Semapimod
Based on 4 publication(s) in Google Scholar
Semapimod, an inhibitor of proinflammatory cytokine production, can inhibit TNF-α, IL-1β, and IL-6. Semapimod inhibits TLR4 signaling (IC50≈0.3 μM). Semapimod inhibits p38 MAPK and nitric oxide production in macrophages. Semapimod has potential in a variety of inflammatory and autoimmune disorders.

Semapimod leads to a significant decrease of p38-MAPK phosphorylation in macrophages, proinflammatory gene expression of macrophage inflammatory protein-1alpha, interleukin-6, monocyte chemoattractant protein-1, and intercellular adhesion molecule-1, and neutrophil infiltration. Semapimod completely abrogated nitric oxide production within the tunica muscularis[2].
Semapimod desensitizes TLR signaling via its effect on the TLR chaperone gp96. Semapimod tetrahydrochloride inhibits ATP-binding and ATPase activities of gp96 in vitro (IC50≈0.2-0.4 μM). Semapimod desensitizes TLR signaling via its effect on the TLR chaperone gp96[3].
Semapimod (0-500 nM) inhibits microglia-stimulated GL261 invasion[4].
Semapimod (0-10 µM) dose not affect serum-stimulated glioblastoma cell invasion, even at 10 µM, underlining the selectivity of semapimod for cells from the monocytic lineage[4].
Semapimod (200 nM) does not affect microglia-stimulated glioblastoma cell proliferation[4].

Semapimod restores AM-induced akt phosphorylation and cGMP production in OZ rats[1].
Semapimod (6 mg/kg/day, Intracranially for 1 week) inhibits glioblastoma cell invasion in vivo[4].
Semapimod (intracranially administered, 2 weeks) semapimos strongly increases the survival of GL261 tumor-bearing animals in combination with radiation, but has no significant benefit in the absence of radiation[4].
