摘要:
The present invention provides a Ge adsorbent for a 68 Ge- 68 Ga generator, which is a polysaccharide polymer having a glucamine group represented by the formula (1) or the formula (2), wherein R 1 is a hydrogen atom or an alkyl group, and * is a bonding position.
摘要:
There is provided a composition comprising a compound represented by general formula (I), wherein R 1 represents a 5-iodothiophen-2-yl group or the like, and R 2 represents a 4-dimethylaminophenyl group or the like. This composition is useful for diagnosis of an amyloid-related disease such as Alzheimer's disease because the compound has high binding specificity to amyloid β protein, high permeability through the blood-brain barrier, and a property of being rapidly eliminated from sites other than senile plaques in the brain.
