A new version of a benzophenone antenna-sensitised photolabile derivative Of L-glutamate, which has a dicarboxylic acid substituent on the benzophenone to promote water solubility, has been synthesised. It does not show problems of precipitation in the presence of calcium ions that were encountered with related compounds in which one or two phosphate groups were present as water-solubilising substituents but retains the enhanced photolytic efficiency that results from the benzophenone antenna. Photolysis of the compound proceeds with stoichiometric release of L-glutamate and pharmacological evaluations have shown that the compound itself has no evidence of agonist or antagonist activity in its unphotolysed form.
