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 &agr;1B adrenoceptor antagonists composed of these substances. The invented compounds are antagonists having high affinity for &agr;1B adrenoceptor and are useful as pharmaceutical agents for use in prophylaxis/therapy of diseases (e.g., hypertension) in which &agr;1B adrenoceptor is involved or as pharmacological tools for elucidation of physiological activities mediated by &agr;1B adrenoceptor.
提供的化合物由一般式(I)表示:[其中Ar是吲哚等,R1是氢等,B是键,或者B-N-R1形成环结构且是哌啶等,n为0、1等,A是三亚甲基、丁二烯等,Q是哌啶、异吲哚等],或其药理学上可接受的酸盐,以及由这些物质组成的α1B肾上腺素受体拮抗剂。这些发明的化合物是对α1B肾上腺素受体具有高亲和力的拮抗剂,可用作预防/治疗与α1B肾上腺素受体有关的疾病(例如高血压)的药物代理,或作为阐明α1B肾上腺素受体介导的生理活动的药理学工具。
