Biological Activity

KY-226 is a protein tyrosine phosphatase 1B (PTP1B) inhibitor with IC50 of 0.25 μM, which protects neurons from cerebral ischemic injury. KY-226 exerts anti-diabetic and anti-obesity effects by enhancing insulin and leptin signaling, respectively. KY-226 (0.3-10 μM) increases the phosphorylated insulin receptor (pIR) produced by insulin in human hepatoma-derived cells. 

In vivo, KY-226 (10-30 mg/kg/day; oral; for 4 weeks) treatment in male db/db mice significantly reduces plasma glucose and triglyceride levels as well as hemoglobin A1c values without increasing body weight gain.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
