Benoxathian hydrochloride (10 nM; paraventricular nucleus injection) totally reverses 2.5, 5.0, or 10.0 mg/kg phenylpropanolamine (IP)-induced anorexia in rats [1].
|
| Animal Protocol |
Microinjection of the alpha-1 adrenergic receptor antagonist benoxathian (0, 2.5, 5.0 or 10.0 nmol) into the PVN was found to have no effect on baseline feeding behavior. Microinjection of 10.0 nmol benoxathian into the PVN completely reversed the anorexia induced by 2.5, 5.0 or 10.0 mg/kg PPA (IP), yet did not alter the hypodipsia produced by PPA. These data strongly suggest that PPA anorexia is mediated by an alpha-1 adrenergic satiety mechanism within the PVN.[1]

Adrenergic alpha-Antagonists:
Drugs that bind to but do not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous adrenergic agonists. Adrenergic alpha-antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma.
Antihypertensive Agents: Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS; and VASODILATOR AGENTS. Phenylpropanolamine (PPA) is a phenethylamine anorectic drug that exerts direct agonist effects predominantly on alpha-1 adrenergic receptors, with some alpha-2 adrenergic activity. Direct injections of PPA as well as the alpha-1 agonist 1-phenylephrine into rat paraventricular nucleus (PVN) suppress feeding. In the present study, we evaluate the hypothesis that systemic PPA acts within the PVN on an alpha-1 receptor population to suppress feeding. Accordingly, adult male rats were prepared with a unilateral guide cannula aimed at the PVN. Microinjection of the alpha-1 adrenergic receptor antagonist benoxathian (0, 2.5, 5.0 or 10.0 nmol) into the PVN was found to have no effect on baseline feeding behavior. Microinjection of 10.0 nmol benoxathian into the PVN completely reversed the anorexia induced by 2.5, 5.0 or 10.0 mg/kg PPA (IP), yet did not alter the hypodipsia produced by PPA. These data strongly suggest that PPA anorexia is mediated by an alpha-1 adrenergic satiety mechanism within the PVN.[1] |

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.23 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 (5.23 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. 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.
