Bioactivity
Description
Selisistat S-enantiomer (EX-527 S-enantiomer) is an effective and specific SIRT1 inhibitor (IC50 = 98 nM) and shows >200-fold selectivity against SIRT2/3.
Targets&IC50
SIRT1:98 nM
In vitro
Treatment with Selisistat S-enantiomer dramatically increased acetylation at lysine 382 of p53 after different types of DNA damage in primary human mammary epithelial cells and several cell lines. Inhibition of SIRT1 catalytic activity by Selisistat S-enantiomer had no effect on cell growth, viability, or p53-controlled gene expression in cells treated with etoposide [1]. When the function of SIRT1 is inhibited by Selisistat S-enantiomer or its expression is suppressed by RNAi, the upregulated level and release of IL-1β and TNF-α by high glucose are further increased [2]. When HCT116 cells were cultured in 0.1% serum, addition of Selisistat S-enantiomer caused a 90% increase in cell number after 7 days. In the presence of 10% serum, Selisistat S-enantiomer did not change cell number in long term culture [3].
In vivo
The central pretreatment with Selisistat S-enantiomer blunted the ghrelin-induced food intake in rats. Mice lacking p53, a target of SIRT1 action, failed to respond to ghrelin in feeding behavior. Ghrelin failed to phosphorylate hypothalamic AMPK when rats were pretreated with Selisistat S-enantiomer, as it did in p53 KO mice [4]. Selisistat S-enantiomer abolished RSV-induced attenuation of microvascular inflammation in ob/ob septic mice [5].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
