We demonstrate that a photo-labeled derivative of the non-nucleoside reverse transcriptase inhibitor (NNRTI) dapivirine termed DAPY, when used together with exposure to ultraviolet light, was able to completely and irreversibly inactivate both HIV-1 RT activity as well as infectiousness in each of a T cell line and peripheral blood mononuclear cells. Control experiments using various concentrations...
We describe a new method for the development of a preventive inactivated-HIV vaccine, based on photo-inactivation of HIV reverse transcriptase (RT), which preserves both the conformational and functional integrity of viral surface proteins. The RT of HIV-1 was selectively targeted for inactivation using a photo-labeled compound with specific affinity for HIV-1 RT. The photo-labeled virions were then...
