生物活性

製品説明 SGX-523は、4 nMのIC50を持つ選択的なMet (c-Met)阻害剤であり、BRAFV599E、c-Raf、Abl、およびp38αには活性がありません。第1相。
in vitro SGX-523 belongs to the class of c-Met/hepatocyte growth factor receptor (HGFR) tyrosine kinase inhibitors. This compound stabilizes MET in a unique inactive conformation that is inaccessible to other protein kinases, suggesting an explanation for its selectivity. It potently inhibits the purified MET catalytic domain but not the closely related receptor tyrosine kinase RON. This chemical indicates ATP-competitive inhibition with higher apparent affinity for the less active, unphosphorylated form of MET [MET-KD(0P), with a Ki of 2.7 nM] versus the more active phospho-enzyme [MET-KD(3P), with a Ki of 23 nM], a phenomenon consistent with preferential binding to an inactive enzyme conformation. It inhibits MET-mediated signaling, cell proliferation and cell migration at nanomolar concentrations but had no effect on signaling dependent on other protein kinases, including the closely related RON, even at micromolar concentrations.
in vivo SGX523 significantly retards the growth of preestablished GTL16 tumors when administered orally at doses of ≥10 mg/kg twice daily. This compound potently inhibits U87MG tumor growth; at 30 mg/kg dosed twice daily, it leads to clear regression of U87MG tumors. This chemical, dosed twice daily at 30 mg/kg, also retards the growth of H441 tumors with concomitant reduction in tumor MET autophosphorylation levels. Its inhibition of MET in vivo is associated with the dose-dependent inhibition of growth of tumor xenografts derived from human glioblastoma, lung and gastric cancers, confirming the dependence of these tumors on MET catalytic activity.

キナーゼアッセイ Kinase assays
Initial rate constants are measured at 21 °C in the presence of 100 mM HEPES (pH 7.5), 0.3 mg/mL poly(Glu-Tyr) peptide substrate, 10 mM MgCl2, 1 mg/mL bovine serum albumin, 5% DMSO, 20 nM MET-KD and various concentrations of ATP and SGX523. Total reaction volumes (20 μL) are quenched with 20 μL Kinase-Glo detection buffer. Luminescence is detected in a plate-reading luminometer and the results are analyzed by nonlinear regression.
細胞アッセイ 細胞株 MDCK cells
濃度 200 nM
反応時間 18 hours
実験の流れ MDCK cells are seeded at 1 × 103 per well in a 24-well plate and incubated at 37 °C in 5% CO2 for 1 week in MEM and 10% fetal bovine serum. HGF (90 ng/mL) and various concentrations of SGX-523 are added and the cells are incubated for another 18 hours (37 °C, 5% CO2 humidified incubator) and visualized. A549 cells are plated in 12-well plates (6 × 104 per well) and incubated to confluence to investigate cell migration. A channel is introduced into the monolayers by scratching with a pipette tip. Various dilutions of this compound are added in starve medium in the presence and absence of HGF (90 ng/mL).The wells are checked for cell migration after twenty-fou
