Identification of Toll-like receptor signaling inhibitors (SJ-18-0008)

St. Jude Reference #SJ-18-0008


Researchers at St. Jude and the University of Illinois at Urbana-Champaign have designed Toll-like receptor (TLR) signaling inhibitors useful in the treatment of diseases or conditions resulting from excessive activity of the Toll-like receptors. TLRs have been shown to play a role in the pathogenesis of many diseases, including autoimmunity, infectious and inflammatory diseases. Exaggerated or prolonged TLR activation leads to pathological inflammation and diverse diseases, such as bacterial sepsis, metabolic and autoimmune diseases, cancer or stroke.

This series of methyl-piperidino-pyrazole (MPP) compounds may be used for research involving blocking the TLR pathway, including in vivo research. Based on these studies and further research, optimized forms of these compounds may be used for treating patients.
