An imidazopyridine is a nitrogen containing heterocycle that is also a class of drugs that contain this same chemical substructure. In general, they are GABA A receptor agonists , however recently proton pump inhibitors , aromatase inhibitors , NSAIDs and other classes of drugs in this class have been developed as well. Despite usually being similar to them in effect, they are not chemically related to benzodiazepines. As such, GABA A -agonizing imidazopyridines, pyrazolopyrimidines , and cyclopyrrones are sometimes grouped together and referred to as " nonbenzodiazepines. NSAIDs , analgesics and antimigraine drugs:.

Imidazopyridine scaffold has gained tremendous importance over imidazopyridine past few decades. Huang, X. Boerner R.

A CuI-catalyzed aerobic oxidative synthesis of imidazo[1,2- a ]pyridines from 2-aminopyridines and acetophenones is compatible with a broad range of functional groups. The reaction also enables the formation of alkenyl-substituted imidazoheterocycles by using unsaturated ketones as substrates. Preliminary mechanistic studies indicate that this reaction proceeds through a catalytic Ortoleva-King reaction. Zhang, Z. Chen, W.

The structural resemblance between the fused imidazopyridine heterocyclic ring system and purines has prompted biological investigations to assess their potential therapeutic significance. They are known to play a crucial role in numerous disease conditions. The discovery of their first bioactivity as GABA A receptor positive allosteric modulators divulged their medicinal potential. Imidazopyridines have the ability to influence many cellular pathways necessary for the proper functioning of cancerous cells, pathogens, components of the immune system, enzymes involved in carbohydrate metabolism, etc. The collective results of biochemical and biophysical properties foregrounded their medicinal significance in central nervous system, digestive system, cancer, inflammation, etc. In recent years, new preparative methods for the synthesis of imidazopyridines using various catalysts have been described. The present manuscript to the best of our knowledge is the complete compilation on the synthesis and medicinal aspects of imidazo[4,5- b ]pyridines and imidazo[4,5- c ]pyridines reported from the year to date, including structure—activity relationships.

Imidazopyridines constitute one of the most important scaffolds in medicinal chemistry, as their skeleton could be found in a myriad of biologically active molecules. Although numerous strategies were elaborated for imidazopyridine preparation in the s, novel eco-compatible synthetic approaches have emerged, conscious of climate change concerns. In this framework, photochemical methods have been promoted to conceive this heterocyclic motif over the last decade. This review covers the recently published works on synthesizing highly functionalized imidazopyridines by light induction. Imidazopyridines have had a long-lasting interest in organic and medicinal chemistry [ 1 , 2 , 3 ]. These heterocyclic scaffolds have broadly been found in many pharmaceuticals with various biological activities. For example, saripidem or alpidem are hypnotic drugs that are chemically distinct from benzodiazepines but bind at the same site on the receptor.

MD simulation was done applying the Gromacs Figure 2. Moreover, structural integrity of spheroids was also quantified and a dose-dependent decrease in circularity and optical density was observed after treatment with all 3 test compounds Fig. The equilibrium time ranges of 44, 15 and 55 ns were observed for complexes of 6d , 6e and 6f with c-Met, respectively. According to the c-Met inhibition results illustrated in Table 1 , it could be clearly understood that the lipophilic nature of substituents enhances the inhibitory potency of compounds against c-Met kinase.

Devi et al. Institutional Review Board Statement Not applicable. The prepared IZPs reacted with substituted benzaldehyde and malononitrile or ethyl cyanoacetate in a three-component reaction. An evaluation of the antibacterial qualities of IZPs suggested the involvement of various pathways in their mechanism of action. Ng, J. After 48 h, the synthesized derivatives at different concentrations were added and incubated for 24 h. Temporary Price Reductions. Boominathan, S.
