The facile synthesis of seven new dicationic tripeptide benzyl ester derivatives, with hydrophobic group variations in the C-terminal amino acid component, is described. Moderate to good activity was seen against Gram-positive bacteria in vitro. One cyclohexyl-substituted compound 2c was tested more widely and showed good potency (MIC values ranging from 2–4 μg/mL) against antibiotic-resistant strains of Staphylococcus aureus and Enterococci (VRE, VSE), and against Staphylococcus epidermidis.

The catalytic activity of two common bacterial enzymes, lactate dehydrogenase (LDH) and cytochrome c oxidase (COX) from Escherichia coli, was examined following bacterial exposure to microwave (MW) radiation under well-defined experimental conditions. The experiments were conducted in a specialised microwave processing apparatus, with an exposure frequency of 18 GHz, and a temperature profile that was restricted to below 40oC to avoid thermal degradation of the bacteria. The absorbed power was calculated to be 1500 kW/m3 and the electric field was determined to be 300 V/m. Both values were theoretically confirmed using Computer Simulation Technology (CST) Microwave Studio 3D Electromagnetic Stimulation …
