L748337

Catalog No. T22905Cas No. 244192-94-7

L748337 is a competitive and potent β3-adrenoceptor antagonist that inhibits the action of β3-, β2-, and β1-adrenoceptors, activates MAPK signaling, promotes phosphorylation of Erk1/2, and inhibits the protective effects of CL316243, and is used in the study of disorders caused by abnormalities of the β3-adrenoceptors.

Product Introduction

Bioactivity

Description	L748337 is a competitive and potent β3-adrenoceptor antagonist that inhibits the action of β3-, β2-, and β1-adrenoceptors, activates MAPK signaling, promotes phosphorylation of Erk1/2, and inhibits the protective effects of CL316243, and is used in the study of disorders caused by abnormalities of the β3-adrenoceptors.
In vitro	The β3-adrenergic receptor selective antagonist L748337 (100nM) partially antagonized the relaxation induced by (-)-isoprenaline in cav-1KO arteries, but did not antagonize the relaxation in WT arteries[1].
In vivo	L748337 (5 mg/kg) exhibits anti-cancer effects in male C57BL/6 J mice (8 weeks of age) bearing syngeneic B16F10 cells[1].
Alias	L-748,337

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
