Use of Pentachloropseudilin

Pentachloropseudilin (Antibiotic A 15104 Y; PClP) is a reversible and allosteric potent inhibitor of Myo1s (class 1 myosins) with IC50s range from 1 to 5 μM for mammalian class-1 myosins and greater than 90 μM for class-2 and class-5 myosins. Pentachloropseudilin is a potent inhibitor of transforming growth factor-β (TGF-β)-stimulated signaling, with an IC50 of 0.1 to 0.2 μM for TGF-β[1][2].

In Vitro	Pentachloropseudilin (PClP) inhibits TGF-β-stimulated Smad2/3 phosphorylation and plasminogen activator inhibitor-1 (PAI-1) promoter activation with an IC50 of 0.1 μM in target cells (A549, HepG2, and Mv1Lu cells)[1]. Pentachloropseudilin attenuates TGF-β-stimulated expression of vimentin, N-cadherin, and fibronectin and, thus, blocks TGF-β-induced epithelial to mesenchymal transition (EMT) in these cells. Pentachloropseudilin (0.05 to 1 μΜ; 0-6 hours) pretreatment inhibits TGF-β-mediated (50 or 100 pM) increases in p-Smad2/3 expression to 47% (Mv1Lu) and 79% (A549), respectively[1]. Pentachloropseudilin (0.2 μM) suppresses TGF-β-stimulated cellular responses by attenuating cell-surface expression of the type II TGF-β receptor through accelerating caveolae-mediated internalization followed by primarily lysosome-dependent degradation of the receptor, as demonstrated by sucrose density gradient analysis and immune fluorescence staining[1]. Pentachloropseudilin (200 μM; 24 hours) exhibits and altered cell viability in HUVECs[2].
