Methylglyoxal and advanced glycation endproducts: new therapeutic horizons?
Desai K, Wu L.. Recent patents on cardiovascular drug discovery, 2007-06-01
Topic: Brain proteins, microglia and lab models
Plain-language summary
Advanced glycation endproducts (AGEs) are unavoidable byproducts of various metabolic pathways. They are formed by reactive metabolic intermediates such as methylglyoxal (MG), glyoxal, and 3-deoxyglucosone. These reactive intermediates bind to proteins, DNA, and other molecules and disrupt their structures and functions, which leads to different diseases such as vascular complications of diabetes, atherosclerosis, hypertension, Alzheimer's disease, and aging. In recent years, more compounds that prevent the formation of AGEs or degrade the existing AGEs have been produced and patented. They include: 1) aminoguanidine, 2) drugs used in the treatment of type 2 diabetes such as metformin and pioglitazone (patented), 3) angiotensin receptor blockers and angiotensin converting enzyme inhibitors, 4) pentoxyfylline (patented), 5) metal ion chelators desferoxamine and penicillamine, 6) antioxidants such as vitamin C or E, 7) amino group capping agents such as aspirin, 8) enzymes that cause deglycation of Amadori products, the Amadoriases, 9) compounds that mostly break alpha-dicarbonyl cross-links such as phenacylthiazolium bromide and its stable derivative ALT-711 (Alagebrium), and 10) derivatives of aryl ureido and aryl carboxaminido phenoxy isobutyric acids (patented). While some of these anti-AGE compounds are being used in clinical practice (such as metformin, pioglitazone, pentoxyfylline and aspirin) or tested in clinical trials (such as aminoguanidine and ALT-711), most of them are commonly used as experimental tools to investigate the role of AGEs in different disease conditions.

Key findings
- They are formed by reactive metabolic intermediates such as methylglyoxal (MG), glyoxal, and 3-deoxyglucosone.
- These reactive intermediates bind to proteins, DNA, and other molecules and disrupt their structures and functions, which leads to different diseases such as vascular complications of diabetes, atherosclerosis, hypertension, Alzheimer's disease, and aging.
- In recent years, more compounds that prevent the formation of AGEs or degrade the existing AGEs have been produced and patented.
- They include: 1) aminoguanidine, 2) drugs used in the treatment of type 2 diabetes such as metformin and pioglitazone (patented), 3) angiotensin receptor blockers and angiotensin converting enzyme inhibitors, 4) pentoxyfylline (patented), 5) metal ion chelators desferoxamine and penicillamine, 6) antioxidants such as vitamin C or E, 7) amino group capping agents such as aspirin, 8) enzymes that cause deglycation of Amadori products, the Amadoriases, 9) compounds that mostly break alpha-dicarbonyl cross-links such as phenacylthiazolium bromide and its stable derivative ALT-711 (Alagebrium), and 10) derivatives of aryl ureido and aryl carboxaminido phenoxy isobutyric acids (patented).
- While some of these anti-AGE compounds are being used in clinical practice (such as metformin, pioglitazone, pentoxyfylline and aspirin) or tested in clinical trials (such as aminoguanidine and ALT-711), most of them are commonly used as experimental tools to investigate the role of AGEs in different disease conditions.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
