Biological Activity
| ln Vitro | The three-promoted polymer complex binds more readily when ARCC-4 improves the protein-protein reaction between AR and VHL [1]. AR can be efficiently degraded by -4 (0.1-10,000 nM; 20 hours), with a D50 of 5 nM and a Dmax of greater than 95% [1]. Molds with ARCC-4 (100 nM; 12 hours) exhibit AR. ARCC-4 does not impede PR-A or PR-B, but it nearly solely modulates AR through chromoplast pigments [1]. Clinically significant AR mutations are effectively suppressed by ARCC-4 [1]. ARCC-4 is still functional in the presence of high androgen levels [1]. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~200 mg/mL (~195.28 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: 5 mg/mL (4.88 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication. 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 (4.88 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. Solubility in Formulation 3: ≥ 5 mg/mL (4.88 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
