Trabectedin (Ecteinascidin 743, ET-743) is a marine alkaloid isolated from the Caribbean tunicate Ecteinascidia turbinata with antitumour activity. Trabectedin binds to the N2 of guanine in the minor groove, causing DNA damage and affecting transcription regulation in a promoter- and gene-specific manner.

Biological Activity

Description	Trabectedin (Ecteinascidin 743, ET-743) is a marine alkaloid isolated from the Caribbean tunicate Ecteinascidia turbinata with antitumour activity. Trabectedin binds to the N2 of guanine in the minor groove, causing DNA damage and affecting transcription regulation in a promoter- and gene-specific manner.

In vitro
In vitro	Trabectedin can block EWS-FLI1 transcription factor activity, suppress Werner syndrome protein (WRN) expression and selectively sensitize Ewing sarcoma cells to the DNA-damaging effects of SN38. <sup><a class="sref" href="#s_ref">[1]</a></sup><sup><a class="sref" href="#s_ref">[3]</a></sup>
Cell Research	Cell lines	Ewing sarcoma cells
	Concentrations	10 nM
	Incubation Time	18 h
	Method	RNAiMax Lipofectamine (4.5 mL per well in a 6-well dish) was added to siRNA targeting the EWS-FLI1 breakpoint site II, complexed, combined with cells, and incubated for 36 to 48 hours before collection for Western blot analysis.

In Vivo
In vivo	In Tumor-Bearing Mice, trabectedin does not have an impact on the functional activity of MDSC but does significantly reduce the number of Ly6C<sup>high</sup> cells, the most suppressive subset. <sup><a class="sref" href="#s_ref">[4]</a></sup>

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.
