O-(4-hydroxy-3-iodophenyl)-3-iodo-L-tyrosine Chemical Properties,Usage,Production

Description

3,3''-Diiodo-L-thyronine is a metabolite of thyroid hormone that is also known as T2 or 3,3’-T2. It is derived enzymatically from triiodothyronine isoforms T3 and reverse T3. T2 and its analog 3,5-T2 stimulate the activity of cytochrome c oxidase by blocking inhibition by ATP.

Chemical Properties

Off-White Powder

Uses

Of interest for the early detection and treatment of congenital or drug-induced hypothyroidism in the developing human fetus.

Definition

ChEBI: 3,3'-diiodo-L-thyronine is a 3,3'-diiodothyronine. It has a role as a human metabolite.

IC 50

Human Endogenous Metabolite; COX
