Synonyms: compound 11 [PMID: 28139931] | example 5 [WO2015083028] | PF-06651600 | PF06651600
Compound class: Synthetic organic
Comment: Ritlecitinib (PF-06651600) is a potent, orally active, selective covalent inhibitor of Janus kinase 3 (JAK3) , with anti-inflammatory activity in in vivo models . It is example 5 in a Pfizer patent that provides SAR for 343 analogues . There are three crystal structures available for compounds reported in  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.
Ligand Activity Visualisation Charts
These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.✖
