We designed a series of substituted flavones and aurones as non-competitive H1N1 neuraminidase (NA) inhibitors and anti-influenza agents. The molecular docking studies showed that the designed flavones and aurones occupied 150-cavity and 430-cavity of H1N1-NA. We then synthesized these compounds and evaluated these for cytotoxicity, reduction in H1N1 virus yield, H1N1-NA inhibition and kinetics of

potent inhibitors among the three series were nitro substitutedcompounds 1g, 2g and 3g with Ki values of approximately 6.18x10(-8) M, 4.8x10(-7) M and 7.85x10(-7) M for cathepsin B and Ki values of approximately 2.8x10(-7) M, 31.8x10(-6) M and 33.7x10(-6) M for cathepsin H, respectively. The relationship between chalcone, flavanones and flavone structures interpreted by docking studies on cathepsin

An efficient and clean synthesis of 1,3-diaryl-2-propenones has been carried out by Claisen Schmidt condensation reaction of aryl methyl ketones with a series of aromatic aldehydes at room temperature in the presence of the catalyst silicotungstic acid (STA). This method provides an ecofriendly, chemoselective, efficient and green synthesis of 1,3-diaryl-2-propenones in excellent yields.
A nanosilica-supported dual acidic ionicliquid on the basis of 1-methyl-3-(4-sulfobutyl)imidazolium hydrogen sulfate was synthesized and used as an efficient, green, non-corrosive, non-toxic, heterogeneous, and reusable catalyst for the synthesis of some new and known substituted flavanones. The synthesis was done by the condensation of 2'-hydroxyacetophenone with different aldehydes and the subsequent
