What is it about?

A China-U.S. study led by scientists at China Pharmaceutical University (CPU) and Harvard University has identified a new small-molecule antagonist of the stimulator of interferon genes (STING) signaling pathway, SN-011, and shown it to be safe, effective and specific in STING-driven inflammatory diseases.

Why is it important?

SN-011 was demonstrated to inhibit activation of wild-type (WT) and SAVI-associated STING GOF mutants. SN-011 was not only well tolerated, but also shown to ameliorate autoimmune pathology and significantly prevent death in Trex1-deficient mice. It potentially could be improved for treating inflammatory and auto-immune diseases.


The SN-011 could be served as a starting point for developing drugs, which are instrumental for treating a broad range of inflammatory diseases, concerning various pathological organs
