those of the synthesis of 2 except for the use of MeONa as a base. Compounds (4) were prepared from 1 by treatment with alkyl bromides in the presence of 18-crown-6 in dioxane-aqueous KOH solution. N6,2'-O-Dibenzyl cAMP (3e) was obtained from 1 by the same method as the preparation of 4. These new alkylated derivatives were evaluated for cardiotonic activity in vitro. Some of them showed weak positive
研究了3',5'-环磷酸腺苷(cAMP,1)与烷基溴的烷基化反应,并开发了各种新的烷基化cAMP衍生物N6,N6,2'-O-三烷基cAMP(2),N6,2'-通过一步反应制备O-二烷基cAMPs(3)和2'-O-烷基cAMPs(4),而无需在1中引入保护基。化合物(2)由1通过在烷基溴化物中处理而合成。 NaH或叔丁醇钾在二甲基亚砜中的存在。在使用MeONa作为碱的条件下,化合物(3)也在类似于2的合成条件下由1合成。通过在二恶烷-KOH水溶液中在18-冠-6存在下用烷基溴处理从1制备化合物(4)。通过与制备4相同的方法从1获得N6,2'-O-二苄基cAMP(3e)。评估了这些新的烷基化衍生物的体外强心活性。其中一些表现出弱的正性变力作用和强烈的负变时性作用。因此,对于由cAMP衍生物引起的强力正性肌力活性的出现,2'-羟基的存在似乎是必不可少的。
