Amlexanox (AA673; Amoxanox; CHX3673) is a specific inhibitor ofIKKεandTBK1, and inhibits theIKKεandTBK1activity determined by MBP phosphorylation with anIC₅₀of approximately 1-2 μM.

Amlexanox increases phosphorylation of TBK1 on Ser172 in 3T3-L1 adipocytes, and blocks polyinosinic:polycytidylic acid (poly I:C)-stimulated phosphorylation of interferon responsive factor-3 (IRF3), a presumed substrate of IKKε and TBK1^[1]. Amlexanox potently inhibits the release of histamine and leukotrienes from mast cells, basophils and neutrophils in in vitro settings, possibly through increasing intracellular cyclic AMP content in inflammatory cells, a mem-brane-stabilising effect or inhibition of calcium influx^[2]. In primary bone marrow derived macrophages (BMMs), amlexanox inhibits osteoclast formation and bone resorption. At the molecular level, amlexanox suppresses RANKL-induced activation of nuclear factor-κB (NF-κB), mitogen-activated protein kinase (MAPKs), c-Fos and NFATc1. Amlexanox decreases the expression of osteoclast-specific genes, including TRAP, MMP9, Cathepsin K and NFATc1^[3].

Amlexanox (100 mg/kg, p.o.) prevents and reverses diet-induced or genetic obesity, and produces reversible weight loss in obese mice. Amlexanox also causes a significant decrease in adipose tissue mass in these mice, and an increase in circulating adiponectin. Amlexanox (25 mg/kg) significantly improves insulin sensitivity in mice with established DIO, and after four weeks of treatment, amlexanox produces marked improvements in glucose^[1]. Amlexanox before the first application of the paste and at each has been shown to suppress both immediate and evaluation thereafter. A categorical scale is also delayed-type hypersensitivity reactions^[2]. Amlexanox (20 mg/kg) enhances osteoblast differentiation of BMSCs. In ovariectomized (OVX) mouse model, amlexanox prevents OVX-induced bone loss by suppressing osteoclast activity^[3].
