Biodegradable amphiphilic copolymer containing nucleobase: synthesis, self-assembly in aqueous solutions, and potential use in controlled drug delivery
Biodegradable nucleobase-grafted amphiphilic copolymer, the methoxyl poly (ethylene glycol)-b-poly (L-lactide-co-2-methyl-2 (3-(2, 3-dihydroxylpropylthio) propyloxycarbonyl)- propylene carbonate/1-carboxymethylthymine)(mPEG-bP (LA-co-MPT)), was synthesized. 1H NMR titration and FT-IR spectroscopy indicated that the hydrogen-bonding could be formed between mPEG-bP (LA-co-MPT) and 9-hexadecyladenine (A-C16). The ...
