“…All the MAO-B inhibitory activities were retrieved from the in vitro measurement of the enzymatic activity of human recombinant MAO isoforms in BTI insect cells infected with baculovirus. 5,15 All the molecules under study shared a common structural motif of 6-methylcoumarin while compounds 5-8 possessed a bromine substituent on the C8 position of coumarin ring. Bearing this in mind, candidate molecules were evaluated within two distinct groups (C8-halogenated and C8-nonsubstituted) and for each subclass, a prototype docked pose in the binding pocket of MAO-B was explored (figures 1-3).…”

Quantum chemical analysis of potential anti-Parkinson agents

Monoamine oxidases (MAOs) are amine oxidoreductase falvoenzymes that belong to the integral proteins of the outer mitochondrial membrane. MAO exists in two distinct isoforms; MAO-A and MAO-B. Inhibition of MAO-A and MAO-B is important for developing antidepressant and antiparkinson agents, respectively. In the light of the above explanations, detailed structure binding relationship studies on the intermolecular binding components of MAO-B complexes may unravel the way toward developing novel anti-Parkinson agents. In the present contribution, intermolecular binding pattern for a series of experimentally validated 3-arylcoumarin MAO-B inhibitors (1-9) have been elucidated via molecular docking and density functional theory (DFT) calculations. Intermolecular binding energy components could not be analyzed by docking and due to this limitation, quantum mechanical (QM) calculations including functional B3LYP in association with split valence basis set (Def2-SVP) were applied to estimate the ligand-residue binding energies in the MAO-B active site. Moreover; results were interpreted in terms of calculated polarization effects that were induced by individual amino acids of the MAO-B active site. The results of the present study provide an approach to pharmacophore-based modification within the 3-arylcoumarin scaffold for potent MAO-B inhibitors.

[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Taking in account the versatility of the coumarin moiety one can thoroughly modify it to best serve one purposes. In this work, our group fused two other classes of natural products onto the coumarin skeleton, the chalcones (figure 1 -A) and the resveratrol derivatives ( figure 1 -B).…”

Coumarins are a class of heterocyclic compounds present in a significant quantity in several plants. The simplest coumarin, a benzene ring fused with a pyran-2-one heterocycle, was first discovered in the 19 th century and since then, due to the synthetic accessibility and the biological properties of its derivatives, has been playing an important role in the Medicinal Chemistry field. In fact, coumarins have been previously described as anticancer, antiviral, anti-inflammatory, antimicrobial, enzymatic inhibitory and antioxidant agents.Another two interesting compounds found widely in nature are resveratrol derivatives and chalcones. Both families of compounds are known for having remarkable antioxidant activity, cardio-and neuroprotective effects, among other relevant biological properties. Therefore, we devised several synthetic strategies to incorporate these natural products in one compound, combining their potential as promising agents for the treatment of several illnesses.In our group, we have already synthesised multiple novel compounds incorporating into the coumarin scaffold the resveratrol or chalcones moieties with remarkable activities towards different pharmacological targets. In this work, we continue exploiting this strategy by incorporating different linkers at coumarin position 3, thus giving us a wide range of possibilities for new compounds.
