Sažetak
A series of the novel acyclic unsaturated pyrimidine (1–12) and adenine (13) nucleoside analogues bearing conformationally restricted (Z)-2'-butenyl moiety were synthesized to evaluate their antiviral and cytostatic activity potency against malignant tumor cell lines and normal human fibroblast (WI38). The N-1 and/or N-3 acyclic side chain substitution in pyrimidine ring in N-3 substituted 5-trifluoromethyluracyl derivative (11), N-1, N-3 disubstituted 5-fluorouracyl derivative (12) and adenine derivative (13) was deduced from their 1H and 13C NMR spectra and confirmed by single crystal X-ray structure analysis. The X-ray crystal structure analysis 11-13 revealed also supramolecular self-assemblies that built infinite chains into two- and three–dimensional networks. The results of the in vitro cytostatic activity evaluations of 1-13 indicate that majority of the tested compounds exhibited a non-specific and moderate antiproliferative effect at the highest concentration (100 μM). Of all evaluated compounds on the tested cell lines only N-1-4'' fluoro-substituted-benzamide uracyl derivative (7) showed rather marked and selective inhibitory activity against the growth of MCF-7 cells at concentration of 2.7 µM and no cytotoxic effect on normal fibroblasts WI38. This compound can be therefore considered as potential lead compound for further synthetic structure modification.
