  Structure−Activity Relationship of 4(5)-Aryl-2-amino-1H-imidazoles, N1-Substituted 2-Aminoimidazoles and Imidazo[1,2-a]pyrimidinium Salts as Inhibitors of Biofilm Formation by Salmonella Typhimurium and Pseudomonas aeruginosa

  摘要：

  A library of 112 4(5)-aryl-2-amino-1H-imidazoles, 4,5-diphenyl-2-amino-1H-imidazoles, and N1-substituted 4(5)-phenyl-2-aminoimidazoles was synthesized and tested for the antagonistic effect against biofilm formation by Salmonella Typhimurium and Pseudomonas aeruginosa. The substitution pattern of the 4(5)phenyl group and the nature of the N1-substituent were found to have a major effect on the biofilm inhibitory activity. The most active compounds of this series were shown to inhibit the biofilm formation at low micromolar concentrations. Furthermore, the influence of 6 imidazo[1,2-a]pyrimidines and 18 imidazo[1,2-a]pyrimidinium salts on the biofilm formation was tested. These compounds are the chemical precursors of the 2-aminoimidazoles in our synthesis pathway. A good correlation was found between the activity of the imidazo[1,2-a]pyrimidinium salts and their corresponding 2-aminoimidazoles, supporting the hypothesis that the imidazo[1,2-a]pyrimidinium salts are possibly cleaved by cellular nucleophiles to form the active 2-aminoimidazoles. However, the imidazo[1,2-a]pyrimidines did not show any biofilm inhibitory activity, indicating that these molecules are not susceptible to in situ degradation to 2-aminoimidazoles. Finally, we demonstrated the lack of biofilm inhibitory activity of an array of 37 2N-substituted 2-aminopyrimidines, which are the chemical precursors of the imidazo[1,2-a]pyrimidinium salts in our synthesis pathway.

• CuI-Catalyzed Aerobic Oxidative α-Aminaton Cyclization of Ketones to Access Aryl or Alkenyl-Substituted Imidazoheterocycles

  CuI-catalyzed aerobic oxidative synthesis of imidazoheterocycles has been achieved. Four hydrogen atoms were removed in one step. This protocol was compatible with a broad range of functional groups, and it has been also successfully extended to unsaturated ketones, bringing about the formation of alkenyl-substituted imidazoheterocycles, which were difficult to prepare by previous means. Preliminary mechanistic studies indicated that this reaction was most likely to proceed through a catalytic Ortoleva-King reaction. By using this method, the marketed drug Zolimidine could be prepared with 90% yield on a gram scale from commercially available materials.

  An efficient method for the synthesis of mono- and disubstituted 2-amino-1H-imidazoles via microwave-assisted hydrazinolysis of substituted imidazo[1,2-a]pyrimidines is reported. This protocol avoids strong acidic conditions and is superior to the classical cyclocondensation of alpha-haloketones with N-acetylguanidine. (C) 2009 Elsevier Ltd. All rights reserved.
