Effect of mimetic CDK9 inhibitors on HIV-1-activated transcription.

ABSTRACT: Potent anti-retroviral therapy has transformed HIV-1 infection into a chronic manageable disease; however, drug resistance remains a common problem that limits the effectiveness and clinical benefits of this type of treatment. The discovery of viral reservoirs in the body, in which HIV-1 may persist, has helped to explain why therapeutic eradication of HIV-1 has proved so difficult. In the current study, we utilized a combination of structure-based analysis of cyclin/CDK complexes with our previously published Tat peptide derivatives. We modeled the Tat peptide inhibitors with CDKs and found a particular pocket that showed the most stable binding site (Cavity 1) using in silico analysis. Furthermore, we were able to find peptide mimetics that bound to similar regions using in silico search
