A 3D-QSAR combined study of the biological action and biological activity of 5-HT1A agonists has been performed. Conformational analysis and comparative analysis of active and inactive conformers of 5-HT1A agonists has been fulfilled. The orientation and alignment of the 5-HT1A agonists has been performed using a novel algorithm ConGO (Continual Grid Overlap). The algorithm uses quantum-derived wave functions for orientation and alignment of molecules in complementary self-considering field. Also the molecular similarity of active drugs has been evaluated in terms of electron density comparison. On the base of the elucidation the pharmacophoric and anti-pharmacophoric parts of molecules have been defined. The receptor – ligand models are created using BiS algorithm and characteristics of interactions are determined.
