Apicidin is a histone deacetylase inhibitor with anti-invasive and anti-angiogenic potentials.
Apicidin has been identified as a histone deacetylase (HDAC) inhibitor. Since HDAC inhibitors are emerging as an exciting new class of potential anti-cancer agents, in the present study, we have examined the inhibitory effect of apicidin on cancer invasion and angiogenesis. Apicidin induced di- and tri-acetylated forms of histone H4 and the morphological alteration in v-ras-transformed mouse fibroblast NIH3T3 cells. Apicidin dramatically inhibited the invasion of v-ras-NIH3T3 and human melanoma A2058 cells and it could be associated with its ability to regulate the activities of matrix metalloproteinases. Interestingly, apicidin strongly inhibited the formation of new vessels on chorioallantoic membrane and the tube formation of ECV304 human vascular endothelial cells. This is the first report to show the anti-angiogenic potential of apicidin and it could be developed as a new type of anti-cancer drug.
