This study provides a comprehensive computational exploration of the inhibitory activity and metabolic pathways 8-methoxypsoralen (8-MP), furocoumarin derivative used for treating various skin disorders, on cytochrome P450 (P450). Employing quantum chemical DFT calculations, molecular docking, dynamics (MD) simulations analyses, biotransformation mechanisms active site binding profile 8-MP in CYP1B1 were investigated. Three plausible inactivation minutely scrutinized. Further analysis explored formation reactive metabolites subsequent processes, including covalent adduct through nucleophilic addition to epoxide, epoxide hydrolysis, non-CYP-catalyzed ring opening. Special attention was paid catalytic effect residue Phe268 mechanism-based (MBI) by 8-MP. Energetic profiles facilitating conditions revealed slight preference C4′=C5′ epoxidation pathway, while recognizing potential kinetic competition with 8-OMe demethylation pathway due comparable energy demands. The adducts via addition, particularly phenylalanine, generation potentially harmful autocatalyzed cleavage are likely contribute significantly metabolism Our findings highlight key role retaining within CYP1B1, thereby initial oxygen transition states. research offers crucial molecular-level insights that may guide early stages drug discovery risk assessment related use

Vanillin, a key flavor compound found in vanilla beans, is widely used the food and pharmaceutical industries for its aromatic properties potential therapeutic benefits. This study presents comprehensive quantum chemical analysis to elucidate interaction mechanisms of vanillin with CYP450 enzymes, focus on mechanism-based inactivation. Three inactivation pathways were evaluated: aldehyde deformylation, methoxy dealkylation, acetal formation. Aldehyde deformylation was identified as most energy-efficient, involving removal group from leading formation benzyne intermediates that could react iron porphyrin moiety CYP450, potentially resulting enzyme Further investigation into interactions CYP2E1 CYP1A2 conducted using molecular docking dynamics (MD) simulation. The analyses supported findings DFT studies, wherein revealed high binding affinities studied isozymes. Moreover, occupied main site both isozymes, evidenced by inclusion heme their mechanisms. Employing 100 ns simulation, we scrutinized between two isozymes CYP450. assessment various MD parameters along energies exhibited stable trajectories substantial energy stabilization during These insights can guide future research ensure safe application vanillin, especially scenarios where it may interact enzymes.
