Methoxsalen (8-Methoxypsoralen) is a potent tricyclic furocoumarin suicide inhibitor of CYP (cytochrome P-450). As a member of the foranocoumarins, 8-Methoxypsoralen has shown more potency than 5-MOP, 5-OH-P, DH-8-MOP and psoralen in the inhibiton of CYP2B1 (cytochrome P-450 2B1). Methoxsalen may act to completely inhibit the metabolism of nicotine (sc-212379) in vitro. The compound has been observed to inhibit the metabolism of theophylline (sc-202835), caffeine (sc-202514), hexobarbital and phenytoin (sc-210385).
