Common NameBafilomycin A1
DescriptionBafilomycin A1 is a macrolide antibiotic belonging to the class of v-ATPase inhibitors. Its chemical structure features a complex polyene backbone with multiple hydroxyl and methoxy groups, contributing to its biological activity. Bafilomycin A1 primarily functions by inhibiting the vacuolar ATPase (v-ATPase), which is crucial for acidifying intracellular compartments, including lysosomes. This inhibition disrupts autophagic processes, as evidenced by studies showing that Bafilomycin A1 enhances the pro-apoptotic activity of chemotherapeutic agents like CPX by blocking autophagy in K562 cells (PMID:41049452 ). Additionally, it has been shown to reverse cisplatin resistance by affecting autophagy-related markers (PMID:41049434 ). The compound also influences exocytotic mechanisms in a calcium-dependent manner (PMID:41015092 ) and prevents degradation of c-MYC when combined with other agents (PMID:41014667 ). Its role in late-stage autophagy inhibition is further supported by the accumulation of specific autophagy markers (PMID:40964235 ). Furthermore, Bafilomycin A1 has implications in lysosomal degradation pathways, as indicated by its inhibitory effects on Tau degradation (PMID:40963907 ) and its role in restricting viral replication (PMID:40920489 ).
