Fibraurin is primarily used in biomedical research for its antimicrobial and antifungal properties. It shows activity against a range of Gram-positive bacteria and certain fungal strains, making it a candidate for development in anti-infective therapies. Its mechanism involves interference with microbial cell wall synthesis, which enhances its potential as a lead compound in novel antibiotic design. Additionally, Fibraurin has been investigated for its immunosuppressive effects, suggesting possible applications in modulating immune responses, particularly in autoimmune diseases or organ transplantation. Due to its complex structure, it is also studied in the context of natural product synthesis and structure-activity relationship modeling.
