  Design, Synthesis, and Structure−Activity Relationships of Benzophenone-Based Tetraamides as Novel Antibacterial Agents

  摘要：

  The increase in the incidence of both hospital- and community-acquired antibiotic-resistant infections is a major concern to the healthcare community. There have been only two new classes of antibiotics approved by the FDA over the past 40 years, and clearly there is a growing need For additional antimicrobial agents. In this paper, we present Our work on the discovery of a class of benzophenone containing compounds that possess good activity against MRSA, VISA, VRSA, and VRE and moderate activity against E. coli. These compounds display MIC values in the 0.5-2.0 mg/L range and are not cytotoxic against mammalian cells. Extensive structure-activity relationship studies revealed that the benzophenone was absolutely essential for antibacterial activity as was the presence of a cationic group. Although these agents display DNA binding activity, we observed that these compounds do not inhibit any macromolecular synthesis reliant upon DNA nor do they inhibit lipid or cell wall biosynthesis. Instead, we found that these agents cause membrane depolarization, indicating that the bacterial membrane was the primary site of action for these agents. Our studies Suggest that caution should be taken ill assigning the mechanism of action for DNA binding antibiotics.

  Nine novel lexitropsins were synthesized by linking two netropsin-like moieties through three different dicarboxylic acids; 9,10-dihydro-2,7-phenanthrenedicarboxylic acid; [(3-[(carboxymethyl)amino]carbonyl}benzoyl)amino]acetic acid and indole-2,5-dicarboxylic acid. The netropsin residues were modified by the use of N-isopentylpyrrole, 5-methylthiophene or 5-isopropylthiazole heterocyclic building blocks in place of the usual N-methylpyrrole. The compounds were tested against five gram-positive bacteria: Staphylococcus aureus, Streptomyces faecalis, methicillin resistant Staphylococcus aureus, Enterobacter cloacae, Mycobacterium fortuitum, three gram-negative bacteria: Klebsiella aerogenes, Proteus vulgaris, Escherichia coli and three fungi: Aspergillus niger, Candida albicans and Aspergillus nidulans. Some of the compounds showed significant inhibitory effects on the growth of the microorganisms.

  合成了九种新型lexitropsin，通过三种不同的二羧酸（9,10-二氢-2,7-菲二羧酸；[(3-[(羧甲基)氨基]羰基}苯甲酰)氨基]乙酸和吲哚-2,5-二羧酸）将两个类似netropsin的部分连接在一起。通过使用N-异戊基吡咯、5-甲基噻吩或5-异丙基噻唑异构体构建单元替代通常的N-甲基吡咯，对netropsin残基进行修饰。将这些化合物分别针对五种革兰阳性菌：金黄色葡萄球菌、肠球菌、耐甲氧西林金黄色葡萄球菌、克雷伯氏菌和偶然分枝杆菌，三种革兰阴性菌：气单胞菌、变形杆菌、大肠杆菌，以及三种真菌：黑曲霉、白念珠菌和安氏曲霉进行了测试。其中一些化合物对微生物的生长表现出显著的抑制作用。
