Table 2. Antimicrobial activity of ponericins.

Minimum inhibito1y concentrations (MIC, μM) of synthetic ponericins, colistin, and vancomycin against Gram negative and Gram-positive bacterial pathogens from the genera Escherichia, Klebsiella, Acinetobacter, Pseudomonas, Staphylococcus and Bacillus. MIC values below 3 μM are shown in bold and shaded.
