Background: The imidazole nucleus is inimitable and ubiquitous and it is very well known to play an important role in living organisms. Imidazole derivatives are under intensive scientific exploration due to their diverse and significant pharmacological activities.
Methods: The present paper is an attempt to discuss chemistry, synthetic aspects including click chemistry procedures of imidazoles through systematic literature survey.
Results: Biological activity profiles of the imidazole derivatives reported in recent scientific literature from 2000 to 2015 have been discussed in detail. It has been found that imidazole derivatives depict appreciable antiinfective activity potential.
Conclusion: It is anticipated that the information compiled in this paper will be useful and motivating to prospective researchers working on this heterocylic scaffold.

Two artificial imidazole-derived nucleobases, HQIm (3H-imidazo[4,5-f]quinolin-5-ol) and CaIm (imidazole-4-carboxylate), were introduced into short DNA duplexes to systematically investigate their thermal stability upon metal ion coordination. Metal-mediated base pairs are formed with the 3d metal ions CoII, NiII and ZnII, as well as with the lanthanoid ions EuIII and SmIII, which induce a thermal stabilization of up to 8 °C upon binding. The latter are the first lanthanoid-mediated base pairs involving only four donor atoms that result in a significant duplex stabilization.

The covalently attached cofactor biotin plays pivotal roles in central metabolism. The top-priority ESKAPE-type pathogens, and , constitute a public health challenge of global concern. Despite the fact that the late step of biotin synthesis is a validated anti-ESKAPE drug target, the primary stage remains fragmentarily understood.

Electrochemical capacitors (ECs) offer superior specific capacitance for energy storage compared to traditional electrolytic capacitors but face limitations in alternating current (AC) filtering due to the need for balancing fast response and high capacitance. This study addresses these challenges by developing a freestanding nanostructured carbon electrode, derived from the rapid carbonization of bacterial cellulose (BC) embedded with zeolitic imidazolate framework 8 (ZIF-8) and in situ formed carbon nanotubes (CNTs). The electrode exhibits an exceptionally low area resistance of 9.

The antibiotic 2-nitroimidazole (2NI) or azomycin, used for treating drug-resistant tuberculosis and imaging tumor hypoxia, requires activation by bacterial nitroreductases for its antibiotic and cytotoxic effect. Mycobacterium sp. JS330 produces 2-nitroimidazole nitrohydrolase (NnhA) that circumvents 2NI activation, conferring 2NI resistance by hydrolysing it to nitrite and imidazol-2-one (IM2O) instead.
