KC7F2 is a novel inhibitor of HIF-1αwith IC50 value of 20 μM [1].

Hypoxia inducible factor-1 (HIF-1) is a heterodimeric transcription factor consisting of α and β subunits. In normal situation, the HIF-1α subunit is constitutively translated, but rapidly degraded. While, under hypoxia it is stabilized. HIF target genes encode a series of critical factors to adapt the low oxygen [1].

In a HIF-reporter cell line LN229-HRE-AP, KC7F2 (>25 μM) reduced AP activity by 90% in LN229 cells, which indicated that KC7F2 inhibited AP enzyme activity. In LNZ308 human glioma cells, KC7F2 inhibited the expression of a panel of HIF target genes, such as matrix metalloproteinase 2 (MMP2), enolase 1, carbonic anhydrase IX (CA IX) and endothelin 1. Also, KC7F2 reduced expression of HIF-1α in a dose-dependent way [1].

In a rat epilepsy model, KC7F2 significantly shortened the latent period in the PTZ kindling model and increased the rate of spontaneous recurrent seizures during the chronic stage in the lithium-pilocarpine model [3].
