Abstract

The cyclohexane triones are a novel group of synthetic antibacterial agents that are active against gram-positive bacteria, Haemophilus influenzae, and Mycobacterium smegmatis. In general, these compounds behaved in a manner similar to that of hexachlorophene, inhibiting the transport of low-molecular-weight hydrophilic substances into bacteria. Unlike cationic detergents, such as chlorhexidine, they did not cause disruption of the bacterial cytoplasmic membrane over a short time period. The most potent antibacterial cyclohexane trione studied had a reduced ability to inhibit solute transport in comparison with certain less active analogs. Cyclohexane triones may express more than a single type of antibacterial effect.

摘要

环己烷三酮是一类新型合成抗菌剂,对革兰氏阳性菌、流感嗜血杆菌和耻垢分枝杆菌具有活性。一般来说,这些化合物的行为方式与六氯酚相似,可抑制低分子量亲水性物质向细菌内的转运。与阳离子洗涤剂(如洗必泰)不同,它们在短时间内不会导致细菌细胞质膜破裂。与某些活性较低的类似物相比,所研究的最有效的抗菌环己烷三酮抑制溶质转运的能力有所降低。环己烷三酮可能表现出不止一种类型的抗菌作用。
