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

In vitro
Doxifluridine suppresses tube formation of HUVEC and vascular endothelial growth factor production by FU-MMT-1 cells. [1] This compound is converted to 5-FU and subsequently to FdUMP, and the results suggest that it exerts its cytotoxic effects through inhibition of TS and incorporation into RNA. [2] It is a fluoropyrimidine derivative that is activated preferentially in malignant cells by thymidine phosphorylase to form 5-fluorouracil (5-FU). This chemical is developed to improve the therapeutic index of 5-FU and to reduce toxicity, including the immunosuppressive, myelosuppressive, and cardiotoxic effects of 5-FU and other fluorinated pyrimidines. [3]
In vivo
Metronomic Doxifluridine alone significantly suppresses tumor growth compared with the untreated (control) group, while metronomic this compound in combination with TNP-470 significantly inhibits tumor growth compared with each treatment alone in in FU-MMT-1 xenografts. This compound in combination with TNP-470 also leads to a significant reduction of intratumoral vascularity. [1] It significantly inhibits the growth of KPL-4 tumors, reduces the tissue levels of IL-6, and alleviates body weight loss in nude mice bearing KPL-4 tumors. [4] This chemical results in a significant reduction in the activity of phenytoin p-hydroxylation in rats. It decreases the elimination rate constant and the total clearance in rats. [5]
