Cyp induction studies
WebXenoTech’s CYP Inhibition and Enzyme Induction studies are designed to capture R 1, R 2 and R 3 data which can be used in the FDA/EMA basic model (shown below). These values can be used to study the combined effects of CYP inhibition and CYP induction, also known as the net effects model, described in the 2012 FDA guidance. WebThe models most often used in vitroinclude: 1) metabolizing recombinant enzymes (e.g., CYP and UDP-glucuronosyltransferases); 2) subcellular fractions (e.g., microsomes, cytosols or S-9 fractions); and 3) cellular organelles (e.g., hepatocytes and liver slices). 1.
