Synthesis and antitumor evaluation in mice of certain 7-deazapurine (pyrrolo[2,3-d]pyrimidine) and 3-deazapurine (imidazo[4,5-c]pyridine) nucleosides structurally related to sulfenosine, sulfinosine, and sulfonosine

mice, none of these nucleosides exhibited biologically significant activity (T/C greater than or equal to 125). Even so, antileukemic activity appeared to be influenced, albeit not uniformly, by structural modifications in the base and carbohydrate moieties of sulfenosine and sulfinosine. Thus, while several of the compounds were lacking in cytotoxic activity, eight others (4c, 5a, 5c, 6a, 6b, 7b,
7-Deaza(吡咯并[2,3-d]嘧啶)和3-deaza(咪唑并[4,5-c]吡啶)的同类产品,分别为亚磺酰基(5a和9),亚磺酰基(6a和10)和磺基磺酸(7a)。已经制备并评估了它们在小鼠中的抗白血病活性。用氯胺溶液胺化2-氨基-7-β-D-呋喃呋喃糖基吡咯并[2,3-d]嘧啶-4(3H)-th离子e(4a)及其2'-脱氧类似物(4c),得到相应的4-亚磺酰胺(分别为5a和5c),经间氯过氧苯甲酸(MCPBA)选择性氧化后,分别得到非对映异构体2-氨基-7-β-D-呋喃呋喃糖基-吡咯并[2,3-d]嘧啶-4 -亚磺酰胺(7-脱氮杂亚磺酸,6a)及其2'-脱氧衍生物(6c)。7-(2-脱氧-β-D-赤型-五呋喃糖基)吡咯并[2,3-d]嘧啶-4(3H)-硫酮的类似胺化作用(4b)得到相应的4-亚磺酰胺衍生物(5b)。用1摩尔当量的MCPBA氧化5b所提供的(R,S)-7-(2-脱氧-β-D-赤型五呋喃糖基)吡咯并[2
