| Outline of Final Research Achievements |
Carnosine (β-alanyl histidine) is a small dipeptide abundantly present in the muscloes and brains. Carnosine has numerous beneficial characteristics, including the maintenance of the acid-base balance, antioxidant, metal chelating, anti-crosslinking, and anti-glycation activities. We investigated the neuroprotective effects of carnosine and the related compounds, and found that carnosine attenuated zinc-induced neurodegeneration, which plays central roles in the pathogenesis of vascular dementia. Furthermore, carnosine and its analogue anserine inhibited zinc-induced endoplasmic reticulum (ER)-stress, and attenuated the neurotoxicity induced by ER-stress inducers such as thapsigargin. We developed a convenient method to quantify the amount of carnosine using HPLC equipped with the carbon column, and investigated the amount of carnosine and anserine in various foods or in muscles of Thoroughbred horses. Our results are useful in the development of drugs for vascular dementia.
