Abstract

3-(2-amino-ethyl)-5-[3-(4-butoxyl-phenyl)-propylidene]-thiazolidine-2,4-dione (K145) is identified as a selective SphK2 Inhibitor. It was previously reported as an anti-tumor agent, in this study we demonstrated that K145 was able to regulate hepatic gluconeogenesis and improve glucose intolerance in mice. C57BL/6 mice treated with dexamethasone injection were used as experimental Animals, which exhibited impaired glucose tolerance and increased gluconeogenetic Enzymes. After K145 treatment, we found that the impairment of glucose tolerance and gluconeogenetic genes mRNA expression were improved. Besides, both in vivo and in votro studies suggested that K145 stimulated Insulin dependent Akt phosphorylation and subsequently activates FoxO1 phosphorylation therefore inhibited gluconeogenetic genes expression including PEPCK and G6pase. Our study figures out a potential extent increase the value of developing K145 as therapeutic candidate for diabetes.
