A series of new 5-alkyl-2-benzylsulfanylpyrimidin-4(3H)-ones (5a-y) bearing different substituted arylmethyl moieties at the C-6 position of the pyrimidine core have been synthesized and evaluated for their in vitro activities against HIV-1 and HIV-2 in MT-4 cell cultures. The majority of the title compounds showed moderate to good activities against HIV-1 with an IC50 range from 6.67 μM to 0.12 μM. Among them, 6-(3,5-dimethylbenzyl) analogue 5q exhibited the most potent anti-HIV-1 activity (IC50 = 0.12 μM, SI > 2642), which was about 40-fold more active than the reference compounds 1-[(2-hydroxyethoxy)methyl]-6-(phenylsulfanyl)thymine (HEPT) and 2′,3′-dideoxyinosine (DDI). The structure-activity relationships (SARs) of these new congeners were further discussed.

The present study describes the synthesis and antiviral evaluation of a series of novel 6-(3-trifluoromethylbenzyl) and 6-(fluorobenzyl) analogues of the HIV drugs emivirine and GCA-186. The objective was to investigate whether the fluoro or trifluoromethyl substituents could lead to an improved antiviral activity against HIV-1 wild type and mutants resistant to non-nucleoside RT inhibitors. The biological test results showed that the most of theses compounds showed good activity against wild type HIV-1. Among them, compound 1-(ethoxymethyl)-6-(3-fluorobenzyl)-5-isopropyluracil (9i) showed the largest inhibitory potency (EC50 = 0.02 μM), resulting equally potent than emivirine against wild type HIV-1. Furthermore, compound 9i showed marginal better activity against resistant mutants than emivirine. The key steps in the synthesis of the target compounds were either reaction of an appropriate β-keto ester with thiourea or a cross-coupling reaction of 6-chloro-2,4-dimethoxypyrimidines with benzylic Grignard reagents.
