Selective inhibitor of Akt (protein kinase B) signaling; displays minimal inhibition of PKC, PKA, SGK and p38 pathways. Inhibits phosphorylation and activation of downstream targets of Akt including Bad, GSK-3β and AFX. Induces apoptosis and growth arrest in vitro, preferentially in human cancer cells with elevated levels of Akt. Potently and selectively inhibits growth of Akt-overexpressing tumors in mice. Inhibits DNA synthesis and displays antiviral activity against HIV-1 and -2.
