Pelitrexol
Based on 2 publication(s) in Google Scholar
Pelitrexol (AG 2037) is an inhibitor of glycinamide ribonucleotide formyltransferase (GARFT), a purine biosynthetic enzyme. Pelitrexol also inhibits mTORC1 by reducing GTP-bound Rheb level, a mTORC1 obligate activator. Pelitrexol shows robust tumor growth suppression in mice.

Biological Activity
GARFT[1]
Pelitrexo (150 nM; 24 h) profoundly inhibits mTORC1 activity by reducing intracellular guanine nucleotides level as well as GTP-bound Rheb protein level in A549 cells[1].
Pelitrexo (0-1000 mM; 16 h) strongly inhibits the phosphorylation level of ribosomal protein S6 (S6RP), S6K1, and Chk1 in a dose-dependent manner in NCI-H460 cells[1].
Pelitrexo (100 nM; 48 h) arrests cell cycle at G1 phase in NCI-H460 cells[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (4.49 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (4.49 mM); Clear solution
