Janus kinases (JAKs) have a key role in regulating the expression and function of relevant inflammatory cytokines involved in asthma and chronic obstructive pulmonary disease. Herein are described the design, synthesis, and pharmacological evaluation of a series of novel purinone JAK inhibitors with profiles suitable for inhaled administration. Replacement of the imidazopyridine hinge binding motif present in the initial compounds of this series with a pyridone ring resulted in the mitigation of cell cytotoxicity. Further systematic structure-activity relationship (SAR) efforts driven by structural biology studies led to the discovery of pyridone 34, a potent pan-JAK inhibitor with good selectivity, long lung retention time, low oral bioavailability, and proven efficacy in the lipopolysaccharide-induced rat model of airway inflammation by the inhaled route.

Page/Page column 6, (2009/12/07)
There is provided a process for producing an aromatic amine compound having an aralkyloxy or heteroaralkyloxy group, in which an aromatic nitro compound having an aralkyloxy or heteroaralkyloxy group is reacted with hydrogen under mild conditions in accordance with a simple procedure while preventing the removal of aralkyl or heteroaralkyl group and keeping stable the other substituents on the aryl group or heteroaryl group so that the substituent does not take part in the reaction, to selectively reduce only the nitro group. The present invention is directed to a process for producing an aromatic amine compound which comprises reacting an aromatic nitro compound represented by the general formula (1): wherein Ar represents an aryl group or heteroaryl group which may have a substituent, and Z represents a divalent aromatic group which may have a substituent, with hydrogen in the presence of a metal catalyst to obtain an aromatic amine compound represented by the general formula (2): wherein Ar and Z have the meaning as defined above.
