  New coumarin derivatives: Design, synthesis and use as inhibitors of hMAO

  摘要：

  A series new 2H-chromene-3-carboxamides (4a-4i) and S-2H-chromene-3-carbothioates (5j-5t) were synthesized and evaluated as monoamine oxidase A and B inhibitors. Among them, compound 5k (IC50=0.21μM, IC50 iproniazid=7.65μM) showed the most activity and higher MAO-B selectivity (189.2-fold vs 1-fold) with respect to the MAO-A isoform. The need to clarify at a 3D level some important molecular aspects of discussed SAR, we undertaked a number of docking simulations to better assess. The steric effect was analyzed interms of both posing and scoring by investigating the nature of the binding interactions. The docking results of active compound 5k with hMAO-B complex indicated that conserved residue ILE 199 was important for ligand binding via Sigma-Pi interaction.

  A series new 2H-chromene-3-carboxamide derivatives 4a-4t were synthesized and evaluated as monoamine oxidase A and B (MAO-A and MAO-B) inhibitors. Among them, compound 4d (IC50 = 0.93 μM, IC(50 iproniazid) = 7.80 μM) showed the most activity and higher MAO-B selectivity (64.5-fold vs. 1-fold) with respect to the MAO-A isoform. The active compound 4d was also docked into the hMAO-B complex structure active site to determine the probable binding model. The results indicated that conserved residue CYSA 172 was important for ligand binding via hydrogen bond interaction, Pi-Pi interaction was found between the benzene-ring of compound 4d and residue ILEA 199.
