Molecular Insight into Affinities of Drugs and Their Metabolites to Lipid Bilayers

Popis výsledku v původním jazyce

The penetration properties of drug-like molecules on human cell membranes are crucial for understanding the metabolism of xenobiotics and overall drug distribution in the human body. Here, we analyze partitioning of substrates of cytochrome P450s (caffeine, chlorzoxazone, coumarin, ibuprofen, and debrisoquine) and their metabolites (paraxanthine, 6-hydroxychlorzoxazone, 7-hydroxycoumarin, 3-hydroxyibuprofen, and 4-hydroxydebrisoquine) on two model membranes: dioleoylphosphatidylcholine (DOPC) and palmitoyloleoyl-phophatidylglycerol (POPG). We calculated the free energy profiles of these molecules and the distribution coefficients on the model membranes. The drugs were usually located deeper in the membrane than the corresponding metabolites and also had a higher affinity to the membranes. Moreover, the behavior of the molecules on the membranes differed, as they seemed to have a higher affinity to the DOPC membrane than to POPG, implying they have different modes of action in human (mo
