Abstract:

A series of imidazo(4,5-b)pyridinylethoxypiperidones was designed, synthesized and characterized for evaluation of potential antibacterial activity against Bacillus subtilis, Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa and antifungal activity against Candida albicans-6, Candida albicans, Aspergillus niger, Candida albicans-51 and Aspergillus flavus. Structure-activity relationship led to the conclusion that compound 39 exerted strong in vitro antibacterial activity against Bacillus subtilis and Staphylococcus aureus whereas compounds 38 and 39 displayed promising antifungal activity against Aspergillus flavus. The interesting antimicrobial profile of compound 39 led us to select this derivative for further development.

Basicity of Heterocyclic Aromatic Amines

Basicity of Heterocyclic Aromatic Amines

Heterocyclic amines, where the N atom is a part of an alicyclic system, are similar in basicity to alkylamines. Interestingly, the heterocyclic amine having a nitrogen atom as part of an aromatic ring has much less basicity than its corresponding alicyclic counterpart. For this reason, as presented in Figure 1, piperidine (pKb = 2.8) is significantly more basic than pyridine (pKb = 8.8).
