The cell adhesion/recognition protein L1CAM (L1; CD171) has previously been shown to act through integrin, focal adhesion kinase (FAK) and fibroblast growth factor receptor (FGFR) signaling pathways to increase the motility and proliferation of glioblastoma cells in an autocrine/paracrine manner. Here, we investigated the effects of clin. relevant small-mol. inhibitors of the integrin, FAK and FGFR signaling pathways on glioblastoma-derived cells to determine their effectiveness and selectivity for diminishing L1-mediated stimulation. The effects of the FGFR inhibitor PD173074, the FAK inhibitors PF431396 and Y15 and the αvβ3/αvβ5 integrin inhibitor cilengitide were assessed in L1-pos. and L1-neg. variants of the human glioblastoma-derived cell lines T98G and U-118 MG. Their motility and proliferation were quantified using time-lapse microscopy and DNA content/cell cycle analyses, resp. The application of all four inhibitors resulted in reductions in L1-mediated motility and proliferation rates of L1-pos. glioblastoma-derived cells, down to the level of L1-neg. cells when used at nanomolar concentrations, whereas no or much smaller reductions in these rates were obtained in L1-neg. cells. In addition, we found that single inhibitor treatment resulted in maximum effects (i.e., combinations of FAK or integrin inhibitors with the FGFR inhibitor were rarely more effective). These results suggest that FAK may act as a point of convergence between the integrin and FGFR signaling pathways stimulated by L1 in these cells. We here show for the first time that small-mol. inhibitors of FGFR, integrins and FAK effectively and selectively abolish L1-stimulated migration and proliferation of glioblastoma-derived cells. Our results suggest that these inhibitors have the potential to reduce the aggressiveness of high-grade gliomas expressing L1.

The aromatic compound pyrimidine, and its derivatives, are ubiquitous in nature. They are found in nucleic acids, vitamins, amino acids, antibiotics, alkaloids, and a variety of toxins. Pyrimidine derivatives have been used in a wide variety of pharmaceuticals including general anesthetics, anti-epilepsy medication, anti-malaria medication, drugs for treating high blood pressure, and HIV medication.Application In Synthesis of 1-(tert-Butyl)-3-(2-((4-(diethylamino)butyl)amino)-6-(3,5-dimethoxyphenyl)pyrido[2,3-d]pyrimidin-7-yl)urea
