SBI-797812 is an orally active nicotinamide phosphoribosyltransferase (NAMPT) activator. SBI-797812 shifts NAMPT to NMN formation, increases NAMPT affinity for ATP, stabilizes phosphorylated NAMPT, promotes consumption of the pyrophosphate by-product, and blunts feedback inhibition by NAD+. SBI-797812 increases intracellular nicotinamide mononucleotide (NMN) and elevates liver NAD+ in mice[1][2]. | [Biochem/physiol Actions]
SBI-797812 is a cell penetrant and potent activator of nicotinamide phosphoribosyltransferase (NAMPT) that increases intracellular levels of NMN and NAD+ in cells. SBI-797812 blocks binding of inhibitors to NAMPT and shifts the reaction equilibrium towards NMN formation. It elevates levels of NAD+ in mice liver. | [in vivo]
SBI-797812 (10 mg/kg; i.p. or o.p.; single dose) shows high plasma exposure by intraperitoneal injection, with Cmax value of 3297?ng/mL, 8.2?μM[1].
?
SBI-797812 (20 mg/kg; i.p.; single dose; measured 2?h post-dose) significant increases NAD+ in mouse liver[1].
| Animal Model: | Male C57BL/6?J mice (8-week-old)[1] | | Dosage: | 20 mg/kg | | Administration: | Intraperitoneal injection; administrated 1 h after fasting; added Buthanasia-D (165?mg/kg; i.p.) 4 h after fasting | | Result: | Showed 0.311, 0.144, 0.078, and 0.078?μg/mg dry powder about NAD+ in liver, heart, gastrocnemius and quadriceps, respectively by LC-MS/MS measurement.
