Inauhzin（Cat No.:I003092） is a compound that acts as a cell-permeable inhibitor of SIRT1, an enzyme involved in cellular processes and aging. It exhibits an inhibitory concentration (IC50) range of 0.7-2 μM against SIRT1. By inhibiting the deacetylation activity of SIRT1, Inauhzin can reactivate p53, a tumor suppressor protein that plays a critical role in regulating cell growth and preventing cancer development. This reactivation of p53 can have implications for cancer therapy and potential therapeutic applications in diseases associated with SIRT1 dysregulation.
