Cortistatin A was isolated together with structurally related molecules from the sponge Corticium simplex. It shows potent anti-angiogenetic activity with a high selectivity towards several human and murine cancer cell lines. The focal step of the synthesis is a highly stereoselective aza-Prins cyclization to complete the steroid-like carbon framework (GH).
