K811
K811 is an orally active ASK1 inhibitor with an IC50 of 6 nM. K811 inhibits glial cell activation in the lumbar spinal cord of SOD1G93A transgenic mice. K811 extends the survival of SOD1G93A transgenic mice, a mouse model of amyotrophic lateral sclerosis. K811 can be used in studies related to amyotrophic lateral sclerosis.

K811 (1.0 μM; 30 min) inhibits H2O2-induced ASK1 activation in NSC34 motor neuron-like cells[1].
K811 (added 24 h after lentiviral infection and incubated until day 9 post-seeding) protects primary motor neurons from SOD1G93A-induced death in spinal cord cultures derived from E12.5 Hb9-GFP mouse embryos[1].

Concentration:1.0 μM
-
Incubation Time:30 min (pre-incubation); 15 min (H2O2 treatment)
-
Result:Significantly reduced the H2O2-induced activation of endogenous ASK1, as measured by decreased levels of phosphorylated ASK1 via immunoblotting.

Caused a considerable decrease in ASK1 activation in the spinal cord.
Increased the number of motor neurons in one side of the lumbar spinal cord significantly compared to placebo.
Decreased numbers of glial fibrillary acidic protein (GFAP)-positive astrocytes and ionized calcium binding adaptor molecule 1 (Iba1)-positive microglia markedly in the lumbar spinal cord compared to placebo.
