  • Interaction between Src and FAK during ILTV infection in LMH cells. The protein levels of FAK, phosphorylated FAK (p-FAK), Src, and phosphorylated Src (p-SRC) were assayed in LMH cells with or without ILTV infection upon pretreatment with SU6656. β-Tubulin or β-actin was used as a loading control. The intensity ratio between the corresponding bands (upper band/lower band) was determined using ImageJ and normalized to the ratio of DMSO.

    H, Adriamycin-treated cells were cultured for 23 h in the presence of cytochalasin D to inhibit cytokinesis. The numbers of binucleated cells were counted, and the mitotic index was determined in parallel. N, nucleus.

  • (B) IP3 levels measured by ELISA in CD36OE and vector control of HepG2.2.15 and HepAD38 cells (n = 3) (*P < 0.05). (C) Src kinase inhibitor (SU6656) decreases cytosolic Ca2+ in CD36OE of HepG2.2.15 and HepAD38 cells. SU6656 or vehicle controls (DMSO) were added to the CD36OE of HepG2.2.15 and HepAD38 cells for 24 h, Cytosolic Ca2+ was measured after treatment using flow cytometry (n = 3) (*** p < 0.001). (D) Src kinase inhibitor (SU6656) overrides the higher HBV replication induced by CD36 overexpression. SU6656 or vehicle controls (DMSO) were added to the CD36 overexpression of HepG2.2.15 and HepAD38 cells for 96 h. HBV DNA were extracted and detected by real-time PCR (n = 4). (**P < 0.01 and*** p < 0.001).

Biological Activity

Description SU 6656 is a selective Src family kinase inhibitor with IC50 of 280 nM, 20 nM, 130 nM, and 170 nM for Src, Yes, Lyn, and Fyn, respectively.

In vitro

In NIH 3T3 cells, SU 6656 inhibits the PDGF-stimulated S-phase induction with IC50 of 0.3-0.4 μM. SU 6656 also inhibits PDGF- and serum-mediated NIH 3T3 cell proliferation, as well as epidermal growth factor and colony-stimulating factor 1-stimulated DNA synthesis in normal and colony-stimulating factor 1 receptor transfected NIH 3T3 cells. SU6656 inhibits PDGF-stimulated c-Myc induction and ERK2 activation.[1] Pretreating Jurkat T-cells with SU 6656 leads to increased VSV-G luciferase activity.[2] SU 6656 impairs TGF-β-mediated upregulation of CTGF mRNA and protein in proximal epithelial HKC-8 cells, and also reduces CTGF expression in cells exposed to autocrine growth factors. SU 6656 interferes with Aurora kinase activity resulting in inhibition of cell division and formation multilobular nuclei.[3]

In vivo SU 6656 markedly and dose-dependently attenuates mecamylamine-induced experimental nicotine withdrawal syndrome in mice measured in terms of WSS and anxiety score.[4] Once-daily administration of SU 6656 (1.5, 3, and 6 mg/kg, i.p.) markedly and dose-dependently attenuates the naloxone-induced morphine withdrawal syndrome.[5]

Protocol

Kinase Assay:[1]
+ Expand

Biochemical kinase assays for IC50 determination and kinetic studies:

IC50 measurements are made using poly-Glu–Tyr (4:1), or, in the case of Lck, poly-Lys–Tyr (4:1) as a peptide substrate. The divalent cation is 20 mM MgCl2 (in the case of Src, Fyn, Yes, Lyn, Csk, Frk, or Abl) or 10 mM MnCl2 (in the case of FGFR1, IGF1R, Lck, or Met). The final ATP concentrations are as follows: Src, 10 μM; Fyn, 6 μM; Yes, 100 μM; Lyn, 2 μM; Csk, 10 μM; Frk, 10 μM; Abl, 4 μM; FGFR1, 10 μM; IGF1R, 2 μM; Lck, 2 μM; Met, 5 μM; PDGFR, 6 μM. IC50 measurements of PDGFRb autophosphorylation are determined on immunoprecipitated PDGFRb. Km values are calculated using the Eadie-Hofstee method.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
