Evaluation of antiangiogenic activity of azumamides by the in vitro vascular organization model using mouse induced pluripotent stem (iPS) cells.

ABSTRACT

Evaluation of antiangiogenic activity of marine sponge derived azumamides by the in vitro vascular organization model using mouse induced pluripotent stem (iPS) cells was carried out. Azumamide E (5) strongly inhibited in vitro angiogenesis from iPS cells at 1.9microM while azumamide A (1) showed only weak inhibition at 19microM. These results were well correlated with HDAC inhibitory activity of these compounds, revealing the prospect of azumamides as the probe molecules useful for stem cell chemical biology.
