抄録

Our search for new 3-hydroxyfusicoccins structurally related to cotylenin A from a culture of <I>Phomopsis amygdali</I> Niigata 2-A resulted in the isolation of novel 3-hydroxy fusicoccins, called fusicoccins R and S, and the fusicoccin S aglycon, called phomopsiol, together with known 3α-hydroxyfusicoccin J. The structure of phomopsiol was identified as that of <I>O</I>-demethyl-3-epicotylenol based on spectroscopic evidence. The structures of fusicoccins R and S were also determined to be those of 3′-deacetyl-3α-hydroxyfusicoccin A and 3β-hydroxy-3-epifusicoccin H. The lettuce seed germination-stimulating activity of fusicoccins R and S, phomopsiol and 3α-hydroxyfusicoccin J was examined in the presence of ABA; fusicoccin R and 3α-hydroxyfusicoccin J were highly active, while fusicoccin S and phomopsiol were inactive. The possible biosynthetic relationships among these novel fusicoccins having a 3α- or 3β-hydroxy group in their diterpene moiety are briefly discussed.
