Discovery of Galangin as a Potential DPP-4 Inhibitor That 2026

The dissertation by Amy Elisabeth Rupert focuses on the development of electroosmotic sampling methods to investigate galanin-degrading ectopeptidase activity in the hippocampus. It presents two sampling designs: a single capillary method and a push-pull electroosmotic sampling technique, both aimed at minimizing tissue damage while allowing for precise fluid collection from brain slice preparations. The study explores the hydrolysis of exogenous galanin following ischemic preconditioning, revealing that pre-conditioned cultures exhibit reduced galanin degradation in specific hippocampal regions. Additionally, the research identifies potential metallopeptidases responsible for galanin hydrolysis and discusses the implications of these findings for understanding neuroprotective mechanisms in the context of ischemic injury.
