A series of novel quinoline derivatives bearing 5-(aminomethylene) pyrimidine-2,4,6-trione moiety were designed, synthesized, and evaluated for their c-Met kinase inhibitory activities and antiproliferative activities against 5 cancer cell lines (HT-29, H460, MKN-45, A549, and U87MG) in vitro. Most compounds showed moderate to excellent potency, with the most promising analogue 45 (c-Met half-maximal inhibitory concentration [IC50] = 1.15 nM) showing high selectivity versus 5 other tyrosine kinases, VEGFR-2, Flt-3, PDGFR-β, c-Kit, and EGFR. Structure-activity relationship studies indicated that electron-donating groups on the phenyl ring at the 3-position of pyrimidine-2,4,6-trione were required to increase the electron density on the 5-(aminomethylene)pyrimidine-2,4,6-trione moiety.

The reaction of barbituric acid and its N-substituted derivatives and 2-thio analogs with cotarnine forms 5-(4-methoxy-6-methyl-5,6,7,8-tetrahydro-2H-1,3-methylenedioxy-[4,5-g]isoquinolinyl-1)barbituric acids, a new class of zwitter-ions, the structure of which was studied by 1H and 13C NMR spectroscopy and mass spectrometry. The prepared compounds exist in solution as stable intermolecular associates and have a complicated H-bonded structure.
