There are provided compounds represented by the general formula (I):
[wherein Ar is indole etc., R1 is hydrogen etc., B is bond, or B-N-R1 forms a ring structure and is piperidine etc., n is 0, 1, etc., A is trimethylene, butylene, etc., Q is piperidine, isoindoline, etc.], or pharmacologically acceptable acid addition salts thereof, and α1B adrenoceptor antagonists composed of these substances. The invented compounds are antagonists having high affinity for α1B adrenoceptor and are useful as pharmaceutical agents for use in prophylaxis/therapy of diseases (e.g., hypertension) in which α1B adrenoceptor is involved or as pharmacological tools for elucidation of physiological activities mediated by α1B adrenoceptor.
提供了通式(I)所代表的化合物:
[其中Ar为
吲哚等,R1为氢等,B为键,或B-N-R1形成环状结构且为
哌啶等,n为0、1等,A为三亚甲基、
丁烯等,Q为
哌啶、
异吲哚啉等],或其药理学上可接受的酸加成盐,以及由这些物质组成的α1B
肾上腺素受体拮抗剂。本发明化合物是对α1B
肾上腺素受体具有高亲和力的拮抗剂,可作为药物制剂用于预防/治疗涉及α1B
肾上腺素受体的疾病(如高血压),或作为药理学工具用于阐明α1B
肾上腺素受体介导的生理活动。
