Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 60 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO Corn oil
3.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 60 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 CL-387785 (EKI-785, WAY-EKI 785) is an irreversible, and selective EGFR inhibitor with IC50 of 370 pM.
in vitro CL-387785 blocks EGF-stimulated autoposphorylation of the receptor in cells (IC50, 5 nM), In cell lines that overexpress EGF-R or c-erbB-2, CL-387785 inhibits cell proliferation (IC50, 31 nM) primarily in a cytostatic manner. [1]
in vivo In nude mice overexpressed EGF-R, CL-387785 (80 mg/kg/day, p.o.) profoundly blocks the growth of tumor. [1] In murine models of autosomal recessive polycystic kidney disease (ARPKD), treatment of Balb/c-bpk/bpk (BPK) mice with CL-387785 (90 mg/kg, i.p.) results in a marked reduction of collecting tubule cystic lesions, improved renal function, decreased biliary epithelial abnormalities, and prolonged life span. [2] Doses of CL-387785 as low as 25 mg/kg reduces the growth of HCA-7-induced xenograft tumor, and a dose of 100 mg/kg prevents tumor growth entirely. Dose of 50 mg/kg CL-387785 is effective at reducing the growth of HCT-116-induced xenograft tumor. [5]

キナーゼアッセイ Liquid scintillation
Stock solutions of 500 μM CL-387785 (prepared in 100% DMSO) are diluted to the desired concentration with 30 mM HEPES, pH 7.4. Ten microliters of CL-387785 at various concentrations are incubated with 3 μL of recombinant enzyme (1:120 dilution in 100 mM HEPES, pH 7.4) on ice for 10 min. Then, 5 μL peptide (400 μM final concentration of RR-SRC composed of Arg-Arg-Leu-Ile-Glu-Asp-Ala-Glu-Tyr-Ala-Ala-Arg-Gly), 10 μL of 4× reaction buffer containing 50 mM HEPES, pH 7.4, 80 μM ATP, 40 mM MnCl2, and 200 μM sodium orthovanadate. 0.30 μL [33P]ATP ( >2500 Ci/mmol), and 12 μL H2O are added. After incubation for 90 min at room temperature, the entire volume is spotted onto precut P81 filter papers. The filter discs are washed two times with 0.5% phosphoric acid, and radioactivity is measured using a liquid scintillation counter. Under these conditions, the specific activity of EGF-R kinase is approximately 0.50 pmol/mg/min.
細胞アッセイ 細胞株 Ba/F3-E709K, Ba/F3-l858r or Ba/F3-ERBB2 cells
濃度 ~2000 nM
反応時間 2 days
実験の流れ MTS assays are performed with the CellTiter 96@ AQueous One solution proliferation kit. A total of 10,000 cells per well in 96-well flat-bottomed plates are incubated with various concentrations of inhibitors for 48 h. The IC50 is determined from dose–response curves using XLfit4.
