The toxicity and tumor affinity of 5-fluorouracil (1) have been modified by the introduction of acyloxyalkyl group (s) at the 1-, 3- or 1, 3-position (s) of 1. 1-Acyloxyalkyl-5-fluorouracil (3), 3-acyloxyalkyl-5-fluorouracil (4) and 1, 3-bis (acyloxyalkyl)-5-fluorouracil (5) were obtained by three methods : i) the reaction of α-chloroalkyl carboxylate (2) with 1, ii) the reaction of alkylidene diacylate with 2, 4-bis (trimethylsilyloxy)-5-fluoropyrimidine, iii) partial hydrolysis of 5. Compounds 3, 4 and 5 showed antitumor activity.
通过在 5-氟尿嘧啶(1)的 1-、3-或 1,3-位(s)上引入酰氧基烷基(s),5-氟尿嘧啶(1)的毒性和肿瘤亲和力得到了改变。1-Acyloxyalkyl-5-fluorouracil (3)、3-acyloxyalkyl-5-fluorouracil (4) 和 1,3-bis (acyloxyalkyl)-5-fluorouracil (5) 是通过以下三种方法获得的:i) α-Cloroalkyl carboxylate (2) 与 1 的反应;ii) 亚烷基二乙酸酯与 2,4-bis (trimethylsilyloxy)-5-fluoropyrimidine 的反应;iii) 5 的部分水解。化合物 3、4 和 5 具有抗肿瘤活性。
