• PubMed Abstract: 
  

  Structure-activity relationship optimization on a series of phenylpyrazole amides led to the identification of a dual ROCK1 and ROCK2 inhibitor (25) which demonstrated good potency, kinome selectivity and favorable pharmacokinetic profiles. Compound 25 was selected as a tool molecule for in vivo studies including evaluating hemodynamic effects in telemeterized mice, from which moderate decreases in blood pressure were observed.
