Inhibition on HIV-1 integrase activity and nitric oxide production of compounds from Ficus glomerata

Nat Prod Commun. 2011 Aug;6(8):1095-8.

Abstract

An ethanol Ficus glomerata wood extract and its purified components were investigated for their HIV-1 integrase (IN) and nitric oxide (NO) inhibitory activities. From bioassay-guided isolation, five compounds: beta-sitosterol-D-glucoside (1), aloe-emodin (2), genistein (3), 1,3,6-trihydroxy-8-methyl-anthraquinone (4) and 3-(1-C-beta-D-glucopyranosyl)-2,6-dihydroxy-5-methoxybenzoic acid (5) were isolated. Among the tested samples, at concentrations of 100 microM; compound 2 showed 31.9% inhibition of HIV-1 IN, followed by 4 (19.5%), whereas other compounds were inactive. With regard to the inhibitory effect on NO production, 3 possessed the highest activity with an IC50 value of 27.5 microM, followed by 4 (IC50 = 34.7 microM) and 2 (IC50 = 41.8 microM), respectively. This is the first time that compounds 2-5 have been isolated from Ficus glomerata.
