生物活性

製品説明 Agerafenib (CEP-32496) is a highly potent inhibitor of BRAF(V600E/WT) and c-Raf with Kd of 14 nM/36 nM and 39 nM, also potent to Abl-1, c-Kit, Ret (c-Ret), PDGFRβ and VEGFR2, respectively; insignificant affinity for MEK-1, MEK-2, ERK-1 and ERK-2. Phase 1/2.
in vitro CEP-32496 inhibits A375 cell (BRAFV600E) proliferation with EC50 of 78 nM. CEP-32496 exhibits more sensitive cytotoxicity for tumor cell lines (A375, SK-MEL-28, Colo-205, Colo-679, and HT-144) expressing mutant BRAF than those expressing wild-type BRAF (HCT116, Hs578T, LNCaP, DU145, and PC-3). [1] CEP-32496 inhibits mitogen-activated protein (MAP)/extracellular signal-regulated (ER) kinase (MEK) phosphorylation (pMEK) in human melanoma (A375) and colorectal cancer (Colo-205) cell lines with IC50 of 78 nM and 60 nM, respectively. [2]
in vivo CEP-32496 exhibits good stability in mouse, dog, monkey, and human liver microsomal preparations with measured intrinsic clearance values of <23 (μL/min)/mg and t1/2 > 60 min in all assays. CEP-32496 (30 mg/kg, orally, BID) exhibits tumor stasis and a 40% incidence of partial tumor regressions (PRs) in Colo-205 xenograft mouse model, whereas the 100 mg/kg dose group exhibits both tumor stasis and an 80% incidence of PRs. CEP-32496 (30 mg/kg, orally, BID) leads to a 50% and 75% inhibition of normalized pMEK in tumor lysates at the 2 hours and 6 hours postdose time point, respectively, while a 55 mg/kg dose results in a 75% to 57% inhibition of pMEK at 2 hours through 10 hours post administration in Colo-205 xenograft mouse model. [1] CEP-32496 is orally bioavailable in multiple preclinical species (>95% in rats, dogs, and monkeys). CEP-32496 (100 mg/kg) results in inhibition of pMEK and pERK and sustained tumor stasis and regressions in BRAF(V600E) colon carcinoma xenografts in nude mice. [2]
特徴 High binding affinity for both BRAF (V600E) mutation and related c-Raf, but no significant affinity for other kinases of MAPK pathway.

キナーゼアッセイ Binding assay
Kinases are produced displayed on T7 phage or by expression in HEK-293 cells and tagged with DNA. Binding reactions are performed at room temperature for 1 hour, and the fraction of kinase not bound to test compound is determined by capture with an immobilized affinity ligand and quantitation by quantitative PCR. Each kinase is tested individually against CEP-32496. Kd values are determined using eleven serial 3-fold dilutions and presented as mean values from experiments performed in duplicate. Variability between individual values is less than 2-fold.
細胞アッセイ 細胞株 A375 cell lines
濃度 78 nM
反応時間 72 hours
実験の流れ Cells are seeded at 104 cells per well in DMEM with 10% fetal calf serum and allowed to attach. The cells are washed with PBS and switched to DMEM with 0.5% of serum and incubated overnight. CEP-32496 is then added at various concentrations with a final DMSO concentration of 0.5% and incubated for 72 h. At the end of incubation, a Cell Titer Blue is added per instructions, and incubation is continued for 3 hours. Remaining viable cells are quantified by measuring the strength of the fluorescence signal using SoftMax Pro (excitation at 560 nm and emission at 590 nm). IC50 values are derived using a 9-point curve fitted with Igor Pro and are presented as mean values from experiments performed in duplicate. Variability between individual values is less than 2-fold.
