Application

Cambinol has been used:
  • as an inhibitor of sirutins (SIRT1 and 2) in hepatocarcinoma cell lines to test its effect on cellular viability and colony formation
  • as a SIRT1 and SIRT2 inhibitor to test its effect on frizzled 7 (FZD7) expression in the breast cancer cells MDA-MB-231 and T-47D cells
  • as a sirutin inhibitor in L929 cells to test its protective effect against tumor necrosis factor (TNF)-induced cell death

Biochem/physiol Actions

Cambinol is a Sirtuin (Human Silent Information Regulator) Type 1/2 Inhibitor. Sirtuins are structurally and mechanistically unrelated to HDACs Class 1 & 2 deacetylases but share many protein targets. HDAC is a large complex enzyme family involved in epigenetic-control of gene expression. Sirt2 has an IC50 equal to 59 μM.
Cambinol, a β-naphthol compound, elicits antitumor activity and impairs the mitogen-activated protein kinase (MAPK) signaling. It has ability to inhibit the secretion of inflammatory cytokines including the tumor necrosis factor and interleukins. Cambinol can be a potential therapeutic agent for treating inflammatory diseases. It also aids protection in events of endotoxic and septic shock.
