Σχεδιασμός και σύνθεση πεπτιδομιμητών ως αναστολείς της οικογένειας Μ1 αμινοπεπτιδασών ψευδαργύρου
Περίληψη σε άλλη γλώσσα
This dissertation focuses on the design and synthesis of peptidomimetic inhibitors targeting zinc-dependent metalloproteases of the M1 family, specifically the Endoplasmic Reticulum Aminopeptidases ERAP1 and ERAP2, as well as the Insulin-regulated Aminopeptidase IRAP. These enzymes play a critical role in immune system regulation by degrading antigenic precursors and facilitating antigen presentation. The study employed Structure Activity Relationship (SAR) strategies, utilizing computational models to predict interactions between inhibitors and enzyme active sites. Inhibitors were designed based on the (2S,3R)3-amino-2-hydroxy acid scaffold of Bestatin, which acts as a weak ligand for the catalytic Zn(II) ion in the active sites of the enzymes. Exploration of the S1 binding pocket of the enzymes was performed by modifying the R1 substituents. Additionally, appropriate substituents were introduced at the R1' and R2' positions, derived from natural and non-natural L-amino acid chains. T ...
