Biological Activity

Description GNF-2 is a highly selective non-ATP competitive inhibitor of Bcr-Abl, shows no activity to Flt3-ITD, Tel-PDGFR, TPR-MET and Tel-JAK1 transformed tumor cells.
Targets
Bcr-Abl (SUP-B15 cell line) [1] Bcr-Abl (K562 cell line) [1]
268 nM 273 nM
In vitro GNF-2 causes a dose-dependent growth inhibition of the Bcr-abl–positive cell lines with IC50 values of 273 nM (K562) and 268 nM (SUP-B15). GNF-2 inhibits the growth of Ba/F3.p210E255V and Ba/F3.p185Y253H cells with IC50 values of 268 nM and 194 nM respectively. GNF-2 (1 μM) induces apoptosis of Ba/F3.p210 cells as well as Ba/F3.p210E255V cells. GNF-2 inhibits the cellular tyrosine phosphorylation of Bcr-abl in a dose-dependent manner with IC50 of 267 nM. GNF-2 (1 μM) induces a significant decrease in the levels of phospho-Stat5 in Ba/F3.p210 cells. GNF-2 binds to the myristic binding pocket of Bcr-abl. [1] GNF-2 inhibits the kinase activity of non-myristoylated c-Abl more potently than that of myristoylated c-Abl by binding to the myristate-binding pocket in the C-lobe of the kinase domain. GNF-2 (10 μM) requires BCR and/or the c-Abl SH3 and/or SH2 domains to inhibit BCR-Abl-dependent cell proliferation. GNF-2, but not a methylated GNF-2 analog, binds c-Abl in cellular extracts derived from 3T3 fibroblasts. GNF-2 (10 μM), in a dose-dependent manner, clearly inhibits tyrosine phosphorylation of CrkII. GNF-2 inhibits the phosphorylation of CrkII in c-AblG2A-expressing cells with IC50 of 0.051 μM. [2] GNF-2 binds in an extended conformation in the myristate pocket with the CF3-group buried at the same depth as the final two carbons of the myristate ligand. GNF-2 (10 µM) combined with imatinib (1 µM) reduces the number of resistant clones to 1 µM imatinib by at least 90%. [3] GNF-2 inhibits the auto-phosphorylation and proliferation of BafF3 cells expressing p210Bcr–Abl and p210Bcr–Abl mutants. GNF-2 (8 nM) in combination with GNF-5 (20 nM) results in additive effects with respect to inhibition of the Abl64–515 kinase activity. [4]

Protocol (from reference)

Kinase Assay:[2]
  • Binding assay

    Recombinant proteins (100 nM for each construct) or immunoprecipitated proteins are diluted in kinase buffer (20 mM HEPES (pH 7.4), 50 mM KCl, 0.1% CHAPS, 30 mM MgCl2, 2 mM MnCl2, 1 mM DTT, and 1% glycerol). Aliquots of the diluted proteins are preincubated with either DMSO or compounds for 30 min at room temperature and then added to K-LISA PTK EAY reaction plates. The kinase reaction is initiated by adding 0.1 mM ATP and is allowed to proceed for 30 min at room temperature. The phosphorylation of GST-Abltide is monitored by SDS-PAGE and phosphorimaging analysis or autoradiography.

Cell Assay:[1]
  • Cell lines

    Ba/F3.p210, Ba/F3.p210E255V and Ba/F3.p185Y253H cells

  • Concentrations

    ~10 μM

  • Incubation Time

    48 hours

  • Method

    Cells (0.3-0.6 × 106 per mL) are plated in duplicate or triplicate in 96-well plates containing increasing GNF-2 concentrations (5 nM–10 μM). After incubation at 37 ℃ in 5% CO2 for 48 hours, the effect of GNF-2 on cell viability is determined by the MTT colorimetric dye reduction method. Inhibition of cell proliferation is calculated as a percentage of growth of DMSO-treated cells, and IC50 values are determined with Microsoft Excel XLfit3.
