Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Petesicatib is the INN for a cathepsin S inhibitor. The structure (and CAS registry number) submitted to the WHO match PubChem CID 59543597, and this ties the INN together with the research code RO5459072 assigned by Hoffman-La Roche to their cathepsin S inhibitor [2-3]. This same chemical structure is claimed in Hoffmann-La Roche patent WO2010121918A1, where it is example 238 [1].
