Design and synthesis of 7-alkoxy-4-heteroarylamino-3-quinolinecarbonitriles as dual inhibitors of c-Src kinase and nitric oxide synthase
摘要:
Because both c-Src and iNOS are key regulatory enzymes in tumorigenesis, a new series of 4-heteroarylamino-3-quinolinecarbonitriles as potent dual inhibitors of both enzymes were designed, prepared, and evaluated for blocking multiple signaling pathways in cancer therapy. All compounds were evaluated by two related enzyme inhibition assays and an anti-proliferation assay in vitro. The results showed that most compounds could inhibit both enzymes, and several of them showed potent inhibition activity against different cancer cell lines. The best compound 20 (CPU-Y020) showed the IC(50) values of 6.58 and 7.61 mu M toward colon cancer HT-29 and liver cancer HepG2 cell lines. (C) 2008 Elsevier Ltd. All rights reserved.

A simple and efficient method was developed for the synthesis of 4-quinolone-3-carboxylic esters and 4-quinolone-3-carbonitriles under microwave (MW) activation using anilines and acrylates as materials. All reactions demonstrated the benefits of microwave reactions: convenient operation, short reaction time, and good yields.
