First Discovery of Novel Pyrido[1,2-a]pyrimidinone Mesoionic Compounds as Antibacterial Agents was written by Liu, Dengyue;Zhang, Jian;Zhao, Lei;He, Wengjing;Liu, Zhengjun;Gan, Xiuhai;Song, Baoan. And the article was included in Journal of Agricultural and Food Chemistry in 2019.Safety of 1-(Chloromethyl)-3-methylbenzene This article mentions the following:
Plant bacterial diseases cause tremendous decreases in crop yield and quality, and there is a lack of highly effective and low-risk antibacterial agents. A series of novel pyrido[1,2-a]pyrimidinone mesoionic compounds containing vanillin moieties were synthesized, and the application of these mesoionic compounds as plant antibacterial agents was reported here for the first time. The bioassay results revealed that the mesoionic compounds had good antibacterial activity. Of these compounds, compound (I) showed excellent in vitro activity against Xanthomonas oryzae pv. oryzae, with an EC50 value of 1.1μg/mL, which was substantially better than that of bismerthiazol (92.7μg/mL) and thiodiazole copper (105.4μg/mL). Moreover, greenhouse condition trials indicated that the protective and curative activities of compound I against rice bacterial leaf blight were 75.12% and 72.04%, resp., which were better than those of bismerthiazol (62.24% and 50.83%, resp.) and thiodiazole copper (53.35% and 65.04%, resp.). These results provide a basis for the application of mesoionic vanillin moieties as new antibacterial agents. In the experiment, the researchers used many compounds, for example, 1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9Safety of 1-(Chloromethyl)-3-methylbenzene).
1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Safety of 1-(Chloromethyl)-3-methylbenzene
