for alpha 2- and alpha 1-adrenoceptor antagonist activity on the rat vas deferens and anococcygeus muscle, respectively. A number of compounds in this series were shown to be potent and selective alpha 2-adrenoceptor antagonists. Studies on the resolved enantiomers of compounds 6, 10, and 16 showed that alpha 2-adrenoceptor antagonist activity resided primarily in the 2R,11bS isomers, related to the absolute
合成了一系列的2-磺酰胺基-1,3,4,6,7,11bα-六氢-2H-苯并[a]喹啉并研究了α2-和α1-肾上腺素受体拮抗剂对大鼠输精管和血管的活性。棘球muscle肌。已显示该系列中的许多化合物是有效的选择性α2-肾上腺素受体拮抗剂。对化合物6、10和16的拆分对映异构体的研究表明,α2-肾上腺素受体拮抗剂活性主要存在于2R,11bS异构体中,与α2-拮抗剂育亨宾的绝对构型有关,例如苯环和磺酰胺该系列中的基团可与育亨宾的吡咯和酯基重叠。
