Coordination susceptibilities of cinnamaldehyde and cuminaldehyde derived Schiff bases towards the fac-[Re(CO)3]+ core: Formation, computational and DNA interaction studies
摘要:
Herein, we explore the coordination behaviours of Schiff bases derived from constituents of essential oils (viz. cinnamaldehyde and cuminaldehyde) and aromatic amines (viz 2-aminophenol and 4-aminoantipyrene) towards the facial tricarbonylrhenium(I) core. The resultant rhenium(I) compounds: (mu-X)(2)[Re(CO)(3)](2) {where X = 2{[3-Phenylprop-2-en-1-ylidene]amino}phenol (ciap) (for 1) or 2-{[4-(propan-2-yl)benzylidene]amino}phenol (cuap) (for 2), fac-[Re(CO)(3)(apy)Cl] (apy = 4-aminoantipyrene) (3) and fac-[Re(CO)(3)(cinap)Cl] (cinap = 1,5-dimethyl-2-phenyl-4-{[3-phenylprop-2-en-1-ylidene]amino}-1,2-dihydro-3H-pyrazol-3-one) (4) were formed. The metal compounds were spectroscopically characterized and structural elucidations were confirmed by single crystal X-ray diffraction. DFT studies were utilized to rationalize the contrasting coordination behaviours of the structural analogues, 1,5-dimethyl-2-phenyl-4-{[4-(propan-2-yl)benzylidene]amino}-1,2-dihydro-3H-pyrazol-3-one (cumap) and cinap in the formation of 3 and 4, respectively. These metal compounds showed affinities towards Calf-Thymus DNA based on UV-Vis DNA binding titrations and molecular docking studies revealed that they are groove binders.
