Popis: A series of novel phenethylthiazolylthiourea (PETT) derivatives targeting the nonnucleoside inhibitor (NNI) binding site of HIV reverse transcriptase (RT) have been designed based on the structure of the NNI binding pocket. The structure-based design and synthesis of these new PETT derivatives were complemented by biological assays of their anti-HIV activity. Modeling studies for rational drug design included the construction of a composite NNI binding pocket from nine RT-NNI crystal structures, the analyses of surface complementarity between NNI and RT, and application of Ki calculations combined with a docking procedure involving the novel PETT derivatives. The use of the composite NNI binding pocket allowed the identification and structure-based design of three promising PETT derivatives with ortho-F (2), ortho-Cl (3), and meta-F (5) substituents on the phenyl ring. These novel PETT derivatives were more active than AZT or trovirdine and showed potent anti-HIV activity with IC50[p24] values of1 nM and selectivity indices of100,000.
