| Product Description |
Vevorisertib (ARQ 751) trihydrochloride is a selective, allosteric, pan- AKT and AKT1-E17K mutant inhibitors. Vevorisertib trihydrochloride potently inhibit phosphorylation of AKT . Vevorisertib trihydrochloride has Kd values of 1.2 nM and 8.6 nM for AKT1 and AKT1-E17K, respectively. Vevorisertib trihydrochloride has IC 50 values of 0.55, 0.81, and 1.3 nM for AKT1 , AKT2 , and AKT3 , respectively. Vevorisertib trihydrochloride can be used for the research of cancer In Vitro Vevorisertib trihydrochloride (0, 12, 33, 111, 333, 1000 nM, 2 hours) inhibits phosphorylation of AKT1-E17K. Vevorisertib trihydrochloride (1 μM for 2 hours; NIH 3T3 cells are transfected with either pcDNAAKT-WT-GFP or pcDNA-E17K-GFP) inhibits plasma membrane translocation of AKT-WT and AKT1-E17K irrespective of the presence of growth factors. Vevorisertib trihydrochloride (5 μM) exhibites 57% inhibition of full-length AKT1. Vevorisertib trihydrochloride (0, 0.012, 0.037, 0.11, 0.33, 1 μM; 2 hours) shows a dose-dependent effect on mTORC1 and AKT direct substrates including PRAS40, GSK3β, FOXO, BAD, and AS160 in cancer cell lines. Vevorisertib trihydrochloride has anti-proliferative effect on esophageal, breast, and head and neck cancer cells (GI 50 < 1 μM). Vevorisertib trihydrochloride exhibits strong anti-proliferative activity in PIK3CA mutant cell lines. Vevorisertib trihydrochloride (MK-4440)/imatinib mesylate (IM) combination shows cell cycle arrest, and increases cell death of gastrointestinal stromal tumor (GIST) cells. Vevorisertib trihydrochloride exhibits strong anti-proliferative activity in PIK3CA mutant cell lines: Breast Cancer Cell Lines GI 50 (nM) PIK3CA ER PR HER2 T47D 1.05 H1047R + + - EFM-19 1.54 H1047R + + - MCF-7 2.20 E545K + + - BT474 3.25 K111N + + + MDA-MB-453 6.05 H1047R - - + MCE has not independently confirmed the accuracy of these methods.

Western Blot AnalysisCell Line: 293T cells (transiently transfected with pcDNA-E17K-GFP) Concentration: 0, 12, 33, 111, 333, 1000 nM Incubation Time: 2 hours Result: Inhibited phosphorylation of AKT1-E17K. Western Blot AnalysisCell Line: Cancer cell lines: MDA-MB 453 (PIK3CAH1047R; Her2 amp), NCI-H1650 (PTEN ), KU-19-19 (AKT1-E17K&E49K; NRas Q61R) Concentration: 0, 0.012, 0.037, 0.11, 0.33, 1 μM Incubation Time: 2 hours Result: Showed a dose-dependent effect on mTORC1 and AKT direct substrates including PRAS40, GSK3β, FOXO, BAD, and AS160. In Vivo Vevorisertib trihydrochloride (25, 50 and 75 mg/kg; p.o.; 5 days dosing followed by a 4 day dosing holiday for 20 days) shows potent tumor growth inhibition of 68, 78 and 98%, respectively . Vevorisertib trihydrochloride (5, 10, 20, 40, 80, and 120 mg/kg; p.o. daily for ten days) shows tumor growth inhibition of 29, 33, 50, 73, 83, and 92%, respectively . Vevorisertib trihydrochloride reachs C max plasma concentrations of ≥2 μM . Vevorisertib trihydrochloride is generally well-tolerated at dose levels up to 120 mg/kg . Vevorisertib trihydrochloride (MK-4440)/IM combination shows superior efficacy in an IM-sensitive preclinical model of GIST compared with either single agent. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
