  • Title: Synthesis, characterization and biological evaluation of tertiary sulfonamide derivatives of pyridyl-indole based heteroaryl chalcone as potential carbonic anhydrase IX inhibitors and anticancer agents.

    Abstract:
    In the quest for novel effective carbonic anhydrase inhibitors, some sulfonamide derivatives of pyridyl-indole based chalcone were synthesized and screened in vitro for inhibitory activity against human carbonic anhydrase IX isoform. Among all the synthesized compounds (SC2 -SC11), only three compounds SC3, SC7 and SC10 were found to have better binding affinity as shown by molecular docking and fluorescence binding studies. Further, the enzyme inhibition assay and in vitro anti-tumor evaluation against MCF-7 and HepG-2 cell lines revealed that the compounds SC3, SC7 and SC10 inhibited the CA IX selectively, possessed predominant anti-proliferative potential and significantly induced apoptosis in cancerous cells.
