Identification of new scavengers for hydroxyl radicals and superoxide dismutase by utilising ultraviolet A photoreaction of 8-methoxypsoralen and a variety of mutants of Escherichia coli: implications on certain diseases of DNA repair deficiency.

Abstract excerpt

8-Methoxypsoralen+UVA (ultraviolet light of 320-400 nm) known as PUVA has been in use for a number of years for the treatment of psoriasis and vitiligo. The treatment possibly works on the basis of UVA photoactivated 8-methoxypsoralen binding to DNA forming both single strand and double strand type damage. We have used Escherichia coli as model system in studying PUVA induced DNA damage and repair. It has been...
