| In vitro |
Enzalutamide has greater affinity to AR than Bicalutamide does in a competition assay with 16β-[18F]fluoro-5α-DHT (18-FDHT) in castration-resistant LNCaP/AR cells (AR-overexpressing). While Enzalutamide shows no agonism in LNCaP/AR prostate cells. Enzalutamide antagonizes induction of prostate-specific antigen (PSA) and transmembrane serine protease 2 (TMPRSS2), combination with the synthetic androgen R1881 in parental LNCaP cells. Enzalutamide could inhibit the transcriptional activity of a mutant AR protein (W741C, mutation of Trp741 to Cys). [1] Enzalutamide also prevents nuclear translocation and co-activator recruitment of the ligand-receptor complex. [2] |

AR reporter assay: Enzalutamide is evaluated by an artificial AR response reporter system in a hormone refractory prostate cancer cell line. In this system, the prostate cancer LNCaP cells are engineered to stably express about 5-fold higher level of AR than endogenous level. The exogenous AR has similar properties to endogenous AR in that both are stabilized by a synthetic androgen R1881. The AR-over expressed cells are also engineered to stably incorporate an AR response reporter and the reporter activity of these cells shows features of hormone refractory prostate cancer. The antagonistic activity of Enzalutamide is tested in the presence of 100 pM of R1881. Engineered LNCaP cells are maintained in Iscove's medium containing 10% fetal bovine serum (FBS). Two days prior to Enzalutamide treatment, the cells are grown in Iscove's medium containing 10% charcoal-stripped FBS (CS-FBS) to deprive of androgens. The cells are split and grown in Iscove's medium containing 10% CS-FBS with 100 pM of R1881 and increasing concentrations of Enzalutamide. After two days of incubation, reporter activities are assayed. |

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.

Question 1:
I would like to inquire about the usage or solubility of S1250, Enzalutamide.
-
Answer:
For in vivo experiment, S1250 can be dissolved in 2% DMSO+30% PEG 300+ddH2O at 5mg/ml as a suspension for oral gavage. And it can be dissolved in 15% DMSO+85% PEG 300 at 10mg/ml as a clear solution. When prepare the solution, please dissolve the compound in DMSO clearly first, then add PEG.
