Nicotinamide (Vitamin B3) is an amide derivative of vitamin B3 that can inhibit the activity of SIRT1 (IC50: 50-180 μM) and SIRT2 (IC50: 2 μM). Nicotinamide can also increase the levels of NAD+, ATP, and ROS in cells [3].
Nicotinamide (5mM ,72h) treat senescent fibroblasts cells reduces ROS levels and the appearance of senescence phenotypes in senescent fibroblasts[1]. Nicotinamide (50-200μM) treat HepG2 cells enhanced NAD+ biosynthesis in a dose-dependent manner[4] .
Nicotinamide (0.5/1.0 mg/kg) Treatment Alters Whole-Body Physiology and In Vivo Metabolism without Affecting Maximum Lifespan[2]. Long-Term Nicotinamide（300 mg/kg/day；between 6 and 12 months） Administration Reverses Age-Associated Gene Expression Changes in Peripheral Tissues and Enhances Mitochondrial Respiratory Capacity in Skeletal Muscle[5].
