چکیده
A series of novel substituted benzimidazole (7a - n) derivatives were synthesized and characterized by 1H, 13C Nuclear Magnetic Resonance (NMR) spectra High Resolution Mass Spectrometry (HRMS). The substitution was done in position -1 -2 appropriate groups. These compounds are obtained N-alkylation reaction with thiomethyl-1H-benzimidazole intermediates (5a g). Design g) made condensation between 2-methylbenzimidazole thiourunium salt (3) functionalized halides (4) the presence sodium hydroxide (NaOH). Among twenty-one synthesized, ten evaluated for their antimicrobial activity on three bacterial strains namely: Escherichia coli ATCC 25922, Staphylococcus aureus 25923 Pseudomonas aeruginosa 27853. Only E. ATTC 25922 susceptible to 5g, 7f 7h a significant antibacterial (CMI is 250 500 μg/mL).

Benzodiazepines are useful drugs for treatment of sleep disorders, anxiety, seizure cases and skeletal muscle cramps. Some derivatives of 2-(2-Phenoxy) phenyl-1, 3, 4-oxadiazole were synthesized as benzodiazepine receptor agonists. Conformational analysis and superimposition of energy minima conformers of the compounds on estazolam, a known benzodiazepine agonist, reveal that the main proposed ...

Two series of benzimidazole derivatives were sythesised. The first one was based on 5,6-dinitrobenzimidazole, the second one comprises 2-thioalkyl- and thioaryl-substituted modified benzimidazoles. Antibacterial and antiprotozoal activity of the newly obtained compounds was studied. Some thioalkyl derivatives showed remarkable activity against nosocomial strains of Stenotrophomonas malthophilia...
