1 In silico exploration of phenytoin binding site in two catalytic states of human P-glycoprotein models. Phenytoin ATP binding cassette subfamily B member 1 Homo sapiens
2 Earlier studies have identified drug efflux due to the over-expression of P-gp as one of the causes for the resistance of phenytoin, an anti-epileptic drug (AED). Phenytoin ATP binding cassette subfamily B member 1 Homo sapiens
3 While no clear evidence exists on the specific characteristics of phenytoin association with the human P-gp, this study employed structure-based computational approaches to identify its binding site and the underlying interactions. Phenytoin ATP binding cassette subfamily B member 1 Homo sapiens
4 Further, an in silico proof-of-concept for phenytoin interactions and its decreased binding affinity with the closed-state of human P-gp model was provided in comparison with other AEDs. Phenytoin ATP binding cassette subfamily B member 1 Homo sapiens
5 This is the first report to provide insights into the phenytoin binding site and possibly better explain its efflux by P-gp. Phenytoin ATP binding cassette subfamily B member 1 Homo sapiens
