Brefeldin A Chemical Properties,Uses,Production
Description
Brefeldin A (20350-15-6) is a specific inhibitor of protein translocation from endoplasmic reticulum to Golgi. Induces apoptosis. Brefeldin A activates sphingomyelin metabolism. Cell permeable.
Chemical Properties
White Powder
Uses
A macrolide isolated from Penicillium brefeldianum. It affects the vesticular transport of the Golgi apparatus and induces DNA fragmentation which leads to apoptosis
Uses
Brefeldin A is a potent inhibitor of cell growth first described in 1958, then independently rediscovered by several groups as a potent active in a broad range of bioassays. Brefeldin has antiviral, antibiotic, antifungal, antitumour and herbicidal activity. Early studies on the mode of action of brefeldin identified inhibition of protein and nucleic acid synthesis by disruption of the Golgi apparatus. The precise molecular target is a subset of Sec7-type GTP exchange factors (GEFs) that activate a small GTPase, Arf1p, an integral component of protein trafficking and signalling.
Uses
Brefeldin A (BFA) is a natural fungal metabolite which has been used extensively to study intracellular transport by vesicles or endosomes. Early studies demonstrated that BFA reversibly interferes with protein trafficking and secretion mediated by the Golgi apparatus and endoplasmic reticulum. BFA directly and reversibly inhibits Sec7 domain-containing guanine-exchange factors which are necessary for ADP-ribosylation factor activation associated with vesicular transport (IC50 = ~10 μM). BFA is used to study endosomal trafficking and function in cells of plants as well as those of fungi, invertebrates, and vertebrates.
Definition
ChEBI: A metabolite from Penicillium brefeldianum that exhibits a wide range of antibiotic activity.
General Description
Specifically and reversibly blocks translocation of proteins from the endoplasmic reticulum (ER) to the Golgi apparatus without affecting endocytosis or lysosome function. Inhibitor of HDL-mediated cholesterol efflux. Causes disassembly of the Golgi complex and ER swelling in a variety of mammalian cell lines at <40 ng/ml. Blocks binding of ADP-ribosylation factor to the Golgi and inhibits the GDP-GTP exchange. Inhibits the activity of BIG1 and BIG2, the guanine-nucleotide exchange proteins for ADP-ribosylation factors. Also available as a 25 mM solution in DMSO (Cat. No. 500583).
Biological Activity
Reversible inhibitor of protein translocation from the endoplasmic reticulum (ER) to the Golgi apparatus. Blocks binding of ADP-ribosylation factor to the Golgi apparatus and inhibits GDP-GTP exchange.
Biochem/physiol Actions
Primary TargetBlocks translocation of proteins from the endoplasmic reticulum (ER) to the Golgi apparatus
storage
-20°C (desiccate)
Purification Methods
Brefeldin A was isolated from Penicillium brefeldianum and recrystallised from aqueous MeOH/EtOAc or MeOH. Its solubility in H2O is 0.6mg/mL, 10mg/mL in MeOH and 24.9mg/mL in EtOH. The O-acetate recrystallises from Et2O/pentane and has m 130-131o, [] D +17o (c 0.95, MeOH). [Sigg Helv Chim Acta 47 1401 1964, UV and IR: H.rri et al. Helv Chim Acta 46 1235 1963, total synthesis: Kitahara et al. Tetrahedron 3021 1979, X-ray : Weber et al. Helv Chim Acta 54 2763 1971, Beilstein 18 III/IV 1220.]
Background
Brefeldin A is a fungal metabolite demonstrated to reversibly interfere with anterograde transport from the endoplasmic reticulum to the Golgi apparatus. While initially isolated as an antibiotic, and does have a wide range of antibiotic activity, it is primarily used as a biological research tool for studying protein transport. Treatment leads to a rapid accumulation of proteins within the ER and collapse of the Golgi stacks. Treatment with BFA can also inhibit protein secretion and prolonged exposure can induce apoptosis. The main target of BFA appears to be ADP-ribosylation factor, which is responsible for association of coat protein to the Golgi membrane.
