Bafilomycin D is a potent inhibitor of vacuolar H+ ATPases (V-ATPases) with IC50 value of approximately 2 nM for the V-ATPase from the fungus N. crassa [1].

Ion pumps use the energy provided by the hydrolysis of ATP to energize ion-transport processes across cell membranes. ATPases can be distinguished to P-type, F-type and V-type ATPases. P-type ATPases have a phosphorylated transitional stage, F-type ATPases are primarily used in ATP synthesis, and V-type ATPases are genetically and functionally related to F-ATPases but function only in ATP breakdown [1].

The bafilomycins are fungal plecomacrolide class macrolide antibiotics isolated from the culture medium of Streptomyces sp. and are also high-affinity inhibitors of V-ATPases and can be used to study specifically the function of this type of ATPase. They inhibited the growth of Gram-positive bacteria and fungi. Bafilomycin C1 inhibited the enzymatic activity of the Na+, K+-ATPase with Ki value of 11 μmol/l and showed anthelmintic activity against Caenorhabditis elegans [1][2].
