cIAP1
PROTAC AR Degrader-4 targets the androgen receptor (AR). It contains an AR binding group and an IAP ligand that recruits cellular inhibitor of apoptosis protein 1 (cIAP1). This molecule is a degrader that induces AR ubiquitination and degradation via the ubiquitin-proteasome pathway by bringing the AR into proximity with cIAP1. |

| ln Vitro |
IAPs-dependent Protein Erasers that are Specific and Nongenetic (SNIPERs) are two-component compounds that are created by combining an IAPs recognition structure with a target protein recognition structure. Three processes are involved in directing protein breakdown. 1. SNIPER's two recognition structures enable the formation of a complex that binds the target protein to IAPs, which contain E3 ligase activity. IAPs cause the target protein to become polyubiquitinated. 3. Proteases breakdown the polyubiquitinated protein.
PROTAC AR Degrader-4 is an AR degrader that incorporates an IAP ligand binding group, a linker, and an AR binding group. It is an AR degrader. The compound is a SNIPER that induces degradation of the androgen receptor. In vitro, it is expected to reduce AR protein levels in AR-positive prostate cancer cell lines. |
| ln Vivo |
In vivo, PROTAC AR Degrader-4 is designed to degrade the androgen receptor (AR). This activity has the potential to inhibit tumor growth in AR-dependent prostate cancer models. As a cIAP1-based degrader (SNIPER), it can effectively reduce AR protein levels in vivo, similar to other AR degraders.
|
| Enzyme Assay |
PROTAC AR Degrader-4 is a complete molecule. A cell-free binding assay is not typical for a full PROTAC. Researchers could use SPR or TR-FRET to confirm the binding of its individual components to their targets. A biochemical assay could measure the binding of the compound to the AR and to cIAP1, but its degradation activity requires a cellular context.
|
| Cell Assay |
Prostate cancer cells (e.g., LNCaP or VCaP) are seeded in 6-well plates and treated with PROTAC AR Degrader-4 TFA at various concentrations for 24-48 hours. After treatment, cells are lysed, and protein lysates are analyzed by Western blotting using an anti-AR antibody. The DC50 (concentration for 50% degradation) can be calculated from the densitometry data.
|
| Animal Protocol |
A standard in vivo animal protocol for PROTAC AR Degrader-4 would involve a mouse xenograft model of prostate cancer. Male athymic nude mice are implanted subcutaneously with LNCaP or VCaP cells. When tumors reach 100-150 mm3, mice are randomized and treated intraperitoneally with the degrader. Tumor volume is measured bi-weekly. AR degradation in tumors is confirmed by IHC.
|
| ADME/Pharmacokinetics |
PROTAC AR Degrader-4 TFA has a molecular weight of 884.03 and a molecular formula of C45H68F3N3O11. It is a solid that should be stored at -20degC for up to 3 years. In solution, it is stable for 1 year at -80degC. The TFA salt enhances solubility. Specific PK data are not available.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 5 mg/mL (5.66 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 50.0 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: 5 mg/mL (5.66 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 50.0 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.  (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
