In the present study, a series of chalcones and their B-aryl analogues were prepared and evaluate as inhibitors of myeloperoxidase (MPO) chlorinating activity, using in vitro and ex vivo assays. Among these, B-thiophenyl chalcone (analogue 9) demonstrated inhibition of in vitro and ex vivo MPO chlorinating activity, exhibiting IC50 value of 0.53 and 19.2 μM, respectively. Potent ex vivo MPO inhibitors 5, 8 and 9 were not toxic to human neutrophils at 50 μM, as well as displayed weak 2,2-diphenyl-1-pycrylhydrazyl radical (DPPH?) and hypochlorous acid (HOCl) scavenger abilities. Docking simulations indicated binding mode of MPO inhibitors, evidencing hydrogen bonds between the amino group at 4′position (ring A) of chalcones with Gln91, Asp94, and Hys95 MPO residues. In this regard, the efficacy and low toxicity promoted aminochalcones and arylic analogues to the rank of hit compounds in the search for new non-steroidal anti-inflammatory compounds.

In the present study we have prepared a series of some chalcones using solvent - free Aldol - condensation by microwave irradiation. The yields of the ketones are more than 60%. The synthesised chalcones were characterized by their analytical, physical and spectral data. The antimicrobial activities of substituted styryl 3-thienyl ketones have been studied using Bauer-Kirby method.
