Despitethe extensive use of gold as a π-bond activator, its applicationin redox catalysis for achieving cross-coupling reactions has historicallylagged behind. The primary obstacle in advancing gold redox catalysisis the inherent high redox potential of the Au(I)/Au(III) couple,arising from the pronounced relativistic effect. The instability ofAu(III) complexes due to facile reduction to gold nanoparticles presentsan additional challenge. Over the years, extensive efforts were madeto overcome these limitations which led to the identification of severalstrategies to achieve gold redox catalysis. These strategies primarilyrely on the use of external oxidants, photocatalyst/light, aryldiazoniumsalts, hemilabile ligands, electricity and dinuclear gold-complexesto facilitate Au(I)/Au(III) catalysis. Banking on these strategies,gold redox catalysis has emerged as a promising technique for varioustransformations such as cross-coupling reactions, C-H functionalizationreactions and difunctionalization of C-C multiple bonds. Interestingly,the high electronegativity and π-acid character of gold complexesoffer unique reactivities and selectivities compared to commonly usedtransition metals for cross-coupling reactions. Clearly, the fieldof Au(I)/Au(III) catalysis has significantly expanded the utilityof gold in organic synthesis and its applications in biological andmaterials science.

In these conditions, specific proteins misfold and accumulateinto insoluble aggregates, disrupting normal cellular function andcontributing to disease progression. Many studies have investigatedthe molecular mechanisms that underlie the aggregation pathways, thestructure of aggregates, such as oligomeric intermediates and fibrils,and their cellular toxicity. Studies have also investigated the effectsof cofactors like metals, lipids, other amyloid proteins, and smallmolecules. Recent research has increasingly emphasized the criticalroles of metal ions such as copper (Cu), zinc (Zn), iron (Fe), andmanganese (Mn) in amyloid aggregation and toxicity. Alterations inmetal ion transport, binding, or redox activity have been linked tothe onset and progression of several amyloid-associated diseases.These metal ions can interact directly with amyloidogenic proteins,influencing their structural conformation, aggregation kinetics, andpropensity to form toxic oligomers. This review aims to advance ourunderstanding of how the regulation of metal ions within cells andtheir dysfunction contribute to the accumulation of harmful proteins,which is a key factor in proteinopathies. By examining the interactionsbetween metal ions and key amyloidogenic proteins─includingamyloid-β (Aβ), α-synuclein, tau, superoxide dismutase1 (SOD1), human islet amyloid polypeptide (hIAPP), and insulin─wehighlight both common and unique pathways through which metal ionsinfluence protein aggregation. Additionally, this review exploresthe impact of metal ions on protein clearance mechanisms, such asautophagy and the ubiquitin–proteasome system, as well as emergingtheranostic strategies. These include metal chelation therapies, metal-basedimaging agents, and multifunctional compounds designed to restoremetal balance while preventing aggregation and toxicity.
