Dg. Nagle et al., A new indanone from the marine cyanobacterium Lyngbya majuscula that inhibits hypoxia-induced activation of the VEGF promoter in Hep3B cells, J NAT PROD, 63(10), 2000, pp. 1431-1433
A new indanone (1) has been isolated from the filamentous marine cyanobacte
rium Lyngbya majuscula, and its structure determined spectroscopically. Vas
cular endothelial growth factor (VEGF) is an important regulator of tumor a
ngiogenesis. Compound 1 inhibits hypoxia-induced activation of the VEGF gen
e promoter in Hep3B human liver tumor cells, in vitro.
