Design and Optimization of Selective Protein Kinase C θ (PKCθ) Inhibitors for the Treatment of Autoimmune Diseases
摘要:
Protein kinase C theta (PKC theta) has a central role in T cell activation and survival; however, the dependency of T cell responses to the inhibition of this enzyme appears to be dictated by the nature of the antigen and by the inflammatory environment. Studies in PKC theta-deficient mice have demonstrated that while antiviral responses are PKC theta-independent, T cell responses associated with autoimmune diseases are PKC theta-dependent. Thus, potent and selective inhibition of PKC theta is expected to block autoimmune T cell responses without compromising antiviral immunity. Herein, we describe the development of potent and selective PKC theta inhibitors, which show exceptional potency in cells and in vivo. By use of a structure based rational design approach, a 1000-fold improvement in potency and 76-fold improvement in selectivity over closely related PKC isoforms such as PKC delta were obtained from the initial HTS hit, together with a big improvement in lipophilic efficiency (LiPE).
The present invention relates to compounds useful as inhibitors of protein kinase. The invention also provides pharmaceutically acceptable compositions comprising said compounds and methods of using the compositions in the treatment of various disease, conditions, or disorders. The invention also provides processes for preparing compounds of the inventions.
