Biological Activity

SRT1720 is a selective small molecule activator of SIRT1 that is 1,000-fold more potent than resveratrol (EC1.5 = 0.16 versus 46.2 µM, respectively). SIRT1 belongs to the silent information regulator 2 (Sir2) protein family of enzymes and functions as a NAD(+) -dependent class III histone deacetylase. Treatment of MM cells with SRT1720 inhibited growth and induced apoptosis in MM cells resistant to conventional and bortezomib therapies without significantly affecting the viability of normal cells. Mechanistic studies showed that anti-MM activity of SRT1720 is associated with: (i) activation of caspase-8, caspase-9, caspase-3, poly(ADP) ribose polymerase; (ii) increase in reactive oxygen species; (iii) induction of phosphorylated ataxia telangiectasia mutated/checkpoint kinase 2 signalling; (iv) decrease in vascular endothelial growth factor-induced migration of MM cells and associated angiogenesis; and (v) inhibition of nuclear factor-κB. Blockade of ATM attenuated SRT1720-induced MM cell death. Finally, SRT1720 enhanced the cytotoxic activity of bortezomib or dexamethasone.

Protocol
Cell Experiment
Cell lines 4T1 cells
Preparation method Cell viability assay.
One day before treatment, 1.5x104 cells per well were seeded in a 96-well plate and allowed to attach overnight. The cells were then treated with varying concentrations of SRT1720 for 24 h. The viable cell number was determined with an MTS assay kit (Promega, Madison, WI, USA).
Concentrations 0~5 μM
Incubation time 24 h
Animal Experiment
Animal models 4T1 cells tumor-bearing mice model
Formulation water
Dosages 100 mg/kg 5 times per week
Administration orally
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
