Biological Activity
| ln Vitro | FT-1518 is a new family of selective, powerful, orally accessible mTORC1 and mTORC2 inhibitors with anti-tumor efficacy. FT-1518 demonstrates substantial growth inhibitory action against a broad range of blood and solid tumor cell lines, with most activities in the low nanomolar range. FT-1518 potently inhibits mTOR pathway biomarkers (mTORC 1 and 2 biomarkers [pAkt(S473) and pS6(S240/244) or p70 S6K), but not PI3K biomarkers, in cells [pAkt(T308)][1]. |
| ln Vivo | In several solid tumor xenografts, FT-1518 showed dose-dependent and improved tumor growth inhibition (TGI) [1]. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~5 mg/mL (~12.68 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 0.5 mg/mL (1.27 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 5.0 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: ≥ 0.5 mg/mL (1.27 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 5.0 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. Solubility in Formulation 3: ≥ 0.5 mg/mL (1.27 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 5.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
