SYNTHETIC APPROACHES TO 4,8-DIMETHYL-4'- (N-PYRIDINIUMMETHYL)- 4',5'-DIHYDROPSORALENS AND THEIR ACTIVITY AGAINST PAM 212 KERATINOCYTES
{{output}}
Synthetic approaches to novel 4,8-dimethyl-4'-halomethyl-4',5'-dihydropsoralens as synthetic precursors to 4,8-dimethyl-4'-(N-pyridiniummethyl)-4',5'-dihydropsoralens are described. The compounds are potential therapeutic agents for improved psoralen ultraviol... ...
