The synthesis of 6-(tert-butyl)-8-fluoro-2,3-dimethylquinoline carbonate derivatives and their antifungal activity against Pyricularia oryzae

Long Cheng, Ruirui Zhang, Hongke Wu, Xinghai Liu, Tianming Xu

Frontiers of Chemical Science and Engineering 2019, Volume 13, Issue 2,   Pages 369-376 doi: 10.1007/s11705-018-1734-7

Abstract: A series of novel 6-( -butyl)-8-fluoro-2,3-dimethylquinoline carbonate derivatives were designed and synthesized. Bioassay results showed that some of them exhibited good activity against ( ). It was found that the compound (benzyl (6-( -butyl)-8-fluoro-2,3- dimethylquinolin-4-yl) carbonate) possessed good activity against whatever protective activity (10 mg·L ) or curative activity (25 mg·L ), which was better than that of control tebufloquin. In addition, the frontier molecular orbit results revealed that the compound held higher activity against when the total energy was low and the ClogP was high, which may provide useful information for further design novel fungicides.

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 5,   Pages 905-911 doi: 10.1007/s11783-015-0786-x

Abstract: nano-silicon (Si) and common Si on lead (Pb) toxicity, uptake, translocation, and accumulation in the riceThe results showed that Si application alleviated the toxic effects of Pb on rice growth.Pb concentrations in rice grains treated with common Si and nano-Si decreased by 21.3%–40.9% and 38.6%growth, preventing Pb transfer from rice roots to aboveground parts, and blocking Pb accumulation inrice grains, especially in high-Pb-accumulating rice cultivars and in heavily Pb-polluted soils.
