A number of N-acyl and N-(alkoxycarbonyl)-5-fluorouracil derivatives possessing, for example, benzoyl, o-toluyl, acetyl, propionyl, heptanoyl, ethoxycarbonyl, phenoxycarbonyl, and benzyloxycarbonyl groups as N1 and/or N3 substituents were synthesized, and their antitumor activities were evaluated. The synthesis was achieved by a direct and two-step acylation of 5-fluorouracil and by selective N1-deacetylation
合成了许多具有例如N 1和/或N 3取代基的苯甲酰基,邻甲苯甲酰基,乙酰基,丙酰基,庚酰基,乙氧基羰基,苯氧基羰基和苄氧基羰基的N-酰基和N-(烷氧基羰基)-5-氟尿嘧啶衍生物。 ,并评估了它们的抗肿瘤活性。通过在适当的反应条件下对5-氟尿嘧啶进行直接和两步酰化,以及对N1-乙酰基-N3-取代的5-氟尿嘧啶进行选择性的N1-脱乙酰化,可以实现合成。几种N3-苯甲酰基-和N3-邻甲苯基-5-氟尿嘧啶衍生物具有显着的抗实验肿瘤活性,并且发现其中N1-乙酰基-N3-邻甲苯基-5-氟尿嘧啶是最有前途的。进一步的调查显示,与1或FT-207相比,12可以保留对各种肿瘤更高的活性,并且毒性更低,血液水平更高。
