Specific inhibition of human immunodeficiency virus type 1 reverse transcriptase mediated by soulattrolide, a coumarin isolated from the latex of calophyllum teysmannii.
Soulattrolide (1), a coumarin isolated from Calophyllum teysmannii latex, was found to be a potent inhibitor of HIV-1 reverse transcriptase (RT) with an IC50 of 0.34 microM. Inhibition was remarkably specific, with no appreciable activity being observed toward HIV-2 RT, AMV RT, RNA polymerase, or DNA polymerases alpha or beta.
