Isolation and structure elucidation of aza-sesquiterpenoids of protoilludane origin formed by shaken cultures of the fungus Clavicorona divaricata / G. Nasini, A. Arnone, A. Bava, L. Musso. - In: PHYTOCHEMISTRY LETTERS. - ISSN 1874-3900. - 5:1(2012 Jan), pp. 224-227.
Abstract:
Two novel sesquiterpenes of protoilludane origin, the alkaloids divaricatine C and D, have been isolated
from MPGB shaken cultures of the fungus Clavicorona divaricata (Basidiomycetes). Their structures were
elucidated by means of NMR studies and chemical correlations. The metabolites were weakly active
against bacteria and inhibited the germination of the water cress Lepidium sativum. A possible
mechanism of their formation from the protoilludane tsugicoline A (2) is suggested.
