Design and synthesis of potent and selective azaindole-based Rho kinase (ROCK) inhibitors.

Rho kinase plays a pivotal role in several cellular processes such as vasoregulation, making it a suitable target for the treatment of hypertension and related disorders. We discovered a new compound class of Rho kinase (ROCK) inhibitors containing a 7-azaindole hinge-binding scaffold tethered to an aminopyrimidine core. Herein we describe the structure-activity relationships elucidated through biochemical and functional assays.
