In pursuit the development of novel potent and selective antibacterial agents, we synthesized twelve (12) N-alkyl 2-benzylthiomethyl-1H-benzimidazole derivatives evaluated their activities. Their profile was determined with minimal inhibitory concentrations (MICs) minimum bactericidal (MBCs) against a small set two (2) strains Escherichia coli (Gram negative) Staphylococcus aureus positive). Th...

A series of benzimidazole-2-thione derivatives was synthesized using a reaction between the macrocyclic aminal 16H,13H-5:12,7:14-dimethanedibenzo[d,i]-[1,3,6,8] tetraazecine (DMDBTA, 5) and various nucleophiles in the presence of carbon disulfide. A full chemical characterization using IR, ¹H-, ¹³C-NMR and GC-MS analyses of the new compounds is provided. These compounds were separated from the ...

The trace impurities discovered after extended storage of a 5-amino- benzimidazole library were determined as imidazo[4,5-g]quinazoline derivatives by extensive spectroscopic data analysis. The formation of this highly aromatic heterocyclic ring involved a novel multi-component reaction, using which several novel compounds were prepared. Its mechanism was deduced as a cascade of chemical transf...

One of the most important goals in medicinal chemistry is the development of new heterocyclic compounds with pharmaceutical activity. Thus, a novel series of the derivatives of benzimidazole were synthesized and the structures of all the synthesized compounds have been confirmed by IR, 1 H- and 13C-NMR, Mass Spectroscopy and elemental analysis. The title compounds have been evaluated for antifu...

Sharma Dept. of Pharmaceutical Sciences, Dr.Hari Singh Gour University Sagar (M.P) 470003 India Department of Chemistry Yadhunath Mahavidyalya Bhind (M.P) 477001 India Email: [email protected] Abstract A new series of non peptide angiotensin (A-II) receptor antagonist has been prepared. This N-(biphenyl methyl) imidazoles e.g. Some new 4'-{5-amino2-[2-substituted-phenylamino)-ph...

Benzyl-o-vanillin and benzimidazole nucleus serve as important pharmacophore in drug discovery. The benzyl vanillin (2-(benzyloxy)-3-methoxybenzaldehyde) compound shows anti-proliferative activity in HL60 leukemia cancer cells and can effect cell cycle progression at G2/M phase. Its apoptosis activity was due to disruption of mitochondrial functioning. In this study, we have studied a series of...

This study addressed the design and syntheses of diverse ligands, which were then successfully treated with Ni (II) ion to afford a series of nickel complexes. α-Chloroformylarylhydrazine hydrochlorides contain two different functional groups. One is a strong nucleophile, and the other is a good electrophile. Therefore, it can be designed to react with several reagents to obtain diverse derivat...

The synthesis of a series of benzimidazole-N-benzylpropan-1-amines and adenine-N-benzylpropan-1-amines is described. Subsequent evaluation against two strains of the anaerobic bacterium Clostridium difficile was performed with three amine derivatives displaying MIC values of 16 μg/mL. Molecular docking studies of the described amines determined that the amines interact within two active site po...

A new series of bis-benzimidazole derivatives was designed and synthesized. In vitro cytotoxity evaluation showed that these compounds exhibited high activity against the selected tumor cells. Among them, compound 8 owned the best potential, its IC50 values being 0.58 μM (mononuclear tumor cell line (U937)) and 0.56 μM (cervical cancer cell (Hela)), respectively. Molecular modeling, fluorescenc...

A new 3D porous anionic MOF (AMOF-1) based on Zn(II) and a flexible tetracarboxylate linker has been synthesized. AMOF-1 showed potential for capture and removal of toxic metal ions from aqueous solution with a detection limit in the ppm level. The Cu(II)@AMOF-1' hybrid obtained by post-synthetic metalation is studied as a heterogeneous catalyst for the synthesis of benzimidazole derivatives.
