BTK
PCI-33380 targets Bruton's tyrosine kinase (BTK) with high selectivity and irreversible binding. The compound covalently binds to BTK, forming a stable inhibitor-enzyme complex. Its fluorescent properties, with excitation/emission wavelengths of 532/555 nm, allow for visualization and tracking of BTK in cells and tissues. |
|---|---|
| ln Vitro |
PCI-33380 bound to Btk could be found using fluorescent gel scanning and denaturing gel electrophoresis[2].
In vitro, PCI-33380 specifically binds to BTK protein in B-cell lysates. The fluorescent probe allows for detection of BTK in cellular assays without the need for antibodies or other detection reagents. The compound's activity-based probe design enables the study of BTK occupancy, localization, and dynamics in living cells. |
| ln Vivo |
In vivo, PCI-33380 has been used to study BTK engagement in animal models. The fluorescent probe allows for tracking of BTK inhibition and binding in tissues, providing a direct link between inhibitor binding and biological responses. This makes PCI-33380 a valuable tool for pharmacodynamic studies of BTK inhibitors.
|
| Enzyme Assay |
In vitro binding assays for PCI-33380 involve incubating the fluorescent probe with B-cell lysates or purified BTK protein. The binding of PCI-33380 to BTK is detected by fluorescence polarization or by measuring fluorescence intensity after gel electrophoresis. Competition assays with unlabeled BTK inhibitors are used to confirm specificity.

| Cell Assay |
Cell Line: Human B cells.
Concentration: 2 μM. Incubation Time: 1 h. Result: Found that 10 nM of PCI-32765 was sufficient to fully occupy the active site of Btk in primary B cells in culture by using the fluorescently tagged derivative PCI-33380. Cellular assays are performed using B-cell lymphoma cell lines such as Ramos or other BTK-expressing cells. Cells are treated with PCI-33380 at various concentrations, and BTK binding is visualized by fluorescence microscopy or flow cytometry. The compound's ability to label BTK in living cells allows for real-time monitoring of BTK localization and dynamics. |
| Animal Protocol |
In vivo studies are conducted in mouse models of B-cell malignancies. PCI-33380 is administered intravenously or intraperitoneally, and tissues are collected for fluorescence imaging. BTK engagement and inhibition are assessed by measuring fluorescence intensity in tissues, and the correlation between inhibitor binding and biological responses is evaluated.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (2.92 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (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 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (2.92 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (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 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.  (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
