Product Introduction

Bioactivity

Description	(R)-Terazosin is an active R-enantiomer of Terazosin and a potent antagonist of α1-adrenoceptor [(α1a, α1b, and α1d-adrenoceptor] with Ki values of 6.51 nM, 1.01 nM, and 1.97 nM, respectively).
Targets&IC50	α1A-adrenoceptor:6.51 nM (Ki), α1B-adrenoceptor:1.01 nM (Ki), α1D-adrenoceptor:1.97 nM (Ki)
In vitro	(R)-Terazosin exhibits low affinity for α2a, α2B, and α2c-adrenoceptors (Ki of 3.85 μM, 0.33 μM, and 0.37 μM, respectively). It may serve as a useful probe for exploring the functional roles of adrenoceptor subtypes in various tissues.
In vivo	(R)-Terazosin demonstrates antagonism at rat atrial α2B receptor (pEC30: 5.69) and at rat vas deferens α1A and α2A receptors (pA2: 7.5 and 5.31, respectively).

In Vivo Formulation Calculator (Clear solution)

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

For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments

A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent

DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。

Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO TargetMol | reagent

(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.

Preparation method for in vivo formula: Take 50 μL DMSO TargetMol | reagent

main solution, add 300 μLPEG300 TargetMol | reagent

mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O TargetMol | reagent

mix well and clarify
