This thesis project describes the design and synthesis of innovative fluorescent probes with a 4,6-diaminopyrimidine scaffold of the proteins of the ErbB (erythroblastic leukemia viral oncogene homologue) / HER (Human Epidermal Growth Factor Receptor 2) family, which are part of the tyrosine kinases. , in particular towards the ErbB2/HER2 receptor. The first objective is to identify the cells that overexpress ErbB receptors (as potential tumor cells) compared to the cells that normally express them. The second objective is to identify the variations in the activation state of these ErbB receptors that lead to drug resistance phenomena. The preparation of these compounds was idealized by taking into consideration an interesting synthesis strategy, which allows these quinazoline scaffolds to be obtained starting from simple commercial anilines. The aforementioned strategy is based on the Heck synthesis, which is based on a palladium-catalyzed arylation reaction that is used to produce mono- and diaryl 1,3-dienes. All final synthesized molecules were characterized by proton nuclear magnetic resonance spectrometry and mass spectrometry.
In questo progetto di tesi vengono descritte la progettazione e la sintesi di innovative sonde fluorescenti a scaffold 4,6-diamminopirimidinico delle proteine della famiglia ErbB (erythroblastic leukemia viral oncogene homologue) / HER (Human Epidermal Growth Factor Receptor 2), facenti parte delle tirosinchinasi, in particolare nei confronti del recettore ErbB2/HER2. Il primo obiettivo è di individuare le cellule che sovraesprimono i recettori ErbB (in quanto potenziali cellule tumorali) rispetto alle cellule che li normoesprimono. Il secondo obiettivo è di identificare le variazioni dello stato di attivazione di tali recettori ErbB che portano ai fenomeni di farmacoresistenza. La preparazione di questi composti è stata idealizzata prendendo in considerazione un’interessante strategia di sintesi, la quale permette di ottenere, a partire da semplici aniline commerciali, questi scaffold chinazolinici. Suddetta strategia è basata sulla sintesi di Heck, la quale si basa su una reazione di arilazione catalizzata dal palladio che viene impiegata per produrre mono- e diaril 1,3-dieni. Tutte le molecole finali sintetizzate sono state caratterizzate mediante spettrometria di risonanza magnetica nucleare del protone e mediante spettrometria di massa.

The first objective is to identify the cells that overexpress ErbB receptors (as potential tumor cells) compared to the cells that normally express them. The second objective is to identify the variations in the activation state of these ErbB receptors that lead to drug resistance phenomena. The preparation of these compounds was idealized by taking into consideration an interesting synthesis strategy, which allows these quinazoline scaffolds to be obtained starting from simple commercial anilines.
