Inhibition of endothelial cell functions by novel potential cancer chemopreventive agents

Endothelial cells (EC) play a major role in tumor-induced neovascularization and bridge the gap between a microtumor and growth factors such as nutrients and oxygen supply required for expansion. Immortalized human microvascular endothelial cells (HMEC-1) were utilized to assess anti-endothelial eff...

Description
Summary:Endothelial cells (EC) play a major role in tumor-induced neovascularization and bridge the gap between a microtumor and growth factors such as nutrients and oxygen supply required for expansion. Immortalized human microvascular endothelial cells (HMEC-1) were utilized to assess anti-endothelial effects of 10 novel potential cancer chemopreventive compounds from various sources that we have investigated previously in a human in vitro anti-angiogenic assay. These include the monoacylphloroglucinol isoaspidinol B, 1,2,5,7-tetrahydroxy-anthraquinone, peracetylated carnosic acid (PCA), isoxanthohumol, 2,2′,4′-trimethoxychalcone, 3′-bromo-2,4-dimethoxychalcone as well as four synthetic derivatives of lunularic acid, a bibenzyl found in mosses [Int. J. Cancer Prev. 1 (2004) 47]. EC proliferation was inhibited with half-maximal inhibitory concentrations from 0.3 to 49.6μM, whereas EC migration was affected by most compounds at sub-micromolar concentrations. PCA and the bibenzyl derivative EC 1004 potently prevented differentiation of HMEC-1 into tubule-like structures. Overall, our data indicate that inhibition of endothelial cell function contributes to various extents to the chemopreventive or anti-angiogenic potential of these lead compounds.
