• exceptionally stable duplexes (ΔTm = +44.8 °C) and high selectivity [92]. Six novel 4-aminoantipyrine derived Schiff bases and their metal complexes with Cu(II), Ni(II), Zn(II) ions (conjugates 26–31) were synthesized and characterized and binding of these complexes with ct-DNA were analyzed by electronic

• -free catalysts for SM coupling reactions. Transition metal complexes that have shown a wide range of biological activity are those containing the pyrazolone derivative 4-aminoantipyrine (4-amino-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one, or simply “4-AAP”) [18]. Pyrazoles, in general, are one of the
