Cancer has been ranked second after cardiovascular diseases. The plant-derived molecules have played an important role for the treatment of cancer. On the account of the reported anticancer activity of quinoline containing biologically active cyanoacetamide moiety, a novel 2-cyano-N-(quinolin-3-yl)acetamide (2) was synthesized using 3-aminoquinoline (1) as strategic starting materials. The corresponding 2-cyano-N-(quinoline-3-yl)-acetamide (2) was obtained in good yield via reaction of 3-aminoquinoline (1) with ethylcyanoacetate in dry toluene. The structure of the newly synthesized compound was confirmed on the basis of elemental analyses, IR, 1H NMR, 13C NMR spectra and X-ray analysis. Compound 2 was found to exert the most powerful effect on Ehrlich ascites carcinoma tumor cells (in vitro) compared with the positive control (doxorubicin) with IC50 of 2.14 μg/mL.

A new and convenientpalladium-catalyzed carbonylative procedure of bromoacetonitrile has been developed. A variety of valuable 2-cyano-N-acetamide and 2-cyanoacetate compounds were obtained in good to excellent yields under mild reaction conditions. Furthermore, this transformation can be carried out under atmospheric pressure and provides an alternative route to 7 drug compounds.

We have developed a series of novel potent ortho-substituted azole derivatives active against kinases VEGFR-1 and VEGFR-2. Both specific and dual ATP-competitive inhibitors of VEGFR-2 were identified. Kinase activity and selectivity could be controlled by varying the arylamido substituents at the azole ring. The most specific molecule (17) displayed > 10-fold selectivity for VEGFR-2 over VEGFR-1. Compound
