The biosynthetic reduction of the polyketide chain may prevent the formation of aromatic products. Instead, several lactones are formed. For example, a series of bio-active pentaketide metabolites containing a ten-membered ring have been isolated. These include the diplodialides e.g. diplodialide A, 4.73) from Diplodia pinea, the pyrenolides e.g. pyrenolide A, 4.74) from Pyrenophora teres and the cephalosporolides e.g. cephalosporolide B, 4.75) from Cephalosporium aphidi-cola. An unusual dimeric pentaketide, thiobiscephalosporolide A (in which the two lactones are held together by a sulfur), has also been obtained from...
