Biological Activity

Description

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.

Targets

Thymidylate synthase ^[1] (Cell-free assay)	DHFR ^[1] (Cell-free assay)	GARFT ^[1] (Cell-free assay)
1.3 nM(Ki)	7.2 nM(Ki)	65 nM(Ki)

In vitro

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]

In vivo

The combination of omepetinib and pemetrexed enhances apoptosis via a PLK1 signaling pathway, and the anti-tumor effect against xenografts harboring the EGFR mutation in vivo.^[4]

Protocol (from reference)

Cell Assay:^{^[4]}	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.
