| Hazard Information | Back Directory | [Description]
The sirtuins (SIRTs) are a family of NAD+-dependent histone deacetylases involved in gene regulation that is relevant to longevity, cancer, gene regulation, energy homeostasis, and apoptosis. JGB1741 is a small molecule inhibitor of SIRT1 with an IC50 value of 15 μM in a cell-free assay. It shows relatively weak inhibition for SIRT2 and SIRT3 with IC50 values greater than 100 μM. JGB1741 inhibits metastatic breast cancer MDA-MB 231 cell proliferation with an IC50 value of 512 nM in a cell-based assay and dose-dependently increases p53 acetylation and p53-mediated apoptosis in these cells. | [in vitro]
jgb1741 potently inhibited the proliferation of human metastatic breast cancer cells, mda-mb 231. jgb1741 showed antitumor effects on three different cancer cell lines, k562, hepg2 and mda-mb 231 with an ic50 of 1, 10 and 0.5 μm, respectively. jgb1741-induced apoptosis has been associated with increase in cytochrome c release, modulation in bax/bcl2 ratio and cleavage of parp [1]. | [storage]
