Bioactive imidazole derivatives were synthesized and characterized by spectral techniques. The photophysical properties of imidazole derivatives were studied in several solvents. The observed spectral shift is attributed to a loss of planarity in the excited state provided by the non-co-planarity of the aryl rings attached to C(2) and N(1) atoms of the imidazole ring. The observed solvatochromic shifts were analyzed in detail by Kamlet-Taft and Catalan parameters. The interaction between bioactive imidazole derivative and bovine serum albumin (BSA) was also investigated.

Diabetic peripheral neuropathy (DPN) is a common complication of diabetes in both Type 1 (T1D) and Type 2 (T2D). While there are no specific medications to prevent or treat DPN, certain strategies can help halt its progression. In T1D, maintaining tight glycemic control through insulin therapy can effectively prevent or delay the onset of DPN.

Silver drugs have played a vital role in human healthcare for the treatment of infections for many centuries. Currently, due to antibiotic resistance, a potential scenario or the application of silver complexes may arise as substitutes for conventional antibiotics. In this perspective, N-heterocyclic carbene (NHC) ligands have been selected as carrier molecules for silver ions.

Diabetes exacerbates periodontitis by overexpressing reactive oxygen species (ROS), which leads to periodontal bone resorption. Consequently, it is imperative to relieve inflammation and promote alveolar bone regeneration comprehensively for the development of diabetic periodontal treatment strategies. Furthermore, an orderly treatment to avoid interference between these two processes can achieve the optimal therapeutic effect.

A Cu-catalyzed relay process for the preparation of diazidated quinazolinone and polycyclic imidazole derivatives in which readily available alkene-tethered substrates undergo an addition/cyclization/C(sp)-H functionalization of alkene sequences with high efficiency is described. Various functionalized N-heteropolycyclic compounds were readily prepared in good yields with a broad substrate scope. Moreover, the direct azidation of the α-C(sp)-H bond of the corresponding N-heterocycles has been demonstrated on the basis of mechanistic studies, which provide an alternative late-stage functionalization approach for the derivatization of N-heterocyclic scaffolds.

Cushing's disease is a rare endocrine disorder characterized by hypercortisolism. Chronic elevated cortisol levels can lead to dysfunction or complications in multiple organs of systems, including cardiovascular, glucose, and bone metabolism, severely impacting patients' quality of life and posing life-threatening risks. Surgery is the first-line treatment for Cushing's disease.
