ABSTRACT:
Novel compounds that are potent inhibitors of HIV reverse transcriptase (RT) are described in the invention. Thes novel compounds also inhibit replication of a retrovirus, such as human immunodeficiency virus-1 (HIV-1). The novel compounds of the invention include analogs and derivatives of phenethylthiazolylthiourea (PETT), of dihydroalkoxybenzyloxopyrimidine (DABO), and of 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT).The invention additionally provides a composite HIV reverse-transcriptase (RT) nonnucleoside inhibitor (NNI) binding pocket constructed from a composite of multiple NNI-RT complexes. The composite RT-NNI binding pocket provides a unique and useful tool for designing and identifying novel, potent inhibitors of reverse transcriptase.
