Replacement of amide moiety with the 1,2,4-oxadiazole core in the scaffold of recently reported efflux pump inhibitors afforded a novel series of oxadiazole/2-imidazoline hybrids. The latter compounds exhibited promising antibacterial activity on both Gram-positive (Staphylococcus aureus, Bacillus subtilis) and Gram-negative (Escherichia coli, Pseudomonas fluorescens) strains. Furthermore, selected compounds markedly inhibited the growth of certain drug-resistant bacteria. Additionally, the study revealed the antiproliferative activity of several antibacterial frontrunners against pancreas ductal adenocarcinoma (PANC-1) cell line, as well as their type-selective monoamine oxidase (MAO) inhibitory profile.
将最近报道的外流泵抑制剂中的酰胺基团替换为1,2,4-噁二唑核心,在支架中得到了一系列新颖的噁二唑/2-咪唑啉杂化物。后一类化合物在革兰氏阳性(金黄色葡萄球菌,枯草芽孢杆菌)和革兰氏阴性(大肠杆菌,荧光假单胞菌)菌株上表现出有希望的抗菌活性。此外,选择性化合物显著抑制了某些耐药细菌的生长。此外,该研究揭示了几种抗菌前沿药物对胰腺导管腺癌(PANC-1)细胞系的抗增殖活性,以及它们的选择性单胺氧化酶(MAO)抑制剖面。
