• 产品描述： SRT 1720 is a selective activator of SIRT1 (EC1.5: 0.16 μM) and shows less potent activities on SIRT2/SIRT3 (EC1.5s: 37 μM/300 μM).

• 靶点： Sirtuin

• 体内研究： SRT1720 exhibited a pharmacokinetic profile suitable for in vivo evaluation in both mouse (bioavailability = 50%, terminal t1/2 = ~5 h, Area Under the Curve (AUC) = 7,892 ng h/ml/) and rat (bioavailability = 25%, terminal t1/2 = ~8.4 h, AUC = 3,714 ng/h/ml). In DIO mice, fasting blood glucose levels are elevated (120–150 mg dl?1 range) after being placed on a high-fat diet. Administration of SRT1720 reduced fed glucose levels after 1 week of treatment with further reduction after 3 weeks of treatment that continued through 10 weeks of dosing. Glucose excursion during an intraperitoneal glucose tolerance test was also significantly reduced in the SRT1720 group, and comparable to rosiglitazone, a PPARγ activator that has been used to treat type 2 diabetes. SRT1720 attenuated stress-induced premature cellular senescence and protected against emphysema induced by cigarette smoke and elastase in mice. In animal tumour model studies, SRT1720 inhibited MM tumour growth. SRT1720 enhanced the cytotoxic activity of bortezomib or dexamethasone

• 细胞实验： Cell viability was assessed with a colorimetric assay using MTT as described previously. Apoptosis assay was quantified using Annexin V-FITC/Propidium iodide (PI) apoptosis detection kit, as per manufacturer's instructions, followed by analysis on FACS Calibur

• 动物实验： Sirtinol (2 mg/kg) was administered by peritoneal injection, whereas SRT1720 (100 mg/kg) was administered through oral gavage 1 hour prior to CS exposure daily for 3 days. In a separate experiment, SRT1720 (25, 50, and 100 mg/kg) or PHA-408 (50 mg/kg) was dissolved in 0.5% carboxymethylcellulose containing 0.025% Tween 20 and injected via oral gavage into the conscious mice 24 hours prior to elastase administration, which was repeated daily (5 days per week) until 21 days after elastase administration. To study the therapeutic effect on emphysema, SRT1720 (100 mg/kg) was orally administered daily for 2 weeks after the development of elastase-induced emphysema
