  A novel series of 1-acetyl-3,5-diphenyl-4,5-dihydro-(1H)-pyrazole derivatives have been synthesised and investigated for the ability to inhibit selectively monoamine oxidases, swine kidney oxidase, and bovine serum amine oxidase. The newly synthesised compounds 1-6 proved to be reversible and non-competitive inhibitors of all types of the assayed amine oxidases. Compounds inhibit monoamine oxidases potently, displaying low 150 values of particular interest. In particular 1-acetyl-3-(2,4-dihydroxyphenyl)-5-(3-methylphenyl)-4,5-dihydro-(1H)-pyrazole 6 showed to be a potent monoamine oxidase inhibitor with a K-i of about 10(-8) M. Further insights in the theoretical evaluation of the possible interactions between the compounds and monoamine oxidase B have been developed through a computational approach.

  An aminoacylation/translation (AIT) system based on the protein synthesis system from the pathogen Pseudomonas aeruginosa , was used to screen chemical compounds for identifying inhibitors of protein synthesis. This system includes elongation factors: EF-Tu, EF-Ts and EF-G, aminoacyl tRNA synthetase (aaRS) specific for phenylalanine, PheRS, and ribosomes isolated from cultures of Pseudomonas aeruginosa . Compounds identified using this assay have been shown to contain broad spectrum activity against both Gram+ and Gram− pathogens. Methods of using the identified compounds, as well as derivatives and analogues of these compounds, as antimicrobial agents against bacterial infections are described.
