Abstract:
:Two closely related scaffolds were identified through an uHTS campaign as desirable starting points for the development of Rho-Kinase (ROCK) inhibitors. Here, we describe our hit-to-lead evaluation process which culminated in the rapid discovery of potent leads such as 22 which successfully demonstrated an early in vivo proof of concept for anti-hypertensive activity.
