PIT

Catalog No. T23164Cas No. 56583-49-4
Alias 2,2'-Pyridylisatogen tosylate

PIT (2,2'-Pyridylisatogen tosylate) is a specific, non-competitive antagonist of the Purinergic receptor P2Y1, exhibiting an IC50 of 0.14 μM for human P2Y1. It does not affect nucleotide binding and is useful in studies related to chronic bronchitis and asthma.

Product Introduction

Bioactivity
Description
PIT (2,2'-Pyridylisatogen tosylate) is a specific, non-competitive antagonist of the Purinergic receptor P2Y1, exhibiting an IC50 of 0.14 μM for human P2Y1. It does not affect nucleotide binding and is useful in studies related to chronic bronchitis and asthma.
Targets&IC50
P2Y1:0.14 μM
In vitro
PIT (100 nM-10 μM) diminishes human P2Y1 receptor signaling in a non-competitive and dose-dependent manner and dose-dependently blocks the agonist activity of 2-MeSADP[1]. PIT (0.1-3 μM) increases ATP-responses 2-5 fold. PIT (3-100 μM) inhibits ATP-mediated inward current (IC50 = 13.2 μM). PIT shows affinity to adenosine receptor (pKi = 5.3)[2].
In vivo
In mice with S-bromo-willardiine injection induced tonic and tonicoclonic seizures, intraperitoneal injection of PIT (10 mg/kg) prevents the white matter and the cortical plate lesions against the insult[3].

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
