| Description: | The inhibitor potency of BA-1049 (racemic mixture) and Fasudil (Calbiochem) were compared by fluorescent polarization assays performed using a Biomek 2000 robotic workstation (Beckman Instruments, Palo Alto, Calif.) in a 96-well plate format. The assay was performed utilizing the IMAP® ROCK I and ROCK II kits (Molecular Devices Corp.) as follows. Substrate (synthetic peptide capable of being phosphorylated by ROCK I or ROCK II: KEAKEKRQEQIAKRRRLSSLRASTSKSGGSQK) (SEQ ID NO:1) and ATP concentrations used were 200 nM and 10 μM, respectively, while the enzyme (ROCK I, ROCK II recombinantly-produced kinase domain) concentration was 3.96×10^−3 units per well. The substrate, enzyme, and ATP dilutions were made with reaction buffer provided by the vendor. The test compound was diluted in 1-:10 DMSO-ethanol (vol/vol). The various components were added into black, clear bottom 96-well plates in a final volume of 20 μL per well. After the enzyme reaction (60 min at 23° C.), 60 μL of the binding solution (IMA kits provided by vendor) was added per well and incubated an additional 30 min in the dark at 23° C. Fluorescent polarization of the reaction mixtures was then measured on the Analyst® HT instrument (Molecular Devices Corp.). |
