Diprotin A

Description

Diprotin A is a dipeptide and a known inhibitor of the enzyme dipeptidyl peptidase-4 (DPP-4), which plays a critical role in glucose metabolism and insulin signaling pathways. Its chemical structure consists of two amino acids, proline and alanine, linked by a peptide bond, which is crucial for its inhibitory activity against DPP-4. In various studies, Diprotin A has been shown to effectively reduce glucose levels, as evidenced by its action in Drosophila hemolymph (PMID:38002032 ). It has been compared to other DPP-4 inhibitors, demonstrating lower inhibitory potency relative to newer compounds (PMID:39740071 ) and showing non-competitive inhibition characteristics (PMID:36295839 ). Additionally, Diprotin A is involved in neurotrophic pathways, interacting with substrates such as pituitary adenylate cyclase-activating polypeptide (PACAP) and Neuropeptide Y (NPY), which are known for their neuroprotective properties (PMID:39201570 ). The compound's binding affinity and inhibitory potential have been evaluated against other inhibitors, revealing its significance in the context of diabetes management and neuronal homeostasis (PMID:38463830 ). Overall, Diprotin A serves as a valuable reference in the study of DPP-4 inhibitors and their therapeutic applications.
