a potent selective protein kinase B/Akt inhibitor with an IC50 of 14 nM. activity against PKA and CDK2 with IC50 of 16 and 46 nM, respectively. While observed in vivo, A-674563 indicated significantly effects on depolarization of assay and severe CV toxicity (e.g. hypotension) in vivo. An X-ray structure of kinase A, which has 80% homology with Akt in the kinase domain, suggested bound in the ligand-protein complex. The Akt inhibitor A-674563 displayed
