Synthesis and in vitro anticancer activity of 2,4-azolidinedione-acetic acids derivatives

The synthesis and evaluation of anticancer activity of 2,4-thia(imida)zolidinedione-3- and 5-acetic acids amides were described. The structures of compounds were determined by IR, H-1 NMR, and MS analysis. In vitro anticancer activity of these compounds has been tested in National Cancer Institute (NCI) and the relationships between structure and anticancer activity are discussed. Among 2,4-azolidinedione-acetic acids derivatives 2-[5-(4-chlorobenzylidene)-2,4-dioxo-imidazolidin-3-yl]-N-(2-trifluoromethyl-phenyl)-acetamide (Ic) was superior to other related compounds in terms of high selectivity for the leukemia CCRF-CEM (log GI(50) = -6.06), HL-60(TB) (log GI(50) = -6.53), MOLT-4 (log GI(50) = -6.52) and SR (log GI(50) -6.51) cell lines.
