A new class of selective vasopressin receptor 1A (V1A) antagonists was identified, where “methyl-scan” was performed around the benzene ring of the 5-hydroxy-triazolobenzazepine core. This led to the synthesis of two 10-methyl derivatives, each possessing a chiral axis and a stereogenic center. The four atropisomeric stereoisomers (involving two enantiomer pairs and atropisomeric diastereomers) could
确定了一类新的选择性加压素受体 1A (V 1A ) 拮抗剂,其中“甲基扫描”是在 5-羟基-三唑并苯并氮杂核心的苯环周围进行的。这导致合成了两种 10-甲基衍生物,每种衍生物都具有手性轴和立体中心。可以成功地分离和光谱表征四种阻转异构体(包括两个对映异构体对和阻转异构体非对映异构体)。根据这些化合物的体外药理学特征,人 V 1A受体对具有R轴手性的异构体有强烈的偏好,最活跃的异构体是 a R ,5 S异构体。此外,异构体和新合成的类似物的构效关系可以通过计算机研究初步解释。
