Borohydride
Borohydride — A reducing agent (NaBH₄) used in peptide chemistry for selective reduction reactions, including reductive amination and aldehyde reduction.
What Is Borohydride?
Sodium borohydride (NaBH4) and sodium cyanoborohydride (NaBH3CN) are reducing agents used in peptide chemistry for reductive amination (aldehyde + amine → secondary amine) and for reducing specific functional groups. NaBH3CN is selective (reduces imines but not aldehydes at neutral pH), making it ideal for site-specific peptide conjugation.
Applications
- Reductive amination: Attach peptide to aldehyde-functionalized surfaces or polymers
- N-terminal modification: Selective reductive alkylation of N-terminal amine with aldehydes
- Disulfide reduction: NaBH4 reduces disulfide bonds, though TCEP and DTT are preferred for selectivity
