Human pancreatic cancer cells display different sensitivities to the synthetic IAP antagonist, AZD5582. Treating human pancreatic cancer cells with AZD5582 differentially induces apoptosis, dependent on the expression of p-Akt and p-XIAP. It targets cIAP1 to induce TNF-α-induced apoptosis. AZD5582 induces a decrease of Mcl-1 protein, a member of the Bcl-2 family, but not that of Bcl-2 and Bcl-xL[1]. HNSCC (head and neck squamous cell carcinoma) cell lines SCC25, Cal27, and FaDu show a dose-dependent cytotoxic effect after treatment with AZD5582[2]. |

| In vivo | After AZD5582 treatment, tumor growth and weight decrease, whereas cleaved caspase 3 expression increases in Panc-1-derived xenograft model[1]. When administered intravenously to MDA-MB-231 xenograft-bearing mice, AZD5582 results in cIAP1 degradation and caspase-3 cleavage within tumor cells and causes substantial tumor regressions following two weekly doses of 3.0 mg/kg. Following a modest 0.5 mg/kg intravenous bolus dose of AZD5582 in mice, unbound plasma levels remain above the concentrations at which apoptosis induction and cell death are observed in MDA-MB-231 cells over the course of several hours. Although cIAP1 degradation happens very quickly upon exposure to AZD5582 in vivo, apoptosis induction (as measured by the amount of cleaved caspase-3) takes longer to reach a maximal effect. A single agent AZD5582 does not exhibit broad-based cytotoxicity but instead should be employed in selected tumor settings expected to be sensitive to IAP inhibitors or in rational combinations with other targeted therapies. The dihydrochloride salt of AZD5582 has sufficient aqueous solubility (>7 mg/mL at pH 4−6) to enable formulation for intravenous administration at the projected efficacious doses. With respect to chemical stability, AZD5582 is found to be photostable and hydrolytically stable between pH 4−6, although some amide hydrolysis is observed under strongly acidic (pH < 1) and basic (pH > 8) conditions. In addition, the compound is stable in the plasma of multiple species, with no compound degradation observed after several hours under physiological conditions[3]. |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × 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).
Dilution Calculator
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.
