Uprosertib 是一种有效的,选择性的Akt广谱抑制剂,对 Akt1/Akt2/Akt3 的IC50值分别为 180/328/38 nM。
产品描述
Uprosertib (GSK2141795) is a selective, ATP-competitive, and orally bioavailable Akt inhibitor with IC50 of 180 nM, 328 nM, and 38 nM for Akt 1, 2 and 3, respectively. Phase 2.
体外活性
Uprosertib inhibits multiple AKT substrate phosphorylation levels, including GSK3β, PRAS40, FOXO and Caspase 9 in both BT474 and LNCaP cells. Uprosertib preferentially inhibits the proliferation of human cancer cells lines with AKT pathway activation. In LNCaP, BT474, A3 and I9.2 cells lines, Uprosertib also causes cell cycle arrest. [2] In both SKOV3 and PEO4 cells, Uprosertib causes growth-arrest as single agent, and enhances cisplatin-induced apoptosis. [3]
体内活性
In mice bearing BT474 breast tumor xenografts, Uprosertib (100 mg/kg, p.o.) results 61% tumor growth inhibition. In mice bearing SKOV3 ovarian tumor xenografts, Uprosertib (30 mg/kg, p.o.) results 61% tumor growth inhibition. [2]
激酶实验
Selectivity profiling experiments: The lysates (5 mg of total protein each) are preincubated with 0 (DMSO control), 2.5 nM, 25 nM, 250 nM, 2.5 μM or 25 μM free compound (GSK690693 or GSK2141795) on an end-over-end shaker for 45 min at 4 °C. Subsequently, lysates are incubated with beads (coupled Akt probe or kinobeads) for 1 h at 4 °C, for both qualitative and quantitative experiments. The beads are washed with 1× CP buffer and collected by centrifugation. Bound proteins are eluted with 2× NuPAGE LDS sample buffer, and eluates are reduced and alkylated by 50 mM dithiothreitol and 55 mM iodoacetamide.
细胞实验
Cell lines are typically grown in RPMI 160 medium containing 10% FBS. Some cell lines are grown in media specified by the vendor. A 3-day proliferation assay using CellTiter-Glo is performed to measure the growth inhibition by the compounds at 0–30 μM. Cell growth is determined relative to untreated (DMSO) controls. EC50's are calculated from inhibition curves using a 4- or 6-parameter fitting algorithm in the Assay Client application.(Only for Reference)
