Predicted CYP Metabolic Sites

CYP3A4 CYP2D6 CYP2C9
m2,2G m2,2G m2,2G

* CYP Metabolic sites predicted with SMARTCyp. SMARTCyp is a method for prediction of which sites in a molecule that are most liable to metabolism by Cytochrome P450. It has been shown to be applicable to metabolism by the isoforms 1A2, 2A6, 2B6, 2C8, 2C19, 2E1, and 3A4 (CYP3A4), and specific models for the isoform 2C9 (CYP2C9) and isoform 2D6 (CYP2D6). CYP3A4, CYP2D6, and CYP2C9 are the three of the most important enzymes in drug metabolism since they are involved in the metabolism of more than half of the drugs used today. The three top-ranked atoms are highlighted. See: SmartCYP and SmartCYP - background; Patrik Rydberg, David E. Gloriam, Lars Olsen, The SMARTCyp cytochrome P450 metabolism prediction server, Bioinformatics, Volume 26, Issue 23, 1 December 2010, Pages 2988–2989 (link)
