Soft Template Mediated Peptide Crystallisation

Descrizione del progetto

Mantenere i peptidi in sequenza potrebbe consentire nuove potenti terapie

Le proteine sono onnipresenti nel corpo umano e svolgono un’enorme varietà di funzioni critiche, tra cui la segnalazione a breve e lunga distanza, il trasporto, la conservazione e il supporto strutturale. Queste molecole grandi e complesse sono costituite da unità molto più piccole chiamate peptidi. Lo sfruttamento di queste subunità naturali più semplici ma potenti offre buone prospettive per le terapie. Tuttavia, i loro vantaggi rispetto ai farmaci basati su piccole molecole sono difficili da definire, se si considerano le loro conformazioni flessibili e mutevoli in soluzione e la loro breve emivita. Il progetto ASPIRATION, finanziato dall’UE, intende sviluppare strategie basate su modelli per cristallizzare i peptidi al fine di aumentare la stabilità e la biodisponibilità del prodotto e migliorare la producibilità.

Obiettivo

Peptides are recognised for being highly selective and efficacious signalling molecules that bind to the specific cell surface receptors or ion channel where they trigger intracellular effects. They are relatively safe compared to small molecule-based drugs and are well tolerated in the human body. Peptide therapeutics exhibits an excellent opportunity in the pharmaceutical industry as their target specificity is much better than small molecules drugs, while the production cost and complexity are lower than protein-based biopharmaceuticals. In the past decade, peptide therapeutics have gained a wide range of applications in medicine and biotechnology. Currently, there are more than 60 US Food and Drug Administration (FDA) approved peptides medicine on the market and this is expected to grow significantly with 140 peptide drugs in the clinical trials and more than 500 peptide drugs in pre-clinical phase. Despite several advantages of peptide drugs, poor physical and chemical stability, and a short circulating plasma half-life are major issues related to the peptide drugs. Furthermore, these issues could be easily resolved by determining and studying the crystal forms of the peptides. Crystalline peptide not only improves the physical and chemical stability of the peptides but also improves processability and reduces the production cost. This action aims to introduce a peptide crystallisation method based on a soft template strategy where peptide building blocks i.e. amino acids or other short peptides will act as templates for the crystallisation of peptide drugs. This will be a low cost and scalable approach for crystallising peptides and gaining insight into the structural determination of peptides. Also, an in-depth understanding of the thermodynamic and kinetic processes that drive the crystallization for a specific peptide is required before the critical process parameters can be altered to achieve control over nucleation and crystal growth.
