Pentachloropseudilin (Synonyms: Antibiotic A 15104 Y; PClP)

Pentachloropseudilin (Antibiotic A 15104 Y; PClP) 是一种可逆的、变构有效的肌球蛋白 (Myo1s) 抑制剂，对 Myo1s 的 IC50 范围为 1 至 5 μM，对于 2 类和 5 类肌球蛋白，IC50 范围 > 90 μM。Pentachloropseudilin 是转化生长因子-β (TGF-β) 刺激的信号传导的有效抑制剂，对 TGF-β 的 IC50 值为 0.1-0.2 μM。

生物活性

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].

体外研究
(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].
