    New 2H-chromene-3-carboxamide derivatives: Design, synthesis and use as inhibitors of hMAO
    摘要:
    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.

    Several 3-carbonyl (1–26), 3-acyl (27–52), and 3-carboxyhydrazido (53–58) coumarins have been synthesized in high yields (72–99%) and tested in vitro for their human monoamine oxidase A and B (hMAO-A and hMAO-B) inhibitory activity. Different substituents on the coumarin nucleus were evaluated for their effect on biological activity and isoform selectivity. Substitution at position C7 of the 3-ethyl

This process installs C–O and C–C bonds via sp3 C–H functionalisation with concomitant generation of two stereocentres. This regioselective radical addition of coumarin system is opposite to that of styrene.

    structure-activity relationship (SAR) study around this scaffold with the aim to discover new selective FXIIa inhibitors with an improved physico-chemical profile. To better understand these SAR, docking experiments were undertaken. For this purpose, we built an original hybrid model of FXIIa. This model has the advantage to gather the best features from the recently published crystal structure of FXIIa

    underscores the need to find new hDPP III inhibitors. In this research, five series of structurally different coumarin derivatives were studied to provide a relationship between their inhibitory profile toward hDPP III combining an in vitro assay with an in silico molecular modeling study. The experimental results showed that 26 of the 40 tested compounds exhibited hDPP III inhibitory activity at a concentration
