TRIOXSALEN Usage And Synthesis
Chemical PropertiesWhite to slightly beige crystalline powder
Usesmelanizing agent, antipsoriatic
DefinitionChEBI: 7H-Furo[3,2-g]chromen-7-one in which positions 2, 5, and 9 are substituted by methyl groups. Like other psoralens, trioxsalen causes photosensitization of the skin. It is administered orally in conjunction with UV-A for phot therapy treatment of vitiligo. After photoactivation it creates interstrand cross-links in DNA, inhibiting DNA synthesis and cell division, and can lead to cell injury; recovery from the cell injury may be followed by increased melanisation of the epidermi .
Brand nameTrisoralen (Valeant).
Purification MethodsPurify trioxsalen by recrystallisation from CHCl3. If too impure, it is fractionally crystallised from CHCl3/pet ether (b 30-60o) using Norit and finally crystallised from CHCl3 alone to give colourless prisms, m 234.5-235o. It is a photosensitiser so it should be stored in the dark. [UV: Kaufmann J Org Chem 26 117 1961, Baeme et al. J Chem Soc 2976 1949, Beilstein 19/4 V 472.]
