LW6 (HIF-1α inhibitor) (Synonyms: Hypoxia-Inducible Factor1α Inhibitor) |
| Catalog No.GC32724 |
LW6 (HIF-1α inhibitor) (HIF-1α inhibitor) is a novel HIF-1 inhibitor with an IC50 of 4.4 μM. LW6 (HIF-1α inhibitor) decreases HIF-1α protein expression without affecting HIF-1β expression.

Sample solution is provided at 25 µL, 10mM.
LW6 is a hypoxia-inducing factor 1(HIF) inhibitor, which effectively inhibits HIF-1α accumulation by degrading HIF-1α, but does not affect HIF-1A mRNA level during hypoxia. LW6 inhibits the expression of HIF and MDH2, with IC50 values of 4.4 and 6.3µM, respectively [1-2].
LW6(0.01-25µM ; 30 min) enhanced significantly the cellular accumulation of mitoxantrone(BCRP substrate)in MDCKII-BCRP cells (overexpressed BCRP)[3]. LW6 inhibited hypoxia-induced HIF1α expression at 20 mM in A549 cells, and at this concentration,LW6 induced hypoxia-selective apoptosis and decreased mitochondrial membrane potential[4]. LW6(40-160µM) inhibited proliferation and induced cell death in a dose-dependent manner In 6606PDA and MIA PaCa-2 cells[5]. LW6 (80µM)significantly inhibited migration,besides,LW6 reduced cell proliferation and induced cell death in a dose dependent manner[6]. LW6(30 µµ; 72 h) stimulates T cells to decrease HIF-1α levels[7]. LW6 inhibited T-cell clonal expansion in two-way mixed lymphocyte reaction (MLR) [8].
LW6(5 mg/kg;i.v/p.o) exhibited a small volume of distribution and a short terminal half-life. LW6 was slowly degraded in mouse liver microsomes and serum. About 54% or 44.8% of LW6 was available systemically as APA in the mouse after a single intravenous or oral administration, respectively[1].
