“…Catecholase enzyme catalyzes the conversion of 3,5-di-tert-butylcatechol to 3,5-di-tert-butylquinone [7,8] while phenoxazinone synthase catalyzes the formation of 2-aminophenoxazine-3-one (APX) from 2-aminophenol (OAPH) [9].…”

A novel aminoketooxime ligand and its mononuclear Cu(II) and Mn(II) complexes were synthesized. The structures of the synthesized compounds were illuminated by elemental analysis, inductively coupled plasma optical emission spectrometry, the Fourier transform infrared, 1 H-and 13 C-NMR, UV-Vis, magnetic susceptibility and conductivity measurements. According to the characterization studies ligand to metal ratio was found to be 2:1 with strong binding affinity of the ligand to the metal ions. In addition, complexes have been tested for their catecholase and phenoxazinone synthase-like activities. Kinetic studies were also carried out yielding Vmax, kcat and KM values of both complexes for catecholase and phenoxazinone synthase-like activities. Both complexes efficiently catalyzed the reactions of the enzymes they mimicked.

New ruthenium(II) complexes with formulae [RuCl(CO)(PPh 3 ) 2 L 1 ] and [RuCl(CO)(PPh 3 ) 2 L 2 ] (L 1 = S-allyl-4-methoxy benzylidene hydrazine carbodithioate, L 2 = S-allyl-1-naphthylidene hydrazine carbodithioate) have been synthesized and characterized by elemental analysis, Fourier transform infrared (FTIR), nuclear magnetic resonance (NMR), UV-Vis, electrospray ionization (ESI)-mass spectral studies. Both the Schiff base ligands are coordinated to ruthenium through azomethine nitrogen (C=N) and thiolato sulfur donor atoms in the thiolate form. On the basis of spectral data obtained, an octahedral structure has been assigned to all the new complexes, satisfied by coordination of donor atoms N and S. The stability of complexes in solution was determined by molar conductivity measurements. The interaction of the two complexes with calf thymus (CT) DNA was investigated by fluorescence spectroscopic and viscometric methods. Bovine serum albumin (BSA) protein was examined by fluorescence spectroscopic methods. These techniques indicate that the two metal complexes bind to DNA via intercalation mode and BSA bind with static interaction. Catecholase and phosphatase like activities promoted by these two complexes under physiological conditions have been studied. In vitro anticancer activities have been demonstrated by 3,4,5-dimethylthiazolyl-2-2,5-diphenyltetrazolium bromide (MTT) assay, acridine orange/ethidium bromide (AO/EB) and diamidino-2-phenylindole (DAPI) staining against HeLa cancer cell line.
