Metalated hybrid polymers as catalytic reagents for phosphate ester hydrolysis and plasmid modification.
Pendant pyrazolylcyclophosphazene containing hybrid cross-linked polymer (CPPL) has been utilized for binding Zn(II). The metalated polymer (CPPL-Zn) has been found to be very effective catalyst for the hydrolysis of a RNA model phosphodiester substrate [2-(hydroxypropyl)-p-nitrophenyl phosphate, hNPP]. In addition, CPPL-Zn also cleaved supercoiled plasmid DNA pBR322 thus providing a novel structural motif of inorganic-organic hybrid polymers as synthetic nucleases.
