SLR080811 is a SphK 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.

ACT-672125 is a Potent CXCR3 Antagonist with Therapeutic Potential in Autoimmune Diseases. ACT-672125 showed good physicochemical properties and safety profile. In a proof-of-mechanism model of lung inflammation, ACT-672125 inhibited the recruitment of CXCR3 expressing T cells into the inflamed lung in a dose-dependent manner.
