Ultrasonic-assisted synthesis of 1,4-disubstituted 1,2,3-triazoles via various terminal acetylenes and azide and their quorum sensing inhibition
An efficient synthesis of 1,4-disubstituted 1,2,3-triazole derivatives was studied. 1,4-Disubstituted 1,2,3-triazoles containing isoxazole and thymidine structures were synthesized in 84–96% yields starting from various terminal isoxazole ether alkynes and β-thymidine azide derivatives via a 1,3-dispolar cycloaddition using copper acetate, sodium ascorbate as the catalyst under ultrasonic assisted condition. All the target compounds were characterized by HRMS, FT-IR, 1H NMR and 13C NMR spectroscopy. Furthermore, the quorum sensing inhibitory activities of synthesized compounds were evaluated with Chromobacterium violaceum (C. Violaceum CV026) based on their inhibition of violacein production, with compound C10-HSL as a positive control. The compounds 8a, 8c and 8f exhibited considerable levels of inhibitory activity against violacein production, and IC50 values were 217?±?19, 223?±?20 and 42.8?±?4.5?μM, respectively, which highlighted the potential of these compounds as lead structures for further research towards the development of novel QS inhibitors.

Efficient solvent-free synthesis of bis(indolyl)methanes on SiO2 solid support under microwave irradiation
An efficient synthesis of bis(indolyl)methanes was developed. Bis(indolyl)methanes were synthesized starting from various aromatic aldehydes with indole under microwave irradiation and solvent-free conditions (85-98 %). Solid support SiO2 was found to possess favorable catalytic and dispersancy parameters for the condensation reaction. Moreover, novel bis(indolyl)methanes containing an isoxazole ring were synthesized via this method in excellent yields (> 94 %) using 3-substituted isoxazole-5-carbaldehydes and indole.

Efficient synthesis of bis-isoxazole ethers via 1,3-dipolar cycloaddition catalysed by Zn/Zn2+ and their antifungal activities
An efficient method was developed for synthesising isoxazoles. A series of novel bis-isoxazole ether compounds VI, VII and VIII were synthesised starting from different substituted aldehydes (I) via a 1,3-dispolar cycloaddition using Zn/Zn2+ as a catalyst; these were characterised by FT-IR, HRMS, 1H NMR and 13C NMR spectroscopy. In addition, the antimicrobial properties of the synthesised products were investigated. The synthesised compounds exhibited significant antifungal activities in comparison with the standard drugs, fluconazole and itraconazole. It was found that Candida albicans was sensitive to 2-substituted phenyl bis-isoxazole ethers bearing pyridyl.

Design, synthesis and antibacterial activity of novel N-formylhydroxylamine derivatives as PDF inhibitors
A new series of N-formylhydroxylamines 11a-i have been synthesized through a multi-step protocol starting from diethyl malonate. These compounds have been structurally characterized by IR, 1H NMR and HRMS. All the synthesized compounds 11a-i have been screened for antibacterial activities. All the compounds are found to exhibit potent in vitro inhibitory activity against Staphylococcus aureus and relatively weak antibacterial activity against Klebsiella pneumoniae.

Synthesis and preliminary antibacterial evaluation of 2-butyl succinate-based hydroxamate derivatives containing isoxazole rings
Two series of novel 2-butyl succinate-based Hydroxamate derivatives containing isoxazole rings were synthesized, characterized and evaluated for antibacterial activity. The synthesized compounds were found to exhibit weak to moderate inhibitory activity against Staphytlococcus aureu and Klebsiellar pneumonia in vitro. All the compounds synthesized were found to be more effective against Klebsiellar pneumonia compared to Staphytlococcus aureu.

Concise synthesis and antimicrobial activities of new substituted 5-isoxazolpenicillins
The synthesis of a series of new 5-isoxazolpenicillins is described, which were obtained by coupling substituted isoxazoles with 6-APA. Concise large-scale synthesis of 3,5-disubstituted isoxazoles by 1,3-dipolar cycloaddition using copper(I) as catalyst was also investigated. Representative compounds were assayed for antimicrobial activities, showing satisfactory antimicrobial activities against Gram-negative bacteria.
