excellent quality and reasonable price and absolutely worthy.

Tenovin-6 inhibits the growth of S. cerevisiae cultures with an IC50 of 30 μM and is more toxic to yeast than the less water-soluble tenovin-1. Tenovin-6 decreases purified human SirT1 peptide deacetylase activity in vitro with an IC50 of 21 μM and human SirT2 activity with an IC50 of 10 μM. Inhibition of SirT3 by tenovin-6 in this assay was significantly lower with an IC50 of 67 μM.Tenovin-6 does not inhibit enzymatic assays in general as the activity of a panel of 51 purified kinases was not significantly affected [1]. KIAA1967 expression is differentially downregulated in PDAC and impacts on the sensitivity of PDAC cells to the Sirt1/2 inhibitor Tenovin-6 . In chronic lymphocytic leukemia (CLL) cells, Tnv-6 causes non-genotoxic cytotoxicity, without adversely affecting human clonogenic hematopoietic progenitors in vitro, or murine hematopoiesis. Mechanistically, exposure of CLL cells to Tnv-6 did not induce cellular apoptosis or p53-pathway activity .
