Hazard Information | Back Directory | [Chemical Properties]
white to off-white powder | [Uses]
A macrolide antibiotic and potent and selective inhibitor of vacuolar-type (v-type) H+ ATPase | [Uses]
Bafilomycin A1 is a member of a potent family of macrocyclic lactones with broad spectrum biological activity, including activity against bacteria, yeast, fungi, nematodes, insects and tumor cell lines. Bafilomycin A1 is an inhibitor of vacuolar-type ATPase. | [Uses]
Bafilomycin A1 is a member of a potent family of macrocyclic lactones with broad spectrum biological activity, including activity against bacteria, yeast, fungi, nematodes, insects and tumour cell lines. Bafilomycin A1 is an inhibitor of vacuolar-type ATPase. | [Definition]
ChEBI: The most used of the bafilomycins, a family of toxic macrolide antibiotics derived from Streptomyces griseus. | [Biological Activity]
Highly potent, selective inhibitor of vacuolar H + -ATPases (IC 50 = 500 pM as measured in chromaffin granule membranes). Selective over other ATP hydrolyzing enzymes such as F-ATPases, Ca 2+ -ATPases, Na + /K + -ATPases and plasma membrane H + -ATPases. | [Description]
Bafilomycin A1 is a fungal metabolite that has been found in Streptomyces and has diverse biological activities.1,2,3,4,5 It is an inhibitor of vacuolar H+-ATPases (V-ATPases; Ki = 0.5 nM in N. crassa vacuolar membranes) and is greater than 1,000-fold selective for V-ATPases over Na+/K+-, Ca2+-, and H+-ATPases.1,4 Bafilomycin A1 (100 nM) inhibits autophagosome maturation and protein degradation in H-4-II-E cells.2 It inhibits chloroquine-induced apoptosis in primary cerebellar granule neurons (CGNs) but not chloroquine-induced inhibition of macroautophagy.3 Bafilomycin A1 (100 nM) reduces viral yield in the culture supernatant of Vero E6 and Huh7 cells, as well as HEK293T cells expressing human angiotensin-converting enzyme 2 (ACE2), infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).5 It also reduces lung RNA copy numbers and viral pneumonia in ACE2 transgenic mice infected with SARS-CoV-2 when administered at a dose of 0.1 mg/kg. | [General Description]
A macrolide antibiotic that acts as a specific inhibitor of vacuolar-type H+-ATPase (V-type; Ki = 500 pM). A valuable tool for distinguishing among different types of ATPases. Blocks lysosomal cholesterol trafficking in macrophages and is known to interfere with pH regulation in brain cells. Exhibits cytotoxic effects on a number of cell lines in a cell viability assay. Reported to selectively inhibit β-secretase, an enzyme involved in the processing of amyloid precursor protein (APP). The InSolution format with a purity of ≥97% by HPLC in 90% DMSO is also available (Cat. No. 508409). | [Biochem/physiol Actions]
