A simple method for the synthesis of various purine arabinosides from purine bases and uracil arabinoside by microbial transarabinosylation is described. A wet cell paste of Enterobacter aerogenes AJ 11125 showed a wide substrate specificity range for purine bases. Not only naturally occurring purine bases such as adenine and hypoxanthine but also unnatural bases such as 6-thioguanine and 2-chlorohypoxanthine were catalyzed to give the corresponding purine arabinosides. The enzymatically synthesized purine arabinosides were isolated from the reaction mixtures and identified by physicochemical means. The biological activities of the compounds were investigated and it was found that thioguanine arabinoside and 2-methyladenine arabinoside have potent activity against Hela cells, and their ED50 were 10.5 and 21.5 μg/ml, respectively.
描述了一种通过微生物反转阿拉伯糖基化法合成各种嘌呤阿拉伯糖苷的简单方法。Enterobacter aerogenes AJ 11125 的湿细胞浆对嘌呤碱具有广泛的底物特异性范围。不仅天然存在的嘌呤碱如腺嘌呤和次黄嘌呤,而且不自然的碱基如6-巯基鸟嘌呤和2-氯次黄嘌呤也被催化生成相应的嘌呤阿拉伯糖苷。酶合成的嘌呤阿拉伯糖苷从反应混合物中分离出来,并通过物理化学方法鉴定。这些化合物的生物活性进行了研究,发现巯基鸟嘌呤阿拉伯糖苷和2-甲基腺嘌呤阿拉伯糖苷对Hela细胞具有强效活性,它们的ED50分别为10.5和21.5 μg/ml。
