文摘
The mononuclear Co(II) complex, trans-[Co(Pir)2(DMF)2], where Pir is piroxicam, has been prepared in two different ionic liquids and fully characterized. The interaction of the complex with CT-DNA and BSA has been monitored using different analytical methods. The results have indicated that the complex binds to CT-DNA by a groove mode and also a partial insertion of a Pir ligand between the base stacks of DNA. The molecular docking of the complex with DNA has revealed that the complex can fit into the major groove and is stabilized by intermolecular hydrogen bonding and hydrophobic interactions. The results have also shown a moderate binding propensity of the complex to BSA. The molecular modeling has indicated that the binding mode of the complex to BSA is of hydrophobic and hydrogen bond interactions.
