tas303

SLP120701 is a potent and selective sphingosine kinase 2 inhibitor. Sphingosine-1-phosphate (S1P) is a ubiquitous, endogenous small molecule that is synthesized by two isoforms of sphingosine kinase (SphK1 and 2). Intervention of the S1P signaling pathway has attracted significant attention because alteration of S1P levels is linked to several disease states including cancer, fibrosis, and sickle cell disease.

TAS-303 is a selective norepinephrine reuptake inhibitor which displays significant norepinephrine transporter (NET) inhibitory activity toward serotonin or dopamine transporters. Radioligand-binding studies showed that TAS-303 selectively and potently inhibited [3H]norepinephrine binding to the human NET.
