Abstract:
:Inhibition of Rho kinase (ROCK) is an attractive strategy for the treatment of diseases such as hypertension, glaucoma, and cancer. Here we report chroman-3-amides as highly potent ROCK inhibitors with sufficient kinase selectivity, excellent cell activity, good microsomal stability, and desirable pharmacokinetic properties for study as potential therapeutic agents.
