HG-12-6 is a type II inhibitor of IRAK4. HG-12-6 shows preferential binding to unphosphorylated inactive IRAK4 (IC50: 165 nM). HG-12-6 can modulate IRAK4 activity in autoimmunity and inflammation.
Syk-IN-4 is a potent, selective, and orally bioavailable inhibitor of SYK, demonstrating an IC50 of 0.31 nM. It targets SYK, which has been identified as a potential therapeutic target for autoimmunity and hematological cancers[1].
