A series of disulfonamidobenzo[a]quinolizines were synthesized and evaluated for their alpha 2- and alpha 1-adrenoceptor antagonist activity on the rat vas deferens and anococcygeus muscle, respectively. N-((2 beta,11b alpha)-1,3,4,6,7,11b-Hexahydro-2H-benzo[a]quinolizin-2-yl)-N- [2-[(methylsulfonyl)amino]ethyl]methanesulfonamide (4) and its N-[2-[(methylsulfonyl)amino]ethyl]ethanesulfonamide (22), N-[2-[(ethylsulfonyl)amino]ethyl]ethanesulfonamide (27), and N-[2-[(methylsulfonyl)amino]ethyl]-4-methylbenzenesulfonamide (30) analogues showed 400-fold or greater selectivity in favor of alpha 2- over alpha 1-adrenoceptor blockade.
合成了一系列二磺酰胺苯并[a]喹嗪，并分别在大鼠输精管和肛尾肌上评估了它们对α2和α1肾上腺素能受体的拮抗活性。N-((2β,11bα)-1,3,4,6,7,11b-六氢-2H-苯并[a]喹嗪-2-基)-N-[2-[(甲基磺酰基)氨基]乙基]甲磺酰胺(4)及其N-[2-[(甲基磺酰基)氨基]乙基]乙磺酰胺(22)、N-[2-[(乙基磺酰基)氨基]乙基]乙磺酰胺(27)和N-[2-[(甲基磺酰基)氨基]乙基]-4-甲基苯磺酰胺(30)类似物在α2肾上腺素能受体阻断方面表现出比α1肾上腺素能受体阻断高400倍或更高的选择性。
