Nα-Fmoc-6-hydroxynorleucine (CAS 374899-60-2)

Nα-Fmoc-6-hydroxynorleucine is a compound utilized in peptide chemistry, particularly in the synthesis of modified peptides. The Nα-Fmoc (9-fluorenylmethyloxycarbonyl) group serves as a protective group for the amino function during solid-phase peptide synthesis (SPPS), allowing for the sequential addition of amino acids to the growing peptide chain. The hydroxyl group on the side chain of Nα-Fmoc-6-hydroxynorleucine provides an additional functional handle that can be further modified or participate in specific interactions within the peptide or protein structure. This non-standard amino acid is used to investigate the influence of hydroxylation on peptide stability, conformation, and biological activity. Researchers also explore its incorporation into peptides to study post-translational modifications, such as hydroxylation, which are significant in cellular processes and protein maturation. The use of Nα-Fmoc-6-hydroxynorleucine in peptide research contributes to a broader understanding of protein structure-function relationships.
