A-674563 is a potent and selective Akt1 inhibitor with IC50 value of 14 nM. A-67453 also inhibited PKA and Cdk2 with IC50 value of 16 nM and 46 nM.
Akt, also known as protein kinase B, is a serine/threonine-specific protein kinase that plays a key role in multiple cellular processes such as glucose metabolism, apoptosis, cell proliferation, transcription and cell migration.
In MiaPaCa-2 cells treated with A-674563 for 48 hour, it slowed the tumor cell proliferation (EC50 = 0.4 μm). In STS cells, phosphorylation of GSK3 and MDM2 was prominently reduced by A-674563 treatment. [1] Akt inhibition-induced G2 cells cycle arrest and apoptosis were also observed in A563-treated STS cells. [2]
In scid mice carrying established PC-3 tumors, administration of A-674563 at 40 mg/kg per day for 21 days, combined with administration of paclitaxel at 15 mg/kg per day on days 20.24.28, increased the efficacy of paclitaxel compared with paclitaxel monotherapy. [1] A563 also significantly blocked HT1080 xenograft growth in nude mice. [2]

Pre-clinical assessment of A-674563 as an anti-melanoma agent.[Pubmed:26970307]
Biochem Biophys Res Commun. 2016 Aug 12;477(1):1-8.
The present study aims to investigate the anti-melanoma activity by an Akt1 specific inhibitor A-674563. We showed that A-674563 was anti-proliferative and cytotoxic when added to human melanoma cells (A375, WM-115 and SK-Mel-2 lines). A-674563 induced caspase-dependent apoptotic death of human melanoma cells, and its cytotoxicity was inhibited with pre-treatment of caspase inhibitors. Further, A-674563 treatment blocked Akt and its downstream S6 Kinase 1 (S6K1) activation in A375 melanoma cells. Significantly, restoring Akt-S6K1 activation via introduction of constitutively-active Akt1 (ca-Akt1) only partially attenuated A-674563's cytotoxicity against A375 cells. Further, A-674563 induced pro-apoptotic ceramide production in A375 cells. Significantly, sphingosine-1-phosphate (S1P) inhibited A-674563-induced ceramide production and subsequent A375 cell apoptosis. On the other hand, co-treatment with the glucosylceramide synthase (GCS) inhibitor PDMP or the cell permeable short-chain ceramide (C6) potentiated A-674563's cytotoxicity against A375 cells. In vivo, A-674563 oral gavage inhibited A375 xenograft growth in severe combined immunodeficiency (scid) mice. Akt inactivation, caspase-3 activation and ceramide production were also observed in A-674563-treated A375 xenografts. Together, these results suggest that A-674563 exerts potent anti-melanoma activity, involving Akt-dependent and Akt-independent mechanisms.
Concurrent targeting Akt and sphingosine kinase 1 by A-674563 in acute myeloid leukemia cells.[Pubmed:26920060]
Biochem Biophys Res Commun. 2016 Apr 15;472(4):662-8.
Akt signaling plays a pivotal role in acute myeloid leukemia (AML) development and progression. In the present study, we evaluated the potential anti-AML activity by a novel Akt kinase inhibitor A-674563. Our results showed that A-674563 dose-dependently inhibited survival and proliferation of U937 AML cells and six lines of human AML progenitor cells, yet sparing human peripheral blood mononuclear leukocytes (PBMCs). A-674563 activated caspase-3/9 and apoptosis in the AML cells. Reversely, the pan-caspase inhibitor z-VAD-CHO dramatically alleviated A-674563-induced AML cell apoptosis and cytotoxicity. For the molecular study, we showed that A-674563 blocked Akt activation in U937 cells and human AML progenitor cells. Further, A-674563 decreased sphingosine kinase 1 (SphK1) activity in above AML cells to deplete pro-survival sphingosine-1-phosphate (S1P) and boost pro-apoptotic ceramide production. Such an effect on SphK1 signaling by A-674563 appeared independent of Akt blockage. Significantly, K6PC-5, a novel SphK1 activator, or supplement with S1P attenuated A-674563-induced ceramide production, and subsequent U937 cell death and apoptosis. Importantly, intraperitoneal injection of A-674563 at well-tolerated doses suppressed U937 leukemic xenograft tumor growth in nude mice, whiling significantly improving the animal survival. The results of the current study demonstrate that A-674563 exerts potent anti-leukemic activity in vitro and in vivo, possibly via concurrent targeting Akt and SphK1 signalings.
