Synthesis, cytostatic and anti-HIV evaluations of the new unsaturated acyclic C-5 pyrimidine nucleoside analogues
A series of the novel C-5 alkynyl pyrimidine nucleoside analogues (1-14) in which the sugar moiety was replaced by the conformationally restricted Z- and E-2-butenyl spacer between the phthalimido and pyrimidine ring were synthesized by using Sonogashira cross-coupling reaction. Cytostatic activity evaluation of the novel compounds showed that E-isomers exhibited, in general, better cytostatic activities than the corresponding Z-isomers. E-isomer 14 exhibited the best cytostatic effect against all evaluated malignant cell lines, particularly against hepatocellular carcinoma (Hep G2, IC50 = 4.3 uM). However, this compound was also cytotoxic to human normal fibroblasts (WI 38). Its Z- isomer 7 showed highly specific antiproliferative activity against Hep G2 (IC50 = 18 uM) and no cytotoxicity to WI 38. Moreover, compounds 3, 4 and 14 expressed some marginal inhibitory activity against HIV-1 and HIV-2.
