Synthesis and biological evaluation of oxindoles and benzimidazolinones derivatives

The synthesis of new oxindoles and benzimidazolinones derivatives bearing a sugar residue on the aromatic nitrogen is described. The presence of the glycoside moiety should enhance the solubility of these heterocyclic compounds and/or improve the interaction with the active site of the biological targets. The inhibitory activities of these new compounds toward five kinases were examined: KDR (VEGFR-2), FGFR-1, PDGFR-β, EGFR and Tie 2. Furthermore, the antibacterial activities of the prepared compounds were tested against two Gram-positive bacteria Bacillus cereus and Streptomyces chartreusis, a Gram-negative bacterium Escherichia coli and a yeast Candida albicans.
