A series of 5-fluorouracil derivatives having (alkylthio) carbonyl groups at the 1-, 3-, and 1, 3-positions was synthesized and tested for antitumor activity against L-1210 leukemia in mice. Among them, 1-(octylthio) carbonyl-5-fluorouracil showed promising activity ; it gave a greater increase in life span than 1-hexylcarbamoyl-5-fluorouracil (HCFU) and 1-(2-tetrahydrofuryl)-5-fluorouracil (Tegafur), which are both in clinical use.
合成了一系列在1、3位和1,3位具有(烷基硫)羰基的5-氟尿嘧啶衍生物,并测试了其对小鼠L-1210白血病的抗肿瘤活性。其中,1-(辛基硫)羰基-5-氟尿嘧啶表现出良好活性;其延长的生存期超过了临床使用的1-己基氨基-5-氟尿嘧啶(HCFU)和1-(2-四氢呋喃基)-5-氟尿嘧啶(Tegafur)。
