摘要： This present invention relates to a drug carrier comprising a polymer of γ-glutamyl transpeptidase catalyzing hydrolysis-induced charge reversal, and a method for preparing the same. It can have a long circulation time in the blood, and can realize a charge reversal from negatively charged or the neutral to positively charged around the tumor blood vessel region, so that the positively charged polymer effectively penetrates deep into the tumor tissue, fast entering into the tumor cells, and greatly improves the therapeutic effect of the drug on the tumor. This overcomes the problems of slow diffusion of traditional polymer drug carriers in tumors and weak interaction with tumor cells, and has great significance in the field of anticancer treatment in the medical field.

摘要： Disclosed are chelating co-polymer compositions that are soluble in aqueous media and chelate essential metals, methods of preparation and uses thereof. The chelating compositions are comprised of two or more different monomers, at least one of which possesses metal binding or metal chelating activity. The chelating compositions are synthesized by reversible addition-fragmentation transfer (RAFT) polymerization with the aid of a suitable RAFT-mediating agent. Also described are chelating compositions that comprise hydroxypyridinone chelating groups. The ability of the chelating compositions to bind metals affects the activity of a living cells and organisms, which require the metals for cellular functions.
