HG-9-91-01
HG-9-91-01 is a pan-SIK (salt-inducible kinases) inhibitor with IC50 values of 0.92nM, 6.6nM and 9.6nM for SIK1, SIK2, SIK3, respectively [1].
SIKs restrict the formation of regulatory macrophages. The inhibition of these enzymes is thought to have potential for treating inflammatory and autoimmune diseases. HG-9-91-01 potently inhibits SIKs through targeting both the ATP-binding site and the small hydrophobic pocket. It is reported that, besides SIKs, HG-9-91-01 also inhibits various protein tyrosine kinases such as Src, BTK, FGF and Ephrin receptors. But other AMPK-related kinase subfamily members are not sensitive to HG-9-91-01. HG-9-91-01 can promote LPS-stimulated IL-10 production, CREB-dependent gene transcription, inhibit proinflammatory cytokine secretion and induce the expression of regulatory macrophage markers [1].

Applications |
HG-9-91-01increases LPS-stimulated IL-10 production and markedly inhibits proinflammatory cytokine secretion even when WT SIK2 is expressed to the same level. In addition, CRTC3 is required for HG-9-91-01 to enhance IL-10 production in LPS-stimulated primary mouse macrophages. |
