CYP4F3 Inhibitors

The chemical inhibitors of CYP4F3 encompass a range of compounds predominantly targeting the cytochrome P450 enzymes, thus influencing CYP4F3's functional activities in fatty acid and leukotriene metabolism. Ketoconazole, Miconazole, Itraconazole, Clotrimazole, Fluconazole, Erythromycin, Voriconazole, Cimetidine, and Troleandomycin inhibit CYP4F3 by directly interacting with its active site or heme group. This interaction leads to a decrease in the enzyme's ability to metabolize its specific substrates, particularly various fatty acids and eicosanoids. These inhibitors bind to the heme iron of CYP4F3, a critical component for its enzymatic function, thus effectively reducing its catalytic activity in lipid metabolism. On the other hand, compounds like Montelukast and Zileuton work indirectly by modulating the levels of leukotrienes, which are substrates for CYP4F3. By reducing leukotriene synthesis or blocking their receptors, these compounds indirectly decrease the substrate availability for CYP4F3, thereby reducing its metabolic activity.

17-Octadecynoic acid exhibits unique interactions with CYP4F3, primarily through its terminal alkyne group, which can engage in specific hydrogen bonding and steric effects within the enzyme's active site. This structural feature may modulate the enzyme's conformation, influencing substrate binding and catalytic activity. The compound's hydrophobic nature enhances its affinity for lipid environments, potentially altering membrane dynamics and affecting metabolic pathways involving fatty acid oxidation.
