Biological Activity

Description KG-501 is a cAMP response element-binding protein (CREB) inhibitor that disrupts CREB-dependent transcription (Ki = 10 μM) and CREB:CBP interaction (Ki = 50 μM). It also disrupts phospho (Ser-133) CREB binding to KIX with a Ki of ≈90 μM, using concentrations of CREB that were within the linear range of the binding assay.
Targets
CREB [1]
In vitro

KG-501 inhibits induction of cAMP-responsive genes, at least in part, by blocking the CREB:CBP interaction[1]. The inhibition of the CREB pathway using KG-501, induces an inhibition of neurite outgrowth and synaptogenesis, as well as a decrease of MAP2+ neuronal cells[2].
In vivo

KG-501 inhibits CREB, CCL2 expression and ERK phosphorylation, also significantly lowers the cAMP level. CREB might contribute to the neuroprotection opposed neuroinflammation through cAMP/ERK adjustment pathway. KG-501 significantly promots the neurological outcomes of AOM-treated mice, reduces phosphorylation of ERK and the concentration of cAMP in cortex[3].

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    HEK293T cells

  • Concentrations

    5, 10, 25 μM

  • Incubation Time

    20 min

  • Method

    EVX-1 luciferase reporter plasmid was transfected into HEK293T cells. At 24 h posttransfection, cells were pretreated with the indicated amount of KG-501 or DMSO vehicle for 20 min followed by coincubation with forskolin or DMSO. Cells were harvested at 4 h, and luciferase activity was measured.
Animal Study:

[3]
  • Animal Models

    Murine azoxymethane (AOM) model of hepatic encephalopathy (Adult male C57BL/6 mice)

  • Dosages

    10, 20, or 50 μM

  • Administration

    intracerebroventricular infusion
