Product Information
Molecular Weight: 248.71
Formula: C13H13ClN2O
Purity: ≥98%
CAS#: 49843-98-3
Solubility: DMSO up to 50 mM
Chemical Name: 6-Chloro-2,3,4,9-tetrahydro-1H-carb­azole-1-carboxamide
Storage: Powder: 4oC 1 year. DMSO: 4oC 3 month; -20oC 1 year.

Biological Activity:

EX-527 is a highly potent and selective inhibitor of SIRT1 with an IC50 ~98 nM. It does not inhibit histone deacetylase (HDAC) or other sirtuin deacetylase family members (IC50 ~20-100 µM). EX-527 has been used to investigate the relationship between SIRT1-mediated deacetylation of p53, p53 activity, and cell survival following DNA damage, as well as many other biological processes involving SIRT1. 

 

How to Use:

  • In vitro: EX-527 was used at 1-10 µM in vitro and in cellular assays.
  • In vivo: EX-527 was administered by intracerebroventricular injection to rats at 5-10 µg to increase hypothalamic acetyl-p53 levels by inhibiting hypothalamic SIRT1 activity (formulation: dissolved in DMSO in a total volume of 5 μL).
