AZD-9833 is a novel, highly potent and orally bioavailable SERD (Selective Estrogen Receptor Degrader) and ER Antagonist. AZD-9833 is used for the study of ER+ HER2-advanced breast cancer. AZD-9833 was demonstrated to be a highly potent SERD that showed a pharmacological profile comparable to fulvestrant in its ability to degrade ERα in both MCF-7 and CAMA-1 cell lines. A stringent control of lipophilicity ensured that AZD-9833 had favorable physicochemical and preclinical pharmacokinetic properties for oral administration.
| ln Vitro |
The extract of camistrant is taken from US20180111931A1, Example 17[1].

| ln Vivo |
In human parental MCF7 mice xenografts, camizestrant (oral; 0.2–50 mg/kg; 20 days) demonstrates dose-dependent antitumor effectiveness [1]. Tumor growth is reduced by camistrant (oral; 0.8–40 mg/kg; 30 days) in a dose-dependent manner. At doses more than 10 mg/kg, it virtually totally prevents tumor growth in mice [1].

| Animal Protocol |
Animal/Disease Models: Human ESR1 mutated breast cancer patient-derived female NSG mouse CTC174 cell xenograft [1]
Doses: 0.8 mg/kg, 3 mg/kg, 10 mg/kg, 20 mg/kg, 40 mg/kg given Medication: Oral administration; 30 days; one time/day. Experimental Results: Inhibited tumor growth in a dose-dependent manner. |

| Additional Infomation |
Camizestrant is an orally available selective estrogen receptor degrader (SERD), with potential antineoplastic activity. Upon administration, camizestrant binds to the estrogen receptor (ER) and induces a conformational change that results in the degradation of the receptor. This prevents ER-mediated signaling and inhibits the growth and survival of ER-expressing cancer cells.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 7.5 mg/mL (15.74 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 75.0 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: 7.5 mg/mL (15.74 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 75.0 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.
