Prof. Dr. Dirk Kuckling: Breaking Bonds in Polymer Chemistry

The German Chemical Society invites you to the GDCh Colloquium

Prof. Dr. Dirk Kuckling will hold a lecture on: Breaking Bonds in Polymer Chemistry (Organic Chemistry and Macromolecular Chemistry, University of Paderborn)

For an effective pharmacotherapy an optimal accumulation of a drug within an affected part of the body is required. Furthermore, a controlled release of the drug at the target site is desired. This can be realized by “intelligent” Systems utilizing different triggers like light, pH value or redox properties to release the drug in a controlled fashion. Colloidal drug delivery systems based on novel
switchable polymers are investigated allowing an effective drug transport into cells and tissues. On one side, the intracellular pH shift in endolysosomal compartments is used to effectively degrade the polymer and release the drug.
On another side, the increased concentration of reductive glutathione (GSH),which especially can be found in tumour cells, is used for the degradation of redox-sensitive polymers. Additionally, light switchable polymers are investigated, that can release the embedded drug from the drug carrier after a short period of irradiation. The final goal is the development of drug delivery
systems being able to respond to different stimuli.

The colloquium will take place at 17h c.t. in the Dr.-Oetker lecture hall of Institute of Physical Chemistry and Electrochemistry (PCI).
The colloquium will be preceded by a coffee talk with the speaker in the library of the PCI from about 16h c.t. onwards.
