  • Bryostatin 1 binds to and activates protein kinase C, but its biological effects differ greatly from those induced by other protein kinase C activators. Bryostatin 1 fails to mimic many effects caused by PMA and actually blocks some PMA-induced response in a variety of cells and tissues. Kraft, A.S., et al. "Bryostatin, an activator of the calcium phospholipid-dependent protein kinase, blocks phorbol ester-induced differentiation of human promyelocytic leukemia cells HL-60." Proc. Natl. Acad. Sci. USA 83: 1334-1338 (1986). Sako, T., et al. "Partial parallelism and partial blockade by bryostatin 1 of effects of phorbol ester tumor promoters on primary mouse epidermal cells." Cancer Res. 47: 5445-5450 (1987). Dell'Aquila, M.L., et al. "Inhibition by bryostatin 1 of the phorbol ester-induced blockage of differentiation in hexamethylene bisacetamide-treated Friend erythroleukemia cells." Cancer Res. 47: 6006-6009 (1987). Hess, A.D., et al. "Activation of human T lymphocytes by bryostatin." J. Immunol. 141: 3263-3269 (1988).
  • The true affinity of bryostatin 1 for PDBu binding site on PKC appears to be in the low picomolar range or lower. de Vries, D.J., et al. "Demonstration of sub-nanomolar affinity of bryostatin 1 for the phorbol ester receptor in rat brain." Biochem. Pharmacol. 37: 4069-4073 (1988).
  • Please request Technical Note #1 for additional information.
  • Please note: The correct molecular weight for bryostatin I is 905.04. Perhaps the M.W. 887 error found in other catalogs arises because the original publication describing bryostatin I mentions a mass spectrum peak at 887, but apparently that peak resulted from the loss of one water molecule during the mass spectral process.
