Synthesis and biological evaluation of diversely substituted indolin-2-ones

The synthesis of indolin-2-one derivatives substituted in the 3-position by an aminomethylene group bearing either an ornithine or a lysine residue is described. The inhibitory activities of these compounds toward a panel of eight kinases were examined. 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.
