Uses

As photochemical probe in biological systems: P.-S. Song, C.-N. Ou, Ann. N.Y. Acad. Sci. 346, 355 (1980).

Uses

Psoralens are phytoalexins; they are used by plants in a defensive response to attacks by fungi and insects. They have also shown photosensitizing and phototoxic effects in animals and humans and have been used in photochemotherapy for management of vitiligo, psoriasis, and mycosis fungoides. Used as photochemical probe in biological systems.

Uses

Biochem/physiol Actions

Psoralen belongs to the linear type furanocoumarins. It intercalates and induces interstrand cross-links in DNA. On UV exposure psoralen is excited leading to irreversible intercalation with DNA by covalent bond formation. This property of psoralen ultraviolet A light (PUVA) is exploited in treating skin diseases and cutaneous T-cell lymphoma. However, usage psoralen also leads to hepatotoxicity and cytotoxicity by the generation of psoralen photoproducts (POPs). It may be useful in treating osteoporosis
