Biological Activity

Description GNF-5 is a selective and allosteric Bcr-Abl inhibitor with IC50 of 220 nM.
Targets
Bcr-Abl [1]
220 nM
In vitro

GNF-5, when used in combination, suppresses the emergence of resistance mutations in vitro, and displays additive inhibitory activity in biochemical and cellular assays against Bcr-Abl T315I mutant. [1] GNF-5 shows potent antiproliferative activity with EC50 of 430 nM and 580 nM against wt-Bcr-Abl and E255K mutant Bcr-Abl transformed cells, respectively. [2]
In vivo

GNF-5 (100 mg/kg ) displays efficacy on wild-type and T315I Bcr-Abl dependent proliferation in xenograft and bone marrow transplantation models. Moreover, a combination of GNF-5 (75 mg/kg) results in improved overall survival in a T315I Bcr-Abl BMT model. [1]

Protocol (from reference)

Kinase Assay:

[1]
  • Kinetic characterization of Abl inhibition

    The ATP/NADH-coupled assay system in a 96-well format is used to determine the initial velocity of Abl tyrosine kinase catalyzed peptide phosphorylation. The reaction mixture contained 20 mM Tris-HCl, (pH 8.0), 50 mM NaCl, 10 mM MgCl2, 2 mM PEP [2-(Phosphonooxy)- 2-propenoic acid) and 20 μg Abl peptide substrate (EAIYAAPFAKKK), fixed or varied (to determine inhibitor kinetic parameters) concentration of inhibitor applied, 1/50 of the final reaction mixture volume of PK/LDH enzyme (pyruvate kinase/lactic dehydrogenase enzymes from rabbit muscle), 160 μM NADH, 0.16 μM Abl, and ATP added last to start the reaction. Absorbance data are collected every 20s at 340 nm using a SpectraMax M5 Microplate Reader.

Cell Assay:

[2]
  • Cell lines

    Ba/F3.p210 cells

  • Concentrations

    ~10 μM

  • Incubation Time

    48 hours

  • Method

    Ba/F3.p210 cells are obtained by transfecting the IL-3-dependent murine hematopoietic Ba/F3 cell line with a pEYK vector containing p210BCR-ABL and Bcr-Abl mutations. All cell lines are cultured with 5% CO2 at 37 °C in RPMI 1640 with 10% fetal bovine serum (FBS) and supplemented with 1% l-glutamine. Parental Ba/F3 cells are similarly cultured with 10% WEHI-conditioned medium as a source of IL-3. Transfected cell lines are cultured in media supplemented with 25 μg/mL zeocin. The 48 h cell proliferation studies are obtained using the CellTiter-Glo assay.
Animal Study:

  • Animal Models

    Ba/F3.p210 xenograft mouse model

  • Dosages

    ~100 mg/kg bid

  • Administration
