Angiogenesis is a critical step for the tumor therapy. Many angiogenic factors are involved in the tumor angiogenesis. In the course of our screening for inhibitors of angiogenin secretion, one of angiogenic factors, we have isolated a new terrein glucoside (1) and terrein (2) from the fermentation broth of fungal strain Aspergillus sp. PF1381. The structure and absolute stereochemistry of 1 was determined to be (4S,5R)-5-[(alpha-D-glucopyranosyl)oxy]-4-hydroxy-3-(E-1-propenyl)-2-cyclopenten-1-one on the basis of spectral and enzymatic analyses. Compounds 1 and 2 equally inhibited angiogenin secretion from androgen-dependent prostate cancer cells, LNCaP-CR, with IC50 values of 13 microM. However, both compounds did not affect VEGF secretion, another angiogenic factor. Furthermore, both compounds inhibited tube formation of human umbilical vein endothelial cells (HUVEC). These results suggested that 1 and 2 act as angiogenesis inhibitors through the inhibition of angiogenin secretion.
