Head-to-head comparison of Amlexanox and SLU-PP-332 — mechanism, side effects, legal status, and pricing.
Amlexanox is a non-peptide small-molecule 2-amino-chromeno[2,3-b]pyridine-3-carboxylic acid derivative (CAS 68302-57-8, MW 298.29 g/mol). Originally approved in 1996 as a topical oral paste for aphthous ulcers (FDA, now discontinued) and in Japan for allergic conditions, it was later characterized as a selective ATP-competitive inhibitor of the non-canonical IκB kinases TBK1 and IKKε. It is NOT approved for any metabolic, obesity, or performance indication; it is sold by research-chemical vendors labeled research-use-only and promoted off-label by biohacking outlets for fat loss. No validated human dose exists for metabolic applications.
SLU-PP-332 is a small-molecule (non-peptide) pan-agonist of estrogen-related receptors ERRα/β/γ developed at Saint Louis University. Studied preclinically as an exercise mimetic in rodents, it has no human clinical data and is NOT FDA-approved. Sold only as a grey-market research chemical.

In diet-induced obese and ob/ob mice, amlexanox treatment increased energy expenditure via thermogenesis, produced weight loss, improved insulin sensitivity, and decreased hepatic steatosis; these metabolic benefits require intact FGF21 signaling. In LDL-receptor-knockout mice on Western diet, amlexanox reduced triglycerides, cholesterol, circulating monocytes/eosinophils, macrophage plaque accumulation, and atherosclerotic lesion size. One randomized, double-blind, placebo-controlled proof-of-concept trial in 42 obese patients with type 2 diabetes and NAFLD showed statistically significant HbA1c and fructosamine reductions versus placebo, with a responder subgroup showing improved insulin sensitivity and reduced hepatic fat; rash occurred in several participants (two required biopsy). No obesity or diabetes indication has been approved by any regulator.
Billon et al. (ACS Chemical Biology, 2023) reported that SLU-PP-332 in sedentary mice increased treadmill endurance, enhanced slow-twitch fiber content, boosted mitochondrial biogenesis, and conferred resistance to high-fat-diet weight gain without exercise training. A follow-up (Billon et al., J Pharmacol Exp Ther, 2024) showed benefits in mouse metabolic-syndrome models. Developed at Saint Louis University (Burris/Walker/Elgendy groups). Rodent/preclinical data ONLY — no human clinical trials have been initiated. Not FDA-approved; not a peptide.
Amlexanox and SLU-PP-332 are both in the Metabolic category and may have overlapping mechanisms. Researchers should review both profiles carefully, understand the mechanisms of action, and monitor the relevant biomarkers when combining compounds in the same class. As always, consult a licensed healthcare provider before making any decisions about combining research compounds.
