|20120149649||SHORT-CHAIN CATIONIC POLYAMINO ACID AND USE THEREOF - The present invention provides a cationic polyamino acid suitable for a carrier that can form a stable complex with a nucleic acid under a physiological condition and release the nucleic acid in cells suitably. The cationic polyamino acid can associate with a nucleic acid and includes a cationic amino acid residue having a cationic group in a side chain and a hydrophobic amino acid residue having a hydrophobic group in a side chain. The cationic polyamino acid includes 1 to 20 units of the cationic amino acid residue and is represented by the following formula (1).||06-14-2012|
|20120093881||DISRUPTIVE POLYMER MICELLE COMPOSITION - A pharmaceutical composition containing a drug encapsulated in a polymer micelle composition containing a first block copolymer having affinity with HDL and a second block copolymer having affinity with a lipoprotein excluding HDL, each block copolymer having a hydrophobic polymer chain segment and a hydrophilic polymer chain segment such that a plurality of block copolymers arrange radially with the hydrophobic segments directed inward and the hydrophilic segments directed outward. In the composition, a detachment of the first block copolymer is induced by HDL adhesion which forms a gap and promotes the release of a drug encapsulated, while the second block copolymer excluding an affinity with HDL controls a release speed of the drug encapsulated.||04-19-2012|
