BioAssay: AID 335239

Inhibition of human DNA polymerase beta

Four new tetragalloylquinic acids, 3,5-di-O-galloyl-4-O-digalloylquinic acid, 3,4-di-O-galloyl-5-O-digalloylquinic acid, 3-O-digalloyl-4,5-di-O-galloylquinic acid, and 1,3,4,5-tetra-O-galloylquinic acid, were isolated and characterized from a commercial tannic acid as a new class of human immunodeficiency virus (HIV) reverse transcriptase (RT) inhibitor. Compounds 2, 3, and 4 inhibit HIV RT more ..

Title: Anti-AIDS agents, 1. Isolation and characterization of four new tetragalloylquinic acids as a new class of HIV reverse transcriptase inhibitors from tannic acid.

Abstract: Four new tetragalloylquinic acids, 3,5-di-O-galloyl-4-O-digalloylquinic acid, 3,4-di-O-galloyl-5-O-digalloylquinic acid, 3-O-digalloyl-4,5-di-O-galloylquinic acid, and 1,3,4,5-tetra-O-galloylquinic acid, were isolated and characterized from a commercial tannic acid as a new class of human immunodeficiency virus (HIV) reverse transcriptase (RT) inhibitor. Compounds 2, 3, and 4 inhibit HIV RT activity 90, 89, and 84% at 100 microM and 73, 70, and 63% at 30 microM, respectively. Compounds 2-5 also inhibit the HIV growth in cells in the range of 61-70% with low cytotoxicity at 25 microM. The HIV cell growth inhibitory effects of these compounds at 25 microM and 6.25 microM (44-57%) are comparable to their effects against the HIV RT at 30 microM and 10 microM, respectively. The inhibitory effect of 3 against DNA polymerases indicates that the selective antiviral action of 3 is determined by more than its action with HIV RT.
