Product Introduction

Bioactivity

Description	L-(R,S)-Tetrahydropalmatine (Rotundine) is extracted from Corydalis yanhusuo W. T. Wang.
In vitro	Rotundine displays a higher affinity to dopamine D1 than D2 receptor with Ki of 124 nM and 388 nM, respectively, while the IC50 values are 166 nM (D1) and 1.47 μM (D2), respectively. Rotundine exhibits a weak inhibitory activity against dopamine D3 with IC50 of 3.25 μM. Rotundine also potently inhibits 5-HT1A with IC50 of 374 nM and Ki of 340 nM. In addition to the antagonism of postsynaptic dopamine receptors, inhibition of presynaptic autoreceptors by Rotundine leads to increased dopamine release, which is probably attributed to lower affinity of Rotundine for D2 receptors. Along with dopamine receptors, Rotundine can interact with a number of other receptor types, including α-1 adrenergic receptors, at which it functions as an antagonist, and γ-aminobutyric acid receptors, at which it facilitates γ-aminobutyric acid binding through positive allosteric effects.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
