 |  | [Uses] 
 Tiron is a superoxide scavenger used in the study and examination of oxide electronics. Maintains the ability to remove or destroy magnetic moments which may occur on the surface of such materials.
 |  | [Definition] 
 ChEBI: Tiron is an organic molecular entity.
 |  | [in vivo] 
 
 Tiron (200 mg/kg, oral gavage) ameliorates oxidative stress and inflammation in a murine model of airway remodeling[2].Tiron (300 mg/kg, i.p., daily for two weeks) alleviated apoptosis of the left ventricular cardiomyocytes in STZ-induced diabetic mice[3].
 
 | Animal Model: | BALB/c mice challenged with Ovalbumin (OVA) aerosol for 8 weeks[2] |  | Dosage: | 200 mg/kg |  | Administration: | Oral gavage. |  | Result: | Inhibited levels of NOx, IL-13 and TGF-β1, and immunoreactivity of NF-κB. | 
| Animal Model: | STZ-induced diabetic mice[3] |  | Dosage: | 300 mg/kg |  | Administration: | i.p., daily for two weeks. |  | Result: | Reduced the levels of total oxidized proteins and advanced glycation end products (AGEs)-related proteins. Inhibited cardiac myocyte apoptosis.
 Decreased PKCδ localization on plasma membrane.

 |  | [Purification Methods] 
 Recrystallise it from water [Hamaguchi et al. Anal Chim Acta 9 563 1962]. Itisan indicator colour reagent for Fe, Mn, Ti and Mo ions and complexes with Al, Cd, Co, Co, Fe (III), Mn, Pd, UO22+, VO2+ and Zn. [Beilstein 11 IV 630.]
