MDL-800 protects against inflammatory and metabolic dysfunction: role of SIRT6 in the cross-regulation of NFκB, AMPK, and PPAR signaling in rats.

Metabolic syndrome (MetSyn) is a complex, multifactorial disorder characterized by insulin resistance, dyslipidemia, hepatic steatosis, oxidative stress, and chronic inflammation, contributing substantially to the global burden of cardiometabolic diseases. Despite extensive research, effective pharmacological strategies that address the diverse and interconnected pathophysiological mechanisms of MetSyn are lacking. Sirtuin 6 (SIRT6), a NAD-dependent epigenetic regulator, has emerged as a critical modulator of metabolic and inflammatory homeostasis.
