- Abstract
To improve the antitumor properties and optimize the pharmaceutical properties including solubility and protein binding of indolin-2-ones, a number of different basic and weakly basic analogues were designed and synthesized. 5-[5-Fluoro-2-oxo-1,2-dihydroindol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3- carboxylic acid (2-diethylaminoethyl)amide (12b or SU11248) has been found to show the best overall profile in terms of potency for the VEGF-R2 and PDGF-Rbeta tyrosine kinase at biochemical and cellular levels, solubility, protein binding, and bioavailability. 12b is currently in phase I clinical trials for the treatment of cancers.
