Amsulostat

**Semantic type:** Pharmacologic Substance

**Definition:** An orally available, small-molecule, irreversible inhibitor of all lysyl oxidases (LOX) family members, with potential antifibrotic activity. Upon oral administration, amsulostat targets, binds to and inhibits the activity of all enzymes in the LOX family. This prevents the post-translational oxidative deamination of lysine residues on target proteins, including collagen and elastin, and reduces the formation of deaminated lysine (allysine), the formation of inter- and intramolecular cross-linkages and may prevent remodeling of the extracellular matrix (ECM), thereby reducing fibrotic tissue formation in certain chronic fibrotic diseases. LOX is often upregulated in fibrotic tissue and plays a key role in fibrosis.
