Mechanism of Action

Targets

topoisomerase I ^[1]

In vitro
In vitro	Exatecan Mesylate shows both high potency against a series of 32 malignant cell lines and significant topoisomerase I inhibition in vitro. The anti‐proliferative activity of this compound is about 6 and 28 times greater than that of SN‐38 or SK&F 10486‐A, respectively.^[1]

In Vivo
In vivo	In mice, the antitumor activity of three doses of Exatecan Mesylate administered i.v. at 4‐day intervals against human gastric adenocarcinoma SC‐6 xenografts is greater than that of CPT‐11 or SK&F 10486‐A. Moreover, this compound overcame P‐glycoprotein‐mediated multi‐drug resistance. These data suggest that it has a high antitumor activity and is a potential therapeutic agent.^[1]

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.
