The tris-(catecholamide) (H6L) (8) was synthesised in six steps and characterized. This is the smallest analogue of naturally occurring siderophores structurally related to an approved enterobactin and protochelin model, known up to now.

Structure-function analysis with a series of N-sulfonyloxy beta-lactam molecules as inhibitors of beta-lactamases is reported. The best of these compounds acylate the active site of the class A TEM-1 beta-lactamase from Escherichia coli rapidly, and resist deacylation. Whereas acylation of the active site of the class C beta-lactamase from Enterobacter cloacae was not seen, these compounds function as competitive inhibitors of this enzyme.

We report that an amphiphilic bis-catechol (3) functions as a transmembrane anion transporter. Activity depends on the catechol's substitution and amphiphilicity. We also describe a liposomal assay that allows one to readily measure anion transport selectivity. This assay reveals that anion transport selectivity for this amphiphilic bis-catechol follows a Hofmeister sequence wherein anions that are easier to dehydrate are made more permeable to the membrane by 3.
