Bryostatin 2 is a macrocyclic lactone and antagonist of phorbol ester action. It binds to and activates protein kinase C (PKC) creating a transcriptional response similar to phorbol esters.

ChEBI: Bryostatin 2 is a member of the class of bryostatins that is bryostatin 1 in which the acetoxy group has been replaced by a hydroxy group. It has a role as a protein kinase C agonist, an antineoplastic agent and a marine metabolite. It is a member of bryostatins, a cyclic hemiketal, an enoate ester, a methyl ester, an organic heterotetracyclic compound and a secondary alcohol.

Bryostatin 2 is potent protein kinase C activator (Ki = 5.9 nM) and an antagonist to phorbol ester tumor promoter 12-0-tetradecanoylphorbol-13-acetate (TPA). Bryostatin 2 exhibits antineoplastic activity against the murine P388 lymphocytic leukemia and human U937 cells.
