제목 Folic acid Tethered Temperature Responsive Lipopolymer Hybrid Materials for Doxorubicin Delivery
초록 A series of temperature responsive lipopolymer hybrid materials, DPPE-p(NIPAM)n, PE-p(NIPAM)n, Alkyne PE-p(NIPAM)n (n=60,40,25) have been synthesized by the combination of radical polymerization and click chemistry. The lipids were modified to azide terminated lipids and alkyne terminated p(NIPAM) were synthesized by employing reversible addition-fragmentation chain transfer polymerization (RAFT) for the azide-alkyne click reaction. For the active targeting of cancer cells folic acid is tethered into the DPPE-p(NIPAM)n by employing thiol-ene click reaction. The structural characterization was carried out by various spectroscopic techniques. The temperature induced self-assembly resulted in micelles (200 nm) capable of controlled release of hydrophobic drug doxorubicin.
