Photoproducts formed by near-UV irradiation of thymine in the presence of p-aminobenzoic acid

In addition to the four isomers of cyclobutane thymine dimer, two non-dimer photoproducts of thymine (5,6-dihydrothymine and 5-hydroxymethyluracil) were detected when free thymine base was irradiated at 324 nm in the presence of p-aminobenzoic acid (PABA) at pH 7.0. The yields were found to be enhan...

Description
Summary:In addition to the four isomers of cyclobutane thymine dimer, two non-dimer photoproducts of thymine (5,6-dihydrothymine and 5-hydroxymethyluracil) were detected when free thymine base was irradiated at 324 nm in the presence of p-aminobenzoic acid (PABA) at pH 7.0. The yields were found to be enhanced in the presence of phosphate buffer. Irradiation of thymidine at 324 nm in the presence of PABA lead to the formation of 5,6-dihydrothymidine.
