S. Kosemura et al., CITREOANTHRASTEROID, A NEW METABOLITE OF A HYBRID STRAIN KO-0011 DERIVED FROM PENICILLIUM CITREO-VIRIDE-B IFO-6200 AND IFO-4692, Tetrahedron letters, 36(41), 1995, pp. 7481-7482
A sterol with an aromatized B ring, citreoanthrasteroid, has been isol
ated from the mycelium of a hybrid strain KO 0011 derived from Penicil
lium citreo-viride B. IFO 6200 and 4692. Its stereostructure has also
been elucidated on the basis of its spectral data and some chemical ev
idence.
