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.

Description

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[1].
In Vitro

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].

Western Blot Analysis[1]

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.

Immunofluorescence[1]

Cell Line: A549 cells
Concentration: 0.2 μM
Incubation Time: 6 h
Result: Abolished TGF-β-induced Smad2/3 nuclear translocation.

Cell Migration Assay [1]

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
