A New Indanone from the Marine Cyanobacterium <i>Lyngbya m</i><i>ajuscula</i> That Inhibits Hypoxia-Induced Activation of the VEGF Promoter in Hep3B Cells

Abstract

A new indanone (1) has been isolated from the filamentous marine cyanobacterium Lyngbya majuscula, and its structure determined spectroscopically. Vascular endothelial growth factor (VEGF) is an important regulator of tumor angiogenesis. Compound 1 inhibits hypoxia-induced activation of the VEGF gene promoter in Hep3B human liver tumor cells, in vitro.
