SRT 1720 is a selective activator of human SIRT1 with an EC1.5 of 0.16 μM, and shows less potent activities agaiinst SIRT2 and SIRT3 with EC1.5s of 37 μM and > 300 μM, respectively. SIRT1|0.16 μM (EC1.5)|SIRT2|37 μM (EC1.5)
SRT 1720 effectively decreases the acetylation of p53 in cells even in the absence of SIRT1, and this is attributed to inhibition of histone acetyltransferase p300[2].
SRT 1720 (10, 30, 100 mg/kg, p.o.) significantly reduces the hyperinsulinaemia after 4 weeks, partially normalizing elevated insulin levels similar to rosiglitazone treatment. SRT 1720 treatment significantly reduces fasting blood glucose to near normal levels in Lepob/ob mice[1]. SRT 1720 has ability to protect against the negative effects of diet-induced obesity in mice, and has a connection to metabolic adaptation in fatty acid and oxidative metabolism through downstream targets of SIRT1 such as PGC1α and FOXO1[2]. SRT 1720 (50-100 mg/kg, p.o.), during emphysema development attenuates elastase-induced airspace enlargement and lung function impairment as well as reduces arterial oxygen saturation in WT mice[3].
