Eighteen substituted 2,5-bis(4-guanylphenyl)furans and related analogues, including "masked" amidines in which the guanyl function is incorporated into a heterocyclic ring, have been synthesized and their antimalarial and antitrypanosomal activity has been evaluated. None of the compounds exhibited high orders of antimalarial activity; however, 11 were very active against Trypanosoma rhodesiense in
已经合成了十八个取代的2,5-双(4-胍基苯基)呋喃和相关类似物,包括其中将胍基功能结合到杂环中的“掩蔽的” am,并且已经评估了它们的抗疟和抗锥虫活性。这些化合物均未显示出高水平的抗疟活性。但是,有11种在小鼠中对罗氏锥虫有很高的活性。六种化合物,包括2,5-双(4-胍基苯基)呋喃(4)及其3-氯(32),3,4-二氯(31),3-甲基(25),3,4-二甲基(20 )和3-氯-4-甲基(38)衍生物在小鼠体内以亚毫克剂量水平产生治愈作用; 3,4-二甲基(20)类似物表现出延长的治疗效果,单次给药后可提供30天的保护,以抵抗罗德氏梭菌的攻击。这六个化合物在该筛选中的活性比stilbamidine,hydroxystilbamidine和pentamidine更高。通常,“被掩盖的” am比其真正的鸟嘌呤对应物显示出更低的抗胰蛋白酶活性。由1,4-二-对溴苯基-1,4-丁二酮经环脱水呋喃合成2
