|Description||Embelin, a quinone isolated from the Japanese Ardisia herb, is an inhibitor of X-linked inhibitor of apoptosis (XIAP) with IC50 of 4.1 μM in a cell-free assay.|
Embelin from the Japanese Ardisia herb is a small-molecular inhibitor that binds to the XIAP BIR3 domain with which Smac and caspsase-9 bind. Embelin inhibits cell growth of both PC-3 and LNCap cells in a dose-dependent manner, with IC50 values of 3.7 and 5.7 μM. While, the toxicity of Embelin in normal PrEC and in WI-38 cells is much lower with IC50 values of 20.1 μM and 19.3 μM. Treatment of PC-3 cells with 25 and 50 μM of embelin for 48 h, 30% and 75% of cells undergo apoptosis, representing approximately 3-and 9-fold increase as compared to untreated cells.  Embelin also potently suppresses the biosynthesis of eicosanoids by selective inhibition of 5-lipoxygenase (5-LO) and Microsomal prostaglandin E2 synthase-1 (mPGES-1) with IC50 = 0.06 and 0.2 mM, respectively. 
Fluorescence Polarization Competitive Binding Assay:Fluorescence polarization experiments are performed in Dynex 96-well, black, round-bottom plates. A 5 μL sample of Embelin dilutions in DMSO, and preincubated XIAP BIR3 protein (0.06 μM) and the N terminus of a Smac peptide (SM7F) (0.01 μM) in the assay buffer are added to 96-well plates to produce a final volume of 125 μL. For each assay, the bound peptide control containing XIAP BIR3 protein and SM7F (equivalent to 0% inhibition) and free peptide control containing only free SM7F (equivalent to 100% inhibition) were included. The plates were mixed and incubated at room temperature for 3 h to reach equilibrium.

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.
