2-(N-beta-D-glucopyranosyl)aminothiazole-4-carboxylate, and ammonolysis led to the corresponding 4-carboxamide. Antimicrobial screening against five microorganisms showed that N-(2,3,5-tri-O-acetyl-beta-D-ribofuranosyl)rhodanine and the glucosylaminothiazole-4-carboxylate had the broadest spectrum of inhibitory activity, although the thioureas usually showed inhibition of some organisms.
在N-(2,3,4,6-四-O-乙酰基-β-D-吡喃葡萄糖基)-5-芳烷基亚乙基内酯的氨解中发现了一种获得N-β-D-吡喃葡萄糖基硫脲的方法。尽管使用吗啉和羟胺获得了N-(2,3,5-三-O-苯甲酰基-β-D-呋喃呋喃糖基)硫脲,但是三乙酰化或三苯甲酰化的核糖基罗丹宁的氨解通常不会产生核糖基硫脲,但会导致糖苷裂解。用溴丙酮酸乙酯对N-β-D-吡喃葡萄糖基硫脲进行环封闭,得到2-(N-β-D-吡喃葡萄糖基)氨基噻唑-4-羧酸乙酯,并且氨解反应产生相应的4-羧酰胺。对五种微生物的抗菌素筛选表明,N-(2,3,5-三-O-乙酰基-β-D-呋喃呋喃糖基)罗丹宁和葡糖基氨基噻唑-4-羧酸酯具有最广谱的抑制活性,
