Mechanism of Action

Targets/IC₅₀/Ki	HIV-1 (CEM-SS, H9, H9IIIB, U1 cells) 20 nM Akt (PC3 cells) 130 nM
In vitro	Triciribine (API-2) exhibits maximum growth inhibition around 1-10 μM and inhibits phosphorylation of Akt, as well as downstream p70S6K, to basal levels at 100μM (IC50 = 130 nM). It shows particular promise for inhibiting growth in Nf1 and Trp53 mutant astrocytoma cells in a grade-dependent manner. The WHO II K1861-10 line is inhibited, incompletely (69% maximum inhibition), with a GI50 value of 1.7 μM for this compound, whereas higher-grade tumor lines (KR158, KR130, and SF295) are inhibited to a greater extent (>80% maximum inhibition) at lower GI50 values (0.4–1.1 mM). Importantly, it is much less effective at inhibiting primary astrocytes (GI5013.6 mM), suggesting that this inhibitor may show specificity for tumor cells. It inihibits HIV-1with an IC50 of 20 nM. Greater than 90% inhibition is achieved at 0.1μM and complete inhibition of syncytia formation is achieved at 5μM. Associated cell toxicity in the same cell line for Triciribine is 46 μM, resulting in selectivity indices of 2250. It markedly inhibits HIV-1-induced p24 core antigen production, reverse transcriptase, and infectious virus production in a dose-dependent manner using HIV-1 acutedly infected CEM-SS, H9, and persistently infected H9III _B and U1 cells. This compound inhibits Akt phosphorylation at Thr308 and Ser473 and Akt activity in the human prostate cancer cell line PC-3. It sensitizes PC-3 cells to TRAIL- and anti-CD95-induced apoptosis, whereas the cells remain resistant to DNA damaging chemotherapeutics. It is highly selective for Akt and does not inhibit the activation of phosphatidylinositol 3-kinase, phosphoinositide-dependent kinase-1, protein kinase C, serum and glucocorticoid-inducible kinase, protein kinase A, signal transducer and activators of transcription 3, extracellular signal-regulated kinase-1/2, or c-Jun NH2-terminal kinase.
Kinase Assay	Akt Phosphorylation Changes Assay
Kinase Assay	Cells are grown to 80%–90% confluency and stimulated for 5–10 minutes with 1–10 ng/mL of epidermal growth factor or platelet derived growth factor (PDGF)–AA with or without 10–20 mM of U0126 or LY-294002. Protein lysates (5–20 μg) are separated by 12%–15% SDS PAGE and analyzed by Western blot for Akt, phosphorylated Akt (phospho-Ser 473), MAPK, and phosphorylated MAPK (p44/42 phospho-Thr202/Tyr204) antibodies (1:1000).
In vivo	Triciribine (API-2), administered at 1 mg/kg/day i.p., inhibits tumor growth by 90%, 88%, and 80% in nude mice bearing OVCAR3, OVCAR8, and PANC1 tumors, respectively, which overexpress Akt. However, this compound has little effect on the growth of OVCAR5 and COLO357 cells.
