Synthesis, spectral characterization, crystal structure and catalytic activity of a novel dioxomolybdenum Schiff base complex containing 4-aminobenzhydrazone ligand: A combined experimental and theoretical study

Synthesis of an amantadine-based novel Schiff base and its transition metal complexes as potential ALP, α-amylase, and α-glucosidase inhibitors

“…Schiff bases have a signicant role as chelating ligands, as these can easily form stable colored complexes with transition metals when stabilizing, and highly supportive groups like -OH are present close to the imine (-HC]N-) group. 1,2 In recent years, the coordination modes of Schiff base ligands to transition metal ions have been studied comprehensively in the pharmaceutical industry. 3 Several substituted heterocyclic moieties in coordination with transition metal ions have shown improved pharmacological and physio-chemical properties.…”

Catalytic activity of a new dioxidomolybdenum(vi) complex with a bipodal N2O-donor ligand in sulfur compound oxidation

“…This result becomes the complex [(MoO 2 ) 2 (BPA) 2 (μ-O)] competitive with literature reports, showing some potential for sulfide oxidation. 22,28,74–79…”

“…This result becomes the complex [(MoO 2 ) 2 (BPA) 2 (m-O)] competitive with literature reports, showing some potential for sulfide oxidation. 22,28,[74][75][76][77][78][79] The last substrate oxidized was dibenzothiophene (DBT). The DBT molecule is very important in the oxidation studies of ODS applications.…”

“…78 The oxidation of thioanisole with H 2 O 2 as an oxidant, catalyzed by molybdenum complex coordinated by a tridentate (ONO) Schiff base ligand derived from isoniazid led to a yield of 91% after 15 min in refluxing ethanol. 78 Our results showed that the conversion of thioanisole was 91% after 1 hour at room temperature and the selectivity to obtain sulfoxide was 56%, using acetonitrile as solvent. The oxidation of diphenyl sulfide and dibenzothiophene catalyzed by a binuclear complex was evaluated 22 and the authors found selectivities in sulfoxide of 30 and 20%, respectively at higher temperature (B80 1C).…”

Metal Complexes with Schiff Bases: Data Collection and Recent Studies on Biological Activities

“…Some SBs derivatives have demonstrated α-glucosidase inhibition and antiglycation activity [ 19 , 20 ], whereas other derivatives were synthesized and used as fluorescent sensors for the diabetic biomarker beta-hydroxybutyrate (β-HB) [ 21 ]. Metal complexes of different metals with SBs have demonstrated a myriad of activities [ 22 , 23 ], and catalytic applications [ 24 ] in which metals are represented by Mo [ 25 ], Cu [ 26 , 27 , 28 ], Zr [ 29 , 30 , 31 ], Pd [ 32 ], Cu [ 33 ], Ni [ 34 ], Ru [ 35 ], Mn [ 36 ], Zn [ 37 , 38 ] and W [ 39 ]. Several studies have been carried out on the transmetalation of Zn-SB complexes with other metal ions [ 40 ] for various purposes, such as the detection of Cu 2+ ions in aqueous solution [ 41 ] and the inhibition of acid-induced steel corrosion [ 42 ].…”
