  Synthesis and Biological Evaluation of Urea Derivatives as Highly Potent and Selective Rho Kinase Inhibitors

  摘要：

  RhoA and its downstream effector ROCK mediate stress fiber formation and cell contraction through their effects on the phosphorylation of myosin light chain (MLC). Inhibition of the RhoA/ROCK pathway has proven to be a promising strategy for several indications such as cardiovascular disease, glaucoma, and inflammatory disease. In 2010, our group reported urea-based ROCK inhibitors as potential antiglaucoma agents. These compounds showed potent IC50 values in enzymatic and cell-based assays and significant intraocular pressure (IOP)-lowering effects in rats (similar to 7 mmHg).(22) To develop more advanced ROCK inhibitors targeting various potential applications (such as myocardial infarction, erectile dysfunction, multiple sclerosis, etc.) in addition to glaucoma, a thorough SAR for this urea-based scaffold was studied. The detailed optimization process, counter-screening, and in vitro and in vivo DMPK studies are discussed. Potent and selective ROCK inhibitors with various in vivo pharmacokinetic properties were discovered.

  Rho kinase (ROCK) is a promising drug target for the treatment of many diseases including hypertension, multiple sclerosis, cancer, and glaucoma. The structure-activity relationships (SAR) around a series of tetrahydroisoquinolines were evaluated utilizing biochemical and cell-based assays to measure ROCK inhibition. These novel ROCK inhibitors possess high potency, high selectivity, and appropriate pharmacokinetic properties for glaucoma applications. The lead compound, 35, had subnanomolar potency in enzyme ROCK-II assays as well as excellent cell-based potency (IC(50) = 51 nM). In a kinase panel profiling, 35 had an off-target hit rate of only 1.6% against 442 kinases. Pharmacology studies showed that compound 35 was efficacious in reducing intraocular pressure (IOP) in rats with reasonably long duration of action. These results suggest that compound 35 may serve as a promising agent for further development in the treatment of glaucoma.
