Semapimod tetrahydrochloride (CNI-1493), an inhibitor of proinflammatory cytokine production, can inhibit TNF-α, IL-1β, and IL-6. Semapimod tetrahydrochloride inhibits TLR4 signaling (IC50≈0.3 μM). Semapimod tetrahydrochloride inhibits p38 MAPK and nitric oxide production in macrophages. Semapimod tetrahydrochloride has potential in a variety of inflammatory and autoimmune disorders[1][2][3].

In Vitro	Semapimod tetrahydrochloride 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 tetrahydrochloride completely abrogated nitric oxide production within the tunica muscularis[2]. Semapimod tetrahydrochloride 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 tetrahydrochloride desensitizes TLR signaling via its effect on the TLR chaperone gp96[3].
In Vivo	Semapimod tetrahydrochloride (5 mg/kg; i.p; daily for 2 weeks) ameliorates endothelial dysfunction in Obese Zucker (OZ) rats[1]. Semapimod tetrahydrochloride restores AM-induced akt phosphorylation and cGMP production in OZ rats[1]. Animal Model: Male OZ rats[1] Dosage: 5 mg/kg Administration: I.p; daily for 2 weeks Result: Restored endothelium-dependent vasorelaxation in OZ rats.
