Tiron Chemical Properties,Usage,Production

Chemical Properties

light tan powder

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.

Uses

In determination of trace metals.

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.]
