Abstract

Angiogenesis is regulated by various factors. In particular, VEGF and basic FGF are of much importance. We found that 8-(3-oxo-4,5,6-trihydroxy-3h-xanthen-9-yl)-1-naphthoic acid inhibited the binding of VEGF to KDR/Flk-1 (VEGF receptor-2) or Flt-1 (VEGF receptor-1) and that it inhibited the MAPK phosphorylation in HUVEC induced by VEGF or basic FGF but not by EGF. 8-(3-oxo-4,5,6-trihydroxy-3h-xanthen-9-yl)-1-naphthoic acid might be used as an inhibitor of VEGF and basic FGF signal transduction.
