摘    要:5-氟脲嘧及其衍生物是目前临床上广泛使用的抗代谢类抗癌药物, 主要适用于消化道癌、乳腺癌、肺癌等, 但具有一定的毒性, 主要表现为骨髓抑制和胃肠道反应。我们以Koenigs-Knorr法和相转催化法合成了5-氟脲嘧啶的两种类型(-N型, -O型)的半乳吡喃糖苷。这些糖苷类化合物在体内糖苷的作用下, 有可能缓慢地分解释放出5-氟脲嘧啶, 降低其毒性, 提高抑瘤效果。

关 键 词:氟脲嘧啶  抗癌药  吡喃糖  相转移催化  糖苷  半乳糖  山东省自然科学基金

Abstract:Two acetyl galactopyranosides 2-O-benzyl-4-O-(2',3',4',6'-tetra-O-acetyl-b-D-galactopyranosyl)-5-fluoro uracil (I) and 2-O-benzyl-3-N-(2',3',4',6'-tetra-O-acetyl-b-D-galactopyranosyl)-5-fluoro uracil (II) were synthesized by the reaction of 2-O-benzyl-5-fluorouracil and a-acetobromogalactose (III). Under phase transfer catalysis I was also synthesized by the reaction of silver salt of 2-O-benzyl-5-fluorouracil and III. I and II were treated with ammonia in MeOH to obtain deacetylated galactopyranosides, which were hydrogenated in the presence of 10% Pd-C catalyst to obtain galactopyranosides of 5-fluorouracil, IV and V resp.
Keywords:5-fluorouracil  synthesis  galactopyranoside  phase transfer catalysis
