Six bryostatins were isolated from Japanese bryozoan by evaluating their binding to the C1B domain of protein kinase Cδ (PKCδ). Structure-activity studies of bryostatins 4, 10, and 14 suggested that the ester group at C20 was not necessary for binding to and activating PKCδ. These bryostatins showed significant anti-tumor-promoting activity in induction tests with the Epstein-Barr virus early antigen.
