Phanerosporicacid is a fungal secondary metabolite originally isolated from P. chrysosporum that has antibacterial activity against B. cereus, B. subtilis, and E. coli and antifungal activity against S. cerevisiae, A. niger, O. ulmi, U. maydis, C. cucmerinum, C. cladosporioides, and B. cinerea.1 It has been used in the synthesis of macrolide derivatives.References1.
