“…The interaction of o-aminonitrile derivative 2 with cyanoacetone in dry DMF [37] gave the corresponding pyridothienopyridine-3-carbonitrile derivative 7 "(Scheme 2)". Cyclization of compound 7 upon refluxing in formic acid only [38] afforded the pyrimidinone derivative 8. The IR spectrum of compound 8 showed a broad absorption band at 3416 cm -1 due to the tautomeric OH group besides a band at 1719 cm -1 corresponding to C=O function.…”

Therapeutics are compounds, which do not always exhibit healing powers. They sometimes prevent or control roles. Many compounds, well known or less are treated as the therapeutic agents. Among them, there is a specific group of molecules named commonly as Schiff bases, chemically imines. Schiff bases are aldehyde-or ketone-like compounds in which the carbonyl group is replaced by an imine -HN=СН-or azomethine -NHN=СН-group, they are an important class of compounds for new drug development. Schiff base modifications so far proved to be very effective with increased efficacy and reduced toxicity. Therefore, many researchers have synthesized these compounds as target structures and evaluated their biological activity. The aim of this work was to present some interesting and promising examples of Schiff bases which exhibit biological activity.

Reaction of 2-amino-4-phenylthiazole with various aromatic aldehydes afforded 2-arylideneamino-4-phenylthiazoles. On the other hand treatment of 2-amino-4-phenylthiazole with several acyl halides furnished N-(thiazol-2-yl)-amides. The synthesized compounds have been screened for their antimicrobial activity against Bacillus cereus, Bacillus subtilis, Staphylococcus aureus, Shigella dysenteriae, Salmonella typhi, Pseudomonous sp. bacteria and Aspergillus niger, Penicillium notatum, Aspergillus funiculosus, Collectrichum corchori Ikata (Yoshida) and Curvularia lunata fungi respectively. Some of the synthesized compounds exhibited pronounced antimicrobial activities.Keywords: Aminothiazole; Arylideneaminothizole; N-(Thiazol-2-yl)-amide; Antimicrobial activity.© 2011 JSR Publications.
