Synthesis and Characterization of New DNA-Mimic Brush Polymers Bearing Adenine Moieties |
초록 |
In this study, we describe new well-defined DNA-mimicking brush polyoxyethylenes bearing adenine moieties at the bristle ends : poly[oxy(11-(3-(9-adeninyl-propionato)-undecanyl-1-thiomethyl)ethylene](PECH-AP) and poly[oxy(11-(5-(9-adenylethyloxy)-4-oxopentanoato)undecanyl-1-thiomethyl)ethylene](PECH-AS). these polymers were found to be thermally stable up to 220 °C and could be applied easily by conventional coating processes. Interestingly, both brush polymers formed molecular multi-bilayer structures. PECH-AS surprisingly exhibited higher hydrophilicity and better water sorption properties than PECH-AP. The adenine-rich surfaces demonstrated facilitated HEp-2 cell adhesion, suppressed bacterial adherence, selective protein adsorption, and exhibited good biocompatibility in mice. However, the high hydrophilicity and good water sorption characteristics of the PECH-AS film suggest that this brush polymer is better suited to applications requiring good biocompatibility. |
