Product Introduction

Bioactivity
Description
DREADD agonist 21 is a potent agonist of human muscarinic acetylcholine M3 receptors (EC50=1.7 nM).
Targets&IC50
M1 (human):(pki)5.97 , M4 (human):5.44(pki), H1 receptor:(ki)6 nM, M3Dq (human):1.7 nM (EC50), 5-HT2A receptor:66 nM(ki), α1A-adrenoceptor:280 nM(ki), M4Di (human):6.75(pki), 5-HT2C receptor:170 nM(ki), M1Dq (human):7.2(pki)
In vitro
DREADD agonist 21 is a highly selective and potent agonist for muscarinic DREADDs (pEC50 for hM1Dq=6.54 and that for hM4Di=7.77 in pERK assays)[2]. DREADD agonist 21 potently activates hM3Dq in Chinese hamster ovary (CHO) cells transfected cells in vitro (pEC50: 8.48±0.05) and it also potently activates hM1Dq, hM3Dq, and hM4Di. DREADD agonist 21 does not activate human M3 receptor (hM3). DREADD agonist 21 displays high binding affinities to 5HT2A and 5HT2C serotonin receptor, α1A adrenergic receptor, and H1 histamine receptor with Ki values of 66, 170, 280, and 6 nM, respectively[1]. In addition to being inactive at hM3, DREADD agonist 21, a potent full agonist of hM3Dq (EC50=1.7 nM), is only 3.5-fold selective for hM3Dq over H1, 40-fold selective over 5HT2A, 100-fold selective over 5HT2C, and 165-fold selective over α1A. DREADD agonist 21 binds to hM1, hM4, hM1Dq and hM4Di receptors (pKis of 5.97, 5.44, 7.20, and 6.75, respectively).
In vivo
DREADD agonist 21 has excellent pharmacokinetic properties, bioavailability and brain penetrability. DREADD agonist 21 (0.3, 1.0, and 3.0 mg/kg; i.p.) activates neuronal hM3Dq in mice. DREADD agonist 21 (0.1, 1, and 10 mg/kg; i.p.) shows 95.1% plasma protein binding and 95% brain protein bounding in mice[2].

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:
TargetMol | Animal experimentsFor 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 DMSOTargetMol | 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 DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
