靶点
  • ATPase

    ATPase (HCT 116), IC50:0.2 μM

描述 Brefeldin A is a fungal lactone antibiotic produced by Penicillium brefeldianum usually used as a protein trafficking/secretion inhibitor in mammalian and other eukaryotic cells, without significant effect on protein synthesis. The main target of Brefeldin A may be Arf1, which is important to formation of protein transport vesicles[1][2][3]. Brefeldin A could induce the rapid redistribution of the ll0-kD protein and the movement of Golgi membrane into the ER within 15min at 2μg/ml in semipermeable cells[4]. Brefeldin A could induce a wide variety of human cancer cells to differentiation and apoptosis. It exhibited cytotoxicity to HCT 116 cells with IC50 value of 0.2μM, as well as induced DNA fragmentation and apoptotic morphological changes with IC50 values of 0.11 and 0.36 μM, respectively[5]. Brefeldin A combined with L755507 could improve the HDR efficiency, and exhibit enhanced insertion efficiency by 2-fold, with maximal effect at 0.1 μM[6].
作用机制 Brefeldin A inhibits protein trafficking and secretion by interfering with the function of the Golgi apparatus, which may due to the disruption of transport vesicle formation dependent on the assembly of the COPI coat by Arf1-GTP.[1][2][3]

COS7 cells 5 µg/ml 50 min To investigate the effect of BFA treatment on Golgi structure, it was found that BFA treatment causes Golgi dispersion. J Cell Biol. 2024 Dec 2;223(12):e202311189.
HeLa cells 5 µg/ml 1 hour To investigate the effect of VPS13B loss on Golgi structure, it was found that the absence of VPS13B delays Golgi recovery. J Cell Biol. 2024 Dec 2;223(12):e202311189.
porcine intestinal epithelial cells (IPEC-1) 0.1 µM 12 h To investigate the effect of BFA on apoptosis and intestinal barrier function in IPEC-1 cells, results showed that BFA treatment led to increased apoptosis and upregulation of proteins involved in ER stress signaling, while inducing dysfunction in the intestinal epithelial barrier.

IC21 murine macrophages 5 µg/ml 1 hour Brefeldin A was used to block protein secretion from the ER to the Golgi apparatus. The experimental results showed that Brefeldin A treatment did not lead to the accumulation of IL-36γ within the cells, indicating that IL-36γ is not secreted through the conventional secretory pathway. Front Immunol. 2022 Aug 18;13:979749.
