Description: Macrophage migration inhibitory factor (MIF) inhibitor
Chemical Name: 4,5-Dihydro-3-(4-hydroxyphenyl)-5-isoxazoleacetic acid methyl ester
Purity: ≥98% (HPLC)
Biological Activity for ISO 1
ISO 1 is a macrophage migration inhibitory factor (MIF) inhibitor (IC50 = 7 μM); inhibits MIF tautomerase activity in vitro and in vivo. Protective against mouse models of streptozotocin-induced diabetes mellitus; blocks anti-inflammatory response following LPS exposure and increases survival. Inhibits airway remodeling in a mouse model of chronic asthma. Cell permeable; orally bioavailable.
Compound Libraries for ISO 1
ISO 1 is also offered as part of the Tocriscreen 2.0 Max and Tocriscreen Antiviral Library. Find out more about compound libraries available from Tocris.

Rheumatoid Arthritis Poster
Rheumatoid arthritis (RA) is a chronic destructive inflammatory autoimmune disease that results from a breakdown in immune tolerance, for reasons that are as yet unknown. This poster summarizes the pathology of RA and the inflammatory processes involved, as well as describing some of the epigenetic modifications associated with the disease and the potential for targeting these changes in the discovery of new treatments.
