Uses

They are admirably suited for studies on orientation of the furan nucleus, both by absolute and relative methods. In addition they make beta-substituted furans more accessible.

Design and synthesis of heteroaromatic-based benzenesulfonamide derivatives as potent inhibitors of H5N1 influenza A virus

Influenza A virus is an enveloped negative single-stranded RNA virus that causes febrile respiratory infection and represents a clinically challenging threat to human health and even lives worldwide. Even more alarming is the emergence of highly pathogenic avian influenza (HPAI) strains such as H5N1, which possess much higher mortality rate (60%) than seasonal influenza strains in human infection. In this study, a novel series of heteroaromatic-based benzenesulfonamide derivatives were identified as M2 proton channel inhibitors. A systematic investigation of the structure-activity relationships and a molecular docking study demonstrated that the sulfonamide moiety and 2,5-dimethyl-substituted thiophene as the core structure played significant roles in the anti-influenza activity. Among the derivatives, compound 11k exhibited excellent antiviral activity against H5N1 virus with an EC50 value of 0.47 μM and selectivity index of 119.9, which are comparable to those of the reference drug amantadine.

Design, synthesis and antifungal activity of novel furancarboxamide derivatives

Twenty-seven novel furancarboxamide derivatives with a diphenyl ether moiety were synthesized and evaluated for their antifungal activity against Rhizoctonia solani, Botrytis cirerea, Valsa Mali and Sphaceloma ampelimum. Antifungal bioassay results indicated that most compounds had good or excellent fungicidal activities for R. solani and S. ampelimum at 20 mg L-1. Among synthesized compounds, compound 18e showed a greater inhibitory effect against S. ampelimum, with half maximal effective concentration (EC50) values of 0.020 mg L-1. This strong activity rivals currently used commercial fungicides, such as Boscalid and Carbendazim, and has great potential as a lead compound for future development of novel fungicides.

Design, synthesis and in vitro antibacterial/antifungal evaluation of novel 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7(1-piperazinyl)quinoline-3-carboxylic acid derivatives

A series of 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7(1-piperazinyl)quinoline-3-carboxylic acid (norfloxacin) derivatives were prepared according to the principle of combinating bioactive substructures and tested for their activities against five plant pathogenic bacteria and three fungi in vitro. The preliminary bioassays indicated that almost all synthesized target compounds retained the antibacterial activities of norfloxacin and had some antifungal activities as carboxylic acid amide compounds. The activities of compounds 1 and 22 against Xanthomonas oryzae were better than norfloxacin and all tested compounds had better antibacterial activities as compared to the agricultural streptomycin sulfate (a commercial bactericide) against X. oryzae, Xanthomonas axonopodis and Erwinia aroideae. Additionally, compounds 2 and 20 displayed good antifungal activities against Rhizoctonia solani and their inhibition of growth reached 83% and 94% respectively at the concentration of 200 mg/L.
