Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Ritlecitinib (PF-06651600) is a potent, orally active, selective covalent inhibitor of Janus kinase 3 (JAK3) [5], with anti-inflammatory activity in in vivo models [4]. It is example 5 in a Pfizer patent that provides SAR for 343 analogues [1]. There are three crystal structures available for compounds reported in [5] with JAK3, but not for compound 11 (the PDB identifiers are 5TTV, 5TTU and 5TTS). Pfizer's pipeline webpage indicates that the ritlecitinib program has been discontinued.
