units exhibited the highest activity among dimers 21–30. The activity of compound 29 was higher than that of dFdC in all the studied cancer cell lines. A similar order of activity was observed for compounds 25, 28, and 30. The best activity among all the dimers synthesized was displayed by compound 39, comprising two gemcitabine units with a cleavable linker. The activity of compound 39 was 5 to 9 times
使用“点击”化学方法合成了两个系列的新型吉西他滨-核苷类似物二聚体。在第一系列二聚体(的21 - 30),该核苷单位用一个稳定的连接methyltriazole 4 Ñ -3'(或5')ç接头,而第二系列(31 - 40)配有一个可裂解的酯,methyltriazole 4 N -3'(或5')C接头。Dimers 21 – 40使用磺基罗丹明,对五种人类癌细胞系(例如宫颈癌(HeLa),鼻咽癌(KB),肺脏(A549),脑(U87),肝脏(HepG2)和正常皮肤成纤维细胞系(HDF)的细胞毒性活性进行了评估。 B(SRB)分析。化合物29包括两个吉西他滨(DFDC)单元表现出最高的活性二聚体中21 - 30。在所有研究的癌细胞系中,化合物29的活性均高于dFdC。观察到的化合物活性的类似的命令25,28,和30。化合物39显示出合成的所有二聚体中最好的活性,包括两个具有可裂解接头的吉西他
