Description

A cell-permeable and reversible quinoxaline compound that potently and selectively inhibits Akt1/Akt2 activity (IC50 = 58 nM, 210 nM, and 2.12 microM for Akt1, Akt2, and Akt3, respectively, in in vitro kinase assays). The inhibition appears to be pleckstrin homology (PH) domain-dependent. It does not exhibit any inhibitory effect against PH domain-lacking Akts, or other closely related AGC family kinases, PKA, PKC, and SGK, even at concentrations as high as 50 microM. Overcomes Akt1/Akt2-mediated resistance to chemotherapeutics in tumor cells and is shown to block basal and stimulated phosphorylation/activation of Akt1/Akt2 both in cultured cells in vitro and in mice in vivo. A 10 mM (1 mg/181 microl) solution of Akt Inhibitor VIII, Isozyme-Selective, Akti-1/2 (Cat. No. 124017) in DMSO is also available., A cell-permeable, reversible, potent, and selective inhibitor of Akt1/Akt2 activity (IC50 = 58 nM, 210 nM, and 2.12 microM for Akt1, Akt2, and Akt3, respectively, in in vitro kinase assays). The inhibition is reported to be pleckstrin homology (PH) domain-dependent. It does not exhibit any inhibitory effect against PH domain-lacking Akts, or other closely related AGC family kinases, PKA, PKC, and SGK, even at concentrations as high as 50 microM. Overcomes Akt1/Akt2-mediated resistance to chemotherapeutics in tumor cells and is shown to block basal and stimulated phosphorylation/activation of Akt1/Akt2 both in cultured cells in vitro and in mice in vivo.
