A series of novel 4-chlorophenyl N-alkyl phosphoramidates of 3′-azido-2′,3′-dideoxy-5-fluorouridine (12–21) were synthesized by means of phosphorylation of 3′-azido-2′,3′-dideoxy-5-fluorouridine (4) with 4-chlorophenyl phosphoroditriazolide (10) followed by a reaction with the appropriate amine. The synthesized phosphoramidates (12–21) were evaluated for their cytotoxic activity in three human cancer
一系列新颖的4-氯苯基的Ñ的3'-叠氮基2 -烷基氨基磷酸酯',3'-二脱氧-5-氟尿苷(12 - 21)由3'-叠氮基-2的磷酸化的方法合成',3' -二脱氧-5-氟尿嘧啶(4)与4-氯苯基二三唑啉(10),然后与适当的胺反应。合成氨基磷酸酯(12 - 21使用磺酰罗丹明B(SRB)测定子宫颈(HeLa细胞),口服(KB)和乳癌(MCF-7):)在三种人癌细胞系对它们的细胞毒活性进行评价。在所有研究的癌细胞中,最高的活性是由氨基磷酸亚胺13与N一起显示的。-乙基取代基及其活性远高于母体核苷。在所有使用的细胞系中,具有N-炔丙基取代基的氨基磷酸酯17也表现出良好的活性。
