Description

3-[(苯并[d][1,3]二氧戊环-4-基)-氧基]-3-芳基丙胺类化合物及其应用 技术领域
本发明属于药物化学领域,具体涉及一种3-[(苯并[d][1,3]二氧戊环-4-基)-氧基]-3-芳基丙胺类化合物及其应用。
技术背景
抑郁症是当今最常见的危害人类身心健康的精神疾病。目前全世界抑郁症患者已占世界人口的3-5%。预计到2020年,抑郁症可能将成为仅次于心脏病的第2大疾病。
药物治疗是抑郁症治疗的主要手段。主要治疗药物包括:三环类抗抑郁药,如丙咪嗪等;单胺氧化酶抑制剂,如吗氯贝胺等;选择性5-HT再摄取抑制剂,如氟西汀等;选择性NE再摄取抑制剂,如波瑞西汀等;5-HT及NE双重再摄取抑制剂,如度洛西汀等。
尽管已有不少抗抑郁药物用于临床,但由于某些药物反应率低,起效时间长,并有潜在的副作用,因此仍有相当的病人对各种治疗是无效的,有的甚至需求助于电惊厥治疗。因此抗抑郁药的开发仍是新药研究的热点。
US 4018895公开了包括氟西汀在内的如下结构所示的抗抑郁药:
Figure PCTCN2015098641-appb-000001
其中,Ar为萘环或取代的苯环,R1和R2分别为H或甲基。
CN 1019113公开了包括度洛西汀在内的如下结构的抗抑郁药物:
Figure PCTCN2015098641-appb-000002
其中Ar为萘环或取代的苯环,Ar1为环烷基、呋喃基、噻吩基或噻唑基,R1和R2分别为H或CH3
CN 101613347公开了包括阿姆西汀在内的如下结构的抗抑郁化合物:
Figure PCTCN2015098641-appb-000003
其中,X为O或S,R1和R2各自独立地代表H或C1-C3烷基。
虽然上述度洛西汀、阿姆西汀等药物的抗抑郁活性较好,但其结构对酸不稳定,在胃中易分解,不利于药物在胃内崩解吸收,不适宜制备普通片剂,对于制剂有较高的选择性。
