determined by surface tension and conductivity measurements. The products were evaluated as surface‐active agents as well as corrosioninhibitors for steel alloy in 1 M hydrochloric and sulfuric acid, the results indicate that these materials have a high efficiency as corrosioninhibitors and as surface active agents. These results were correlated with the chemical structure of the prepared compounds.

Among the various antimicrobial resistant bacterial strains, methicillin and vancomycin resistant Staphylococcus aureus are among the most dreadful, causing serious complications. On the basis of the hypothesis that microbes have reduced ability to develop resistance against membrane targeting antibiotics, bile acid oligomers having unique facially amphiphilic topologies were designed and synthesized
