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). Colletodiol inhibits influenza A viral replication in HeLa-IAV-Luc cells.

Colletodiol is a metabolite of Chaetomium funicola and an inhibitor of influenza A virus. Colletodiol can be used to synthesize Grahamimycin A and colletol.
