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).

Result:Reduced blood glucose levels from weeks 12 to 20 and improved body weight by week 14.
Corrected abnormal lipid profiles by reducing serum TC, TG, and LDL levels at 20 weeks.
Reduced GCL edema, increased cell numbers in the INL and ONL, and improved retinal thickness and morphology.
Reduced vascular leaks, improved retinal vascular permeability, and diminished overall fluorescence intensity.
Significantly reduced pericyte loss and the formation of acellular capillaries.
Reduced ROS levels across all retinal layers.
Alleviated structural abnormalities in retinal ganglion cells and vascular endothelial cells in a dose-dependent manner.
Reduced glial cell activation (IBA1 and GFAP) and preserved ganglion cell numbers (BRN3A) in a dose-dependent manner.
Significantly reduced the elevated levels of iNOS, IL-1β, IL-6, and VEGFA in the retinas.
