4 µM) and were safe to human keratinocytes. Compound 19, with an additional isonitrile group exhibited improved activity against MRSA compared to the first-generation lead compound. This compound emerged as a candidate worthy of further investigation and further reinforced the importance of the isonitrile functionality in the compounds' anti-MRSA activity. In a murine skin wound model, 19 significantly
抗生素耐药性仍然是全球主要的公共卫生威胁,需要不断发现具有未开发脚手架的新型抗菌剂。我们合成的第一代芳基异腈化合物的结构活性关系导致了一个最初的先导分子,该分子指导了第二代芳基异腈的合成。在这个由20种化合物组成的新系列中,三种类似物可抑制耐甲氧西林的金黄色葡萄球菌(MRSA)(从1至4 µM)的生长,并且对人角质形成细胞安全。与第一代先导化合物相比,具有额外的异腈基的化合物19表现出对MRSA改善的活性。该化合物成为值得进一步研究的候选化合物,并进一步增强了异腈功能在该化合物的抗MRSA活性中的重要性。在鼠类皮肤伤口模型中,19与抗生素夫西地酸相似,可显着降低MRSA的负担。总之,已鉴定出19种化合物对MRSA有效。
