SRT1720 - CAS 925434-55-5 - Calbiochem

General description

A cell-permeable quinolinecarboxamide compound that is shown to inhibit the mitochondrial SIRT3 in a substrate AceCS2- (Acetyl-CoA synthetase 2) competitive (K_i = 0.56 µM; K_m = 2.44 µM; V_max = 173.35 µM/min), but NAD⁺-uncompetitive (K_i = 0.34 µM; K_m = 280 µM; V_max = 0.86 µM/min), manner, indicative of NAD⁺ binding as a prerequisite for inhibitor binding. Also reported to decrease cellular p53 Lys382 acetylation (Effective conc. = 10 µM in U2OS and MEF cultures) and inhibit p300 HAT activity (IC₅₀ = 9 µM) in vitro, as well as offer therapeutic benefits in several murine and rodent type 2 diabetes models (100 mg/kg/dayl p.o.) in vivo. Whether and how SRT1720 activates SIRT1 activity remains uncertain.
