UV light is one of the major causes of DNA damage. In spore DNA, due to an unusual packing of the genetic material, a special spore photoproduct lesion (SP lesion) is formed, which is repaired by the enzyme spore photoproduct lyase (Spl), a radical S-adenosylmethionine (SAM) enzyme. We report here the synthesis and DNA incorporation of a DNA SP lesion analogue lacking the phosphodiester backbone. The oligonucleotides were used for repair studies and they were cocrystallized with a polymerase enzyme as a template to clarify the configuration of the SP lesion and to provide information about the base-pairing properties of the lesion. The structural analysis together with repair studies allowed us to clarify the identity of the preferentially repaired lesion diastereoisomer.

The synthesis of O-silyl- and O-acyl-protected furanose glycals from free thymidine was investigated. The method of glycal formation reported by Pedersen et al. was successfully expanded to include 5-ester (toluoyl) protected glycals as well as various combinations of 5'-ester and 3- and 5- tert-butyldimethylsilyl and tert-butyldiphenylsilyl protection. Gram quantities of furanoid glycals can be prepared in a few days in two-four steps in overall yields ranging from 17 to 80%.
