Abstract
本发明涉及包括立体异构体、前药和其可药用盐或溶剂化物的式(I)三环吡啶类化合物、其制备方法、含有所述式(I)化合物的药物组合物及其在治疗促肾上腺皮质激素释放因子(CRF)介导的疾病中的用途。
Description
本发明涉及三环衍生物、其制备方法、含有所述三环衍生物的药物组合物及其在治疗中的用途。
第一促肾上腺皮质激素释放因子(CRF)已从羊下丘脑中分离出来,并确认为41-氨基酸肽(Vale等人,Science 213:1394-1397,1981)。现已发现,CRF会在内分泌、神经和免疫系统机能中产生深刻变化。CRF被认为是源自垂体前叶的促肾上腺皮质激素(″ACTH″)、B内啡呔和其它阿黑皮素原(″POMC″)衍生的肽基础释放和应激释放的主要生理调节剂(Vale等人,Science 213:1394-1397,1981)。
除了刺激产生ACTH和POMC的作用之外,CRF可能是关键中枢神经系统神经递质之一,且在整合身体对应激的总应答中起决定性作用。
用CRF直接对脑给药引起行为、生理和内分泌应答,该应答与处于应激环境之下的动物的应答相同。
相应地,临床数据表明CRF受体拮抗剂可用于治疗表现形式为CRF分泌过多的神经精神病,并且,尤其可以代表新的抗抑郁剂和/或抗焦虑药物。
第一CRF受体拮抗剂是肽(参见,例如,Rivier等,US 4605642;Rivier等,Science 224:889,1984)。尽管这些肽确定了CRF受体拮抗剂能减少对CRF的药理学应答,但是,肽CRF受体拮抗剂具有肽疗法的常规缺点,包括缺乏稳定性且口服活性有限。最近,报道了小分子CRF受体拮抗剂。
WO 00/27846公开下列通式(A)所示的CRF拮抗剂,
其条件是,A、B和C中至少一个为氮,A、B和C不全为氮,并且A-B或B-C是双键,A、B、C和X可以是氮或碳。
鉴于CRF的生理重要性,因此,研究出具有显著CRF受体结合活性且能拮抗CRF受体生物学活性的小分子仍然是期望的目标。上述CRF受体拮抗剂可用于治疗内分泌、精神病和神经病症或疾病,一般包括应激相关疾病。
虽然通过施用CRF受体拮抗剂来实现CRF调节已取得重大进展,但本领域仍需要有效的小分子CRF受体拮抗剂。还需要含有所述CRF受体拮抗剂的药物组合物以及与其用于治疗诸如应激相关疾病的用途有关的方法。本发明满足上述需要并具有其它相关优点。
本发明尤其涉及新化合物,该新化合物是促肾上腺皮质激素释放因子(CRF)受体的有效和特异的拮抗剂。
