成功制备了纳米级CdS,对其进行了充分表征,并将其用作高效可重复使用的光催化剂,用于通过缩合反应合成吡咯并[3,4- c ]喹诺酮和吡咯并[2,1 - a ]异喹啉-8-羧酸酯衍生物的ñ,ñ -dimethylanilines或烷基2-(3,4-二氢异喹啉-2(1 H ^) -基)乙酸酯与马来酰亚胺通过一个C-H活化在室温下良性和生态友好的条件下的方法,而无需使用任何溶剂,并且可见光照射下的氧化剂。此外,所制备的光催化剂已成功地用于N,N的缩合反应。-二甲基苯胺与烷基丁-2-炔基或苯基乙炔的合成,首次用于合成新的1,2-二氢喹啉-3,4-二羧酸酯和芳基1,2-二氢喹啉衍生物。使用这种方法,通过使用可再生能源可见光辐照,可以在良性条件下以良好的收率和较短的反应时间获得所有有利的产物。该催化剂易于回收并重复使用几次,而不会损失其活性。
target for many diseases, however, up to now, there is no AC2-selective agonist reported. In this research, docking-based virtual screening with the combination of cell-based biological assays have been performed for discovering novel potent and selective AC2 agonists. Virtual screening disclosed a novel hit compound 8 as an AC2 agonist with EC50 value of 8.10 μM on recombinant human hAC2 + HEK293 cells
Different maleimide derivatives were synthesized and assayed for their in vitro activity on the soil inhabiting, plant-parasitic nematode Meloidogyne incognita, also known as root-knot nematode. The compounds maleimide, N-ethylmaleimide, N-isopropylmaleimide, and N-isobutylmaleimide showed the strongest nematicidal activity on the second stage juveniles of the root-knot nematode with EC50/72h values of 2.6 +/- 1.3, 5.1 +/- 3.4, 16.2 +/- 5.4, and 19.0 +/- 9.0 mg/L, respectively. We also determined the nematicidal activity of copper sulfate, finding an EC50 value of 48.6 +/- 29.8 mg/L. When maleimide at 1 mg/L was tested in combination with copper sulfate at SO mg/L, we observed 100% mortality of the nematodes. We performed a GC-MS metabolomics analysis after treating nematodes with maleimide at 8 mg/L for 24 h. This analysis revealed altered fatty acids and diglyceride metabolites such as oleic acid, palmitic acid, and 1-monopalmitin. Our results suggest that maleimide may be used as a new interesting building block for developing new nematicides in combination with copper salts.
