| ln Vitro |
In rats, arteries with a significant drop in threshold (the mesenteric resistance artery and the aorta) contract when exposed to (1 nM to 100 μM) with (+)-norfenfluramine[1]. Aortic contraction is induced in tissues of normotensive and hypertensive rats by (+)-Norfenfluramine (1 and 10 μM, 3 min)[1]. Rat hippocampus synaptosomes release 5-HT in a Ca2+-dependent manner when exposed to (0–10 μM)-Norfenfluramine for three minutes [2].

| ln Vivo |
In conscious SHAM and DOCA-salt rats, (+)-Norfenfluramine (1-300 μg/kg, iv) generates a pressor response[1]. Rat telencephalon and brainstem 5-HT and 5-HIAA levels are decreased by (+)-Norfenfluramine (2.5 and 5 mg/kg, ip)[3].

| Animal Protocol |
Animal/Disease Models: Conscious SHAM and DOCA-salt rats[1].
Doses: 1-300 μg/kg Route of Administration: intravenous (iv) injection (iv), given in a cumulative fashion at 6-min intervals. Experimental Results: Induced pressor response in conscious SHAM and DOCA-salt rats. (change in mean arterial blood pressure at 300 μg/kg, mm Hg, SHAM vehicle=36, SHAM ketanserin=7, DOCA=51, DOCA ketanserin=19). |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (12.30 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 (12.30 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 saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. View More
Solubility in Formulation 3: 2.5 mg/mL (12.30 mM) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. |

*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
