In vitro
In vitro

Lurbinectedin exhibits significant antitumor activity toward chemosensitive and chemoresistant CCC cells in vitro. Lurbinectedin plus SN-38 combination has strong synergistic effects on both the cisplatin-resistant and paclitaxel-resistant CCC cell lines.[1]

Cell Research Cell lines The human ovarian CCC cell lines (RMG1, RMG2, KOC7C, HAC2)
Concentrations 0.1 nM, 0.3 nM, 1 nM, 3 nM
Incubation Time 48 h
Method

CCC cells (2~5×105) are treated with lurbinectedin, SN38 or in combination of the two drugs at the indicated concentrations for 48 hours. Then, the cells are harvested and stained with PI and annexin V using the annexin V-fluorescein isothiocyanate (FITC) apoptosis detection kit, according to the manufacturer's instructions. Fluorescence data are collected using flow cytometry. The sum total of early apoptotic cells (annexin V(+), PI(−) cells) and late apoptotic cells (annexin V(+), PI(+) cells) is defined as the total number of apoptotic cells. The experiments are repeated at least three times.

In Vivo
In vivo

An examination of mouse CCC cell xenografts reveals that lurbinectedin significantly inhibits tumor growth. Lurbinectedin plus SN-38 combination results in a significant synergistic effect. Everolimus significantly enhances the antitumor activity of lurbinectedin-based chemotherapies.[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.
