Virtual screening application of a model of full-length HIV-1 integrase complexed with viral DNA

To address the absence of experimental data on the full-length structure of HTV-1 integrase and the way it binds to viral and human DNA, we had previously [Karki, R. G.; Tang, Y.; Burke, T. R., Jr.; Nicklaus, M. C. J. Comput. Aided Mol. Des. 2004, 18, 739] constructed models of full-length HIV-1 integrase complexed with models of viral and human DNA. Here we describe the discovery of novel HIV-1 integrase strand transfer inhibitors based on one of these models. Virtual screening methods including docking and filtering by predicted ADME/Tox properties yielded several mu M level inhibitors of the strand transfer reaction catalyzed by wild-type HIV-1 integrase.
