Bioassay-guided fractionation of the CH(2)Cl(2) extract of the leaves of Marila pluricostata led to the isolation of 17 naturally occurring 4-phenylcoumarins, three of them, 5-hydroxy-8,8-dimethyl-4-phenyl-9,10-dihydro-8H-pyrano-[2,3-f]chromen-2-one (1),
Coumarins and structurally related compounds have been recently shown to inhibit replication of human immunodeficiency virus (HIV) and thus, exhibit a therapeutic potential. In this study we report that mesuol and isomesuol, two 4-phenyl coumarins, isolated from the tree Marila pluricostata,
We have evaluated the anti-HIV activity of eleven natural 4-phenylcoumarins isolated from Marila pluricostata and three of their derivatives. Antiviral activity was assessed on MT-2 cells infected with viral clones carrying the luciferase gene as reporter. Inhibitions of HIV transcription and Tat
