Alzheimer’s disease (AD) is associated with progressive accumulation of amyloid-β (Aβ) cross-β fibrils in the brain. Aβ species tightly associated with GM1 ganglioside, a glycosphingolipid abundant in neuronal membranes, promote amyloid fibril

Mallory reaction of 1,2-bis(4-hydroxyphenyl)-3,3,4,4,5,5-hexafluorocyclopentene under light irradiation (λ = 356 nm) in the presence of iodine as an oxidant proceeded to give fluorine-containing phenanthrene bearing hydroxyl groups, 6,9-bis(4-hydrox

A one‐handed 310‐helical hexapeptide is efficiently encapsulated within the helical cavity of st‐PMMA when a fullerene (C60) derivative is introduced at the C‐terminal end of the peptide. The encapsulation is accompanied by induction of a pre

Poly-l-alanine (PLA) sequences are a key element in the structure of the crystalline domains of spider dragline silks, wild silkworm silks, antifreeze proteins, and amyloids. To date, no atomic-level structures of antiparallel (AP)-PLA longer than Al

A palladium-catalyzed alternating copolymerization of [2.2.1]oxabicyclic alkenes 1 with carbon monoxide afforded isomer mixtures of polyketones 2ktn and polyketals 2ktl. Subsequent acid-induced dehydration of polymer 2 furnished novel aromatic polyme

We have previously suggested that crystalline Bombyx mori silk in silk II form (the silk structure after spinning) is not a simple antiparallel β-sheet but is intrinsically heterogeneous. Using the peptide (AG)15, we have obtained the first fully as
