This invention introduces a novel medicinal compound based on a heterocyclic system containing azo functionality, synthesized via azo-coupling with 4-amino-benzimidazole. It demonstrates significant efficacy against methicillin-resistant Staphylococcus aureus (MRSA) with a minimum inhibitory concentration of 12 µM, coupled with a low cytotoxic profile (IC50 of 47 µM) to mammalian cells. The compound's unique structure provides a new biological activity profile unexplored by prior art, positioning it as a promising candidate for addressing antibiotic resistance.
