Biochem./physiol. Wirkung

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
