• Description: Bafilomycin A1 is a fungal 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.
• 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. A macrolide antibiotic and potent and selective inhibitor of vacuolar-type (v-type) H+ ATPase Bafilomycin A1 is a specific potent inhibitor of vacuolar ATPases.It is used as an antibacterial, antifungal, antineoplastic and an immunosuppressive. It prevents maturation of autophagic vacuoles by inhibiting fusion between autophagosomes and lysosomes and is a macrolide antibiotic and potent and selective inhibitor of vacuolar-type H+ ATPase (V-ATPase).
