We recently reported a structure-activity relationship study of 4-epi-jaspine B derivatives toward sphingosine kinase (SphK) and identified selective inhibitors of two SphK isoforms. In this study, we designed and synthesized jaspine B regioisomers on the basis of palladium-catalyzed tetrahydrofuran formation and late-stage cross metathesis reactions to investigate the influence of the substitution

四氢呋喃形成和后期交叉易位反应设计和合成了茉莉B区域异构体,以研究官能团的取代位置对SphK抑制的影响。对jaspine B区域异构体SphK抑制活性的评估表明,这些化合物中的几种表现出与4- epi- jaspine B相当的SphK1 / 2抑制能力。
