Lumeras, Wenceslao published the artcileDesign, Synthesis, and Structure-Activity Relationships of Aminopyridine N-Oxides, a Novel Scaffold for the Potent and Selective Inhibition of p38 Mitogen Activated Protein Kinase, Synthetic Route of 209919-30-2, the publication is Journal of Medicinal Chemistry (2009), 52(17), 5531-5545, database is CAplus and MEDLINE.
A novel series of aminopyridine N-oxides, e.g. I, were designed, synthesized, and tested for their ability to inhibit p38α MAP kinase. Some of these compounds showed a significant reduction in the LPS-induced TNFα production in human whole blood. Structure-activity relationship studies revealed that N-oxide oxygen was essential for activity and was probably a determinant factor for a marked selectivity against other related kinases. Compound I was identified as a potent and selective p38α inhibitor with an appropriate balance between potency and pharmacokinetics. In vivo efficacy of I was demonstrated in reducing TNFα levels in an acute murine model of inflammation (ED50 = 1 mg/kg in LPS-induced TNFα production when dosed orally 1.5 h prior to LPS administration). The oral efficacy of I was further demonstrated in a chronic model of adjuvant arthritis in rats with established disease when administered orally (ED50 = 4.5 mg/kg).
