The synthesis and evaluation of the anticancer activity of 3′-aryl-5′-arylidene-spiro[3H-indole-3,2′-thiazolidine]-2,4′(1H)-diones and spiro[3H-indole-3,2′-thi-azolidine]-2,4′(1H)-dione-3′-alkanoic acid esters were described. The structure of the compounds was determined by 1H and 13C NMR and their in vitro anticancer activity was tested in the National Cancer Institute. Among the tested compounds, (5′Z)-5′-(benzylidene)-3′-(4-chlorophenyl)spiro[3H-indole-3,2′-thia-zolidine]-2,4′(1H)-dione (IIa) and (5′Z)-3′-(4-chlorophenyl)-5′-[4-(1-methylethyl)-benzylidene]spiro[3H-indole-3,2′-thiazolidine]-2,4′(1H)-dione (IIb) were superior to other related compounds.
