Chemical Properties
Off-White Solid
Usage
Triciribine is an antitumor tricyclic nucleoside. Triciribine acts as a potent, small-molecule inhibitor of AKT phosphorylation in subjects with solid tumors contining activated AKT. Triciribine is al
so a selective inhibitor of HIV-1 and HIV-2, including strains known to be resistant to AZT or TIBO.
Biological Activity
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-3 β and AFX. In vitro, induces apoptosis and growth arrest preferentially in human cancer cells with elevated levels of Akt. In mice, potently and selectively inhibits growth of Akt-overexpressing tumors. Inhibits DNA synthesis and displays antiviral activity against HIV-1 and-2.

Definition
ChEBI: Triciribine is a nucleoside analogue in which the nucleobase portion is a 1,4,5,6,8-pentaazaacenaphthylene ring system substituted with an amino group at position 3, and a methyl group at position 5 and is bound to the beta-D-ribofuranosyl moiety by an N(1)-glycosidic linkage. It has a role as an EC 2.7.1.137 (phosphatidylinositol 3-kinase) inhibitor.
Biochem/physiol Actions
Triciribine is a highly selective Akt/PKB inhibitor, that selectively inhibits the cellular phosphorylation/activation of Akt1/2/3.
