Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
1.4mg/ml Taking the 1 mL working solution as an example, add 50 μL of 28 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil
0.23mg/ml Taking the 1 mL working solution as an example, add 50 μL of 4.6 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Pralatrexate is an antifolate, and structurally a folate analog. Its IC50 is < 300 nM in some cell lines. Pralatrexate induces tumor cell apoptosis.
Targets
DHFR [1]
In vitro Pralatrexate and bortezomib exhibits concentration- and time-dependent cytotoxicity against a broad panel of T-lymphoma cell lines. Pralatrexate shows synergism when combined with bortezomib in all cell lines studied. Pralatrexate also induces potent apoptosis and caspase activation when combined with bortezomib across the panel. Pralatrexate significantly modulates the expression of p27, NOXA, HH3, and RFC-1 as assessed by Western blot assays. [1] Pralatrexate is rationally designed for improved cellular transport via RFC-1, and to have greater intracellular drug retention through the enhanced formation of polyglutamylated conjugates. Pralatrexate is thought to exert its pharmacological effect primarily through inhibition of DHFR, having an IC50 in the picomolar range. [2] Pralatrexate demonstrates superior intracellular transport via the reduced folate carrier, and increased accumulation within cells by enhanced polyglutamylation. Pralatrexate exhibits antitumor activity that is superior to the activity of other antifolates. [3] Pralatrexate's enhanced activity relative to methotrexate (MTX) is due to its much more rapid rate of transport and polyglutamation, the former less important when the carrier is saturated. [4]
In vivo Pralatrexate treatment results in treatment-related toxicity in MV522 mice models, as determined by significant weight loss in some animals prior to death; however, remaining mice regains all lost weight by Day 35. [2]
