NVP-231

Cas：362003-83-6

Product Information：

NVP-231 is a potent, specific, and reversible CerK inhibitor that competitively inhibits binding of ceramide to CerK. NVP-231 is active in the low nanomolar range on purified as well as cellular CerK and abrogates phosphorylation of ceramide, resulting in decreased endogenous C1P levels. When combined with another ceramide metabolizing inhibitor, such as tamoxifen, NVP-231 synergistically increased ceramide levels and reduced cell growth. Therefore, NVP-231 represents a novel and promising compound for controlling ceramide metabolism that may provide insight into CerK physiological function.

In Vitro：

NVP-231 (0-500 nM; 24 hours) gradually reduces the cellular CerK activity, as measured by NBD-C1P formation, demonstrating that NVP-231 active in transfected cells. The IC50 for CerK in this cellular system is 59.70 ± 12 nM.

NVP-231 (0-1000 nM; 48 hours) decreases cell viability as a dose-dependent manner. This compound shows IC50 values of 1 μM in MCF-7 cells and 500 nM in NCI-H358 cells.

NVP-231 (1 μM; 24-72 hours) induces caspase-3 and caspase-9 cleavage in both cell lines. However, the highest caspase-3 and caspase-9 cleavage and activation occurred at 24 hours in MCF-7 cells, then decreases again. In NCI-H358 cells, caspase-3 and caspase-9 cleavage occurrs continuously over 72 hours.

NVP-231 (0-500 nM; 24 hours) causes a concentration-dependent up-regulation of cyclin B1 phosphorylation at Ser133 and a reduction of CDK1 phosphorylation at Tyr15. The total CDK1 expression also declined upon CerK inhibition
