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.

Mechanism of Action

Targets/IC₅₀/Ki	Thymidylate synthase ^[1] (Cell-free assay) 1.3 nM(Ki) DHFR ^[1] (Cell-free assay) 7.2 nM(Ki) GARFT ^[1] (Cell-free assay) 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]
