Abstract

With the advance of aging, Alzheimer's disease (AD) is creating unsustainable challenges to healthcare and economy in China and worldwide. Recent researches demonstrated that the mechanism of AD involves a multiple of metabolic disorders, i.e. metallostasis, insulin resistance, neuroinflammation, alteration of mitochondria, and changes of blood brain barrier (BBB) function, linked with each other in the core mechanism of amyloid plaque and neurobrillary tangles (NFT). Strong evidences indicated that each of the major protein participants in AD pathology has physiologically important interactions with transition metals. The amyloid pathology causes disorders of metal homeostasis in neurons, which inversely aggravate AD progress. Metal-based drugs/agents are of great potential in AD diagnosis and therapy, i.e. (ⅰ) probes for early AD diagnosis, (ⅱ) metal ligands and/or complexes modulating metallostasis, (ⅲ) anti-diabetic metal complexes, and (ⅳ) BBB and neuron protective metal compounds.
