体外研究
(In Vitro)

GNE-493 is a low molecular weight, potent dual inhibitor of pan-PI3 kinases and mTOR. GNE-493 displays approximately equipotent inhibition of Class I PI3K isoforms, is submitted for screening in a 142 kinase panel provided by Invitrogen’s SelectScreen service. Of these kinases, only three are subject to greater than 50% inhibition by GNE-493, and none are inhibited greater than 80% when tested at 1 μM. Subsequently measured IC50s demonstrated that GNE-493 is more than 100-fold selective for PI3Kα over these three unrelated kinases (Aurora A IC50>10 μM, MLK1 IC50=591 nM and SYK IC50=371 nM)[1].

体内研究
(In Vivo)

To confirm and compare in vivo efficacy, GNE-493 is examined in the human MCF7.1 breast cancer xenograft model that harbors a PI3Kα activating mutation. Mice bearing xenografts are dosed orally once daily with 10 mg/kg of GNE-493 for 21 continuous days. Similar to observations made in the PC3 prostate cancer xenograft model, 10 mg/kg of GNE-493 results in 73% tumor growth inhibition at day 21 when compared to vehicle control animals. When achieving comparable levels of drug exposure, GNE-493 shows a similar suppression of the PI3K pathway and consequently, a similar efficacy profile against MCF7.1 breast tumors[1].

Kinase Assay
[1]

Enzymatic activity of the Class I PI3K isoforms is measured using a fluorescence polarization assay that monitors formation of the product 3,4,5-inositoltriphosphate molecule as it competes with fluorescently labeled PIP3 for binding to the GRP-1 pleckstrin homology domain protein. An increase in phosphatidyl inositide-3-phosphate product results in a decrease in fluorescence polarization signal as the labeled fluorophore is displaced from the GRP-1 protein binding site. Class I PI3K isoforms are expressed and purified as heterodimeric recombinant proteins. Tetramethylrhodamine-labeled PIP3 (TAMRA-PIP3), di-C8-PIP2, and PIP3 detection reagents are used. PI3K isoforms are assayed under initial rate conditions in the presence of 10 mM Tris (pH 7.5), 25 μM ATP, 9.75 μM PIP2, 5% glycerol, 4 mM MgCl2, 50 mM NaCl, 0.05% (v/v) Chaps, 1 mM dithiothreitol, 2% (v/v) DMSO at the following concentrations for each isoform: PI3Kα, PI3β at 60 ng/mL; PI3Kγ at 8 ng/mL; PI3Kδ at 45 ng/mL. After assay for 30 min at 25°C, reactions are terminated with a final concentration of 9 mM EDTA, 4.5 nM TAMRA-PIP3, and 4.2 μg/mL GRP-1 detector protein before reading fluorescence polarization on an Envision plate reader. IC50s are calculated from the fit of the dose−response curves to a 4-parameter equation[1].

Animal Administration
[1]

Mice[1]
Human prostate cancer PC3 cells are resuspended in Hank’s Balanced Salt Solution and 3×106 cells implanted subcutaneously into the right hind flank of athymic nu/nu (nude) mice. Tumors are monitored until they reached a mean tumor volume of 150-200 mm3 prior to the initiation of dosing. MCF7.1 cells resuspended in a 1:1 mixture of Hank’s Buffered Salt Solution and Matrigel Basement Membrane Matrix, were 5×106 subcutaneously implanted into the right hind flank of athymic nu/nu (nude) mice. Prior to cell inoculation, 17 β-estradiol (0.36 mg/pellet, 60-day release) are implanted into the dorsal shoulder blade area of each nude mouse. After implantation of cells, tumors are monitored until they reached a mean tumor volume of 250-350 mm3 prior to initiating dosing. Female nude (nu/nu) mice that are 6-8 weeks old and weighed 20-30 g are used. Tumor bearing mice are dosed orally daily with 10 mg/kg of GNE-493 for 14 continuous days. Tumor volume is measured in two dimensions (length and width) and is analyzed using Excel version 11.2. Animal body weights are measured. Tumor sizes are recorded twice weekly over the course of the study (14-21 days)
