A variety of novel bis-thiazolopyridine derivatives 4a-e were synthesized via the reaction of bis-thiazolinone 3 with different arylcinnamonitrile derivatives (1:2 molar ratio), whereas the reaction of bis-compounds 7a-e with malononitrile in ethanol solution containing a few drops of piperidine afforded the novel bis-thiazolopyridines 8a-e. The structures of the synthesized compounds were established by elemental analyses and spectral data. Some of the newly synthesized compounds show moderate to high antimicrobial activity.

UI	MeSH Term	Description	Entries
D011725	Pyridines	Compounds with a six membered aromatic ring containing NITROGEN. The saturated version is PIPERIDINES.
D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
