Abstract

Novel compounds 1a-u, which can be considered as hybrid analogues of MKC-442 and pyridinon, have been synthesized and evaluated as inhibitors of HIV-1 reverse transcriptase (HIV-1 RT). Starting from 6-methyluracil 2, 1-alkylated-5-bromomethyl-6-methyluracils 8 was prepared in four steps by hydroxymethylation, etherification, N-1 alkylation, and bromination. Finally, compounds 1a-u were achieved in the displacement of 5-bromomethyl group by nucleophiles with amino compounds. Some of compounds 1a-u showed potent inhibitory activity against HIV-1 RT. The most active compounds showed activity in the low micromolecular range with IC(50) values (IC(50) 0.82-5.09 microM) comparable to that of nevirapine (IC(50) 10.60 microM). The biological testing results are in accordance with the docking.
