PF-543 has been known as a substance that strongly inhibits SK1. However, it also exhibits antineoplastic activity that is lower than other inhibitors of SK1. In this study, we compared PF-543 and synthesized a newly designed derivative of PF-543 (compound 2) in which two aromatic structures were connected in para-form. The synthesized derivative showed inhibitory effect on SK1, similar to that of PF-543. However, it was more cytotoxic to HT29, AGS, and PC3 cells than PF-543. We also carried out a docking study for SK1 and demonstrated that the synthesized derivative showed interaction with SK1 similar to PF-543. Results obtained from this study suggest that the structure of compound 2 may be well substituted for the structure of PF-543 in terms of biological activity, providing us important structural information for the design of new derivatives of PF-543.
