[Ni^II(3-OMe-salophene)]: A Potent Agent with Antitumor Activity

Abstract

In this study, we investigated the anticancer properties of methoxy-substituted nickel(II)(salophene) derivatives. We demonstrated that the most active complex [NiII(3-OMe-salophene)] is not necrotic in Burkitt-like lymphoma cells (BJAB) and human B-cell precursor cells (Nalm-6). [NiII(3-OMe-salophene)] inhibited proliferation and induced apoptosis in a concentration dependent manner, giving evidence for the involvement of CD95 receptor-mediated, extrinsic pathway. Furthermore, [NiII(3-OMe-salophene)] overcame vincristine drug resistance in BJAB and Nalm-6 cells.
