Biological Activity
| Targets | SM-433, a Smac mimetic, function as inhibitor of inhibitor of apoptosis proteins (IAPs). XIAP BIR3 protein exhibits strong binding affinity for SM-433 with an IC50<1 μM [1]. |
| ln Vitro | SM-433 demonstrates strong inhibitory action on SK-OV-3 ovarian cancer cells and MDA-MB -2131 human breast cancer cells (IC50 <10 μM, respectively) [1]. |

Solubility Data
| Solubility (In Vitro) | DMSO: ~160 mg/mL (~284.8 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 4 mg/mL (7.12 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 40.0 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: ≥ 4 mg/mL (7.12 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 40.0 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: ≥ 4 mg/mL (7.12 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 40.0 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.) |
