名稱 | Encorafenib |
描述 | Encorafenib (LGX818) is an orally available mutated BRaf V600E inhibitor(IC50=0.3 nM) with potential antineoplastic activity. |
細(xì)胞實(shí)驗(yàn) | LGX818 is dissolved in DMSO. A375 is a melanoma cell line that harbors the B-Raf V600E mutation. A375-luc cells engineered to express luciferase is plated to 384-well white clear bottom plates as 1,500 cells/50 μL/well in DMEM containing 10% FBS. Test compounds, dissolved in 100% DMSO at appropriate concentrations, are transferred to the cells by a robotic Pin Tool (100 mL). The cells are incubated for 2 days at 25°C, then 25 μL of BrightGloTM is added to each well and the plates are read by luminescence. The concentration of each compound for 50% inhibition (IC50) is calculated by non-linear regression using XL Fit data analysis software. wild type and V600E B-Raf. |
激酶實(shí)驗(yàn) | The Raf kinase activity reaction is started by the addition of 10 μL per well of 2×ATP diluted in assay buffer. After 3 hours (bRaf(V600E)) or 1 hour (c-Raf), the reactions are stopped with the addition of 10 μL of stop reagent (60 mM EDTA). Phosphorylated product is measured using a rabbit anti-p-MEK antibody and the Alpha Screen IgG (ProteinA) detection Kit, by the addition of 30 μL to the well of a mixture of the antibody (1:2000 dilution) and detection beads (1:2000 dilution of both beads) in bead buffer (50 mM Tris, pH 7.5, 0.01% Tween20). The additions are carried out under dark conditions to protect the detection beads from light. A lid is placed on top of the plate and incubated for 1 hour at room temperature, then the luminescence is read on a PerkinElmer Envision instrument. The concentration of each compound for 50% inhibition (IC50) is calculated by non-linear regression using XL Fit data analysis software |
體外活性 | 在A375(BRAFV600E)人類黑色素瘤細(xì)胞系中,Encorafenib抑制磷酸化ERK(EC50 = 3 nM),從而強(qiáng)效抑制增殖(EC50 = 4 nM)。在針對(duì)100種激酶的檢測(cè)中未觀察到顯著活性(IC50 > 900 nM),且Encorafenib不抑制表達(dá)野生型BRAF的400多種細(xì)胞系的增殖。Encorafenib的高效力部分歸因于其從BRAFV600E解離的極其緩慢速率,這一點(diǎn)在其他RAF抑制劑中未見。生化實(shí)驗(yàn)中,解離半衰期超過(guò)24小時(shí),這意味著在化合物清洗后,細(xì)胞中的靶點(diǎn)抑制作用能持續(xù)。[1] |
體內(nèi)活性 | Encorafenib通過(guò)口服,在低至6 mg/kg劑量下便可強(qiáng)效(75%)并持續(xù)(>24小時(shí))降低磷酸化MEK水平,即便是在化合物從血液循環(huán)清除后的單劑量PK/PD研究中,對(duì)人源黑色素瘤異種移植模型(BRAFV600E)仍然有效。在免疫缺陷的小鼠和大鼠體內(nèi),Encorafenib在低至1 mg/kg的劑量下引起多種BRAF突變型人腫瘤異種移植模型的腫瘤退縮。與體外數(shù)據(jù)一致,Encorafenib對(duì)BRAF野生型腫瘤在高達(dá)300 mg/kg bid的劑量下無(wú)活性,但具有良好的耐受性和曝光量的線性增加。在更具疾病相關(guān)性的自發(fā)性轉(zhuǎn)移性黑色素瘤和黑色素瘤腦轉(zhuǎn)移模型中也實(shí)現(xiàn)了療效。Encorafenib是一種強(qiáng)效且選擇性的RAF激酶抑制劑,具有獨(dú)特的生化特性,有助于其出色的藥理學(xué)特性。[1] |
