Synthesis and Antibacterial Evaluation of N-phenylacetamide Derivatives Containing 4-Arylthiazole Moieties

A series of new N-phenylacetamide derivatives containing 4-arylthiazole moieties was designed and synthesized by introducing the thiazole moiety into the amide scaffold. The structures of the target compounds were confirmed by 1H-NMR, 13C-NMR and HRMS. Their in vitro antibacterial activities were evaluated against three kinds of bacteria-Xanthomonas oryzae pv. Oryzae (Xoo), Xanthomonas axonopodis pv. Citri (Xac) and X.oryzae pv. oryzicola (Xoc)-showing promising results. The minimum 50% effective concentration (EC50) value of N-(4-((4-(4-fluoro-phenyl)thiazol-2-yl)amino)phenyl)acetamide (A1) is 156.7 μM, which is superior to bismerthiazol (230.5 μM) and thiodiazole copper (545.2 μM). A scanning electron microscopy (SEM) investigation has confirmed that compound A1 could cause cell membrane rupture of Xoo. In addition, the nematicidal activity of the compounds against Meloidogyne incognita (M. incognita) was also tested, and compound A23 displayed excellent nematicidal activity, with mortality of 100% and 53.2% at 500 μg/mL and 100 μg/mL after 24 h of treatment, respectively. The preliminary structure-activity relationship (SAR) studies of these compounds are also briefly described. These results demonstrated that phenylacetamide derivatives may be considered as potential leads in the design of antibacterial agents.

Thiazole ring-containing amide compounds as well as preparation method and application thereof

The invention discloses thiazole ring-containing amide compounds as well as a preparation method and application thereof, and belongs to the field of chemical technologies and pesticides. According to the present invention, p-phenylenediamine is adopted as a raw material to synthesize a series of the thiazole ring-containing amide compounds, and the synthesized thiazole ring-containing amide compounds have good inhibition effects on Xanthomonas oryzae pv.Oryza (Xoo), Xanthomonas oryzae pv.Oryzcola (Xoc) and Xanthomonas axonophora pv.Citri (Xac) in agricultural diseases and insect pests, and can be used for preparing the anti-plant bacterium agent.
