AZD3514 (AZD-3514; AZD 3514) is a novel, potent and orally bioavailable androgen receptor downregulator with potential anticancer activity. It inhibits AR with Ki of 2.2 μM and has the ability to reduce AR protein expression and thus has the potential to be used as an anticancer agent. In LNCaP and LAPC4 prostate cancer cells, AZD3514 inhibited DHT-driven proliferation of LNCaP cells in a dose-dependent way and inhibited the ligand-driven expression of AR-regulated genes PSA and TMPRSS2. Also, AZD3514 reduced AR protein expression in a dose-dependent way. AZD3514 is being studied in a Phase I clinical trial to treat patients with castrate-resistant prostate cancer.
| ln Vitro |
AZD3514 (0-10 μM/L; 7 d) suppresses the growth of LNCaP and LAPC4 cells[2]. AZD3514 (0-10 μM/L; 24 h) suppresses known AR-regulated gene ligand-driven expression[2]. In LNCaPs and LAPC4s, AZD3514 (0-30 μM/L; 24 h) decreases AR protein expression[2]. In LNCaP cells, AZD3514 (1–10 μM/L; 2 h) decreases AR nuclear translocation[2].

| ln Vivo |
Rats' AR signaling is inhibited by AZD3514 (10-100 mg/kg; po once daily for 6 days)[2]. For 30 days, AZD3514 (50 mg/kg, po once daily) slows the growth of prostate tumors[2]. In vivo, AZD3514 (50–100 mg/kg; po once daily for three days) dramatically lowers nuclear AR protein[2].

| Animal Protocol |
Animal/Disease Models: Intact or castrat 42- and 49-day-old Hans Wistar rats[2]

Solubility in Formulation 1: ≥ 2.5 mg/mL (4.81 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (4.81 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
