A series of 2‐, 4‐ or 2‐methyl‐6‐substituted xanthone derivatives 8–17 containing selected piperazine moieties were synthesized and tested for their electrocardiographic, anti‐arrhythmic, and antihypertensive activity, as well as for the α1‐ and β1‐adrenoceptor binding affinities. Of the newly synthesized derivatives, 2‐(2‐hydroxy‐3‐(4‐(2‐phenoxyethyl)piperazin‐1‐yl)propoxy)‐9H‐xanthen‐9‐one dihydrochloride
合成了一系列含有选定哌嗪部分的 2-、4- 或 2-甲基-6- 取代的呫吨酮衍生物 8-17,并测试了它们的心电图、抗心律失常和抗高血压活性,以及 α1- 和 β1 -肾上腺素受体结合亲和力。在新合成的衍生物中,2-(2-羟基-3-(4-(2-苯氧基乙基)哌嗪-1-基)丙氧基)-9H-黄原素-9-一二盐酸盐9、4-(2-羟基-3 -(4-(2-苯氧基乙基)哌嗪-1-基)丙氧基)-9H-黄原胶-9-一二盐酸盐12,和4-(2-(4-(吡啶-2-基)哌嗪-1-基)乙氧基)-9H-黄原胶-9-一二盐酸盐15在肾上腺素诱发的心律失常模型中具有显着的抗心律失常活性,ED50值为1.7-7.2mg/kg。化合物 15 的最低 ED50 值等于 1.7 mg/kg,与普萘洛尔的 ED50 值相当,在本试验中用作参考化合物。化合物9也表现出最强的降压活性,在2.5mg/kg的剂量下持续60分钟。2- (2-
