Biological Activity for RKI 1447 dihydrochloride

RKI 1447 dihydrochloride is a potent and selective ROCK inhibitor (IC₅₀ values are 6.2 and 14.5 nM for ROCK2 and ROCK1 respectively); suppresses phosphorylation of ROCK substrates MLC-2 and MYPT-1 in human cancer cells, but has no effect on the phosphorylation levels of Akt, MEK, and S6 kinase. Displays anti-invasive and antitumor activities in breast cancer cells.
