A Convenient Synthesis of Short α-/β-Mixed Peptides as Potential α-Amylase Inhibitors.

ABSTRACT: Over the last decades, the increased incidence of metabolic disorders, such as type two diabetes and obesity, has motivated researchers to investigate new enzyme inhibitors. Inhibition of the α-amylase enzyme is one therapeutic approach in lowering glucose levels in the blood to manage diabetes mellitus. The objective of this study was to synthesize short α-/β-mixed peptides in the solution phase. The Boc-protected α-L-leucine was converted to β-analogue by using Arndt-Eistert synthesis with the advantage of no racemization and retention of configuration. Three novel short peptides were successfully synthesized: N(Boc)-Gly-β-Leu-OCH₃(14), N(Boc)-O(Bz)α-Ser-β-Leu-OCH₃(16), and N(Boc)-O(Bz)-α-Tyr-α-Gly-β-Leu-OCH₃(17), characterized by FTIR and ¹H N
