| Bioactivity | GSK-626616 is a potent, orally bioavailable inhibitor of DYRK3 (IC50=0.7 nM). GSK-626616 inhibits other members of the DYRK family (e.g., DYRK1A and DYRK2) with similar potency, which is a potential therapy for the treatment of anemia[1]. | ||||||||||||

| Invitro | GSK-626616 abolishes the phosphorylation of S6K1 at Thr389 in nonstimulated HeLa cells. GSK-626616 reduces the phosphorylation of S6K1 at Thr389 in EGF- and insulin-stimulated HeLa cells, showing that mTORC1 activity is impaired[2].GSK-626616 (serum-deprived HeLa cells) reduces EGF-induced phosphorylation of PRAS40 at Thr246. Binding of PRAS40 to mTORC1 is enhanced by GSK-626616[2]. | ||||||||||||
