Discovery of (R)-1-(3-((2-Chloro-4-(((2-hydroxy-2-(8-hydroxy-2-oxo-1,2-dihydroquinolin-5-yl)ethyl)amino)methyl)-5-methoxyphenyl)amino)-3-oxopropyl)piperidin-4-yl [1,1′-Biphenyl]-2-ylcarbamate (TD-5959, GSK961081, Batefenterol): First-in-Class Dual Pharmacology Multivalent Muscarinic Antagonist and β2 Agonist (MABA) for the Treatment of Chronic Obstructive Pulmonary Disease (COPD)
摘要:
Through application of our multivalent approach to drug discovery we previously reported the first discovery of dual pharmacology MABA bronchodilators, exemplified by 1. Herein we describe the subsequent lead optimization of both muscarinic antagonist and beta(2) agonist activities, through modification of the linker motif, to achieve 24 h duration of action in a guinea pig bronchoprotection model. Concomitantly we targeted high lung selectivities, low systemic exposures and identified crystalline forms suitable for inhalation devices. This article culminates with the discovery of our first clinical candidate 12f (TD-5959, GSK961081, batefenterol). In a phase 2b trial, batefenterol produced statistical and clinically significant differences compared to placebo and numerically greater improvements in the primary end point of trough FEV1 compared to salmeterol after 4 weeks of dosing in patients with moderate to severe chronic obstructive pulmonary disease (COPD).

Reduction of nitroarenes with low solubility in EtOH-H2O to anilines easily occurs in a Fe-NH(4)Cl-acetone-H(2)O system, and treatment of the same nitroarenes with Fe-NH(4)Cl-EtOH-H(2)O hardly furnished the corresponding products. Under the reaction condition, the reducible or hydrolysable groups are not affected.
