Biological Activity

Description

KC7F2 is a selective HIF-1α translation inhibitor with IC50 of 20 μM in a cell-based assay.

Targets

HIF-1α ^[1]

20 μM

In vitro
In vitro	KC7F2 inhibits HIF-1α protein synthesis but not its mRNA transcription. KC7F2 inhibits HRE-driven transcription and decreases HIF-1α protein levels in LN229-HRE-AP cells. KC7F2 shows a dose-response cytotoxicity with IC50 of approximately 15 to 25 μM in cancer cells MCF7, LNZ308, A549, U251MG, and LN229. In D54MG glioma cells, KC7F2 inhibits colony formation, especially under hypoxia. ^[1] In hypoxic microglial cultures, KC7F2 downregulates the expression of TfR and DMT, and reduces the HIF-1α mediated iron accumulation. ^[2]
Kinase Assay	HIF transcriptional activity assay
Kinase Assay	Cells are incubated at 37癈 in a humidified atmosphere containing 5% CO₂ and 21% O₂ (normoxia) or 1% O₂ (hypoxia) in a hypoxia workstation. The LN229-HRE-AP reporter cell line for HIF transcriptional activity is created by stably transfecting LN229 cells with the pACN188 plasmid, which contains an alkaline phosphatase gene driven by six HREs derived from the VEGF gene.
Cell Research	Cell lines	Human dermal microvascular endothelial cells and mouse neurons; MCF7, LNZ308, A549, U251MG, and LN229 cell lines
	Concentrations	72 h
	Incubation Time	20 μM
	Method	Cells are seeded onto 96-well plates (4 × 10³/well) and cultured under normoxic (21% O₂) and hypoxic (1% O₂) conditions with different concentrations of KC7F2 for 72 h or treated for various times with 20 μM KC7F2. For proliferation analysis, cells are fixed with 50% trichloroacetic acid for 1 h at 4°C, followed by staining with 0.4% sulforhodamine B dissolved in 1% acetic acid for 30 min at room temperature. Plates are washed five times with 1% acetic acid to remove unbound dye. Bound dye is dissolved by adding 10 mM unbuffered Tris base. Cell proliferation is calculated by measuring OD values at 564 nm using a spectrophotometer.

In Vivo
In vivo	KC7F2 significantly reduces the latent period in the pentylenetetrazole kindling rat model and increases the rate of spontaneous recurrent seizures during the chronic stage. ^[3]
