Biological Activity
| ln Vitro | MDA-MB-231 cell viability can be efficiently and considerably reduced by D-Cl-amidine hydrochloride (200–400 μM) [1]. Caspases 3 are activated more by D-Cl-amidine hydrochloride, suggesting that PAD1 inhibition results in a higher rate of apoptosis [1]. |
| ln Vivo | After being injected intravenously at a dose of 2.5 mg/kg, D-Cl-amidine hydrochloride was still detectable in serum at values of about 10 nM after 4 hours and about 21 nM after 2 hours. At 4 hours, D-Cl-amidine hydrochloride was still detected in blood at a concentration of less than 10 nM when given intraperitoneally at a dose of 10 mg/kg [1]. |

Solubility Data
| Solubility (In Vitro) |
DMSO :~80 mg/mL (~230.39 mM) H2O :~16.67 mg/mL (~48.01 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.67 mg/mL (7.69 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 26.7 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: ≥ 2.67 mg/mL (7.69 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 26.7 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: ≥ 2.67 mg/mL (7.69 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 26.7 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. Solubility in Formulation 4: 10 mg/mL (28.80 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication.  (Please use freshly prepared in vivo formulations for optimal results.) |
