Cell survival was determined using a WST-1 assay in the human lung cancer cells A549 A. and NCI-H358 B. following treatment with either an AKT1 specific inhibitor, A-674563 (black circle and line) or a pan-AKT inhibitor MK-2206 (gray square and line). *p < 0.05.

Akt1 and Akt2 isoforms are required for Wnt5a-induced RhoA activity. a, c Human osteosarcoma cells MG-63 (a) and U20S (c), serum-deprived for 24 h, were pre-treated with 10 nmol/L MK-2206 (Akt inhibitor) for 1 h, were incubated with 100 ng/mL Wnt5a and harvested at 30 min after the start of Wnt5a treatment. The relative RhoA activity was normalized to the average value of LY294002/Wnt5a-untreated group. b, d Serum-deprived MG-63 (b) and U20S cells (d) were pre-treated with 10 nmol/L A-674563 (Akt1 inhibitor) and 10 nmol/L CCT128930 (Akt2 inhibitor) for 1 h, then were incubated with 100 ng/mL Wnt5a and harvested at 30 min after the start of Wnt5a treatment. Data were presented as mean ± SD of 3 determinations. The relative RhoA activity was normalized to the average value of each inhibitor-untreated group

|Description||A-674563 is an Akt1 inhibitor with Ki of 11 nM in cell-free assays, modest potent to PKA and >30-fold selective for Akt1 over PKC.|
|Features||Orally bioavailable compound (achieved by replacing indole of A-443654 with phenyl moiety) and somewhat less selective for Akt over PKA than A-443654.|
A-674563 is achieved from A-443654 by replacing the indole with a phenyl moiety and getting oral activity. A-674563 slows proliferation of tumor cells with EC50 of 0.4 μM.  A-674563 does not inhibit Akt phosphorylation per se, but blocks the phosphorylation of Akt downstream targets in a dose-dependent manner. A-674563 induced Akt blockade results in decreased STS cell downstream target phosphorylation and tumor cell growth inhibiton. A-674563 induces G2 cell cycle arrest and apoptosis in STS cells. 
|In vivo||20 mg/kg A-674563 increases plasma insulin in an oral glucose tolerance test. A-674563 shows no significant monotherapy tumor inhibitory activity; the efficacy of the combination therapy is significantly improved compared to paclitaxel monotherapy.  A674563-treated (20 mg/kg/bid, p.o.) mice exhibits slower tumor growth and more than 50% decrease in the tumor volume at the termination of the study compared with that in control group.  A-674563 is identified to have drastically improved PK profile with oral bioavailability of 67% in mouse, but is 70-fold less active than A-443654. |
Akt Kinase Assay:The kinase assay uses His-Akt1 and a biotinylated mouse Bad peptide as substrate. The kinase assay is carried out at room temperature for 30 minutes in 50 μL of reaction buffer [20 mM HEPES, pH 7.5, 10 mM MgCl2, 0.1% (w/v) Triton X-100, 5 μM ATP (Km = 40 μM), 5 μM peptide (Km = 15 μM), 1 mM DTT, 60 ng of Akt1, and 0.5 μCi of [γ-33P]ATP] in the presence of different concentrations of A-674563. Each reaction is stopped by adding 50 μL of termination buffer (0.1 M EDTA, pH 8.0, and 4 M NaCl). The biotinylated Bad peptides are immobilized on streptavidin-coated FLASH plates. After being washed with PBS-Tween 20 (0.05%), the 33P phosphopeptide captured on the FLASH plates is measured with a TopCount Packard Instruments γ counter.

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
