Dicaffeoylquinic acid inhibitors of human immunodeficiency virus integrase: inhibition of the core catalytic domain of human immunodeficiency virus integrase.

Integration of a cDNA copy of the human immunodeficiency virus (HIV) genome is mediated by an HIV-1-encoded enzyme, integrase (IN), and is required for productive infection of CD4+ lymphocytes. It had been shown that 3,5-dicaffeoylquinic acid and two analogues were potent and selective inhibitors of HIV-1 IN in vitro. To determine whether the inhibition of IN by dicaffeoylquinic acids was limit...

Inhibition of human immunodeficiency virus type 1 reverse transcriptase, RNase H, and integrase activities by hydroxytropolones.

Human immunodeficiency virus type I reverse transcriptase (RT) possesses distinct DNA polymerase and RNase H sites, whereas integrase (IN) uses the same active site to perform 3'-end processing and strand transfer of the proviral DNA. These four enzymatic activities are essential for viral replication and require metal ions. Two Mg2+ ions are present in the RT polymerase site, and one or two Mg...

Inhibition of human immunodeficiency virus type 1 integrase by 3'-azido-3'-deoxythymidylate.

The effects of 3'-azido-3'-deoxythymidine (AZT) and three of its intracellular metabolites, azido- thymidine mono-, di-, and triphosphates, on the human immunodeficiency virus type 1 integrase have been determined. AZT mono-, di-, and triphosphate have an IC50 for integration between 110 and 150 microM, whereas AZT does not inhibit the integrase. The inhibition by AZT monophosphate can be parti...

Inhibition of Productive Human Immunodeficiency Virus - l Infection by Cobalamins

Various cobalamins act as important enzyme cofactors and modulate cellular function. We investigated cobalamins for their abilities to modify productive human immunodeficiency virus-l (HIV-1) infection of hematopoietic cells in vitro. We show that hydroxocobalamin (OH-CM), methylcobalamin (Me-Cbl), and adenosylcobalamin Ado-Cbl (Ado-Cbll inhibit HN-1 infection of normal human blood monocytes an...

Inhibition of human immunodeficiency virus type-1 by cdk inhibitors

Current therapy for human immunodeficiency virus (HIV-1) infection relies primarily on the administration of anti-retroviral nucleoside analogues, either alone or in combination with HIV-protease inhibitors. Although these drugs have a clinical benefit, continuous therapy with the drugs leads to drug-resistant strains of the virus. Recently, significant progress has been made towards the develo...
