5-ARYLMETHYLIDENE-2-IMINOTHIAZOLIDIN-4-ONES IN THE SYNTHESIS OF NOVEL DISPIRO-FUSED OXINDOLEPYRROLIDINEIMINOTHIAZOLIDINONES

Abstract
A novel series of dispiro(indolinonepyrrolidineiminothiazolidinones) were synthesized by 1,3-dipolar cycloaddition of 5-arylmethylidene-2-iminothiazolidin-4-ones and azomethine ylides generated from N-alkylamino acids and isatin derivatives. A number of iminothiazolidinones and dispiro compounds were tested for antiproliferative activity. Seven compounds showed moderate antiproliferative activity at micromolar concentrations against cancer cell lines.
