Abstract
The ability of Monensic acid A (MonH∙H2O) and its neutral metal complexes [M(Mon)2(H2O)2]with ions of Mg2+, Ca2+, Mn2+, Co2+, Ni2+ and Zn2+ to decrease viability and proliferation of primary cell cultures, originating from a chemically induced transplantable liver tumour of Zajdela in rats, and bone marrow cells from the same tumour-bearers, was evaluated. Experimental data revealed that manganese(II) and nickel(II) complexes of Monensin A are relatively more selective against the tumour as compared to the healthy bone marrow cells.
