Definitions
- the present invention relates to a gadolinium-based compound and an MRI contrast agent containing the same.
- Degenerative brain diseases include Parkinson's disease, vascular dementia, Alzheimer's disease, and the like, and neurotoxicity due to excessive accumulation of amyloid beta polymer (oligomeric A ⁇ ) is considered as one of the causes of the disease.
- Amyloid beta is a major component of amyloid plaques found in the brains of Alzheimer's patients, and refers to a 36 to 43 amino acid peptide that is critically involved in Alzheimer's disease.
- the peptide is derived from amyloid precursor protein (APP).
- amyloid beta molecule can aggregate to form a soluble polymer that can exist in various forms.
