New reversible butyrylcholine esterase inhibitors based on calix[4]arene derivatives were suggested. A series of new distally disubstituted calix[4]arenes were prepared in 60–80% yields. Some of these compounds showed properties of reversible choline esterase effectors, activating it at low concentrations and inhibiting at high concentrations. The macrocycles prepared were tested in extraction of d,l-tartaric, glycolic, d,l-mandelic, d,l-glutamic, malonic, oxalic, and succinic acids and of sodium acetate. Oxalic acid is efficiently transferred through a liquid impregnated membrane under the action of calix[4]arenes with nitrogen-containing substituents.
提出了基于杯[4]芳烃衍生物的新型可逆丁酰胆碱酯酶抑制剂。制备了一系列新的远端二取代杯[4]芳烃,产率为 60-80%。其中一些化合物表现出可逆胆碱酯酶效应物的特性,在低浓度下激活它,在高浓度下抑制它。制备的大环化合物在d,l-酒石酸、乙醇酸、d,l-扁桃酸、d,l-谷氨酸、丙二酸、草酸和琥珀酸以及乙酸钠的提取中进行了测试。在具有含氮取代基的杯[4]芳烃的作用下,草酸有效地通过液体浸渍膜转移。
