“…After the addition of H 2 SO 4 , the mixture was shaken for 30 minutes to obtain a pale pink solid. To eliminate H 2 SO 4 , the solid was washed with absolute ethanol (25). Afterwards, in a 50-mL round-bottomed flask, 5.00 g (0.036 moles) choline chloride was dissolved in 10 mL water, and then the mixture was stirred.…”

Background: The antimicrobial resistance of pathogenic bacteria has emerged as a major health problem in recent years. Extensive research has been conducted to find new antimicrobial agents. Objectives: The aim of this study was to examine the antibacterial activities of benzohydrazide derivatives. Methods: Manganese hydrogen sulfate choline chloride was applied in a simple method for synthesizing benzohydrazide derivatives. Antibacterial activities of the derivatives were assessed against Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, Bacillus subtilis, diphtheroids, Salmonella enterica, Serratia marcescens, Pseudomonas aeruginosa, and Klebsiella pneumoniae. The structure of the synthesized compounds was determined employing 1 H/13C NMR and Fourier-transform infrared (FT-IR) spectroscopy. The reactions were carried out in choline chloride dissolved in water at room temperature. Results: The results of this study showed that benzohydrazide derivatives had very desired antibacterial activities against the assessed bacteria. Conclusions: Further investigations are required to assess the safety and efficacy of benzohydrazide derivatives as antibacterial agents in vivo and in vitro.

A three-component Mannich-type reaction of aromatic aldehydes, ketones, and amines was catalyzed by a novel choline-based acidic ionic liquid. The proposed catalyst was a Lewis-Brønsted dual acid catalyst as well as water-tolerant. The β-amino carbonyl compounds were obtained at room temperature in reasonable to good yields ranging from 63 to 98%. After the reaction, the catalyst could be recycled and reused for 5 times without obvious decrease of the yield. Further, the catalyst was environment-friendly with a significant biodegradation rate.
