WebCu(II) induced a reduction in tyrosine fluorescence of A (1– 42) at 307 nm (Fig. 1B), indicating that there is an interaction between Cu(II) and A . When coincubated with cyc-KLVFF, A (1–42) in the presence of Cu(II) exhibited greater fluores-cence (Fig. 1B), indicating that the cyc-KLVFF may have removed the Cu(II) from the A . WebIn the study, hydrophobic interactions and π–π stacking interactions facilitate porphyrin–peptide conjugate (PP-KLVFF) self-assembly into spherical nanostructured PKNPs and inhibit their fluorescence emission and ROS generation.

Self-Assembly and Anti-Amyloid Cytotoxicity Activity of

WebBy combining KLVFF peptide and self-assembly chaperone we fabricate a new system to achieve the synchronization between Aβ fibril disaggregation and reducing toxicity of Aβ fragments (monomers or oligomers) that consequently formed. When the KLVFF peptides disaggregate fibrils into fragments, the hydrophobic Celebrating the ChemComm … Webcomplex’–aproductthatdoesnotfluoresce.Fluorescence intensitydecreases withsteadystatequenchingas: 6 36 where K s is the association constant of the quencher and the fluorophore.

WebThus, to promote and observe these aggregations via fluorescence, the authors selected BP as the hydrophobic core. Because RGD naturally binds to integrin α v β 3, Ca 2+ coordination can regulate the self-assembly of BKR.
