A compact synthesis of 15 new binaphthyl-based dicationic tripeptoids and one biphenyl based dicationic tripeptoid is described. Fourteen of these tripeptoids resulted from variation of the C-2′ ether substituent of the binaphthyl unit. An O-iso-butyl ether binaphthyl derivative was found to be the most active against Staphylococcus aureus (MIC 1.95 μg/mL). The biphenyl analogue also showed good activity
描述了15种新的基于双萘基的双三倍体的紧密合成方法。这些三倍体中的十四个是由于双萘基单元的C-2'醚取代基的变化而引起的。一个ø -异丁基醚联萘衍生物被认为是针对最活跃的金黄色葡萄球菌(MIC 1.95微克/毫升)。联苯类似物还显示出对金黄色葡萄球菌的良好活性(MIC 1.95μg/ mL)。这些化合物,然而,对四名比一些我们的先前开发的化合物即有一个的肠球菌万古霉素抗性株(VRE)活性较低ø -异-戊基醚取代基的联萘单元和C-2上升-Leu部分。
