On the basis of a previously observed correlation between the antimicrobial activity and DNA binding strength of dicationic molecules, a series of 10 dicationically substituted bis-benzimidazoles were tested for activity in the rat model of Pneumocystis carinii pneumonia. One of the compounds, 1,4-bis[5-(2-imidazolinyl)-2-benzimidazolyl]butane, was found to be more potent and less toxic than pentamidine.
基于先前观察到的双阳离子分子的抗菌活性与DNA结合强度之间的相关性,对一系列10种双阳离子取代的双苯并咪唑进行了卡氏肺孢子虫肺炎大鼠模型中的活性测试。其中一种化合物,1,4 - 双[5 - (2 - 咪唑啉基)-2 - 苯并咪唑基]丁烷,被发现比喷他脒更有效且毒性更小。
