A pyridine ring contains several C–H bonds with relatively similar properties. Nevertheless, deprotonative metalation using sterically hindered metal amide bases often exhibits high regioselectivity, and changing the metalation system can markedly shift the site of reaction.
Bisabolol is a common soothing ingredient in cosmetics for sensitive-skin care, after-sun care, post-shave care, and skin-repair products. It is closely associated with German chamomile and can also be obtained from the Brazilian Candeia tree. Commercial production routes now include chemical ...
Bone remodeling depends on the dynamic coupling between new bone formation by osteoblasts and old bone removal by osteoclasts. ALP, TRAP, Cathepsin K, and MMPs participate in the establishment of the mineralization environment, osteoclast maturation, collagen degradation, and matrix remodeling, ...
Oats have long been used in the care of dry, sensitive, and itch-prone skin. In addition to starch, β-glucan, lipids, proteins, and other components, oats contain a group of low-abundance but clearly bioactive small molecules known as avenanthramides, which are also commonly referred to as ...
Bone metabolism is a dynamic process involving continuous coordination among bone formation, bone resorption, and mineralization, thereby maintaining the stability of bone mass, bone microarchitecture, and mechanical properties. Estrogen deficiency, long-term glucocorticoid exposure, aging, ...

Ring systems can influence the conformational constraints, three-dimensional shape, local electronic distribution, and spatial organization of substituents in drug molecules. Once a ring scaffold is incorporated into a complete molecule, its atomic composition, connectivity topology, and ...
Blockers reduce the functions of ion channels, membrane transporters, or nonspecific molecular interactions and can be used to investigate transmembrane currents, neurotransmitter transport, and interference in immunoassays. Their modes of action include pore blockade, gating modulation, ...
Both fasting and ketogenic diets can enhance fatty acid utilization and ketone body production. AMPK–MNK–eIF4E signaling and 5′UTR-dependent selective translation participate in this nutritional adaptation and influence the ability of pancreatic cancer to adapt to a ketogenic metabolic ...
