antibacterial, antiproliferative, and cytotoxic activities. The length of the alkyl side chain and the nature of the amino acid residues within the tetramic acid moiety strongly affected activity, in particular against mycobacteria. The mode of action was shown to correlate with the ability of pyreudiones to act as protonophores. Removal of the acidic proton by methylation of pyreudione A resulted in
微生物产生的3-酰基四酸显示出多种生物活性。吡啶二酮是从假单胞菌属细菌中分离出来的这类新成员。在这里,我们进行了结构-活性关系研究,并确定了它们的作用方式。开发了一种有效的仿生合成法来合成吡啶酮二酮。测试了吡啶酮及其合成类似物的杀螨,抑菌,抗增殖和细胞毒性活性。烷基侧链的长度和四氨基酸部分内氨基酸残基的性质强烈影响了活性,特别是抗分枝杆菌的活性。已显示作用方式与吡啶二酮充当质子体的能力相关。
