Publication number: 20140301967Abstract: Antimicrobial cationic polymers having one or two cationic polycarbonate chains were prepared by organocatalyzed ring opening polymerization. One antimicrobial cationic polymer has a polymer chain consisting essentially of cationic carbonate repeat units linked to one or two end groups. The end groups can comprise a covalently bound form of biologically active compound such as cholesterol. Other antimicrobial cationic polymers have a random copolycarbonate chain comprising a minor mole fraction of hydrophobic repeat units bearing a covalently bound form of a vitamin E and/or vitamin D2. The cationic polymers exhibit high activity and selectivity against Gram-negative and Gram-positive microbes and fungi.Type: ApplicationFiled: April 9, 2013Publication date: October 9, 2014Applicants: AGENCY FOR SCIENCE, TECHNOLOGY AND RESEARCH, INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Willy Chin, Daniel J.

Publication number: 20140303329Abstract: This invention provides Chelating Complex Micelles as a drug carrier. The Chelating Complex Micelles can load drugs without changing their structure, and therefore extend the half-life of drugs in the human body. The chelating complex micelles contain a metal ion core, at least one polymer, and at least one drug molecule. The metal ion is considered as a Lewis acid while polymer chain and drug molecules are referred to as Lewis bases. The drug molecule is linked to the polymer via forming coordinate bonds with metal ion, and then self-assembled to form chelating complex micelles as a drug carrier.Type: ApplicationFiled: June 17, 2014Publication date: October 9, 2014Inventors: Chau-Hui Wang, Chia-Hung Chen, Johnson Lin, Jing-Yi Chen, Wei-Chuan Liao
