A series of novel 3-[N, N-bis(2-hydroxyethyl)-amino]-chalcone derivatives 3a–3j were synthesized by the aldol condensation of [N, N-bis(2-hydroethyl)-3-amino]-acetophenone 2 with aromatic aldehydes. Their structures were further confirmed by ESI-HRMS, 1H NMR, IR and elemental analysis. X-ray analysis reveals crystal 3b is a monoclinic system with P21/n space group. The antimicrobial activities of the newly synthesized chalcones in vitro were evaluated and the results indicated that most compounds presented moderate to good antimicrobial activities, especially the antifungal capability. Compounds 3a, 3d, 3f and 3g revealed obvious potency against Candida albicans with MIC values of 32 μg/mL, which were better compared with others.
通过[N,N-双(2-羟乙基)-3-氨基]-苯乙酮 2 与芳香醛的醛缩合反应,合成了一系列新型 3-[N,N-双(2-羟乙基)-氨基]-查尔酮衍生物 3a-3j。它们的结构通过 ESI-HRMS、1H NMR、IR 和元素分析得到了进一步证实。X 射线分析表明晶体 3b 为单斜体系,具有 P21/n 空间群。对新合成的查耳酮化合物进行了体外抗菌活性评价,结果表明大多数化合物具有中等至良好的抗菌活性,尤其是抗真菌能力。化合物 3a、3d、3f 和 3g 对白色念珠菌具有明显的抗菌活性,其 MIC 值为 32 μg/mL,优于其他化合物。
