Structure‐activity relationships of homopiperazine‐containing alkoxybiaryl nitriles employing various D‐amino acid moieties and their N‐furanoyl analogues were undertaken. This led to A‐320436, a potent and selective non‐imidazole H3‐receptor antagonist possessing balanced affinity for both rat and human H3‐receptors. This compound was shown to demonstrate in vitro and in vivo functional antagonism
研究了使用各种 D-氨基酸部分的高哌嗪烷氧基联芳腈及其 N-呋喃酰基类似物的结构-活性关系。这导致了 A-320436,一种有效且选择性的非咪唑 H3-受体拮抗剂,对大鼠和人类 H3-受体具有平衡的亲和力。该化合物显示出体外和体内功能拮抗作用,并且在一般观察试验中,剂量 (ip) 高达 163 mg/kg 时无神经毒性。
