Enhanced hydrolysis rates for the cleavage of bis(4-nitrophenyl)phosphate (BNPP), a model phosphodiester, may be achieved by using appropriately designed ditopic receptors containing the known phosphate-binding nucleus, sapphyrin, attached covalently to suitably oriented polyhydroxyl subunits. Evidence for the interaction between sapphyrin and BNPP comes(More)
The synthesis, characterization, and biolocalization properties of new, fully water-soluble sapphyrins is reported. These systems, which display light absorbing features that make them of potential interest as photodynamic therapy (PDT) sensitizers, were found to localize selectively in pancreatic carcinoma tissue in a xenographic murine model.
