Synthesis, characterization, computational studies, antimicrobial activities and carbonic anhydrase inhibitor effects of 2-hydroxy acetophenone-N-methyl p-toluenesulfonylhydrazone and its Co(II), Pd(II), Pt(II) complexes

2-Hydroxyacetophenone-N-methyl p-toluenesulfonylhydrazone (afptsmh) and its Co(II), Pd(II) and Pt(II) metal complexes were synthesized for the first time and investigated their antibacterial activities and carbonic anhydrase enzyme inhibitor effects. Also 1H and 13C shielding tensors for crystal structure were calculated with GIAO/DFT/B3LYP/6-311++G(d,p) methods in CDCl3.
