    • The catalytic domain of RON was cloned downstream of a dimerizing domain from the TPR gene in a homologous fashion to the documented activated TPR-Met gene (Park, M, Dean, M, Cooper, C. S, Schmidt, M, O'Brien, S. J, Blair, D. G, Vande Woude, G. F. Cell 1986, 45, 895, A cellular clone of 293T kidney epithelial cells stably expressing this activated form of RON under a CMV promoter was derived. Cells were treated with compounds dilutions for 150 min and lysate samples from treatment wells were transferred to high binding white polysterene 96 wells plates (Corning, TPR-RON autophosphorylated levels were detected by ELISA using the primary antibodies anti-phospho-Tyrosine (Millipore, 4G10) and a reporter antibody (HRP-cross linked anti-mouse from Sigma, and plates were washed on a plate washer (SkanWasher, Molecular Devises) and subsequently incubated with chemiluminescent substrate solution (ECL, Roche, Luminescence signal was captured on a Polar Star Optima apparatus BMG LabTe

    • To confirm the cell based efficacy of the lead compound on endogenous RON, PC-3 cancer cells or HCT116 cancer cells were treated for 3 h with the indicated doses of compounds. Endogenously expressed RON proteins were immunoprecipitated from cell lysates with anti-RON-beta total (c-20) (Santa cruz biotechnologies) and subjected to immunoblotting analysis using anti-phospho-tyrosine (Millipore, 4G10) or anti-RON-beta total (c-20) (Santa cruz biotechnologies) as indicated. Protein detection was completed using anti-mouse or anti-rabbit horseradish peroxidase (trueblot from e-Bioscience), and subsequently incubated with chemiluminescent substrate solution (ECL plus, Roche). Fluorescent signal was captured on a Storm apparatus (Amersham Biosciences).
