General description

A cell-permeable 2-hydroxy-1-naphthaldehyde derivative that acts as a specific and direct inhibitor of the sirtuin class of deacetylase activity with no affect on human HDAC1 (IC50 = 48 µM, 131 µM and 58 µM for ySir2, hSIRT1 and hSIRT2, respectively). Reported to inhibit Sir2p transcriptional silencing activity in vivo (IC50 = 25 µM), and NAD-dependent histone deacetylase activity of purified recombinant yeast Sir2p and human SIRT2 in vitro (IC50 = 70 µM and 40 µM, respectively). A 10 mM (1 mg/254 µl) solution of Sirtinol (Cat. No. 566321) in DMSO is also available.
A cell-permeable 2-hydroxy-1-napthaldehyde derivative that acts as a specific and a direct inhibitor of sirtuin class of histone deacetylase (HDAC) activity. Does not affect human HDAC1. Reported to block Sir2p transcriptional silencing activity in vivo (IC50 = 25 µM) and NAD-dependent HDAC activity in purified recombinant yeast Sir2p and human SIRT2 in vitro (IC50 = 68 µM and 38 µM, respectively).

Previous studies have suggested that platycodin D is implicated in bone biology and ameliorates osteoporosis development. Platycodin D repressed the osteoclast activity and enhanced bone mineral density in the mouse model. However, the effects of platycodin D on osteoblast differentiation

P53 homolog p63 was shown to play a role in premature ageing phenotype found in mouse models through regulation of the replicative senescence. We previously showed that the forced DeltaNp63alpha expression decreased the SIRT1 protein levels, and induced the replicative

SIRTainty™ Class III HDAC Assay

"The SIRTainty™ Class III HDAC Assay utilizes a novel patent pending technology for the sensitive detection of all known sirtuin family members. Unlike conventional assays that are dependent upon a single pre-labeled fluorescently tagged substrate, the SIRTainty Class III HDAC Assay employs untagged acetylated peptide substrates. This approach not only enables unparalleled flexibility in your choice of sirtuin isoform and peptide substrate, but also eliminates the potential for artifacts due to the use of artificial substrates containing bulky fluorophores."
