Efficient Loading of Sulfonamide Safety-Catch Linkers by Fmoc Amino Acid Fluorides
摘要:
[GRAPHICS]Fmoc-protected amino acid fluorides were found to be excellent reagents for the acylation of sulfonamide safety-catch linkers (SCL) suitable for the subsequent preparation of peptide C-terminal thioesters. High loadings were obtained on different types of resins with low levels of epimerization.

Novelchiral selectors based on 3,5‐dimethylphenylcarbamoylatedβ‐cyclodextrin connecting quinine (QN) or quinidine (QD) moiety were synthesized and immobilized on silica gel. Their chromatographic performances were investigated by comparing to the 3,5‐dimethylphenylcarbamoylatedβ‐cyclodextrin (β‐CD) chiralstationaryphase (CSP) and 9‐O‐(tert‐butylcarbamoyl)‐QN‐based CSP (QN‐AX).

generation of downstream anti-inflammatory effects. Peptides that mimic the β-turn in the Keap1 active site and are constrained by a disulfide bridge have high affinity for Keap1 but no intracellular activity. The introduction of a perfluoroalkyl-bridging group to constrain the peptides, coupled with a glutamic acid to proline replacement leads to a new peptide with a Ki of 6.1 nM for the Nrf2/Keap1 binding

Chemical synthesis of peptides can allow the option of sequential formation of multiple cysteines through exploitation of judiciously chosen regioselective thiol‐protectinggroups. We report the use of 2‐nitroveratryl (oNv) as a new orthogonal group that can be cleaved by photolysis under ambient conditions. In combination with complementary S‐pyridinesulfenyl activation, disulfide bonds are formed
