Sphingosine 1-phosphate (S1P), a product of sphingosine kinases (SphK), mediates diverse biological processes such as cell differentiation, proliferation, motility, and apoptosis. In an effort to search and identify specific inhibitors of human SphK, the inhibitory effects of synthetic sphingoid analogs on kinase activity were examined. Among the analogs tested, we found two, SG12 and SG14, that have
鞘氨醇激酶(SphK)的产物鞘氨醇1-磷酸酯(S1P)介导多种生物过程,例如细胞分化,增殖,运动和凋亡。为了寻找和鉴定人SphK的特异性抑制剂,研究了合成类鞘氨醇类似物对激酶活性的抑制作用。在测试的类似物中,我们发现了两个SG12和SG14,它们对hSphK2具有特异性抑制作用。N,N-二甲基鞘氨醇(DMS)是一种著名的SphK抑制剂,对SphK1和SphK2以及蛋白激酶C均表现出抑制作用。相反,SG12和SG14对hSphK2表现出选择性抑制作用。此外,第14研究组不影响PKC。在分离的血小板中,SG14显着阻止了鞘氨醇向1-磷酸鞘氨醇的转化。
