Aureusimine B is primarily studied for its potential antimicrobial properties, particularly against Gram-positive bacteria. It has shown inhibitory effects in laboratory settings, making it a candidate for development in anti-infective therapies. Its unique structure may interfere with bacterial protein synthesis or cell wall integrity, though the exact mechanism remains under investigation. Due to its natural origin and selective activity, it is also of interest in the design of novel antibiotics aimed at overcoming drug resistance. Research is ongoing to evaluate its efficacy, stability, and suitability for pharmaceutical use.
