Resumen

Polymere Nanopartikel sind ein vielversprechender Ansatz für die Diagnose und Therapie von Krankheiten. Sie ermöglichen den Einsatz von schwerlöslichen oder instabilen Wirkstoffen. Ein weiterer Vorteil ist die Möglichkeit das Targetings, durch gezielte Modifikationen des Nanopartikels wird der Wirkstoff zum Zielort transportiert und kann dort in der gewünschten Form freigesetzt werden; dadurch könnten bei erhöhter Wirksamkeit die Nebenwirkungen von Medikamenten reduziert werden. Ziel dieser Arbeit war die Untersuchung von physikalischen und biochemischen Eigenschaften von Nanopartikeln besteh

Resumen

Cette thèse a exploré l'intégration de moteurs moléculaires synthétiques photoactivables dans des réseaux de gels supramoléculaires. L'objectif principal était d'obtenir un mouvement macroscopique réversible en exploitant à la fois la rotation unidirectionnelle des moteurs moléculaires et la nature réversible des interactions supramoléculaires. Des moteurs moléculaires hautement fonctionnalisés ont été synthétisés et intégrés comme unités de réticulation dans des réseaux de gel supramoléculaire de peptides de diphénylalanine et de poly(γ-benzyl-L-glutamate) et d'oligonucléotides d'ADN.

In questa tesi sono stati affrontati tre progetti indipendenti, accomunati dall’uso della modellistica molecolare e in particolare della dinamica molecolare. Nel primo progetto è stato studiato il dominio Sec14-PH della neurofibromina (NF1). I domini sec14 sono stati scoperti in numerose proteine dai procarioti all’uomo come scambiatori di lipidi tra membrane, per mezzo di una tasca la cui apertura è legata al movimento di una specifica alpha-elica (elica lid).

Resumen

Mass spectrometry has in recent years been established as the standard method for protein identification and characterization in proteomics with excellent intrinsic sensitivity and specificity. Fourier transform ion cyclotron resonance is the mass spectrometric technique that provides the highest resolving power and mass accuracy, increasing the amount of information that can be obtained from complex samples. This thesis concerns how useful information on proteins of interest can be extracted from mass spectrometric data on different levels of protein structure and how to obtain this data expe

Aβ is a 39-43 amino acid polypeptide derived from proteolytic cleavages of the β-amyloid precursor protein (APP) by β- and γ-secretase. There are three groups of mutation sites in APP found in AD patients. These mutation sites locate near the ?, β- and γ-secretase cutting sites. It is believed that mutations near the β- and γ-secretase cutting sites induce a

Copper binding to Aβ has been hypothesized to play an important role in the neruotoxicity of Aβ. However, many properties of copper binding to Aβ have not been elucidated clearly, and the location of copper binding sites on Aβ is also in controversy.
