Abstract
A series of novel thioxothiazolidin-4-one derivatives 5(a–g) were synthesized by the coupling of different amines containing aliphatic, substituted aromatic, and heterocyclic moieties, such as oxadiazol, pyrazole, isoxazole, and piperazine with 2-(5-(4-chlorophenyl)furan-2-yl)methylene)-4-oxo-2-thioxothiazolidin-3-yl)acetic acid. All compounds were characterized by 1H NMR, LCMS, FTIR and elemental analysis. In this study, we investigated the possibility that these novel thioxothiazolidin-4-one derivatives 5(a–g) inhibits tumor growth and tumor induced angiogenesis using mouse Ehrlich Ascites Tumor (EAT) as a model system. Our results demonstrated that the compounds significantly reduced ascites tumor volume, cell number, and increased the life span of EAT-bearing mice. In addition, the compounds manifested strong antiangiogenic effects and suppressed tumor induced endothelial proliferation in the mice peritoneum. From our findings, it is noted that the derivatives 5(a–e) may be possible candidates for anticancer therapy with the ability to inhibit tumor angiogenesis and tumor cell proliferation.
