Anticancer Potential of Palladium(II) Complexes With Schiff Bases Derived from 4-Aminoacetophenone Against Melanoma In Vitro

Anticancer Res. 2019 Dec;39(12):6693-6699. doi: 10.21873/anticanres.13884.

Abstract

Background/aim: Melanoma represents a big challenge for clinical treatment. Besides being the most aggressive and the deadliest form of skin cancer, it is often refractory to commonly used anticancer drugs. Hence, developing new anti-cancer agents is crucial to improve refractory melanoma treatment. Studies using palladium(II) complexes have reported antitumor effects on cancer cells. In this study, we aimed to determine the cytotoxic effect of three novel synthesized Pd(II) complexes with Schiff bases derived from 4-aminoacetophenone on the MDA-MB-435 melanoma cell line.

Materials and methods: Cells were treated with ligand and Pd(II) complexes. Cell viability, morphology and death induction upon treatment were examined.

Results: Novel synthesized Pd(II) complexes led to decreased viability of cells. They also induced morphological alterations and cell death, mainly in the C3 complex.

Conclusion: The novel synthesized complexes have a significant cytotoxic effect on cell line MDA-MB-435, especially C3 and can be considered as an antitumor agent for further studies.

Keywords: Antitumor effect; cell death; cell viability; metal complexes; skin cancer.
