Protecting Groups

Protecting Groups

Protecting groups are used in organic synthesis to temporarily mask reactive functional groups, allowing selective reactions to occur without interference. These groups are essential for multi-step synthesis processes, ensuring that specific parts of the molecule remain unreactive while other reactions are performed. In this section, you will find a variety of protecting groups suitable for different functional groups, along with reagents for their introduction and removal. At CymitQuimica, we offer a comprehensive range of high-quality protecting groups to facilitate your synthetic strategies.

  • Fmoc-N-Me-Asp(OtBu)-OH

    CAS:
    Fmoc-N-Me-Asp(OtBu)-OH is a synthetic peptide with potential immunosuppressive properties. It has been shown to inhibit the proliferation of human lymphocytes in response to lipopolysaccharides (LPS) and also to suppress the release of cytokines such as IL-1β, IL-6, and TNFα. The effects were dose dependent and could be reversed by the addition of a neutralizing antibody. This peptide can be used as an immunosuppressant in clinical trials that are investigating treatments for myasthenia gravis. Fmoc-N-Me-Asp(OtBu)-OH has been synthesised using chemical synthesis methods from commercially available reagents.

  • Fmoc-glycinol

    CAS:
    Fmoc-glycinol is a synthetase that is used to synthesize glycinol conjugates. It binds to the receptor on Gram-positive bacteria and blocks the synthesis of bacterial cell wall, leading to cell death. Fmoc-glycinol has been shown to have high binding constants with amines and an acyl chain, which allows it to bind with antigen. Fmoc-glycinol also has strong nucleophilic properties that allow it to react with chloride ions in water and other polar solvents. This reaction mechanism leads to the formation of a new bond between two molecules, which is called a glycinol linkage.

  • Boc-D-Tyr(tBu)-OH

    CAS:
    Boc-D-Tyr(tBu)-OH is a natural product that is an amphipathic molecule with a cyclic structure. It has been shown to be able to inhibit the growth of bacteria, such as Staphylococcus aureus and Escherichia coli, by acting as an antibiotic. Boc-D-Tyr(tBu)-OH inhibits the synthesis of peptides by binding to the ribosome and blocking peptide elongation. This molecule also inhibits peptide synthesis by interacting with the aminoacyl site on the ribosome and preventing it from binding with amino acids. Boc-D-Tyr(tBu)-OH is synthesized in two stages: solid phase peptide synthesis and nucleophilic activation. The decapeptides are then purified and characterized based on their function.
