Biological Activity of GNE-317

DescriptionGNE-317 is a PI3K/mTOR inhibitor, is able to cross the blood-brain barrier (BBB).In Vitro:GNE-317 is an oxetane derivative of GDC-0980 synthesized with the goal of reducing substrate affinity for efflux transporters. In vitro, GDC-0980 and GNE-317 demonstrate similar profiles in MTS cytotoxicity experiments using the GL261 cell line[1].In Vivo:Seven days after i.c. inoculation with GL261-GFP-Luc cells, mice are treated once daily with the maximum tolerated dose of GDC-0980 (7.5 mg/kg), GNE-317 (30 mg/kg), or vehicle. For GL261, tumor growth is tracked through bioluminescence imaging on a weekly basis. There are no significant changes in GL261 tumor growth among the 3 groups. In assessing survival benefits in GL261, neither GDC-0980 nor GNE-317 provides survival benefit over the vehicle-treated animals. The fact that these drugs are not effective in vivo is suggested by the in vitro cytotoxicity data showing that the drugs have limited efficacy in inducing cell death in the GL261 cell line. Neither drug is effective in the GL261 tumor in spite of greater delivery and enhanced therapeutic targeting efficacy of GNE-317[1].

Protocol

Cell Assay [1]
GL261 is an aggressive C57BL/6J-derived glioma line. This cell line is transfected with both green fluorescent protein (GFP) and luciferase (Luc) from separate plasmids. The resultant monoclonal GL261-GFP-Luc cells are maintained in Dulbecco's modified Eagle's medium supplemented with 10% FBS and Penicillin/Streptomycin (100 U/mL) and cultured at 5% oxygen. Cell selection used 4 mg/mL Puromycin and 4 mg/mL G418. Cellular viability assays are set up in a 96-well format with 2000 cells plated per well in the culture conditions. Cells are incubated in the presence of drug or vehicle for 48 hours, and viability was assessed by MTS assay. Absorbance at 490 nm is used to determine viability and at 650 nm to account for background using a Synergy Mx automated plate reader. Numerical values from drug-treated wells are normalized to the values of vehicle-treated wells to yield percent survival[1].

Animal Administration [1]
Mice[1] GL261-GFP-Luc cells are implanted into 7-week-old C57BL/6J mice. When tumors reach 5e7 photons/s/cm2/sr (radiance), animals are orally administered the maximum tolerated dose of GDC-0980 (7.5 mg/kg), GNE-317 (30 mg/kg) or vehicle once a day for 3 days. The maximum tolerated doses are defined as the greatest dose that could be administered to mice with <10% drop in bodyweight. Even at these different doses, both doses provide similar plasma concentrations and thus the same overall systemic exposure. At 1 or 6 hours after the third dose, mice are euthanized with carbon dioxide and perfused with 30 mL PBS. With the aid of GFP goggles, brains are dissected into tumor core, tumor rim, and normal brain tissue. Tissue samples and blood are processed, and tissue specimens from each group are analyzed for drug concentrations using LC-MS/MS.

Distribution of the phosphatidylinositol 3-kinase inhibitors Pictilisib (GDC-0941) and GNE-317 in U87 and GS2 intracranial glioblastoma models-assessment by matrix-assisted laser desorption ionization imaging.[Pubmed:24754926]

Drug Metab Dispos. 2014 Jul;42(7):1110-6.

Glioblastoma multiforme (GBM) is the most common primary brain tumor in adults, and the limited available treatment options have not meaningfully impacted patient survival in the past decades. Such poor outcomes can be at least partly attributed to the inability of most drugs tested to cross the blood-brain barrier and reach all areas of the glioma. The objectives of these studies were to visualize and compare by matrix-assisted laser desorption ionization (MALDI) imaging mass spectrometry the brain and tumor distribution of the phosphatidylinositol 3-kinase (PI3K) inhibitors pictilisib (GDC-0941, 2-(1H-indazol-4-yl)-6-(4-methanesulfonyl-piperazin-1-ylmethyl)-4-morpholin-4-yl-t hieno[3,2-d]pyrimidine) and GNE-317 [5-(6-(3-methoxyoxetan-3-yl)-7-methyl-4-morpholinothieno[3,2-d]pyrimidin-2-yl)pyr imidin-2-amine] in U87 and GS2 orthotopic models of GBM, models that exhibit differing blood-brain barrier characteristics. Following administration to tumor-bearing mice, pictilisib was readily detected within tumors of the contrast-enhancing U87 model whereas it was not located in tumors of the nonenhancing GS2 model. In both GBM models, pictilisib was not detected in the healthy brain. In contrast, GNE-317 was uniformly distributed throughout the brain in the U87 and GS2 models. MALDI imaging revealed also that the pictilisib signal varied regionally by up to 6-fold within the U87 tumors whereas GNE-317 intratumor levels were more homogeneous. Liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) analyses of the nontumored half of the brain showed pictilisib had brain-to-plasma ratios lower than 0.03 whereas they were greater than 1 for GNE-317, in agreement with their brain penetration properties. These results in orthotopic models representing either the contrast-enhancing or invasive areas of GBM clearly demonstrate the need for whole-brain distribution to potentially achieve long-term efficacy in GBM.
