A series of ureas derivedfromphenethylamines were synthesized and evaluated for human carbonic anhydrase (hCA) I and II, acetylcholinesterase (AChE), and butyrylcholinesterase (BChE) enzyme inhibitoryactivities and antioxidant properties. The ureas were synthesized from the reactions of substituted phenethylamines with N,N‐dimethylcarbamoyl chloride; then, the synthesized compounds were converted
合成了一系列源自苯乙胺的尿素,并评估了人类碳酸酐酶 (hCA) I 和 II、乙酰胆碱酯酶 (AChE) 和丁酰胆碱酯酶 (BChE) 的酶抑制活性和抗氧化特性。脲由取代苯乙胺与 N,N-二甲基氨基甲酰氯反应合成;然后,合成的化合物通过 O-去甲基化转化为相应的酚类衍生物。hCA I 和 II 被新合成的化合物有效抑制,hCA I 的 Ki 值范围为 0.307–0.432 nM,hCA II 的 Ki 值范围为 0.149–0.278 nM。另一方面,这些化合物的 AChE 和 BChE 的 Ki 参数分别在 0.129–0.434 和 0.095–0.207 nM 的范围内确定。酚醛脲也显示出良好的抗氧化活性。
