AS-2863619 is a dual inhibitor of cyclin-dependent kinase 8 (Cdk8) and Cdk19 (IC50s = 0.6 and 4.3 nM, respectively).1 It induces Foxp3 expression in isolated mouse na?ve T cells when used at a concentration of 1 ?M alone or synergistically in combination with TGF-β. AS-2863619 (30 mg/kg) decreases ear edema and induces production of Foxp3+ regulatory T cells (Tregs) in mice. It also reduces disease severity in a mouse model of experimental autoimmune encephalomyelitis (EAE).
