There is provided a composition comprising a compound represented by general formula (I), wherein R
l
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.

01 μm and 13.18, respectively. PAMPA assays for all compounds were carried out in order to evaluate the capacity of the compounds to cross the blood-brain barrier. Moreover, the most potent MAO-B inhibitor, TB5, was found to be nontoxic at 5 and 25 μm, with 95.75 and 84.59 % viability among cells, respectively. Molecular docking simulations were carried out to understand the crucial interactions responsible

lamino)phenyl]prop-2-en-1- one is revealed by using single crystal X-ray diffraction study. The conformation of the molecule in solid state is used to carry out the drug design studies like structure optimization by Density Functional Theory (DFT) and Induced Fit Docking (IFD) study on human aldose reductase. The asymmetric unit of (2E)-1-(5-bromothiophen-2-yl)-3-[4- (dimethylamino) phenyl]prop-2-en-1-one
A series of novel chalcones and their related derivatives were synthesized and evaluated as beta-amyloid imaging probes. In the structure-activity relationship of binding affinities to synthetic A beta(1-42) aggregates, compound 14 displayed the highest binding affinity in vitro. Amyloid plaques in the Alzheimer's model mouse brain were visualized with 14. In biodistribution studies using normal mice, [I-125]14 showed good brain uptake (2.56% ID/g, 2 min postinjection) and rapid washout from the brain (0.21% ID/g, 60 min postinjection). These results suggest that [I-125]14 should be further investigated as a potentially useful P-amyloid imaging probe.
