Synthesis and Biological Evaluation of Novel -Indolinones with Anticancer Activity.

Novel variously substituted thiohydantoin-based -indolinones were prepared using a regio- and diastereoselective synthetic route from 5-arylidene-2-thiohydantoins, isatines, and sarcosine. The obtained molecules were subsequently evaluated in vitro against the cancer cell lines LNCaP, PC3, HCT, and HCT. Several compounds demonstrated a relatively high cytotoxic activity vs.
