Pemetrexed

Synonyms: LY231514

Pemetrexed (LY231514) is a novel antifolate and antimetabolite for thymidylate synthase (TS), dihydrofolate reductase (DHFR) and glycinamide ribonucleotide formyltransferase (GARFT) with Ki of 1.3 nM, 7.2 nM and 65 nM in cell-free assays, respectively. Pemetrexed induces autophagy and apoptosis.

Osimertinib+pemetrexed treatment delays the emergence of resistance relative to monotherapy in vitro, also down-regulates the expression of the anti-apoptotic gene PLK1 in PC-9 and H1975.[4]
Cell Research Cell lines PC-9 and NCI-H1975 (H1975) cells
Concentrations 0.001, 0.01, 0.1, 1, 10 μM
Incubation Time 72 h
Method

Cells are plated in 96-well tissue culture plates at 5,000 cells/well and incubated at 37 ℃ for 24 h. Cells are then incubated with titrated concentrations of the drugs (0.001, 0.01, 0.1, 1, 10 μM) or vehicle (DMSO) at 37 ℃ for 72 h. Cell numbers are estimated using the Counting Kit-8. Protein extraction and western blotting are performed. Apoptosis assays are performed using the Annexin V-FITC Apoptosis Detection Kit.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
