Barnidipine HCl (Mepirodipine; Y 198561; YM-730; YM09730-5) is a novel and potent calcium channel blocker with antihypertensive effects. As an L-type calcium antagonist (CaA), it has high affinity for [3H] initrendipine binding sites (Ki=0.21 nmol/l), and exhibits selective action against CaA receptors. Barnidipine hydrochloride (Mepirodipine hydrochloride) is an antihypertensive drug and acts by the reduction of peripheral vascular resistance secondary to its vasodilatory action.

Solubility Data
| Solubility (In Vitro) | DMSO : ~250 mg/mL (~473.48 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (3.94 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 20.8 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: ≥ 2.08 mg/mL (3.94 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 20.8 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.) |
