GSK2110183 hydrochloride is an orally bioavailable, selective, ATP-competitive and potent pan-Akt kinase inhibitor with Kis of 0.08/2/2.6 nM for Akt1/Akt2/Akt3 respectively.
GSK2110183 is an ATP competitive, time dependant and fully reversible inhibitors of the Akt kinase family. GSK2110183 has a Ki of 0.08, 2 and 2.6 nM against Akt1, Akt2 and Akt3, respectively. GSK2110183 inhibits the kinase activity of the E17K Akt 1 mutant protein in a standard kinase assay with EC50 of 0.2 nM[1].
Mice bearing BT474 breast tumor xenografts are dosed orally with either vehicle or GSK2110183 at 10, 30 or 100 mg/kg daily for 21 days which result in 8, 37 and 61% TGI, respectively. Mice tolerated GSK2110183 well, with 1-3% body weight loss reported after 5 days of dosing which recover over the course of the study. Other tumor xenograft models which possess an activation of the Akt pathway are explored to further demonstrate compound efficacy. Mice treated with GSK2110183 at 10, 30 and 100 mg/kg result in 23, 37 and 97% TGI, respectively, of SKOV3 xenografts[1].
