产品描述 V-9302 (V9302) is a competitive antagonist of transmembrane glutamine flux that selectively and potently targets the amino acid transporter ASCT2 (IC50: 9.6 uM).
靶点活性 ASCT2:9.6 μM (in HEK-293 cells)
体外活性 V-9302 inhibited ASCT2-mediated glutamine uptake in human cells in a concentration-dependent fashion and exhibited a 100-fold improvement in potency (IC50 V-9302 = 9.6 μM) over gamma-L-glutamyl-p-nitroanilide (GPNA; IC50 = 1000 μM). The EC50 concentrations for the four colorectal cancer (CRC) cell lines exposed to V-9302 ranged from approximately 9-15 μM.
体内活性 Following a single dose of V-9302 (75 mg/kg, 4 h), [18F]-4F-glutamine uptake in tumors was reduced by approximately 50% to levels below background uptake in healthy muscle. Over the treatment course, V-9302 (75 mg/kg/day, 21 days) prevented tumor growth compared to vehicle controls in both HCT-116 and HT29 xenograft models.
细胞实验 Live-cell amino acid uptake assays using HEK293 cells were carried out in 96-well plates. 96-well plates were coated with poly-D-lysine prior to the assay. Cells were plated at a density of 35,000 cells per well 24 h prior to carrying out the assay. Each set of conditions was replicated at least three times, technically and biologically. Cells were washed three times with 100 μL of assay buffer (containing 137 mM NaCl, 5.1 mM KCl, 0.77 mM KH2PO4, 0.71 mM MgSO4.7H2O, 1.1 mM CaCl2, 10 mM D-glucose, and 10 mM HEPES) to remove cell media. 3H-amino acid (500 nM) in the same buffer was added concomitantly with V-9302 and allowed to incubate for 15 min at 37 oC. For ASCT2-mediated 3H-glutamine uptake assays, 5 mM of the system-L inhibitor 2-amino-2-norbornanecarboxylic acid (BCH) was added and the assay buffer was adjusted to pH 6.0. For selectivity studies, no BCH was added and the assay was conducted at pH 7.4. Following the incubation period, the 3H-glutamine/inhibitor was removed and the cells were washed three times with assay buffer. The cells were then lysed by the addition of 50 μL of 1 M NaOH. For reading, 150 μL of scintillation fluid was added and the plates were counted on a scintillation counter. IC50 was calculated using GraphPad Prism.
动物实验 Animal handling methods for PET imaging studies were conducted as reported. Prior to imaging, animals were allowed to acclimate to facility environment for at least 1 h in a warmed chamber at 31.5 °C. Animals were administered 10.4–11.8 MBq 4-[18F]fluoroglutamine via intravenous injection and imaged using a scanner. During imaging, animals were maintained under 2% isoflurane anesthesia in oxygen at 2 L/min and kept warm for the duration of the PET scan. PET images in xenograft-bearing mice were acquired as 60-minute dynamic data sets. Imaging was initiated three hours post-treatment following vehicle or V-9302 (75 mg/kg) administration. PET data were reconstructed using a three-dimensional (3D) ordered subset expectation maximization/maximum a posteriori (OSEM3D/MAP) algorithm. The resulting three-dimensional reconstructions had an x-y voxel size of 0.474 mm and inter-slice distance of 0.796 mm. ASIPro software was used to manually draw 3D regions of interest (ROIs) surrounding the entire tumor volume. 4-[18F]fluoroglutamine uptake was quantified as the percentage of the injected dose per gram of tissue (%ID/g). Significance was calculated using a t-test in Graphpad Prism. Error is reported as standard deviation (SD).
