Cambinol is a SIRT1 and SIRT2 inhibitor with IC₅₀ values of 56 μM and 59 μM, respectively. Cambinol is a potent brain penetrant neutral sphingomyelinase (N-SMase) inhibitor (exosome inhibitor)^[1][2].

Cambinol inhibits NAD-dependent deacetylase activity of human SIRT1 and SIRT2. Inhibition of SIRT1 activity with cambinol during genotoxic stress leads to hyperacetylation of key stress response proteins and promotes cell cycle arrest. Treatment of BCL6-expressing Burkitt lymphoma cells with cambinol as a single agent induces apoptosis, which is accompanied by hyperacetylation of BCL6 and p53. Cambinol has only weak inhibitory activity against SIRT5 (42% inhibition at 300 μM) and no activity against SIRT3^[1].

Cambinol is well tolerated in mice (100 mg/kg) and inhibits growth of Burkitt lymphoma xenografts. No significant weight loss occurs in cambinol-treated animals relative to controls. Inhibitors of NAD-dependent deacetylases may constitute novel anticancer agents^[1].

.The reporter construct with or without varying amounts of GAL4-BCL6 expression plasmid are introduced into NCI-H460 cells using calcium phosphate method. A plasmid containing cytomegalovirus (CMV)-driven β-galactosidase reporter (50 ng) is cotransfected to control for transfection efficiency. Sixteen hours after transfection, cells are treated with 100 μM cambinol of DMSO (control) for 24 hours and the luciferase and β-galactosidase activity is measured^[1].

Mice: Cambinolat the dose of 100 mg/kg, or vehicle are administered i.v. through tail vein injection or i.p. daily from day 5 to 19 (five injections per week). The dose of 100 mg/kg cambinol is the highest dose that could be administered as a single i.v. injection due to limited solubility of the drug. Tumor size is measured thrice a week using caliper and the tumor volumes are calculated^[1].
