Deskripsi
A novel series of 2-arylalkylthio-5-iodine-6-substitutedbenzyl-pyrimidine-4(3H)-ones (S-DABOs) 8a–x had been synthesized via an efficient method. Their biological activity against HIV virus and RT assay were evaluated. Some compounds, especially 8h, 8l and 8n, displayed promising activity against HIV-1 RT with IC50 values in a range of 0.41 μM to 0.71 μM, which were much better than that of nevirapine. Molecular modeling studies revealed that the binding mode would be affected via forming an additional hydrogen bond by incorporating an oxygen atom on the C-2 side chain. The biological activity was in accordance with the docking results.
