Abstract Syntheses and characterization of polymer conjugates of 9-[2-(phosphonomethoxy) ethyl](PME) derivatives of adenine (PMEA), 2, 6-diaminopurine (PMEDAP) and guanine (PMEG) are described. The phosphonate group of these acyclic nucleotide analogues was activated by reaction with triphenylphosphine and di (2-pyridyl) disulfide (TPP-PDS). The activated phosphonate reacted with a random copolymer containing N-(2-hydroxypropyl) ...
