  Synthesis, anticancer activity and photophysical properties of novel substituted 2-oxo-2H-chromenylpyrazolecarboxylates

  摘要：

  2-Oxo-2H-chromenylpyrazolecarboxylates (8a-h and 12a-zb) have been synthesized by [3 + 2] cycloaddition of 2H-chromenophenylhydrazones (7a-h and 11a-w) with diethyl/dimethylbut-2-ynedioates. Phenylchromeno[4,3-c]pyrazol-4(1H)-ones (13i-n) were prepared from corresponding phenylhydrazones (7a-h) with catalytic amount of piperidine in presence of pyridine as a solvent at 100 degrees C. All the synthesized compounds (8a-h, 12a-zb and 13a-n) were screened for anticancer activity against three human cancer cell lines such as prostate (DU-145), lung adenocarcinoma (A549), and cervical (HeLa) by standard MTT assay method. Further, photophysical properties (UV and fluorescence) for these compounds were discussed. (C) 2013 Elsevier Masson SAS. All rights reserved.
