Pentachloropseudilin (Antibiotic A-15104 Y; PClP) is a novel, potent and allosteric Myosin-1 (Myo1) inhibitor. Also inhibits transforming growth factor-β activity by accelerating cell-surface type II TGF-β receptor turnover.
| ln Vitro |
In target cells (A549, HepG2, and Mv1Lu cells), pentachloropsin (PClP) inhibits TGF-β-stimulated Smad2/3 phosphorylation and plasminogen activator inhibitor-1 (PAI-1) promoter activation; the IC50 value is 0.1 μM [1]. Pentachloropseudoprotein inhibited vimentin, N-cadherin, and fibronectin expression in response to TGF-β, preventing TGF-β-induced epithelial-mesenchymal transition (EMT) in these cells. The TGF-β-mediated (50 or 100 pM) increase in p-Smad2/3 expression was inhibited by pretreatment with pentachloropsin (0.05 to 1 μM; 0–6 hours) by 47% (Mv1Lu) and 79% (A549)[1]. By reducing the expression of type II TGF-β receptors on the cell surface and speeding up caveolae-mediated internalization, which is mainly followed by lysosome-dependent receptor degradation, pentachloropsin (0.2 μM) inhibits TGF-β. Sucrose density gradient analysis and immunofluorescence staining were used to examine cellular responses to stimulation [1]. In HUVEC, pentachloropsin (200 μM; 24 hours) shows and modifies cell viability [2].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.54 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 3.0176 mL | 15.0880 mL | 30.1759 mL | |
| 5 mM | 0.6035 mL | 3.0176 mL | 6.0352 mL | |
| 10 mM | 0.3018 mL | 1.5088 mL | 3.0176 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
