| titleOfInvention |
Multi-arm polypeptide-poly(ethylene glycol) block copolymers as drug delivery vehicles |
| abstract |
The invention provides a mufti-arm block copolymer for use in delivering a variety of bioactive agents. The copolymer of the invention contains a central core from which extend multiple (3 or more) copolymer arms. Each copolymer arm possesses an inner polypeptide segment and an outer hydrophilic polymer segment. Thus, the overall structure of the copolymer comprises an inner core region that includes the central core and the inner polypeptide segment, while the outer core region is hydrophilic in nature. The mufti-arm copolymer of the invention is particularly useful for delivery of biologically active agents that can be entrapped within the inner core region. |
