NAMPT activator-10 (Compound B11) is an orally active NAMPT activator with a target Kd value of 0.64 μM. NAMPT activator-10 activates the rate-limiting enzyme in NAD+ biosynthesis and promotes intracellular NAD+ synthesis. NAMPT activator-10 reduces lactate accumulation, enhances glycogen storage in the liver and muscle, increases tissue ATP production, improves exercise endurance and muscle strength, and exerts a protective effect against fatigue-induced muscle damage in mouse fatigue models. NAMPT activator-10 can be used in studies related to muscle fatigue.

Description

NAMPT activator-10 (Compound B11) is an orally active NAMPT activator with a target Kd value of 0.64 μM. NAMPT activator-10 activates the rate-limiting enzyme in NAD+ biosynthesis and promotes intracellular NAD+ synthesis. NAMPT activator-10 reduces lactate accumulation, enhances glycogen storage in the liver and muscle, increases tissue ATP production, improves exercise endurance and muscle strength, and exerts a protective effect against fatigue-induced muscle damage in mouse fatigue models. NAMPT activator-10 can be used in studies related to muscle fatigue[1].

In Vitro

NAMPT activator-10 (0-8.0 μM) potently activates purified NAMPT enzyme in a concentration-dependent manner, with a maximum activation effect reaching 206%[1].
NAMPT activator-10 (0-5.00 μM) binds to purified NAMPT enzyme with high affinity (Kd = 0.64 μM)[1].
NAMPT activator-10 (0-4.0 μM; 4 h) increases intracellular NAD+ levels in THLE-2 hepatocytes in a concentration-dependent manner within 4 hours[1].
NAMPT activator-10 (72 h) exhibits low cytotoxicity after 72 h of treatment in THLE-2 hepatocytes (IC50 = 316 μM) and C2C12 mouse myotube cells (IC50 = 236 μM)[1].
NAMPT activator-10 (1.25-10.0 μM) increases the phosphorylation level of AMPK in C2C12 mouse myotubes in a concentration-dependent manner[1].

In Vivo

Compound B11 (20 mg/kg; i.p.; daily; 3 days) alleviates muscle fatigue by reducing lactate buildup and increasing energy reserves in liver and muscle tissue[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
