Biological Activity

Description Lurbinectedin, a DNA minor groove covalent binder with potent in vitro and in vivo anti-tumour activity. Lurbinectedin inhibits RMG1 and RMG2 cell growth with IC50 of 1.25 nM and 1.16 nM, respectively.
Targets
DNA minor groove [1] RMG2 cell growth [1]
(Cell-based assay)		 RMG1 cell growth [1]
(Cell-based assay)
1.16 nM 1.25 nM
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]
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]

Protocol (from reference)

Cell Assay:

[1]
  • 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.
Animal Study:

[1]
  • Animal Models

    5- to 7-week-old nude mice

  • Dosages

    0.180 mg/kg

  • Administration

    IV
