Description

Application

Psoralen has been used:

• as a crosslinker for dsRNA for in- situ hybridization studies
• in testing melanin dispersal effects in fish scale melanophores
• to test its stimulatory effects in osteoblast a cell proliferation assay
• as a reference standard in high-performance liquid chromatography (HPLC)

Photochemical reagent for the investigation of nucleic acid structure and function.

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
