Product Introduction
Huperzine B AI Summary
Huperzine B exhibits significant inhibitory activity against various forms of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), demonstrating a range of bioactivities in different experimental setups. It has a Ki value of 794.0 nM against fetal bovine serum (FBS) AChE and a Ki value of 334.0 nM against Torpedo californica AChE. In vitro, it inhibits human recombinant AChE with an IC50 of 30.0 nM and BuChE with an IC50 of 227,000.0 nM, showing moderate selectivity towards AChE with a selectivity index of 11.8-12. Huperzine B also reverses vecuronium-induced neuromuscular block in guinea pig hemi-diaphragm with an EC50 of 19.0 nM and in vivo in chloralose-anesthetized cats with an ED50 of 0.08 µmol/kg, achieving a maximum reversal of 156.0%. Additionally, it induces a decrease in mean arterial pressure (MAP) by 17.0% and heart rate (HR) by 8.0%, while increasing the response to vagal stimulation by 102.0% in anesthetized cats..

Calculator
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, and a total of 10 animals are to be administered, using a formulation of 
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 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 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 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.
