Description

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.

Pharmacology

Indication

Trioxsalen is a pigmenting photosensitizing agent used in conjunction with ultraviolet light in the treatment of vitiligo.

Pharmacodynamics

Trioxsalen 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.

Mechanism of action

After photoactivation it creates interstrand cross-links in DNA, which can cause programmed cell death.

Cross-linking/alkylation
DNA is the molecule of heredity, as it is responsible for the genetic propagation of most inherited traits. It is a polynucleic acid that carries genetic information on cell growth, division, and function. DNA consists of two long strands of nucleotides twisted into a double helix and held together by hydrogen bonds. The sequence of nucleotides determines hereditary characteristics. Each strand serves as the template for subsequent DNA replication and as a template for mRNA production, leading to protein synthesis via ribosomes.
