Obtusin
Based on 1 Customer Validation
Obtusin is an orally active human monoamine oxidase A (hMAO-A) inhibitor discovered from the seeds of Cassia obtusifolia, with a Ki value of 6.15 μM. Obtusin inhibits high glucose-induced activation of the MAPKs/NF-κB/VEGF pathway and downregulates the expression of Poldip2, Nox4, VCAM-1, and HIF-1α, thereby alleviating oxidative stress, endothelial activation, and angiogenesis-related functions. Obtusin ameliorates diabetic retinopathy in vivo. Obtusin is used in research related to diabetes and neurodegenerative diseases (anxiety and depression).
