Novel emivirine analogues 6a, b were synthesized by reacting chloromethyl ethyl ether with 5-ethyl/isopropyl-6-(3,5-dimethoxybenzyl)uracils 5e, f. On the other hand, A series of new TNK-651 analogues 10a-f substituted at N-1 with phenoxyethoxymethyl moiety was prepared on treatment of the corresponding uracils 5a-f with bis(phenoxyethoxy)methane (9). The newly synthesized non-nucleosides were tested for antiviral activity against wild type HIV-1 IIIB as well as the resistant strains N119 (Y181C), A17 (K103N+Y181C), and the triple mutant EFVR (K103R+V179D+P225H) in MT-4 cells. Most of the tested compounds showed good activities. Among them 6-(3,5-dimethylbenzyl)-5-ethyl-1-[(2-phenoxyethyl)oxymethyl]uracil (10c) and 6-(3,5-dimethylbenzyl)-5-isopropyl-1-[(2-phenoxyethyl)oxymethyl]uracil (10d) that showed inhibitory potency higher than emivirine against both wild type HIV-1 and the tested mutant strains, as well as higher activity than efavirenz against EFVR.

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.

Ethyl 2-alkyl-4-aryl-3-oxobutyrates were synthesized from the corresponding arylacetonitriles and 2-brome esters. Condensation of the butyrates with thiourea followed by treatment with chloroacetic acid afforded the 5-alkyl-6-(arylmethyl)uracils. Condensa
