Green Synthesis of Benzimidazole Derivatives: A Sustainable Approach Towards Potent Antimicrobial Agents

Abstract

Introduction: Since medicinal products benzimidazole and hydrating agents are important antimicrobials, specific substances including benzimidazole hydrazone have been generated in order to test their effectiveness against bacteria. The molecular makeup of the newly synthesised compounds was clarified using the analysis of elements along with 1H-NMR measurements, infrared radiation along with ES-MS spectrum evidence. following the synthetic chemicals' assessing subsequently was discovered that the ability to kill bacteria is increased by the inclusion of Schiff bases and specific compound groups implanted beneath either benzimidazole nuclear structures along with modified nucleus. Every variant exhibited little action against microbes with Gram-negative DNA and strong performance against bacteria that are Gram-positive. When examined towards fungus, several of the freshly synthesised compounds exhibited modest potency.

Objectives: Comparative study newly microwave irradiation synthesis of substituted benzimidazole and evaluation of its antimicrobial activity which is resistance to pathogen.

Methods: The molecular makeup of the newly synthesised compounds was clarified using the analysis of elements along with 1H-NMR measurements, infrared radiation along with ES-MS spectrum evidence. The synthetic strategy included microwave-assisted reactions and TLC verification.

Results: The ability to kill bacteria was increased by the inclusion of Schiff bases and specific compound groups implanted beneath benzimidazole nuclei with modified functional groups (-Cl, -NO₂, OCH₃, -Br, CH₃, -OH). All compounds exhibited little action against Gram-negative microbes and strong activity against Gram-positive bacteria. Several compounds also showed modest antifungal potency.

Conclusions: Schiff base-modified benzimidazole derivatives represent promising antimicrobial agents, with selective efficacy towards Gram-positive organisms and potential as sustainable drug candidates.
