Bafilomycin A1 is a macrolide antibiotic that selectively inhibits vacuolar-type (v-type) H+ ATPase. The compound can inhibit E1E2 ATPases from sarcoplasmic reticulum, E. coli, and ox brain versus F1F0 ATPases found in bacteria and mitochondria. It blocks pH regulation in brain cells. Additionally, Bafilomycin A1 prevents lysosomal cholesterol trafficking in macrophages and can be used to distinguish different types of ATPases.
