The cortistatins are a group of steroidal alkaloids first isolated in 2006 from the marine sponge Corticium simplex.^[1] The cortistatins inhibit proliferation of human umbilical vein endothelial cells (HUVECs) with high selectivity, with cortistatin A being the most potent compound in the class.^[2]

The unique chemical structure and potent biological activity of these compounds have stimulated interest in their total synthesis and further biological evaluation.^[3]^[4]
