Common NameAureobasidin A
DescriptionAureobasidin A is a natural cyclic peptide belonging to the class of antifungal metabolites. Its chemical structure features a unique cyclic arrangement that is crucial for its biological activity, particularly its inhibition of inositolphosphorylceramide (IPC) synthase, an enzyme involved in sphingolipid biosynthesis. Aureobasidin A exhibits antifungal properties by targeting the sphingolipid biosynthetic pathway, which is essential for fungal cell membrane integrity and function. The compound has been shown to affect various pathways, including the inhibition of IPC synthase, leading to impaired ergosterol biosynthesis, which is critical for fungal survival. Studies have identified candidate clones resistant to aureobasidin A, including transcription factor families such as DOF, NAC, ERF, and BES1 (PMID:41008558 ). Additionally, the combination of aureobasidin A with amphotericin B has demonstrated enhanced efficacy against cryptococcal meningitis in mice compared to standard therapies (PMID:38225460 ). Moreover, aureobasidin A has been implicated in structural and functional alterations in clinical resistant strains of Candida spp. (PMID:37998920 ). Overall, aureobasidin A plays a significant role in the modulation of fungal cell pathways, particularly in the context of drug resistance and antifungal activity.
