Viridin

Chemical compound: furanosteroid

Viridin is an antifungal metabolite of Gliocladium virens that was first reported in 1945. Belonging to a class of molecules known as furanosteroids, it has a characteristic highly strained electrophilic furan ring fused between C-4 and C-6 of the steroid framework. Members of this family, including wortmannin, are known to be potent, irreversible covalent inhibitors of phosphoinositide 3-kinases (PI3Ks).
