Y. Fujii et al., 12-MEMBERED LACTONES PRODUCED BY CLADOSPORIUM-TENUISSIMUM AND THE PLANT-GROWTH RETARDANT ACTIVITY OF CLADOSPOLIDE-B, Phytochemistry, 40(5), 1995, pp. 1443-1446
Three 12-membered macrolides were isolated from a culture filtrate of
the fungus, Cladosporium tenuissimum. Two were identified as cladospol
ides A and B, and one as a new cladospolide, which was named cladospol
ide C. Cladospolide C is a diastereomer of cladospolide A. Cladospolid
e B was inhibitory to shoot elongation of rice seedlings (Oryza sativa
L.) without damaging the cells. Its activity was investigated in rela
tion to gibberellin biosynthesis.
