Colletodiol
Colletodiol is a fungal metabolite that has been found in D. grovesii and has immunosuppressant and antiviral activities. It inhibits concanavalin A- or LPS-induced proliferation of isolated mouse splenocytes (IC50s=12 and 5 μg/mL, respectively).1 Colletodiol inhibits influenza A viral replication in HeLa-IAV-Luc cells.
