Biological Activity

Description SCR7 is a specific DNA Ligase IV inhibitor, which blocks nonhomologous end-joining (NHEJ). It increases the efficiency of HDR-mediated genome editing up to 19-fold using CRISPR/Cas9 in mammalian cells and mouse embryos.
Targets
DNA Ligase IV [1]
In vitro

SCR7 effectively inhibits the formation of multimers at 200 μM and above. SCR7 successfully inhibits cell proliferation of MCF7, A549, HeLa, T47D, A2780, HT1080, and Nalm6 with IC50 of 40, 34, 44, 8.5, 120, 10, and 50 μM, respectively.[1] SCR7 suppresses the NHEJ repair of CRISPR-Cas9-induced DSBs.[2]SCR7 increases the efficiency of HDR-mediated genome editing up to 19-fold using CRISPR/Cas9 in mammalian cells and mouse embryos[3].
In vivo

SCR7 treatment (10 mg/kg, i.m.) significantly reduces breast adenocarcinoma-induced tumor, and exhibits 4-fold increase in lifespan compared with control group. However, in Swiss albino mice with Dalton’s lymphoma tumor model, SCR7 (20 mg/kg, i.p.) exhibits neither tumor regression nor increase in lifespan. In BALB/c mice, SCR7 (20 mg/kg, i.p.) significantly enhances the cytotoxic effects of radiation, VP-16213 and 3-Aminobenzamide on tumor derived from Dalton’s lymphoma (DLA) cells.[1]

Protocol (from reference)

Kinase Assay:

[1]
  • Complementation of SCR7 Inhibition with Purified Ligase IV

    Complementation experiment is carried out by adding increasing concentrations of purified Ligase IV/XRCC4 complex (30, 60, and 120 fmol) along with the oligomeric DNA substrates (5’ compatible and 5’-5’ noncompatible ends) to the SCR7-treatedextracts. Reactions are incubated for 2 h at 25℃. The reaction products are then resolved on 8% denaturing PAGE. The gel is dried and exposed and the signal is detected with a PhosphorImager and analyzed with Multi Gauge (V3.0) software.
Cell Assay:

[1]
  • Cell lines

    MCF7, CEM, HeLa, A549, HT1080, A2780, T47D, Nalm6, N114 and K562 cells

  • Concentrations

    250 μM

  • Incubation Time

    48 h

  • Method

    Cell proliferation of cancer cells are determined by MTT and trypan blue assays. Briefly, MCF7, CEM, HeLa, A549, HT1080, A2780, T47D, Nalm6, N114 and K562 cells are grown in presence of SCR7 (10, 50, 100, and 250 μM) for 24 or 48 h, and subjected to MTT or trypan blue assays. Each experiment is repeated a minimum of three independent times.
Animal Study:

  • Animal Models

    BALB/c mice

  • Dosages

    10 mg/kg

  • Administration
