KG-501

Synonyms: 2-naphthol-AS-E-phosphate

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.

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.

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].

Cell Research 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.

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].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
