New bimetallic dicyanidoargentate(I)-based coordination compounds: Synthesis, characterization, biological activities and DNA-BSA binding affinities

PubMedID: 28029508Four compounds -two (2 and 3) completely new- of composition [Ni(edbea)Ag3(CN)5] (1), [Cu(edbea)Ag2(CN)4]·H2O (2), [Cd(edbea)Ag3(CN)5]·H2O (3) and [Cd(edbea)2] [Ag(CN)2]2·H2O (4) {edbea; 2,2'-(ethylenedioxy)bis (ethylamine)}, were synthesized and characterized using elemental, FT-IR, X-Ray (4), thermal, variable temperature magnetic measurement (1 and 2) and biological techniques. The DNA/BSA binding affinities of 2 and 3 were evaluated by UV–Vis spectrophotometric titrations, ethidium bromide exchange experiments and electrophoretic mobility measurements. Compounds 1 and 4 have previously been characterized and shown to reduce the proliferation and migration of tumor cells. For the sake of clarity, 1 precise mechanism of action on microbial organisms and temperature magnetic measurement were determined. The crystallographic analyses showed that 4 was built up of [Cd(edbea)2]II cations and [Ag2(CN)4]II anions. Complexes demonstrated a remarkable antibacterial (1–4), antifungal (1–4) and antiproliferative activities (2 and 3) to ten human bacterial pathogens, four plant pathogenic fungi or three tumor cells (HeLa, HT29, and C6), respectively. Therefore, our results strongly confirm that cell proliferation, cell morphology, Bcl-2, P53 changes and apoptosis can be related to the pharmacological effects of the complexes as suitable candidate for clinical trials. © 2016 Elsevier B.V.2011/32 CM 2515 TBAG-112T696The authors thank the Scientific and Technical Research Council of Turkey (TUBİTAK, Grant TBAG-112T696 ; COST Action CM 2515 ) and the Gaziosmanpaşa University Research Foundation (Grant 2011/32 ) for financial support.
