N-(methoxy-(S)-alaninyl) substituents, respectively, displayed remarkable activity in all the investigated cancer cells, and the activity was considerably higher than that of the parent nucleoside 4 and FdU. Among phosphoramidates 10a-10j compound 10c with the N-(2,2,2-trifluoroethyl) substituent showed the highest activity. Phosphoramidate 10c was more active than the FdU in all the cancer cell lines tested.
3'-O-(叔丁氧基羰基)-5-氟-2'-脱氧尿苷(3'-BOC-FdU)(9a-9j)和5-氟-2的两个系列的新的4-氯苯基N-烷基氨基磷酸酯通过将3'-BOC-FdU(4)与4-氯苯基二三唑基磷酸酯(7)进行磷酸化反应,合成'-脱氧尿苷(FdU)(10a-10j)。通过在酸性条件下除去3'-叔丁氧羰基保护基(BOC),将氨基磷酸酯9a-9j转化为相应的10a-10j。评估了合成的氨基磷酸酯9a-9j和10a-10j在五种人类癌细胞系中的细胞毒性活性:宫颈癌(HeLa),鼻咽癌(KB),乳腺癌(MCF-7),肝脏(HepG2),骨肉瘤(143B)和正常人皮肤成纤维细胞系(HDF),使用磺基罗丹明B(SRB)分析。分别具有N-乙基和N-(甲氧基-(S)-丙氨酸基)取代基的两个氨基磷酸酯9b和9j在所有研究的癌细胞中均显示出显着的活性,并且该活性明显高于亲本核苷4和9的活性。 FdU。在氨基磷酸酯10a-10j中,具有N-(2
