Keywords:
Thiosemicarbazone, Cytotoxicity, Antioxidant, Leukemia, Anticancer drugAbstract
Objective: The present study was aimed to evaluate the cytotoxicity and antioxidant properties of copper complexes of thiosemicarbazone (TSC-Cu) using different in vitro models.
Methods: In vitro MTT assay was carried out against the HL-60 cell line to check the cytotoxic potency of TSC-Cu. In vitro radical scavenging activity of TSC-Cu was evaluated by checking its role in scavenging DPPH, hydroxyl radical and lipid peroxidation.
Results: Among the test molecules studied, TSC-Cu with choride side chain (TSC-Cu-Cl) showed dose and time dependent increased cytotoxic activity on HL-60 cell line compared to TSC-Cu with hydroxyl side chain (TSC-Cu-OH). Further, TSC-Cu-Cl exhibited promising radical scavenging activities against hydroxyl radical, 2,2-diphenyl, 2-picryl hydrazyl (DPPH), and also effectively inhibited lipid peroxidation.
Conclusion: The results of the present investigation confirm that the TSC-Cu-Cl complex can be considered as a novel metal complex with potent anti-oxidant and cytotoxic ability.
