3-Acetyl and 3-decanoyltetramic acids with various substituents at the 5-position and their copper complexes, which possess a tricarbonylmethane structure, were prepared and tested for antimicrobial activity. 3-Decanoyltetramic acid derivatives and their copper complexes inhibited the growth of Bacillus subtilis and Staphylococcus aureus, but did not inhibited the growth of gram-negative bacteria and molds. 3-(1-Iminoethyl)-tetramic acids and their copper complexes were synthesized and tested for inhibitory activity towards chlorophyll development in plants.
本研究制备了在 5 位上具有不同取代基的 3-乙酰基和 3-癸酰基四甲酸及其铜配合物(具有三羰基甲烷结构),并对其进行了抗菌活性测试。3-Decanoyltetramic acid 衍生物及其铜配合物能抑制枯草杆菌和金黄色葡萄球菌的生长,但不能抑制革兰氏阴性菌和霉菌的生长。合成了 3-(1-氨基乙基)-四酰胺酸及其铜络合物,并测试了它们对植物叶绿素发育的抑制活性。
