title: A novel semisynthetic route to insulin analogues modified at the N-terminus of the A-chain.
abstract: We report a novel route for the semi-synthetic production of insulin analogues modified at the amino-terminus of the A-chain. The route proceeds from insulin via [Nalpha-Boc-GlyA1]-insulin to [Nalpha-(Z-methionyl)-PheB1, Nepsilon-(Z-methionyl)-LysB29]des-GlyA1-insulin. We have replaced residue A1 with glycine, to give a fully crystalline resynthesized insulin, and with D-lysine.
