(+)-Norfenfluramine
Based on 1 Customer Validation
(+)-Norfenfluramine a major hepatic metabolite of (+)-fenfluramine, is a selective 5-HT2B receptor agonist (Ki: 11.2 nM). (+)-Norfenfluramine potently stimulates the hydrolysis of inositol phosphates and increases intracellular Ca2+. (+)-Norfenfluramine can be used for the research of primary pulmonary hypertension and valvular heart disease.

(+)-Norfenfluramine (1 nM to 100 μM) contracts arteries with a dramatic decrease in threshold (aorta and mesenteric resistance artery) in rats[1].
(+)-Norfenfluramine (1 and 10 μM, 3 min) induces contraction in aorta from tissues of normotensive and hypertensive rats[1].
(+)-Norfenfluramine (0-10 μM, 3 min) induces 5-HT release from rat hippocampal synaptosomes by Ca2+-dependent way [2].

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: ≥ 2.5 mg/mL (12.30 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (12.30 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
