Article Abstract
Benzimidazole is a vital moiety found in a wide range of naturally and pharmacologically active molecules. We prepared a proficient and facile manganese oxide-supported magnesium and aluminium-based nanocomposite catalytic framework using the deposition-precipitation method and characterised it with XRD, XPS, SEM, TEM, and TGA techniques. Following that, the catalyst was used in the green synthesis of highly functional 2-substituted benzimidazole derivatives in an ethanol-water solvent system at room temperature using various assorted benzaldehydes and -phenylenediamine as substituents. The synthesised catalyst operates efficiently and is applicable to a wide range of electron-withdrawing and electron-donating substrates, resulting in good to excellent yields. The advantages of this process include the use of a greener solvent, high yield, high conversions, no use of additives or bases, a good TOF, and a shorter reaction time.

The 2-substituted benzimidazole has emerged as a promising heterocyclic compound in the field of drug design. In pursuit of more sustainable photocatalysts for 2-substituted benzimidazole synthesis, the method for coating FeO with V-doped TiO was presented. On the base of characterizing composition, morphology, and properties, the prepared nano-sized FeO@V/TiO composites were used as a heterogeneous photocatalyst to catalyze the synthesis of 2-substituted benzimidazoles under light.

Many non-steroidal anti-inflammatory drugs (NSAIDs) concurrently inhibit both COX-1 and COX-2, with a preference for specifically targeting COX-2 due to its significant involvement in various pathologies. In addition to COX enzymes, several other targets, including Aldose reductase, Aldo-ketoreductase family 1-member C2, and Phospholipase A2, have been identified as contributors to inflammation and a myriad of other diseases. In this context, a series of 2-substituted benzimidazole derivatives was synthesized and assessed for their anti-inflammatory potential through both in vitro and in vivo assays.

Improving lipophilicity for drugs to penetrate the lipid membrane and decreasing bacterial and fungal coinfections for patients with cancer pose challenges in the drug development process. Here, a series of new N-alkylated-2-(substituted phenyl)-1-benzimidazole derivatives were synthesized and characterized by H and C NMR, FTIR, and HRMS spectrum analyses to address these difficulties. All the compounds were evaluated for their antiproliferative, antibacterial, and antifungal activities.
