及一类甾体合成酶抑制剂及其治疗应用。
背景技术
甾体激素是人体内重要的内源性调控因子,广泛的参与到各项生理和病理作用中。一旦其生物合成及信号感知和传导过程发生变化,就会引起各种严重疾病。而甾体合成酶是这些甾体激素生物合成的关键因素,对其进行抑制就可以直接降低甾体激素的浓度,进而治疗相关疾病。
以醛固酮为代表的盐皮质激素可以调节肾小管的功能,控制钾离子、钠离子及水的动态平衡,进而调节血容量和血压。近期研究表明醛固酮是强力的致炎因子,能够诱导活性氧,并可以上调包括PAI在内的多种致纤维化因子的表达。过高浓度的醛固酮与充血性心衰、难治性高血压、慢性肾病、糖尿病性肾病、高醛固酮症、心肾纤维化、心肾综合症、代谢综合症等疾病有直接关系。而醛固酮合成酶(CYP11B2)是醛固酮生物合成中的关键酶,对其进行抑制可以有效降低醛固酮水平,进而治疗相关疾病。
可的松是人体内重要的糖皮质激素,可以广泛调节免疫应答、压力反应、糖和脂质代谢。由于发生在下丘脑-垂体-肾上腺的肿瘤而引起的可的松异常过度分泌,被称为库欣综合症。而高水平的可的松也与代谢综合症、胰岛素抵抗、肥胖、二型糖尿病有直接关系。11β羟化酶(CYP11B1)是可的松生物合成中的关键酶,对其进行抑制可以有效降低可的松水平,进而治疗相关疾病。
雌激素和雄激素除维持正常性别特征和功能外,还调控成骨与破骨平衡,心血管功能,肌肉稳态等生理功能。但是过高浓度的雌激素和雄激素分别与乳腺癌和前列腺癌的发生、发展有密切关系。CYP19和CYP17分别是雌激素和雄激素生物合成中的关键酶,对其进行抑制可以有效降低雌激素和雄激素水平,进而治疗相关疾病。
胆汁酸是由肝脏分泌的内源性甾体,除在小肠内形成乳糜微粒帮助脂肪吸收外,还是潜力的信号因子,能广泛的调控糖和脂的合成与代谢、以及炎症和纤维化等病理过程。而CYP7A1与CYP8B1是胆汁酸生物合成中的关键酶,对其进行干预能够调节肝脏功能及机体代谢,是治疗非酒精性脂肪性肝病、脂肪肝、肝硬化及肝纤维化等疾病的潜在靶点。
鉴于此,特提出本发明。
