描述 | Bafilomycin A1, a macrolide antibiotic, is a potent and selective inhibitor of V-type H+-ATPase, and could disrupt pH regulation[1][2]. Bafilomycin A1 also showed moderate inhibition on ElE2 ATPases like K+-dependent (Kdp) ATPase from Escherichia coli, the Na+,K+-ATPase from ox brain, and the Ca2+-ATPase from sarcoplasmic reticulum, but F1Fo ATPases from bacteria and mitochondria are not affected by Bafilomycin A1[1]. Bafilomycin A1 can disrupt both autophagosome-lysosome fusion and autolysosome acidification constitute late steps in the autophagic process necessary to maintain functional autophagic flux and cellular homeostasis. Bafilomycin A1 induced a significant increase in cytosolic calcium concentration and disrupted Ca-P60A/SERCA-mediated fusion[3]. | ||
作用机制 | Bafilomycin A1 disrupts autophagic flux by independently inhibiting V-ATPase-dependent acidification and Ca-P60A/SERCA-dependent autophagosome-lysosome fusion.[3] |
