Syntheses of benzoyl, cinnamoyl, and benzoylhydrazido glyoxyloyl aminoacyl penicillins with and without acylated catechol substituents by condensation of corresponding acids or acylchlorides with ampicillin or amoxycillin and also of a 6-α-methoxy-derivative and corresponding esters are reported. Acylated catechol substituents improve the antibacterial activity against Gram-negative bacteria, especially against Pseudomonas strains and Salmonella. MIC tests of bacterial mutants with higher outer membrane penetrability and of the corresponding wild type show that the increase of antibacterial activity by catechol substituents is caused by improvement of the penetration through the bacterial outer membrane. The affinity to penicillin binding proteins is not influenced by catechol substitutents. Stability against β-lactamases is partly higher than that of azlocillin.
