Abstract

A novel series of 1,2,3-triazole-benzimidazolidinone hybrid derivatives were designed and synthesized via click reaction, between various aryl azide and a terminal alkyne bearing a benzimidazolidinone moiety. All newly synthesized compounds, were efficiently characterized using 1H NMR, 13C NMR and HRMS. Furthermore, the structure of one precursor 5b was supported by single crystal X-ray diffraction. All synthesized derivatives have been evaluated for their antimicrobial and anti-inflammatory activities. Biological activity tests exhibited that the target structures demonstrate that compounds 5a, 5b and 5f have a high antibacterial activity especially derivative 5b. Besides, the in vitro antifungal results revealed that the strongest inhibition recorded to compound 5b in comparison to other products against A. brasiliensis, A. fumigatus and C. albicans. Biological activity evaluation indicated that the synthesized compounds possess moderate anti-inflammatory effects. The most effective compound in terms of efficacy and potency was 5a. Molecular docking simulation was used to investigate the most active compounds' probable binding mechanisms in order to provide a plausible explanation for their biological activity.
