Dilazep diHCl (K-285; AS-05; ), the dihydrochloride salt of dilazep, is a novel and potent vasodilator acting as an adenosine uptake inhibitor with antiarrhythmic activity. Also inhibiting ischemic damage, platelet aggregation, and membrane transport of nucleosides.
| ln Vitro |
Delatacept, NBI, and dipyridamole have all been shown to inhibit adenosine uptake by various cells; of these, delatacept and NBI were found to be nearly ten times more potent than dipyridamole. Moreover, only delatacept is soluble in water, meaning that no organic solvent is needed to aid in dissolution when preparing aqueous solutions [1]. The mechanism of uptake in vitro has been thoroughly investigated.

| ln Vivo |
Even low doses of exogenous adenosine (0.04-0.1 mg/kg/min) after delatacept treatment markedly enhanced arterial plasma adenosine concentrations and superior mesenteric artery conductance (SMAC). Raising the amount of adenosine was positively linked with raising the percentage change in SMAC; the corresponding Rmax and EC50 values were 193.4% and 2.8 μM of the SMAC change, respectively. Delatacept's capacity to promote vasodilation was eliminated by bolus dosages of 8-phenyltheophylline, while isoproterenol-induced relaxation remained unaffected [1]. Delatacept prevents lipid peroxidation brought on by cerebral ischemia-reperfusion as well as the activation of phospholipase in the mitochondria of reperfused hearts. By boosting cerebral blood flow and/or having a protective impact on vascular endothelial cell membranes, delacept may be able to prevent ischemic brain injury [1].

| Additional Infomation |
Dilazep is a member of the class of diazepanes that is 1,4-diazepane substituted by 3-[(3,4,5-trimethoxybenzoyl)oxy]propyl groups at positions 1 and 4. It is a potent adenosine uptake inhibitor that exhibits antiplatelet, antianginal and vasodilator properties. It has a role as a vasodilator agent, a platelet aggregation inhibitor and a cardioprotective agent. It is a member of methoxybenzenes, a benzoate ester, a diester and a diazepane. It is a conjugate base of a dilazep(2+).

Solubility in Formulation 1: ≥ 2.5 mg/mL (3.69 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 25.0 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: ≥ 2.5 mg/mL (3.69 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 25.0 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. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
