    We describe the design, synthesis and SAR of a series of 2-aminobenzothiazole inhibitors of Rho Kinase (ROCK) 1 and 2 which were optimized to low nanomolar potencies using structure-based design. Protein Kinase A was used as a surrogate protein structure to guide compound design. A subset of these molecules also showed robust activity in a myosin phosphatase cell based assay and in a mechanical hyperalgesia in vivo pain model.
