Amlexanox is a specific inhibitor of IKKε and TBK1. Amlexanox blocked IKKε activity with a half maximal inhibitory concentration of approximately 1–2 μM. Amlexanox increased phosphorylation of TBK1 on Ser172 in 3T3-L1 adipocytes. Mice treated with amlexanox concurrently with HFD had improved glucose tolerance, with an approximate 30–40% reduction in the area under the curve for glucose. After a 100mg dose of 5% amlexanox topical paste, applied directly to the lesion, the maximum serum concentration of the drug was 120 ng/mL, which was achieved 2.4 hours after application.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
