Discovery of Selective, Orally Bioavailable Pyrazolopyridine Inhibitors of Protein Kinase Cθ (PKCθ) That Ameliorate Symptoms of Experimental Autoimmune Encephalomyelitis
摘要:
PKC theta plays an important role in T cell biology and is a validated target for a number of disease states. A series of potent and selective PKC theta inhibitors were designed and synthesized starting from a HTS hit compound. Cell activity, while initially a challenge to achieve, was built into the series by transforming the nitrile unit of the scaffold into a primary amine, the latter predicted to form a new hydrogen bond to Asp508 near the entrance of the ATP binding site of PKC theta. Significant improvements in physiochemical parameters were observed on introduction of an oxetane group proximal to a primary amine leading to compound 22, which demonstrated a reduction of symptoms in a mouse model of multiple sclerosis.

The present invention provides compounds that are gamma secretase modulators and are therefore useful for the treatment of diseases treatable by modulation of gamma secretase such as Alzheimer's disease. Also provided are pharmaceutical compositions containing such compounds and processes for preparing such compounds.
