GtoPdb Ligand ID: 8856

Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Compound 8a was designed as a small-molecule inhibitor of the lymphoid-specific non-receptor tyrosine phosphatase, LYP (PTPN22) [1]. PTPN22 directly dephosphorylates several kinase enzymes, effecting negative regulation of T-cell receptor (TCR) signaling [3], and is implicated in autoimmune diseases [4].

Immunopharmacology Comments
PTPN22 inhibitors are being used to study the role of this enzyme in immune system function and regulation, particularly since a gain-of-function mutation in the enzyme (R628W; exhibits elevated phosphatase activity and more effective T cell signalling inhibition capacity than the wild-type enzyme [2]) correlates with susceptibility to several human autoimmune diseases.
