摘要

A comparison of Non-Nucleoside HIV-1 Reverse Transcriptase (HIV1-RT) Inhibitors from four pharmaceutical companies (Nevirapine, Boehringer-Ingelheim; TIBO, Janssen; L-697,661, Merck; and BHAP, Pharmacia & Upjohn) is used as an example of how 3D molecular-field similarity methods can be applied when the structres differ significantly. Matching the 3D Molecular Steric Volumes (MSV) and Molecular Electrostatic Potential (MEP) fields provides the means for comparison of these molecules without the need to identify specific atoms or groups. The general procedure outlined in the preceding contribution "3D MOLECULAR SIMILARITY METHODS: In Search of a Pharmacophore" has been followed in developing an overlay "binding" model. The recent availability of the experimental crystal structures of Nevirapine (3HVT) and TIBO (1HNV) forming a complex with the HIV1-RT allows comparison of their relative orientation into the protein active site with the overlay obtained by molecular similarity matching, and a good agreement between the two overlays is found.
