Abstract
Two new copper thiosemicarbazone complexes with an ONNS quadridentate system were synthesized and evaluated for anticancer activity on cisplatin-resistant neuroblastoma cells. Among these two copper complexes, the substituted 8-hydroxyquinoline-2-carboxaldehyde-4,4-dimethyl-3-thiosemicarbazide (CuHQDMTS) exhibited stronger cell growth inhibition activity than the unsubstituted copper 8-hydroxyquinoline-2-carboxaldehyde thiosemicarbazide complex (CuHQTS). Both CuHQTS and CuHQDMTS showed dose-dependent cell growth inhibition, cell cycle arrest and apoptosis induction activities on the SK-N-DZ neuroblastoma cells. Increased expression of p53 protein molecules was detected in the SK-N-DZ cells treated with CuHQTS. The data obtained in this study suggest that CuHQDMTS and CuHQTS hold potential as new, effective drugs for treatment of refractory neuroblastoma in children.Entities:
