Rapamycin-D3 (Sirolimus-D3) is a tri-deuterated form of Rapamycin, which is an mTOR inhibitor with IC50 of 0.1 nM in HEK293 cells. Rapamycin acts as an autophagy activator, and an immunosuppressant.

Solubility Data
| Solubility (In Vitro) | DMSO : ~110 mg/mL (~119.93 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.75 mg/mL (3.00 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 27.5 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: ≥ 2.75 mg/mL (3.00 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 27.5 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.) |
