Rugulosin (+ form) (CAS 23537-16-8)

Rugulosin, particularly its (+) form, has garnered significant interest in scientific research due to its diverse biological activities and potential applications in chemical biology and drug discovery. This compound, isolated from various fungi species, exhibits potent inhibitory effects on the enzyme squalene epoxidase (SE), a key enzyme in the biosynthesis of ergosterol, an essential component of fungal cell membranes. Rugulosin′s mechanism of action involves the specific binding to the active site of squalene epoxidase, thereby inhibiting its enzymatic activity and disrupting ergosterol synthesis. Research has explored the structural features of rugulosin and its binding interactions with squalene epoxidase, providing insights into its mechanism of action and potential for structure-based drug design. Additionally, rugulosin has shown promising antifungal activity against a wide range of fungal pathogens, including both yeast and filamentous fungi, suggesting its potential as a lead compound for the development of novel antifungal agents. Furthermore, studies have investigated the potential of rugulosin derivatives and analogs as scaffolds for the development of new antifungal drugs with improved potency and pharmacological properties. Overall, rugulosin represents a valuable tool in chemical biology research, offering insights into fungal membrane biology and serving as a potential starting point for the development of new antifungal therapies.
