L-Hyoscyamine
🥰Excellent
Catalog No. T0962Cas No. 101-31-5
Alias Hyoscyamine, Daturine
L-Hyoscyamine (Daturine) functions as a non-selective, competitive antagonist of muscarinic receptors, thereby inhibiting the parasympathetic activities of acetylcholine on the salivary, bronchial, and sweat glands, as well as the eye, heart, bladder, and gastrointestinal tract. Hyoscyamine is a belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic activity. These inhibitory effects cause a decrease in saliva, bronchial mucus, gastric juices, and sweat. Furthermore, its inhibitory action on smooth muscle prevents bladder contraction and decreases gastrointestinal motility.

| Description | L-Hyoscyamine (Daturine) functions as a non-selective, competitive antagonist of muscarinic receptors, thereby inhibiting the parasympathetic activities of acetylcholine on the salivary, bronchial, and sweat glands, as well as the eye, heart, bladder, and gastrointestinal tract. Hyoscyamine is a belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic activity.

| Targets&IC50 | AChR:7.5 nM |
| In vitro | In vivo studies with conscious rats demonstrated that L-hyoscyamine (20 mg/kg) extended the cyclic period of migrating myoelectric complexes from 17.6 minutes to 29.0 minutes. |
| In vivo | In CHO cells, L-hyoscyamine inhibits excitant-induced cAMP production (EC50: 7.8 nM). In murine cardiac (atrial and ventricular) membranes, S-(-)-hyoscyamine enhances cyclic AMP synthesis stimulated by pilocarpine by 24%. R-(+)-hyoscyamine competes with [3H]NMS for binding to muscarinic acetylcholine receptor subtypes (m1-m5), with pKi values of 8.67, 8.51, 7.46, 8.56, and 8.53, respectively. L-hyoscyamine increases the TPase activity turnover rate from 0.19/min to 2.11/min in steady-state kinetic measurements. |

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.
