Sphingosine kinase 1 (SphK1) enzyme catalyzes the phosphorylation of sphingosine into sphingosine-1-phosphate (S1P). S1P plays an important role in diverse biological processes. In numerous human cancers, overexpression of SphK1 led to the severity of disease, drug resistance and reduced patient survival. Furthermore, SphK1 increased activity was connected to play a crucial role in immunological responses such as asthma, rheumatoid arthritis and sepsis. Inhibitors of SphK1 enzyme helps in reducing the adverse effects caused by over expression of SpkH1. Hence, there is a growing demand for the discovery of new SphK1 inhibitors. Curcumin (5) a major constituent of turmeric rhizomes, displayed the inhibition activity of cancers by regulating multiple cellular signaling pathways. Henceforth, the present molecular docking study suggested that curcumin (5) could be valuable SphK1 inhibitor as a result of its binding affinity to the SphK1 active site similar to that of CTK8F1052 (4). Further exploration of curcumin (5) efficacy in inhibiting the SphK1 activity is necessary to support computational docking findings.
