Synthetic pTH(1-84): comparing sustainability between SPPS, NCL and CEPS

by Leendert van den Bos (CEO and Co-Founder EnzyTag) and Stefan Eissler (VP Peptide Manufacturing at Bachem)

Parathyroid hormone (pTH), also called parathormone or parathyrin, is a peptide hormone secreted by the parathyroid glands that regulates the serum calcium concentration through its effects on bone, kidney, and intestine (ref Wikipedia). This contribution will compare various synthetic routes towards pTH on several sustainability parameters incl. overall yields, solvent consumption, scalability and atom efficiency. The synthetic routes that will be discussed are straight-trough SPPS, fragment condensation using Native Chemical Ligation and fragment condensation using Chemo-Enzymatic Peptide Synthesis (ref Peptiligase). The comparison will be based on gram scale synthesis data.
