Biological activities

Gemfibrozil is a nonselective inhibitor of several P450 isoforms and uridine diphosphate glucuronosyltransferases. In vitro, gemfibrozil strongly inhibits CYP2C9, CYP2C19 and CYP1A2 with Ki of 5.8, 24 and 82 µM, respectively. Additionally, gemfibrozil inhibits paclitaxel 6a-hydroxylation with an IC50 of 91 µM. Gemfibrozil increases the risk of myopathy associated with simvastatin and lovastatin.[1] Gemfibrozil is an inhibitor of CYP- and UGT-mediated metabolism of cerivastatin (CER). Gemfibrozil significantly inhibits the OATP2-mediated uptake of CER and CYP2C8-mediated metabolism of CER with IC50 of 72 and 28 µM, respectively. Gemfibrozil inhibits CYP2C8-mediated M1 and M23 formation with IC50 of 36.8 and 29.7 µM, respectively. [2] Gemfibrozil lowers plasma PAI-118 in survivors of acute myocardial infarction. Gemfibrozil reduces basal PAI-1 synthesis by 20% and attenuates the TGF-β-induced 4.5-fold increase over 6 hours by 49%.[3]

Protocols

Gemfibrozil is dissolved in culture medium containing 0.1% DMF in final concentrations. [3]
