Bafilomycin A1 (solution)

Bafilomycin A1 is a bacterial metabolite that has been found in Streptomyces and has diverse biological activities. 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. Bafilomycin A1 (100 nM) inhibits autophagosome maturation and protein degradation in H-4-II-E cells. It inhibits chloroquine-induced apoptosis in primary cerebellar granule neurons (CGNs) but not chloroquine-induced inhibition of macroautophagy. 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). 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.
