喷他脒是一种 FDA 批准的抗寄生虫药,最近被鉴定为一种外膜破坏增效剂,可增强红霉素、利福平和新生霉素对革兰氏阴性菌的作用。同一项研究还描述了使用市售喷他脒类似物的初步构效关系。我们在这里报告了受喷他脒启发的更广泛的双脒组的设计、合成和评估。本研究既验证了先前观察到的喷他脒的协同活性,同时进一步评估了结构相似的双脒增强革兰氏阳性特异性抗生素对抗革兰氏阴性病原体的能力。在制备的双脒中,发现其中一些表现出比喷他脒更大的协同活性。鲍曼不动杆菌、肺炎克雷伯菌、铜绿假单胞菌和大肠杆菌,包括耐多粘菌素和碳青霉烯的菌株。
The present invention relates to the use of amidine compounds in the treatment of amyloid-related diseases. In particular, the invention relates to a method of treating or preventing an amyloid-related disease in a subject comprising administering to the subject a therapeutic amount of an amidine compound. Among the compounds for use according to the invention are those according to the following Formula, such that, when administered, amyloid fibril formation, neurodegeneration, or cellular toxicity is reduced or inhibited:

observed synergisticactivity reported for pentamidine, while further assessing the capacity for structurally similar bis-amidines to also potentiate Gram-positive specific antibiotics against Gram-negative pathogens. Among the bis-amidines prepared, a number of them were found to exhibit synergisticactivity greater than pentamidine. These synergists were shown to effectively potentiate the activity of
