MDV3100 (Enzalutamide) is an oral inhibitor of androgen receptor (AR) with an IC50 value of 36nM[1]. MDV3100 blocks AR interaction, inhibits translocation of the AR to the nucleus, impairs AR binding to DNA, and inhibits coactivator recruitment and receptor-mediated DNA transcription[2]. MDV3100 has been widely used to induce mitochondrial autophagy and inhibit the proliferation of prostate cancer cells[3].
In vitro, MDV3100 treatment for 144 hours significantly inhibited the proliferation of CW22Rv1 cells, with an IC50 value of 9.7μM[4]. Treatment with 100µM MDV3100 for 48 hours significantly inhibited the growth of AR-positive LNCaP cells, inducing nuclear condensation and fragmentation of DNA[5]. Treatment with 10µM MDV3100 for 72 hours significantly reduced the migration ability of MDA-MB-453 cells and downregulated the transcription factors AP-1 and SP-1[6].
In vivo, MDV3100 treatment via oral administration at a dose of 100mg/kg/day for 21 days reduced bone mass in the axial skeleton of male mice[7]. Oral administration of MDV3100 at a dose of 100mg/kg daily for 28 days reduced the tumor volume of LNCaP-AR xenograft tumors in mice and induced apoptosis of tumor cells[8].

Protocol
| Cell experiment [1]: | |
|
Cell lines |
CW22Rv1 cells |
|
Preparation Method |
CW22Rv1 cells were cultured in RPMI-1640 medium supplemented with 10% fetal bovine serum (FBS), and 1% penicillin-streptomycin at 37°C in 5% CO2/atmosphere. CW22Rv1 cells were seeded onto 96-well microplates (5×103 cells/well) and cultured for 24h. Cells were treated with the different concentrations of MDV3100 (0, 0.5, 1, 5, 10, 50, and 100μM) for 144h, cell viability was assessed. |
|
Reaction Conditions |
0, 0.5, 1, 5, 10, 50, and 100μM; 144h |
|
Applications |
MDV3100 treatment decreased the cell viability of CW22Rv1 cells in a dose-dependent manner. |
| Animal experiment [2]: | |
|
Animal models |
Male CB17SCID mice |
|
Preparation Method |
Male CB17SCID mice (6 weeks old) were housed under controlled temperature (21-23°C), humidity (30-35%) and light cycle (7:00 AM to 7:00 PM) and maintained on a standard rodent diet. LNCaP-AR cells were prepared by the addition of trypsin-EDTA, washed with medium, collected and resuspended at 2×107 cells/ml. Cell suspensions were diluted with Matrigel to 2×106 cells/0.2 ml and delivered subcutaneously in the suprascapular region of mice. Tumor growth was monitored to the volume of 100mm3 when treatment began (80 days). The observed rate of tumor take with LNCaP-AR cells is between 70% and 80%. Body weight and tumor volumes (width2×length/2) were measured two times per week with a digital caliper, and the average tumor volumes were determined. MDV3100 was diluted in Tween 80:PEG 400, and stored at 4°C until administration by oral gavage. Mice were treated daily for 28 consecutive days with 50mg/kg MDV3100, vehicle control, or 50mg/kg bicalutamide. |
