Brefeldin A is a lactone antibiotic and ATPase inhibitor for protein transport with IC50 of 0.2 μM in HCT 116 cells, induces cancer cell differentiation … Brefeldin A is a lactone antiviral produced by the fungus Penicillium brefeldianum. Brefeldin A inhibits protein transport from the endoplasmic reticulum to the golgi complex indirectly by preventing association of COP-I coat to the Golgi membrane. Brefeldin A was initially isolated with hopes to become an antiviral … See more The compound gets its name from a species of anamorph fungus of the Penicillium genus known as Eupenicillium brefeldianum, though it is found in a variety of species that span several genera.

WebApr 22, 1999 · The two most widely used reagents are monensin and brefeldin A (BFA). These reagents differ somewhat in their mode of action, which might explain their different effects. Monensin is an inhibitor of trans-Golgi function, while BFA inhibits protein transport between the endoplasmic reticulum (ER) and the Golgi. WebBrefeldin A (BFA) is relatively non-selective inhibiting at least three targets in human cells, Golgi brefeldin A resistance factor 1 (GBF1), brefeldin A inhibited guanine … most affordable islands to visit

WebJan 23, 2007 · Brefeldin A-inhibited guanine nucleotide-exchange proteins (BIG) 1 and BIG2 activate human ADP-ribosylation factors (ARF) 1 and ARF3 by catalyzing the replacement of ARF-bound GDP with GTP to regulate Golgi vesicular transport. We show here a requirement for BIG1 (but not BIG2) in glycosylation and function of β1. WebBrefeldin A (BFA) is a fungal macrocyclic lactone and a potent, reversible inhibitor of intracellular vesicle formation and protein trafficking between the endoplasmic reticulum (ER) and the Golgi apparatus [1]. BFA and its analogs are promising inhibitors in drug development due to a number of key features such as apoptosis‑inducing ...
