Methyl anthranilate inhibits elastase production by P. aeruginosa. Elastase activities were determined for cell-free supernatants of P. aeruginosa strains PAO1 (solid bars) and PAO-JP3 (striped bars) grown in the presence of increasing amounts of methyl anthranilate. Activity is reported as a percentage of activity seen from the wild-type P. aeruginosa strain PAO1 grown without methyl anthranilate. Data are the mean + σⁿ⁻¹ from duplicate assays performed during three separate experiments.
