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.

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]. |
