| Name | CL-387785 |
| Description | CL-387785 (WAY-EKI 785)(EKI785; WAY-EKI 785) is an irreversible inhibitor of EGFR(IC50: 370+/-120 pM); is able to overcome resistance caused by the T790M mutation on a functional level. |
| Cell Research | MTS assays are performed with the CellTiter 96@ AQueous One solution proliferation kit. A total of 10,000 cells per well in 96-well ?at-bottomed plates are incubated with various concentrations of inhibitors for 48 h. The IC50 is determined from dose–response curves using XL?t4.(Only for Reference) |
| Kinase Assay | 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 Water 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. |
| In vitro | CL-387785 demonstrates significant inhibitory effects on the growth of HCT-116-induced xenograft tumors at a dose of 50 mg/kg. In nude mice expressing EGF-R, CL-387785 administered orally at 80 mg/kg/day effectively suppresses tumor growth. In a mouse model of autosomal recessive polycystic kidney disease, treatment with CL-387785 at 90 mg/kg intraperitoneally in Balb/c-bpk/bpk (BPK) mice significantly reduces cystic lesions in collecting ducts, improves kidney function, decreases abnormalities in bile duct epithelial cells, and extends lifespan. At 25 mg/kg, CL-387785 can reduce the growth of HCA-7-induced xenograft tumors, and a dose of 100 mg/kg completely inhibits tumor growth. |
| In vivo | CL-387785 effectively blocks EGF-mediated receptor autophosphorylation in cells (IC50: 5 nM). It principally acts as a cellular inhibitor, suppressing cell proliferation in cell lines overexpressing EGF-R or c-erbB-2 (IC50: 31 nM). |
| Storage | Shipping with blue ice/Shipping at ambient temperature. |
| Solubility Information | DMSO : 60 mg/mL (157.39 mM), Sonication is recommended.
Ethanol : < 1 mg/mL (insoluble or slightly soluble)
H2O : < 1 mg/mL (insoluble or slightly soluble)
