Glucosidation of some 4-amino- and 4-arylideneamino-5-(pyridin-3-yl)-2,4-dihydro-[1,2,4]-triazole-3-thiones with 2,3,4,6-tetra-O-acetyl-alpha-D-glucopyranosyl bromide followed by chromatographic separation gave the corresponding N- and S-beta-D-glucosides. The structure of these two regiosiomers was established chemically and spectroscopically. Deamination as well as deacetylation of some selected nucleosides
一些4-氨基和4-亚芳基氨基-5-(吡啶-3-基)-2,4-二氢-[1,2,4]-三唑-3-硫酮与2,3,4,6-的葡萄糖苷化四-O-乙酰基-α-D-吡喃葡萄糖基溴化物,然后色谱分离,得到相应的N-和S-β-D-葡萄糖苷。这两种区域异构体的结构是通过化学和光谱学方法确定的。已经实现了一些选定核苷的脱氨基以及脱乙酰化。对14种选定化合物的抗微生物筛选导致其对烟曲霉,意大利青霉菌,总青霉,白念珠菌,金黄色葡萄球菌,铜绿假单胞菌,枯草芽孢杆菌和大肠杆菌具有活性。
