4-Aminobenzamidine dihydrochloride causes a dose-dependent inhibition of uPA activity in DU145 cells[2].
4-Aminobenzamidine dihydrochloride has an anti-proliferative effect in DU145 cells. 4-Aminobenzamidine (100-250 μM, 24 h) abolishes rat hepatocyte proliferation induced by plasminogen and EGF[2][3].
4-Aminobenzamidine (1-100 μM) dihydrochloride induces a dose-dependent vasodilator effect in intact endothelium aortic rings from Wistar and SHR[4].
4-Aminobenzamidine (1 nM) dihydrochloride evokes coronary vasodilation in the isolated hearts of Wistar rats and SHR[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
4-Aminobenzamidine (0.01-10 μg/kg; i.v.; 5-min interval between each dose injection. 1mg/kg; p.o.; daily for 60 days) dihydrochloride prevents the progress of hypertension, improved endothelial function, and attenuated the cardiac remodeling in hypertensive rats[4].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1 mg/mL (4.81 mM); Clear solution
This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 1 mg/mL (4.81 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 1 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
