yethoxy)methyl]purines. The bases synthesized were inhibitors of DNA polymerase alpha isolated from Chinese hamster ovary cells, the most potent compounds being 6-methoxy and 6-methylthio derivatives of 2-(p-n-butylanilino)purine. When tested for their ability to inhibit [3H]thymidine incorporation into DNA in HeLa cell cultures and the growth of exponentially growing HeLa cells, 9-(2-deoxy-beta-D-ribofuranosyl)
合成了N2-(pn-丁基苯基)鸟嘌呤(BuPG)和2-(pn-丁基苯胺基)腺嘌呤(BuAA)的衍生物,并测试了它们作为哺乳动物DNA聚合酶α,细胞生长和大分子合成的抑制剂。2-(pn-Butylanilino)-6-氯嘌呤(BuACl)用作制备一系列6取代类似物的有用中间体。BuACl的钠盐与2-乙氧基3,5-二-对甲苯甲酰基-β-D-呋喃呋喃糖基氯在乙腈中反应,得到64%的相应9-β核苷(封端的BuAdCl)和仅14% 7-β异构体 在BuAdCl中对氯进行解封和取代生成了一系列2-(pn-丁基苯胺基)-9-(2-脱氧-β-D-核呋喃糖基)嘌呤衍生物。解封并取代6-氯基团后,BuACl的钠盐与(2-乙酰氧基乙氧基)甲基溴反应,一系列的2-(pn-丁基苯胺基)-9-[(2-羟基乙氧基)甲基]嘌呤。合成的碱基是从中国仓鼠卵巢细胞中分离的DNA聚合酶α的抑制剂,最有效的化合物是2-(pn-丁基
