NOVEL QUINOLINE DERIVATIVES AND THEIR APPLICATIONS
-
Paragraph 0207, (2015/11/16)
The invention relates to a series of quinoline derivatives of general formula I, pharmaceutically acceptable salts, hydrates, solvates or prodrugs. Thereof M, R1, R2, X, Y and n are defined as claims. And the compounds of general formula I show potent inhibitory activity against c-Met kinase. The present invention further relates to the uses of the compounds, pharmaceutically acceptable salts and hydrates for the preparation of medicaments for the treatment and/or prevention of diseases caused by abnormal expression of c-Met kinase, especially for treatment and/or prevention of cancer.

Novel quinoline derivatives bearing acyclic semicarbazones were prepared and their chemical structures as well as the relative stereochemistry were confirmed. All the synthesized compounds were evaluated for their c-Met kinase inhibitory activity and their cytotoxicity against the cell lines HT-29, MKN-45, and MDA-MB-231 in vitro. Several potent compounds were further evaluated against A549 cells. Most compounds displayed moderate to excellent activity, and the structure-activity relationship studies identified the most promising compound 35 as a selective c-Met kinase inhibitor (IC50 = 4.3 nM). Compound 35 showed a 3.5- and 18.8-fold increase in cytotoxicity in vitro against HT-29 and A549 cells, respectively, compared to that of foretinib. Poor off-target effects of compound 35 were further confirmed by the antiproliferative activity against the c-Met inhibition less sensitive MDA-MB-231 cell line (IC50 = 0.77 μM). Copyright
