摘要：
Eleven new depsides-thielavins W-Z (1-4) and thielavins Z(1)-Z(7) (5-11)-and also four known thielavins-A, H, J, and K (12-15)-were isolated from the ethyl acetate extract of a marine-derived fungal strain Thielavia sp UST030930-004. All of these compounds were evaluated for antifouling activity against cyprids of the barnacle Balanus (=Amphibalanus) amphitrite. The results showed that compounds 1-3 and 6-13 were active, with EC50 values ranging from 2.95 +/- 0.59 to 69.19 +/- 9.51 mu M, respectively. The inhibitive effect of compounds 1-3 and 7 was reversible. This is the first description of the antifouling activity of thielavins against barnacle cyprids.
