GNE-477 is a novel, potent and efficacious dual inhibitor of PI3K (IC50=4 nM)/mTOR(Ki=21 nM). The PI3K/AKT/mTOR signaling pathway is regarded as an attractive area of research for the identification of oral small molecule inhibitors. PI3K-α, β, δ, and were all found to be inhibited in vitro by GNE-477, with IC50 values of 4, 86, 6, and 15 nM, respectively. A direct comparison of GNE-477 with its des-methyl analog in vivo showed that mice and dogs also exhibit the trend of decreased in vivo clearance that is seen in rats. In contrast to GNE-477, which had a low clearance in dogs, the des-methyl analog was cleared at a rate that was two-thirds that of hepatic blood flow. In a study evaluating the tumor growth inhibition of a PC3 tumor xenograft10 over a period of 14 days, stasis was reached at a dose of GNE-477 of 20 mg/kg QD, and significant inhibition was discovered with doses as low as 1 mg/kg QD. GNE-477 was generally well tolerated throughout this study, as evidenced by acceptable weight loss levels comparable to those in the vehicle cohort.
| Targets |
PI3Kα (IC50 = 4 nM); mTOR (IC50 = 21 nM)
|
|---|---|
| ln Vitro |
GNE-477 (Compound 8) has improved potency in the MCF7.1 cell proliferation assay with an EC50 of 143 nM[1].
|
| ln Vivo |
GNE-477 also exhibits stasis in a PC3 tumor growth inhibition study. In a 14-day experiment examining the tumor growth inhibition of a PC3 tumor xenograft, stasis is reached at a dose of 20 mg/kg QD, and significant inhibition is seen at doses as low as 1 mg/kg QD. The acceptable levels of weight loss comparable to those seen with the animals in the vehicle cohort during this study show that GNE-477 is generally well tolerated.[1]
|
| Animal Protocol |
Mice, Rats and Dogs[1]. The GNE-477 HCl salt is administered intravenously to female nu/nu mice (1 mg/kg) and orally to female nu/nu mice (5 mg/kg) as a solution in 80% PEG. The GNE-477 TFA salt is administered intravenously to male rats (1 mg/kg) and orally to male rats (5 mg/kg) as a solution in 80% PEG. The GNE-477 HCl salt is administered to male beagle dogs as an intravenous solution (1 mg/kg) in 10% HP-CD and as an oral suspension (2 mg/kg) in MCT. GNE-477's effectiveness in the PC3-NCI tumor xenograft model is studied. At the conclusion of the study (day 14), the percentage of tumor growth inhibition (TGI) is assessed and contrasted with the vehicle control group.

| Solubility (In Vitro) |
DMSO: 25 ~16.7 mg/mL (33~49.5 mM)

|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 1.67 mg/mL (3.31 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 16.7 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 1.67 mg/mL (3.31 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 16.7 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
