K145

K145 Chemische Eigenschaften,Einsatz,Produktion Methoden

• Biologische Aktivität

  K145 is a selective, substrate-competitive and orally active SphK2 inhibitor with IC50 of 4.3 μM and Ki of 6.4 μM.It is inactive against SphK1 and other protein kinases,it induces apoptosis and has potent antitumor activity.

• in vitro

  K145 (0-10 μM; 24-72 hours; U937 cells) treatment significantly inhibits the growth of U937 cells in a concentration-dependent manner.
  K145 (10 μM; 24 hours; U937 cells) ) treatment significantly induces apoptosis in U937 cells.
  K145 (4-8 μM; 3 hours; U937 cells) treatment decreases the phosphorylation of ERK and Akt.
  Treatment with K145 (10 μM) causes a decrease of total cellular S1P without significant effects on ceramide levels.
