Synthesis, characterization, theoretical studies, ADMET and drug-Likeness analysis: Electrochemical and biological activities of metal complexes of 3-(2-hydroxybenzoyl)-2H-chromen-2-one

Coordination compounds of 3-(2-hydroxybenzoyl)-2H-chromen-2-one were synthesized by the reaction of Cu(II), Co(II) and Zn(II) salts in molar ratio 1:1 in basic media. The compounds formed were characterized using infrared, Uv-vis spectrophotometric analyses, mass spectrometry, elemental analyses and NMR spectroscopy. It was concluded that 3-(2-hydroxybenzoyl)-2H-chromen-2-one coordinated as a mono ligand for all the complexes; it also coordinated via the two carbonyl moieties. The electrochemical behavior of these compounds was determined by cyclic voltammetry. The synthesized compounds were screened for their antimicrobial and antioxidant activities. The complexes exhibited good antimicrobial activity against Staphylococcus aureus (ATCC 25923) and good antioxidant activity. Parameters drug-likeness and ADME properties are calculated.
