Design, Synthesis, and Antiangiogenic Effects of a Series of Potent Novel Fumagillin Analogues

Abstract

A series of fumagillin analogues containing the C6-substituted cinnamoyl moiety were designed, synthesized, and evaluated for antiangiogenic activity. Among them, 4-hydroxyethoxy-cinnamoyl fumagillol (4a) and 4-hydroxyethoxy-3,5-dimethoxycinnamoyl fumagillol (4d) exhibited more potent anti-proliferation activity in CPAE and HUVEC cells with low cytotoxicity in vitro. These compounds are presently under further pharmacological evaluation studies.
