A fluorescence-labeled sphingosine and sphingosine 1-phosphate have been successfully synthesized from the oxazolidinone methyl ester derived from glycidol via monoalkylation and the stereoselective reduction of the resulting ketone. The labeled sphingosine was converted into its phosphate by treatment with sphingosine kinase 1 (SPHK1) from mouse, and in platelets, and it was incorporated into the
荧光标记的鞘氨醇和鞘氨醇1-磷酸酯已成功地通过单烷基化和立体选择性还原生成的酮,由缩水甘油衍生的恶唑烷酮甲酯合成。通过用小鼠的鞘氨醇激酶1(SPHK1)处理,将标记的鞘氨醇转化为磷酸酯,并在血小板中将其掺入中国仓鼠卵巢(CHO)细胞。此外,NAPK-Sph-1-P通过Edg-1,Sph-1-P受体激活MAPK。
