One of the molecular hallmarks of amyloidoses is ordered protein aggregation involving the initial formation of soluble protein oligomers that eventually grow into insoluble fibrils. The identification and characterization of molecular species critical fo ...
Described is a new class of small molecule inhibitors of amyloid beta protein (Abeta) aggregation, based on apomorphine. These molecules target the nucleation phase of Abeta self-assembly and interfere effectively with aggregation of Abeta 1-40 into amyloi ...
Protein misfolding and aggregation have been linked to several human diseases, including Alzheimer's disease, Parkinson's disease, and systemic amyloidosis, by mechanisms that are not yet completely understood. The hallmark of most of these diseases is the ...
The formation of amyloid aggregates is the hallmark of the amyloidogenic diseases. Transthyretin (TTR) is involved in senile systemic amyloidosis (wild-type protein) and familial amyloidotic polyneuropathy (point mutants). Through the use of high hydrostat ...
Analytical ultracentrifugation methods were utilized to further characterize the acid denaturation pathways of wild-type, V30M, and L55P transthyretin (TTR) that generate intermediates leading to amyloid fibril formation and possibly the diseases senile sy ...
Systemic amyloidosis is a heterogeneous group of diseases associated with protein misfolding into insoluble beta-sheet rich structures that deposit extracellularly in different organs, eventually compromising their function. There are more than 30 differen ...
Several amyloid-forming proteins are characterized by the presence of hydrophobic and highly amyloidogenic core sequences that play critical roles in the initiation and progression of amyloid fibril formation. Therefore targeting these sequences represents ...
Described is a new class of small molecule inhibitors of amyloid beta protein (Abeta) aggregation, based on apomorphine. These molecules target the nucleation phase of Abeta self-assembly and interfere effectively with aggregation of Abeta 1-40 into amyloi ...
The early stages of fibril formation are difficult to capture in solution. We use cold-ion spectroscopy to examine an 11-residue peptide derived from the protein transthyretin and clusters of this fibre-forming peptide containing up to five units in the ga ...
Twelve analogues of diclofenac (1), a nonsteroidal antiinflammatory drug and known inhibitor of transthyretin (TTR) amyloid formation, were prepared and evaluated as TTR amyloid formation inhibitors. High activity was exhibited by five of the compounds. St ...
