IC50: 1.2 μM (ST-hSK); 11 μM (hERK2)[1]
SKI-I is a potent and selective inhibitor of human sphingosine kinase (SK), with an IC50 of 1.2 μM for ST-hSK. SKI-I also inhibits hERK2 (IC50=11 μM). SKI-I induces apoptosis in tumor cell lines[1][2].
SKI-I (Compound I; 5 μg/mL) inhibits SK activity by 99%[1].
SKI-I (10 μM; 24 h) induces the apoptosis of T24 cells[1].
