easily prepared via its corresponding phosphinimine derivative, by zinc chloride catalyzed reaction of the corresponding acyl chlorides RCOCl (a–f) gave the protected N-acyl-β-d-glucopyranosylureas (6a–f), in acceptable-to-moderate yields. Subsequent deacetylation of analogues 6a–f under Zemplén conditions afforded the fully deprotected derivatives 7a,b,d,e,f, while the desired urea 7c was formed after
已经合成了新型的乙酰化和完全脱保护的N-酰基-β - d-吡喃葡萄糖胺和脲,并对其进行了生物学评估。所述per-酰化ö -acetylated β - d -glucopyranosylurea(5),通过其相应的膦亚胺衍生物容易地制备,通过相应的酰基氯的RCOCl氯化锌催化反应(一- ˚F),得到被保护的Ñ -acyl- β - d-吡喃葡萄糖基尿素(6a – f),产率中等至可接受。随后的类似物脱乙酰化在Zemplén条件下,图6a - f提供了完全脱保护的衍生物7a,b,d,e,f,而所需的脲7c在用二丁基氧化锡处理6c后形成。检查了所有受保护和未受保护的化合物在不同的L1210,CEM和HeLa肿瘤细胞系中的细胞毒性活性,并且还针对各种DNA和RNA病毒进行了评估。衍生物7c对三种评估的肿瘤细胞系(IC 50 9–24μM)表现出细胞抑制活性,并且可能是合成具有改善细胞抑制潜能的结构相关衍生物的基础。仅模拟6f
