Abstract
The use of polymers in different fields of modern medicine has generated significant advances in tissue engineering, diagnostic and therapeutic strategies. Polymers have been used to control the rate of drug release, prevent toxicity, protect drugs from degradation before delivery, target drugs to the site of action, improve absorption, bioavailability and therapeutic efficacy. Although synthetic polymers allow producing tailor-made materials, however natural polymers exhibit the advantages of excellent biodegradability, biocompatibility, cost-effectiveness and environmental friendliness. This review presents the current status of research and clinical applications of natural polymers as drug delivery systems for different administration routes.
Keywords: Natural polymers, proteins, polysaccharides, drug delivery, mucosal delivery, enteral delivery, central nervous system delivery.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
