Optically Active Fmoc-Protected β-Hydroxy-α-amino Acid (Serine) Derivatives

Chiral Building Blocks for Peptide Synthesis and Drug Discovery Research


Optically active Fmoc-protected β-hydroxy-α-amino acid derivatives are highly valuable chiral building blocks for peptide and medium-sized molecule drug discovery. β-Hydroxy-α-amino acid residues are key structural motifs found in numerous peptide natural products and peptide-based therapeutics, including vancomycin. Leveraging proprietary technology developed by the Institute of Microbial Chemistry (BIKAKEN), we have successfully commercialized a unique series of non-natural serine derivatives possessing two contiguous stereogenic centers—compounds that have previously been difficult to obtain.

The chiral building blocks are developed and supplied by proprietary technologies
from Institute of Microbial Chemistry (Bikaken).
 

Key Features

• Ready for Direct Use in Solid-Phase Peptide Synthesis (SPPS):
  These N-Fmoc-protected amino acid derivatives, the most widely used protecting group strategy for SPPS, are supplied with the side-chain hydroxyl group also protected, enabling their direct use in peptide synthesis and in the preparation of amino acid analogues and derivatives.
   
• High-Quality Chiral Reagents:
  All products meet stringent quality standards with chemical purity >95% and optical purity >95% ee, making them reliable chiral building blocks for synthetic applications.
   
• A Unique Product Line Enabled by Proprietary Catalytic Technology:
  Utilizing the highly stereoselective direct catalytic asymmetric aldol reaction¹ developed by the Institute of Microbial Chemistry (BIKAKEN), we have established a stable supply of diverse non-natural amino acid derivatives with a wide variety of side-chain structures. These products are ideal for expanding peptide drug discovery libraries and for the exploration of novel amino acid derivatives.
