Structurally characterized mononuclear Mn(II) complex: Functional model for catecholase and phenoxazinone synthase activities

Structure–function correlation of mononuclear nonheme copper(ii) compounds based on a ligand backbone effect and phenoxazinone synthase activity

“…Various bioinspired models have been studied owing to the availability of literature reports on the structural and functional properties of PHS. 23,28–35 A tetranuclear cubane-like Cu( ii ) core was first reported by Chaudhuri and co-workers that could catalyze the oxidation of H 2 AP to APX in the presence of molecular oxygen. 28 A few more tetranuclear centres were later reported as the possible mimics of PHS.…”

“…31 In addition, several mononuclear compounds were reported to mimic PHS property. In this respect, not only Cu 32 but other metals like Mn, 33 Fe, 34 and Co 35 have been used to prepare mononuclear mimics of PHS.…”

Mononuclear copper(ii) Schiff base complexes as effective models for phenoxazinone synthase

“…During the past few years, a variety of complexes have been studied as bio-inspired models of phenoxazinone synthase-like activity. 9–20 For instance, Chaudhuri et al reported the characterization of a cuboidal tetracopper( ii )-radical complex and its PHS activity using OAP as a substrate. 9 Later, Ghosh et al employed another tetranuclear complex for learning its PHS activity.…”

“…16 One such latest study on PHS activity has been performed by Ali et al using a binary Cu( ii ) complex with a tridentate ONO hydrazone ligand. 16 a Similar to copper complexes, other first-row transition metal complexes, such as Mn, 17 Fe, 18 and Co, 19 were also proved as models for PHS mimics.…”

Towards potent Covid-19 spike protein inhibitors and catecholase activity agents: Synthesis, ADME-Tox analysis and molecular docking of new 1,2,4- triazole-based molecules

“…A number of copper complexes have shown to promote the oxidation activity as mononuclear catalysts [32,33]. And a number of non-copper complexes are also found to show a similar kind of activity [34,35]. In this sense, N-heterocyclic derivatives have provided a very useful chelating class selected in the unit assembly leading to the coordination framework for various transition metals such as pyrazole, pyridine and imidazole [36][37][38][39][40][41].…”
