A hydroxylated metabolite of 1-(tetrahydro-2-furanyl)-5-fluorouracil (FT), 1-(trans-3-hydroxytetrahydro-2-furanyl)-5-fluorouracil (trans-3'-OH-FT, VIII) and its isomer, 1-(cis-3-hydroxytetrahydro-2-furanyl)-5-fluorouracil (cis-3'-OH-FT, VI), were synthesized and isolated at high purity. As compounds related to FT metabolites, 2, 3'-anhydro-1-(cis-3-hydroxytetrahydro-2-furanyl)-5-fluorouracil (2, 3'-anhydro-FT, V), 1-(2, 5-dihydro-2-furanyl)-5-fluorouracil (3', 4'-dehydro-FT, XII) and 1-(5-acetoxytetrahydro-2-furanyl)-5-fluorouracil (5'-AcO-FT, XI) were also synthesized. The antitumor activities of these compounds against sarcoma 180 and L 1210 were examined. The activities of cis-3'-OH-FT (VI) and 2, 3'-anhydro-FT (V) were found to be lower than that of FT. The activity of 5'-AcO-FT (XI) was the same as that of FT. 3', 4'-Dehydro-FT (XII) showed much greater activity than FT.
合成并分离出了 1-(四氢-2-呋喃基)-5-氟尿嘧啶(FT)的羟基代谢产物 1-(反式-3-羟基四氢-2-呋喃基)-5-氟尿嘧啶(反式-3'-OH-FT,VIII)及其异构体 1-(顺式-3-羟基四氢-2-呋喃基)-5-氟尿嘧啶(顺式-3'-OH-FT,VI),其纯度很高。作为 FT 代谢物的相关化合物,2, 3'-脱水-1-(顺式-3-羟基四氢-2-呋喃基)-5-氟尿嘧啶(2, 3'-脱水-FT,V)、1-(2、还合成了 1-(2,5-二氢-2-呋喃基)-5-氟尿嘧啶(3',4'-脱氢-FT,XII)和 1-(5-乙酰氧基四氢-2-呋喃基)-5-氟尿嘧啶(5'-AcO-FT,XI)。研究了这些化合物对肉瘤 180 和 L 1210 的抗肿瘤活性。发现顺式-3'-OH-FT(VI)和 2,3'-脱水-FT(V)的活性低于 FT。5'-AcO-FT (XI) 的活性与 FT 相同。3',4'-脱氢-FT(XII)的活性远高于 FT。
