Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: The structure for lepzacitinib was obtained from proposed INN list 129 (August 2023) where it is described as a Janus kinase inhibitor and anti-inflammatory agent. It is one of the compounds claimed in patent WO2019090158A1 [1]. Aclaris have three JAK inhibitors in their development pipeline, two of which are in clinical assessment: ATI-1777 (a soft inhibitor for topical applications such as atopic dermatitis), and ATI-2138 (a dual ITK/JAK3) inhibitor for T cell-mediated autoimmune diseases. Lepzacitinib is most likely ATI-1777.
