Aberrant signaling of phosphoinositide 3-kinase δ (PI3Kδ) has been implicated in numerous pathologies including hematological malignancies and rheumatoid arthritis. Described in this manuscript are the discovery, optimization, and in vivo evaluation of a novel series of pyridine-containing PI3Kδ inhibitors. This work led to the discovery of 35, a highly(More)
Inhibition of phosphoinositide 3-kinase δ (PI3Kδ) is an appealing target for several hematological malignancies and inflammatory diseases. Herein, we describe the discovery and optimization of a series of propeller shaped PI3Kδ inhibitors comprising a novel triaminopyrimidine hinge binder. Combinations of electronic and structural strategies were employed(More)
Bronchodilators are a central therapy for symptom relief in respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma, with inhaled β 2-adrenoceptor agonists and anticholinergics being the primary treatments available. The present studies evaluated the in vivo pharmacology of(More)
Inhaled long-acting β(2)-adrenoceptor agonists (LABA) that act as bronchodilators and the oral anti-inflammatory phosphodiesterase 4 (PDE4) inhibitor roflumilast are both approved therapies for chronic obstructive pulmonary disease (COPD). Here we describe the activity of a novel, inhaled, bifunctional, small molecule(More)
