The synthesis, biological assessment, and molecular modelling of new tacrine analogues 11–22 is described. Compounds 11–22 have been obtained by Friedländer-type reaction of 2-aminopyridine-3-carbonitriles 1–10 with cyclohexanone or 1-benzyl-4-piperidone. The biological evaluation showed that some of these molecules were good AChE inhibitors, in the nanomolar range, and quite selective regarding the

simulation methods. Schiffbases were tested for antimicrobial activity against bacterial species Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Staphylococcus aureus by the disc diffusion method. The pharmacological treatment of Schiffbases showed that 1–8 have promising potential against tested bacterial strains. The molecular docking study of the target compounds was also carried

5-dicarbonitrile (2) is described. The biological evaluation showed that some of these molecules were modest inhibitors of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), in the micromolar range. The 2-amino (3, 4), and 2-chloro derivatives 21–23, 25, 26 were AChE selective inhibitors, whereas 2-amino derivatives 5, 14 proved to be selective for BuChE. Only inhibitor 24 was equipotent
A convenientsynthesis of 4-amino-7-(dialkylamino)pyrido[2,3-d]pyrimidines via cyclization of functionalized pyridines is reported. The preparation of the starting pyridinesfrom 3-amino-3-(dialkylaraino)propene-nitriles and ethoxymethylenemalononitrile is described.
