Amyloid β (Aβ) refers to peptides derived from Amyloid precursor protein that vary in length from 36-43 amino acids. Aβ(s) peptides, their peptide fragments and mutated fragments are used to study a wide range of metabolic and regulatory functions including activation of kinases, regulation of cholesterol transport, function as a transcription factor, and regulators of inflammation. Aβ(s) peptides and their peptide fragments are also used to study oxidative stress, metal binding and mechanisms of protein cross-linking in the context of diseases such as Alzheimer′s disease and neurodegeneration.
The reaction of the ruthenium(II) complex fac-[Ru(CO)(3)Cl(2)(N(1)-thz)] (I hereafter; thz = 1,3-thiazole) with human beta-amyloid peptide 1-28 (Abeta(28)) and the resulting {Ru(CO)(3)}(2+) peptide adduct was investigated by a variety of biophysical methods. (1)H NMR titrations highlighted a selective interaction of
Phosphorus Dendrimers Affect Alzheimer's (Aμ(1-28)) Peptide and MAP-Tau Protein Aggregation.
The reactions of human β-amyloid peptide 1-28 (Aβ28) with Al(III) and Fe(III) ions were investigated by (1)H NMR and electrospray ionization mass spectrometry (ESI-MS) under pH conditions close to physiological ones. (1)H NMR titrations, performed in the 5.3-8.0 pH range
