ln Vitro |
The IC50 for ROCK2 of the Rho kinase inhibitor H-1152 is 12 nM. With IC50 values of 0.180, 0.360, 0.745, respectively, for CaMKII, PKG, AuroraA, PKA, Src, PKC, MLCK, Abl, EGFR, MKK4, GSK3α, AMPK, and P38α, H-1152 (H-1152P) likewise exhibits reduced inhibitory action [1]. H-1152 has a 1.6 nM Ki for Rho kinase potency and a 0.63, 9.27, and 10.1 μM Ki for PKA, PKC, and MLCK, respectively, for PKA, PKC, and MLCK moderate inhibition. H-1152 (0.1-10 µM) exhibits a strong inhibitory effect on MARCKS phosphorylation in LPA-treated cells, with an IC50 value of 2.5 µM; however, no discernible effect is observed in PDBu-treated cells [2]. H-1152 (0.5-10 μM) does not result in a decrease in neuronal viability. Additionally, H-1152 (1, 5, or 10 μM) did not change the proportion of various neuronal morphologies. Moreover, in BMP4 and LIF cultures, H-1152 (10 μM) lengthens neurites [3].

Enzyme Assay |
Protein kinase assay[2]
To determine the effect of inhibitors on Rho-kinase activity in vitro, inhibitors was added at the indicated concentrations to 50 µL of the assay mixture 50 mm Tris-HCl (pH 7.5), 5 mm MgCl2, 1 mm EDTA, 1 mm EGTA, 1 mm dithiothreitol, 40 µm S6-peptide, various concentrations of [γ-32P]ATP and purified Rho-kinase, which was purified as described previously (Nagumo et al. 2000). The reactions were started by the addition of [γ-32P]ATP and carried out at 30°C for 5 min. The Michaelis–Menten equation was used to calculate the Michaelis constant (Km) and maximal velocity (Vmax) of Rho-kinase. Data were further analyzed with secondary plot to calculate the inhibitory constant (Ki). The effects of Rho-kinase inhibitors on protein kinase A (PKA) and C (PKC) were assayed according to our method with minor modifications (Tokumitsu et al. 1991). The reaction for PKA was carried out at 37°C for 5 min in a 20-µL mixture containing 25 mm Tris-HCl (pH 7.0), 10 mm MgCl2, 2 mm EGTA, 50 µm peptide of cyclic AMP response element binding protein and 10 µm[γ-32P]ATP (150 cpm/pmol). The reaction for PKC was carried out for 5 min in 30 µL of a mixture that contained 50 mm Tris-HCl (pH 7.0), 10 mm MgCl2, 0.5 mm CaCl2, 0.2 mg/mL histone type III-S, 50 µg/mL phosphatidyl serine and 10 µm[γ-32P]ATP (150 cpm/pmol). The effect of Rho-kinase inhibitors on myosin light chain kinase (MLCK) was assayed under the conditions previously described elsewhere (Asano et al. 1989), in 30 µL of a reaction mixture that contained 40 mm HEPES (pH 7.0), 5 mm magnesium acetate, 0.5 mm CaCl2, 0.1% (v/v) Tween-80, 5.3 nm calmodulin, 51 µm myosin light chain peptide, 1.95 nm MLCK and [γ-32P]ATP (150 cpm/pmol)[2].

Cell Assay |
ROCK inhibitor H-1152 was diluted in water and added in an additional 10 μl to cultures 24 h after plating. Water was added to controls. Eighteen hours after the addition of inhibitor, cultures were fixed in 4% paraformaldehyde (1 h at room temperature for peroxidase-linked labeling and 20 min at room temperature for fluorescence labeling). For ArrayScan/Cellomics automated analysis: Cells were plated in a total volume of 50 μl on 384 well plastic plates previously coated with poly-d-lysine/laminin, and cultured in the same medium[3].
To investigate the effects of the protein kinase inhibitors (e.g. H-1152 ), the cells were preincubated with the inhibitors for 15 min and then stimulated with LPA for 1 min or with PDBu for 5 min. At various determination points after the stimulation, 5% (v/v) trichloroacetic acid was added to the cultures and cells were scraped off with a rubber scraper. After sedimentation, the precipitate was washed with acetone containing 6 mm dithiothreitol to remove trichloro-acetic acid and then dried. The dried cell powder was placed in sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS–PAGE) sample buffer containing 125 mm Tris (pH 7.4), 8 m urea, 10% (w/v) sucrose, 0.02% (w/v) bromophenol blue, 4% (w/v) SDS and 2-mercaptoethanol, and the preparation was then extracted by heating at 95°C for 5 min. The samples were passed through a 0.22-µm centrifugal filter (Millipore, Bedford, MA, USA) to remove indissoluble materials. The samples (2.5 × 105 cells) were subjected to SDS–PAGE (7.5%)/western blotting analysis. Proteins in the gel were electrotransferred to a polyvinylidene difluoride membrane. After incubation with 5% (w/v) skimmed milk, the membrane was blotted with pS159-Mar-Ab, followed by anti-mouse IgG antibody. Immunoreactivity was detected by enhanced chemiluminescence-western blotting detection reagents, and its extent was measured by scanning densitometry of the X-ray film using KODAK 1D Image Analysis Software, and expressed as a percentage versus control under each condition[2]. |
