Abstract
Multiple crystal structures of CYP3A4 bound with various substrates or inhibitors have been used as templates for docking of new chemical entities to predict sites of metabolism and molecular interactions for drug design. Herein, modeling studies with dirlotapide, a CYP3A4 substrate, indicated that a substantial conformational change of CYP3A4 was necessary to accommodate it within the active site cavity, which is in good agreement with a new published CYP3A4 ritonavir co-crystal structure. Thus, the importance of considering the substrate-induced conformational change in CYP3A4, thermochemical properties of reaction centers, and essential in vitro experimental data support were analyzed for the refinement of computational models.
