title: Synthesis of novel MKC-442 analogues with potent activities against HIV-1.
abstract: Bis(alken-1-yloxy)methanes 2 were synthesized by reacting 2-cyclohexenol, 3-cyclohexenylmethanol, cinnamyl alcohol and its alpha-methyl analogue with dibromomethane. Condensation of 2 with 5, 6-disubstituted uracil derivatives 1 resulted in the desired MKC-442 analogues 3-6. The most active compounds, N-1 cinnamyloxymethyl- and N-1 2-methyl-3-phenylallyloxymethyl substituted 5-ethyl-6-(3, 5-dimethylbenzyl)uracils (5b and 6b), showed activity against wild-type HIV-1 in the nanomolar range, and against Y181C andY181C+K103N, mutant strains known to be resistant to MKC-442, in the micromolar range.
