Submit ReviewSC 144 hydrochloride
Description: gp130 inhibitor; blocks cytokine-triggered gp130 signaling
Chemical Name: 2-(7-Fluoropyrrolo[1,2-a]quinoxalin-4-yl) 2-pyrazinecarboxylic acid hydrazide hydrochloride
Purity: ≥98% (HPLC)
Biological Activity
Inhibitor of gp130 (IC50 = 0.72 μM); blocks cytokine-triggered gp130 signaling. Induces gp130 phosphorylation and down regulates gp130 glycosylation; also abrogates STAT3 phosphorylation, nuclear translocation and inhibits the expression of downstream target genes. Delays tumor growth in a mouse xenograft model of human ovarian cancer. Orally active.
Compound Libraries
SC 144 hydrochloride is also offered as part of the Tocriscreen 2.0 Max and Tocriscreen Antiviral Library. Find out more about compound libraries available from Tocris.

Asthma Poster
Asthma is one of the most common chronic diseases in the world, affecting over 300 million people. This poster highlights key pathways and new therapies used to treat the condition, including those currently in clinical development.
Pain Poster
Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
Rheumatoid Arthritis Poster
Rheumatoid arthritis (RA) is a chronic destructive inflammatory autoimmune disease that results from a breakdown in immune tolerance, for reasons that are as yet unknown. This poster summarizes the pathology of RA and the inflammatory processes involved, as well as describing some of the epigenetic modifications associated with the disease and the potential for targeting these changes in the discovery of new treatments.
