Product Introduction

Bioactivity

Description	(S)-Terazosin is an active S-enantiomer of Terazosin and acts as a potent, high-affinity antagonist of α-adrenoceptors [α1a, α1b, and α1d-adrenoceptors] with Ki values of 3.91 nM, 0.79 nM, and 1.16 nM, respectively.
Targets&IC50	α1D-adrenoceptor:1.16 nM (ki), α2A-adrenoceptor: 729 nM (ki), α1B-adrenoceptor:0.79 nM (ki), α2C-adrenoceptor:46.4 nM (ki), α1A-adrenoceptor:ki： 3.91 nM , α2B-adrenoceptor:3.5 nM (ki)
In vitro	(S)-Terazosin and its enantiomers show high and apparently equal affinity for subtypes of α1-adrenoceptors, and showed potent α1-adrenoceptors antagonist in isolated tissues, with the enantiomers approximately equipotent to the racemate at each α1-adrenoceptor subtype. At α2b sites, (R)-Terazosin binds less potently than either the (S)-Terazosin or racemate.
In vivo	(S)-Terazosin shows α2B receptor antagonist at rat atrial(pEC30 of 6.93). (s)-Terazosin shows antagonism of at rat vas deferens α1A and α2A receptor with pA2 values of 8.3 and 6.12, respectively.

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.
