摘要

Four 4-methyl-3′, 4′-di-O-(−)-camphanoyl-(+)-cis-khellactone (4-methyl DCK) analogs (7a– d) with different alkyl substituents at the 2′-position were synthesized and evaluated for inhibition of HIV-1 replication in H9 lymphocytes. 2′-Methyl-2′-ethyl-4-methyl DCK (7b) was more potent (EC50= 0.22 μM, TI> 175) than the other three compounds (7a, 7c, and 7d), but significantly less potent than 4-methyl DCK (2, EC50= 0.0059 μM, TI> 6600). The ...
