POBN BiologicalActivity
| Description | POBN (4-POBN) is a cell permeable, hydrophilic spin trap that can be used to detect free radical adducts[1]. |

|---|
| In Vitro | When POBN (20 mM) and Sodium formate (100 mM) are mixed in the collecting tube with bile in the presence of 2,2′-dipyridyl (DP) (5 mM) and bathocuproinedisulfonic acid disodium salt hydrate (BC) (5 mM), only a minor residual signal of POBN radical adduct is observed[1]. |
|---|
| In Vivo | Electron spin resonance (ESR) spectrum of radical adducts detected in bile of rats 1 h after acute Sodium formate (2 g/kg) and POBN (1.5 g/kg) i.p. administration[1]. Animal Model: Fischer male rats (300-400 g)[1] Dosage: 1.5 g/kg (Pharmacokinetic Analysis) Administration: Injected simultaneously i.p. Result: A strong six-line ESR signal of the POBN radical adduct was detected in the bile of rats after acute sodium formate poisoning. |
