series of 2-alpha-L-rhamnopyranosylnitro[1,2,4]triazolo[1,5-a] pyridine C-nucleosides was synthesized from the condensation oa thioiminoether with nitro-2-pyridylhydrazines. Catalytic reduction afforded the corresponding amino derivative. A 1',2' unsaturated C-nucleoside was also obtained by two different routes. Selective oxidation gave the 3'- and 4'-ketonucleosides. The cytotoxic properties of the
从巯基亚氨基醚与硝基-2-吡啶基肼的缩合反应中合成了一系列2-α-L-鼠李糖基吡咯并硝基[1,2,4]三唑并[1,5-a]吡啶C-核苷。催化还原得到相应的氨基衍生物。还通过两种不同途径获得了1',2'不饱和C-核苷。选择性氧化得到3'-和4'-酮核苷。描述了核苷的细胞毒性特性,以及它们对病毒转化和复制的影响。硝基衍生物抑制病毒复制,但有毒剂量。酮基功能的引入导致产物在非细胞毒性浓度下抑制鼠白血病病毒(MuLV)的复制。氨基衍生物没有明显的抗病毒作用。
