 Use of HG-12-6


HG-12-6 is a small-molecule inhibitor that bind preferentially to unphosphorylated IRAK4 with IC50 of 165.1 nM, displays 15-fold selectivity over phosphorylated IRAK4 (IC50=2876 nM); binds as type II inhibitor with IRAK4 in a “DFG-out” conformation.

In Vitro The in-house compound HG-12-6 has a similar chemical scaffold as Ponatinib. The most differentiating components are the head of the inhibitor and the lack of a methyl substituent on ring A. Without the methyl substituent on ring A, the entire HG-12-6 molecule shifts inward to the ATP pocket in comparison with the binding mode of Ponatinib[1]. HG-12-6 has a better binding affinity for the unphosphorylated inactive IRAK4 kinase domain (IC50 of 165 nM) than the phosphorylated active IRAK4 kinase domain (IC50 of 2876 nM)[1].
