Ceranib-2 (Ceramidase inhibitor)

Product Number: B-0043


Ceramides are bioactive sphingolipids which induce apoptosis in cells. Ceramidases (CDase), which hydrolyze the fatty acid chain, keep ceramide levels in check and have been proposed as a target for small-molecule inhibitors for anti-cancer therapy. Ceranib-2 inhibits cellular CDase activity with an IC50 = 28 uM in SKOV3 cells and does not show significant cytotoxity up to 100uM. Incubations of SKOV3 cells with Ceranib-2 resulted in an increase in all ceramide species and a dose-dependant decrease in sphingosine and S1P. Ceranib-2 suppressed tumor growth in a mouse model with subcutaneous JC cell tumors.
