The transfer of the gamma phosphate from ATP to sphingosine (Sph) to generate a
small signaling molecule, sphingosine 1-phosphate (S1P), is catalyzed by
sphingosine kinases (SphK), which exist as two isoforms, SphK1 and SphK2. SphK is
a key regulator of S1P and the S1P:Sph/ceramide ratio. Increases in S1P levels
have been linked to diseases including sickle cell disease, cancer, and fibrosis.
Therefore, SphKs are potential targets for drug discovery. However, the current
chemical biology toolkit needed to validate these enzymes as drug targets is
inadequate. With this review, we survey in vivo active SphK inhibitors and
highlight the need for developing more potent and selective inhibitors.
