General description

Chemical structure: macrolide

Application

Bafilomycin A1 has been used:
  • as an autophagy inhibitor to study its effects on hepatic steatosis in human hepatocytes
  • as a vacuolar-type H+ -ATPase inhibitor to study its effects on the cell viability, percentage of PI-positive cells, and glucose-stimulated insulin secretion (GSIS) in mice INS-1 cells
  • as a vacuolar-type H+ -ATPase inhibitor to study its effects on tau degradation in human SH-SY5Y cells

Biochem/physiol Actions

A specific inhibitor of vacuolar type H+-ATPase (V-ATPase) in animal cells, plant cells and microorganisms.
Bafilomycin A1 inhibits autophagosome-lysosome fusion and autolysosome acidification, the steps involved in the autophagic process that is required for maintaining functional autophagic flux and cellular homeostasis.

Although biotherapeutics have vast potential for treating brain disorders, their use has been limited due to low exposure across the blood-brain barrier (BBB). We report that by manipulating the binding mode of an antibody fragment to the transferrin receptor (TfR)

Bafilomycin A1 is known as a strong inhibitor of the vacuolar type H(+)-ATPase in vitro, whereas other type ATPases, e.g. F1,F0-ATPase, are not affected by this antibiotic (Bowman, E.M., Siebers, A., and Altendorf, K. (1988) Proc. Natl. Acad. Sci. U.S.A.

The vacuolar H+-ATPases (V-ATPases) are conserved ATP-dependent proton pumps that acidify intracellular compartments in eukaryotic cells. The role of Cpvma1, a V-ATPase catalytic subunit A of Cryphonectria parasitica, was investigated by generating cpvma1-overexpressing and cpvma1-silenced strains. The mutant strains were

Autophagy, 11(8), 1437-1438 (2015-07-15)
Autophagosome-lysosome fusion and autolysosome acidification constitute late steps in the autophagic process necessary to maintain functional autophagic flux and cellular homeostasis. Both of these steps are disrupted by the V-ATPase inhibitor bafilomycin A1, but the mechanisms potentially linking them are
