Pentabromopseudilin
Based on 1 publication(s) in Google Scholar
Pentabromopseudilin (PBrP) is a marine antibiotic isolated from the marine bacteria Pseudomonas bromoutilis and Alteromonas luteoviolaceus. PBrP exhibits antimicrobial, anti-tumour and phytotoxic activities. PBrP is a reversible and allosteric inhibitor of myosin Va (MyoVa). PBrP also is a potent inhibitor of transforming growth factor-β (TGF-β) activity. PBrP can be used for the research of fibrotic diseases and cancer.

Biological Activity
Pentabromopseudilin (PBrP) (0.01-1 μM, 6 h) prevents TGF-β-induced Smad protein phosphorylation and nuclear translocation[1].
PBrP (0.5 μM, 6 h) inhibits TGF-β-stimulated transcriptional responses[1].
PBrP (0-1 μM, 6 h) inhibits TGF-β-induced EMT in A549 cells[1].
PBrP (0.2 μM, 20 h) suppresses TGF-β-induced cell migration[1].
PBrP (0.01-1 μM, 6 h) blocks TGF-β signalling by enhancing degradation of TβRII[1].
PBrP (0.5 μM, 0, 1, 3 h) blocks TGF-β signalling by enhancing degradation of TβRII via caveolae[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:Mv1Lu, A549, Clone 9 and HepG2 cells
-
Concentration:0.01-1 μM (Mv1Lu, A549, Clone 9 and HepG2 cells); 0.5 μM (Mv1Lu, A549 and HepG2 cells)
-
Incubation Time:6 h (Mv1Lu, A549, Clone 9 and HepG2 cells); 0.5, 1, 2, 4, 6 h (Mv1Lu, A549 and HepG2 cells)
-
Result:Suppressed the TGF-β-stimulated Smad2/3 phosphorylation in a dose-dependent manner in these cell lines.
Prevented TGF-β induced the nuclear translocation of Smad2/3 and PBrP alone did not alter the localisation of Smad proteins.

Cell Line:A549 cells
-
Concentration:0.2 μM
-
Incubation Time:6 h
-
Result:Abolished TGF-β-induced Smad2/3 nuclear translocation.
-
Cell Line:A549 cells
-
Concentration:0.2 μM
-
Incubation Time:20 h
-
Result:Suppressed TGF-β-stimulated cell migration and did not close the wound.
