3D-quantitative Structure-activity Relationship and Docking Studies of the Tachykinin NK3 Receptor

The tachykinin NK(3) receptor (NK(3)R) is a novel drug target for schizophrenia and drug abuse. Since few non-peptide antagonists of this G protein-coupled receptor are available, we have initiated this study to gain a better understanding of the structure-activity relationships of NK(3) antagonist compounds. We developed a 3D comparative molecular similarity index analysis (CoMSIA) model that gave cross-validated PLS values with q² >0.5 which were validated using a test set.
