Additional Information:

Bafilomycin A1 is a macrolide antibiotic derived from Streptomyces griseus which is a potent and selective inhibitor of vacuolar H+-ATPases with an IC50 = 0.6 – 1.5 nM (1,2). This compound inhibits autophagy via the disruption of fusion between autophagosomes and lysosomes (3).
