CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishSolid Phase Peptide Synthesis (SPPS) is a key technology for the production of pharmaceutical grade peptides, although it represents the worst modality in the pharma segment when considering its Process Mass Intensity (PMI). Consequently, academic and industrial research teams have focused their attention on greening SPPS protocols by introducing more sustainable alternatives to the most common reagents and solvents. In this context, 3-(diethylamino)propylamine (DEAPA) was identified to be a viable alternative to piperidine for Fmoc removal. In addition, the use of DEAPA in N-octyl-pyrrolidone (manual synthesis) or N-octyl pyrrolidone/dimethyl carbonate 8/2 v/v (automated synthesis) was proved to be able to minimize the formation of side products like diastereoisomers and aspartimide-containing derivatives.
