The synthesis and cytostatic activity of several chloromethyl- and iodomethylpyrazole nucleosides are described. Glycosylation of ethyl 3(5)-(chloromethyl)pyrazole-5(3)-carboxylate (3) and 3(5)-(chloromethyl)pyrazole-5(3)-carboxamide (4) with poly(O-acetylated) sugars via an acid-catalyzed fusion method gave the corresponding 3-(chloromethyl)-5-carboxylate and 3-(chloromethyl)-5-carboxamide substituted
描述了几种氯甲基-和碘甲基吡唑核苷的合成和细胞抑制活性。3(5)-(氯甲基)吡唑-5(3)-羧酸乙酯(3)和3(5)-(氯甲基)吡唑-5(3)-羧酰胺(4)与聚(O-乙酰化)糖的糖基化通过酸催化的融合方法,分别得到相应的3-(氯甲基)-5-羧酸酯和3-(氯甲基)-5-羧酰胺取代的核苷7和9。从4与四-O-乙酰基-β-D-呋喃呋喃糖的反应,也获得了5-(氯甲基)-3-羧酰胺取代的衍生物11。7、9和11与碘化钠在丙酮中的反应提供了相关的碘甲基吡唑核苷8、10和12。通常,氯甲基取代的核苷酸对HeLa细胞显示中等活性,而所有相应的碘甲基衍生物均表现出高活性。这些化合物中的某些增加了患有ECA肿瘤的小鼠的寿命。
