All the synthesized compounds were in vitro evaluated for their inhibitory effect against the HIV-1 replication in the MT-4 cells. Results showed that none of these synthesized compounds displayed any specific anti HIV-1 activity. Surprisingly, these compounds showed high cytotoxicity against MT-4 cells with low selectivity index (<1), therefore could be new potential antiproliferative agents. Therefore, their antiproliferative property were evaluated against MOLM-13 and K562 (leukemia) cell lines. Compound 14g showed notable antitumor activity toward both studied cell lines (EC50 = 1.3 μM and EC50 = 1.8 μM respectively).Graphical abstractA series of novel 2-((5-substituted-4-nitro-1H-imidazol-1-yl)methyl)-5-hydroxy-1-methylpyridin-4(1H)-one were prepared and their anti-HIV-1 activity was evaluated. Because of high cytotoxicity against MT-4 cells, none of them were active toward HIV-1. However, they displayed promising antiproliferative ...
