Modification at the 5' position yielded the deoxy, iodo, and phosphate derivatives 15, 13, and 16, as well as the cyclic 3',5'-phosphate 17. The synthesis of the C-nucleoside analogue 19 was achieved from the beta-D-ribofuranosylcarboximidic ester 20. The acyclic analogue 29 and the beta-D-arabinofuranosyl derivative 35 were both synthesized by reaction of methyl isocyanate with the appropriately protected
在肌肉松弛剂,心血管,抗炎和抗过敏试验中,评估了具有药理活性的海洋天然产物1-甲基异鸟苷(1)的一系列类似物的生物活性。在1位上的修饰分别产生乙基,正丁基,正辛基和苯基衍生物3-6。在8位的取代提供了溴,肼和氨基化合物9-11。在5'位的修饰产生了脱氧,碘和磷酸盐衍生物15、13和16,以及环状3',5'-磷酸盐17。C-核苷类似物19的合成由β完成-D-呋喃核糖基羧酰亚胺酯20。无环类似物29和β-D-阿拉伯呋喃糖基衍生物35都是通过异氰酸甲酯与适当保护的氨基氰咪唑前体28和32反应合成的。1-甲基黄嘌呤(12),异鸟苷(7)和2-甲氧基腺苷(18)。也被合成。在高达100 mg / kg po的剂量下,5'-磷酸16,环状3',5'-磷酸17和O-甲基化的类似物2-甲氧基腺苷18在产生肌肉松弛和体温过低方面具有活性。这些化合物具有抗过敏活性,并且与1-乙基(3)和1-正丁基(4)类似物
