Head-to-head comparison of AICAR and Alagebrium (ALT-711) — mechanism, dosing, side effects, legal status, and pricing.
AICAR (acadesine / AICA riboside) is a purine nucleoside analog and AMP-mimetic — not a peptide — that activates AMPK. Studied in registered human trials under the name acadesine (for cardioprotection and leukemia, not performance), it is not FDA-approved for any indication and is WADA-prohibited at all times. It is sold on the gray market as an "exercise mimetic."
Alagebrium (ALT-711) is a thiazolium-derived non-peptide small molecule investigated as an advanced glycation end-product (AGE) crosslink breaker. It reached Phase I–III human trials (2001–2010) for diastolic heart failure and hypertension but was never approved; clinical development was discontinued around 2009 due to financial constraints. No validated human dose exists. Currently sold by research-chemical vendors for research use only.

As acadesine, AICAR was tested in registered human trials by IV infusion: the large RED-CABG cardioprotection trial (JAMA 2012) was stopped for futility, and a Phase I/II study in relapsed/refractory CLL established 210 mg/kg IV as the optimal dose. No human trial evaluated AICAR for exercise, fat loss, or longevity, and no validated non-IV dosing exists. Not FDA-approved; not a peptide.
Key references
Alagebrium reached Phase I–III human trials (2001–2010) under sponsor Alteon Inc./Synvista Therapeutics but was never approved. A 16-week open-label pilot in 23 elderly patients (21 completers) with diastolic heart failure showed reduced left ventricular mass and improved Doppler diastolic index (E') without change in blood pressure, ejection fraction, or exercise capacity. The SPECTRA trial (ALT-711 + hydrochlorothiazide in hypertension) was terminated; the BENEFICIAL trial (chronic heart failure) was completed but did not meet efficacy endpoints. Preclinical studies in non-diabetic hypertensive rats, aged dogs, aged monkeys, streptozotocin-induced diabetic rats, and diabetic mouse models demonstrated improved vascular/cardiac function, reduced aortic stiffness, decreased collagen crosslinking, and improved renal pathology. A 2-year rat toxicology study found liver alterations that prompted a temporary enrollment suspension pending review.
AICAR and Alagebrium (ALT-711) 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.
