Trioxsalen

Approved Small Molecule

Trioxsalen

Trioxsalen (trimethylpsoralen, trioxysalen or trisoralen) is a furanocoumarin and a psoralen derivative obtained from several plants, mainly Psoralea corylifolia. Like other psoralens it causes photosensitization of the skin. It is administered either topically or orally in conjunction with UV-A (the least damaging form of ultraviolet light) for phototherapy treatment of vitiligo and hand eczema. The photoactivated form produces interstrand linkages in DNA resulting in cell apoptosis. In research it can be conjugated to dyes for confocal microscopy and used to visualize sites of DNA damage.[3] The compound is has been explored for development of antisense oligonucleotides that can be cross-linked specifically to a mutant mRNA sequence without affecting normal transcripts differing at even a single base pair.

External IDsNSC-71047
IndicationTrioxsalen is a pigmenting photosensitizing agent used in conjunction with ultraviolet light in the treatment of vitiligo.
PharmacodynamicsTrioxsalen ispharmacologically inactive but when exposed to ultraviolet radiation or sunlight it is converted to its active metabolite to produce a beneficial reaction affecting the diseased tissue.
Food interactionsavoid eating limes, figs, parsley, parsnips, mustard, carrots, and celery while you are being treated with trioxsalen
