| 生物活性 | K145 is a selective, substrate-competitive and orally activeSphK2inhibitor with anIC50of 4.3 μM and aKiof 6.4 μM. K145 is inactive againstSphK1and other protein kinases. K145 induces cellapoptosisand has potently antitumor activity[1]. |
| IC50& Target | IC50: 4.3 μM (SphK2)[1]
Ki: 6.4 μM (SphK2)[1] |
体外研究
(In Vitro) | K145 (0-10 μM; 24-72 hours; U937 cells) treatment significantly inhibits the growth of U937 cells in a concentration-dependent manner[1].
K145 (10 μM; 24 hours; U937 cells) treatment significantly induces apoptosis in U937 cells[1].
K145 (4-8 μM; 3 hours; U937 cells) treatment decreases the phosphorylation of ERK and Akt[1].
Treatment with K145 (10 μM) causes a decrease of total cellular S1P without significant effects on ceramide levels[1].
