Sphingosine kinase (SphK) is primarily responsible for the production of Sphingosine-1phosphate (S1P) that plays an important role in many biological and pathobiological processes including cancer, inflammation, neurological and cardiovascular disorders. Most research has focused on developing inhibitors of SphK1 rather than inhibitors of the other isoform SphK2 which has great importance in several pathophysiologic pathways. Exploration of new analogues for improving the potency and selectivity of SphK2 is highly demand. We now have designed, synthesized, and evaluated eighteen new 1,2,3-triazole analogues for their SphK2 inhibitory activity using a ADP-Glo kinase assay and their in vivo anti-tumor bioactivity. Several compounds including 21c, 21e, 21g, 25e-h, 29a-c have high selectivity for SphK2 over SphK1; compound 21g displayed the highest potency with an IC50 value of 0.23 µM. In addition, three compounds 21a, 21b, and 25b have the highest anti-tumor activity on cell viability against U-251 MG human glioblastoma cells. Molecular modeling study was performed to elucidate that polar head group and 1,2,3-triazole pharmacophore impact on the SphK2 selectivity. A novel class of new selective SphK2 inhibitors have been identified. Compound 21g displayed the highest SphK2 inhibitory activity, and compound 25b exhibited highest anti-tumor activity against human malignant glioblastoma tumor U-251 MG cell line.
