title: Anti-AIDS agents 66: syntheses and anti-HIV activity of phenolic and aza 3',4'-di-O-(-)-camphanoyl-(+)-cis-khellactone (DCK) derivatives.
abstract: New phenolic and aza 3',4'-di-O-(-)-camphanoyl-(+)-cis-khellactone (DCK) analogs were synthesized and assayed for inhibition of HIV-1 IIIB replication in H9 lymphocytes. Compound 16, 4-methyl-1'-aza-DCK (4-methyl-aza-DCK), was less lipophilic than 4-methyl-DCK, and retained sub-micromolar anti-HIV activity with EC(50) and TI values of 0.77 microM and >42, respectively. Moreover, it showed moderately improved metabolic stability. Introduction of phenolic hydroxyl groups to 4-methyl-DCK decreased lipophilicity significantly, but did not improve metabolic stability and also decreased activity.
