Artificial Protein Assemblies Induced by Metal Coordination Interaction

Effect of metal catalyzed oxidation in recombinant viral protein assemblies

BACKGROUND Protein assemblies, such as virus-like particles, have increasing importance as vaccines, delivery vehicles and nanomaterials. However, their use requires stable assemblies. An important cause of loss of stability in proteins is oxidation, which can occur during their production, purification and storage. Despite its importance, very few studies have investigated the effect of oxidat...

Apoptosis Induced by Metal Complexes and Interaction with Dexamethasone

Apoptosis induced by rhodium II amidate, rhodium II propionate, cisplatin and interactions with dexamethaxone were studied on some human leukemia cell lines Raji, Jurkat and U937. Apoptosis was studied by flow cytometry, agarose gel electrophoresis and morphological analysis. Rhodium II propionate induced apoptosis in all the three cell lines, Rhodium II amidate, in the lymphoid cell lines Jurk...

Resonance interaction induced by metal surfaces catalyzes atom-pair breakage

P 97: Neurodegeneration Induced by Tau protein

Tau is one of several types of microtubule-associated proteins (MAPs), responsible for the assembly and stability of microtubule networks that is present only in neurons and predominantly localized in axons which its functions are tightly regulated by phosphorylation. Via as yet unknown mechanisms, tau becomes hyperphosphorylated and accompanies with neuronal degeneration, loss of synapses...

Combining hydrogen bonding and metal coordination for controlling topochemical [2 + 2] cycloaddition from multi-component assemblies.

The crystal engineering of hydrogen bonded metal assemblies based on stilbene-type compounds is exploited in order to drive [2 + 2] cycloaddition in the solid state. Harmonization of hydrogen bonding and metal coordination is shown as an alternative supramolecular approach for the rational design of novel supramolecular photoreactive networks. This approach was extended to prepare five compound...
