Quinine‐Derived Imidazolidin‐2‐imine Ligands: Synthesis, Coordination Chemistry, and Application in Catalytic Transfer Hydrogenation

Synthesis, Spectroscopic Characterization, Antibacterial and Short Term in vitro Cytotoxicity Studies of Copper(II) Complexes of Novel Tridentate N,N,S Donor Ligand 2-Benzoylpyridine-N(4),N(4)-(N,N-diethyl-N-methylamine-2,2'-diyl)thiosemicarbazone

“…The molar conductivities of 10 -3 M DMF solutions of the complexes indicate they are non-conductors with values less than 20 Ω -1 mol -1 cm -1 . The partial elemental analysis data and conductance measurements are consistent with the general formulation [CuLX] where X= Cl (1), NO 3 (2), SO 4 (3), N 3 (4), SCN (5). For the compound 3, the elemental analysis data matches with the stoichiometry containing two molecules of water of crystallization/lattice water.…”

“…The third donor atom, present in the ring of heterocyclic thiosemicarbazones (N in the case of the pyridine ring, O in the case of pyridine N-oxide) makes them potentially tridentate. The combination of heterocyclic ring with azomethine moiety exerts potential biological and catalytic activities [5]. The activity is found to be highly pronounced where the thiosemicarbazone gets attached through the 2-position of the heterocyclic system and the activity diminishes when the point of attachment is shifted further to 3 or 4-positions presumably due to lower coordination ability.…”

Synthesis of moxifloxacin–Au (III) and Ag (I) metal complexes and their biological activities

“…It is clear from the recent literature that the trend towards the preparation of the drug-metal complexes has huge applications and will continue to occur in future medicinal applications (Ott 2009;Gasser et al 2011;Maftei et al 2015;Simon et al 2005). However, the newly prepared drug-metal complexes have been more significant in present days, because they show good biological activity and these metal complexes find a role in detecting diseases (Neda et al 2000;Filimon et al 2010). The drug-metal complexes were also used to control the growth of pathogens and parasites which are harmful to humans.…”

Synthesis, characterization and biological studies of a novel Cu(II) Schiff base complex

“…Further, quinolines as well as their derivatives are also a class of ligands exhibiting a wide range of biological applications. In fact, some quinoline based Schiff base ligands and their Cu(II) complexes have been reported to show interesting pharmacological properties [29][30][31][32][33][34]. Our perusal on the literature has indicated that no attention has been paid to explore the biological properties of 4-(diethylamino)-3-quinolin-3ylimino-methyl-2-phenol and its Cu(II) complexes.…”
