Title: PTP1B inhibitors from the seeds of Iris sanguinea and their insulin mimetic activities via AMPK and ACC phosphorylation.
Authors: Yang JL, Ha TKQ, Lee BW, Kim J, Oh WK.
Abstract: To find PTP1B inhibitors from natural products, two new compounds (1 and 2), along with nine known compounds (3-11), were isolated from a methanol-soluble extract of Iris sanguinea seeds. The structures of compounds 1 and 2 were determined based on extensive spectroscopic data analysis including UV, IR, NMR, and MS. The IC50 value of compound 5 on protein tyrosine phosphatase 1B (PTP1B) inhibitory activity is 7.30±0.88µM with a little activity compared to the IC50 values of the tested positive compound. Compound 5 significantly enhanced glucose uptake and activation of pACC, pAMPK and partially Erk1/2 signaling. These results suggest that compound 5 from Iris sanguinea seeds are utilized as both PTP1B inhibitors and regulators of glucose uptake. These beneficial effects could be applied to treat metabolic diseases such as diabetes and obesity.
