|Description||AZD3514 is a potent and oral androgen receptor downregulator with Ki of 2.2 μM and has ability of reducing AR protein expression.Phase 1.|
AZD3514 binds to the AR ligand binding domain and has selectivity for binding to AR over other nuclear hormone receptors. In vitro AZD3514 inhibits cell growth in prostate cancer cells expressing wild-type (VCaP) and mutated (T877A) AR (LNCaP), but is inactive in AR-negative prostate cancer cells. AZD3514 causes a rapid reduction in PSA synthesis in vitro; with a significant decrease in PSA mRNA being evident in LNCaP cells within 2-3 h of compound treatment. AZD3514 inhibits an androgen-induced translocation of AR from the cytoplasm to the nucleus within a comparable time-frame in LNCaP cells and U2OS AR-transfected cells. AZD3514 treatment also reduces AR protein in LNCaP cells maintained in steroid-depleted conditions; an effect which is evident within 6-8 h, and maximal at 18-24 h. The ability to down-regulate AR under such conditions differentiates AZD3514 from the AR antagonists bicalutamide and Enzalutamide, which do not reduce AR protein levels. 
|In vivo||Oral administration of AZD3514 (100mg/kg once-daily for 7 days) significantly inhibits testosterone-induced growth of sexual accessory organs. The mode of action of AZD3514 is associated with loss of AR function. Administration of AZD3514 (100 mg/kg/day orally) for 3 days to Copenhagen rats bearing R3327H Dunning prostate tumours, indicates that AZD3514 treatment also reduces tumour AR in vivo. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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 SDS / 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 SDS / 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.
