Abstract Fifteen N4-benzyl-substituted isatin-3-thiosemicarbazones 5a–o were synthesized and evaluated for their urease and glycation inhibitory potential. Lemna aequinocitalis growth and Artemia salina assays were also done to determine their phytotoxic and toxic effects. All compounds are potent inhibitors of the urease enzyme, displaying inhibition [half maximal inhibitory concentration (IC50)=1
摘要 合成了 15 种 N4-苄基取代的靛红-3-缩氨基硫脲 5a-o,并评估了它们的脲酶和糖基化抑制潜力。还进行了 Lemna aequinocitalis 生长和卤虫试验以确定它们的植物毒性和毒性作用。所有化合物都是脲酶的有效抑制剂,显示抑制作用 [半数最大抑制浓度 (IC50)=1.08±0.12–11.23±0.19 μm] 优于参考抑制剂硫脲 (IC50=22.3±1.12 μm)。化合物 5c、5d、5h、5j、k 是有效的抗糖化剂,显示出比参考抑制剂芦丁更好的糖化抑制活性(IC50 值 209.87±0.37–231.70±6.71 vs. 294.5±1.5 μm)。在植物毒性试验中,11 种缩氨基硫脲 5a-d、5g、5h、5j-l、5n,o 是有活性的,表明对 L. 的生长有 5-100% 的抑制作用。aequinocitalis 在最高测试浓度(1000 或 500 微克/毫升)。在盐水虾
