Fmoc-Pen(Trt)-OH

Description:

Fmoc-Pen(Trt)-OH, or 9-fluorenylmethoxycarbonyl-L-penicillamine (with the CAS number 201531-88-6), is a protected amino acid commonly used in peptide synthesis. It features a fluorenylmethoxycarbonyl (Fmoc) group, which serves as a protective group for the amino functionality, allowing for selective deprotection during synthesis. The presence of the Trt (trityl) group provides additional protection for the thiol side chain of penicillamine, enhancing stability and preventing unwanted reactions. This compound is typically utilized in solid-phase peptide synthesis, where the Fmoc group can be easily removed under basic conditions, facilitating the sequential addition of amino acids. Fmoc-Pen(Trt)-OH is characterized by its relatively high stability under standard laboratory conditions, making it suitable for various synthetic applications. Its unique structure allows for the incorporation of sulfur-containing residues into peptides, which can be crucial for the formation of disulfide bonds and the overall stability of peptide structures. As with many chemical substances, proper handling and storage conditions are essential to maintain its integrity and reactivity.

Fmoc-S-trityl-L-penicillamine

CAS: 201531-88-6

Fmoc-S-trityl-L-penicillamine is a coordination compound that contains a thiolate and amide group. It has been used as a model system for studying the interaction between proteins and metal ions, with the cyclic structure mimicking the active site of enzymes. The coordination of Fmoc-S-trityl-L-penicillamine to proteins is affected by trypsin, an enzyme that cleaves peptides at carboxyl side chains. Trypsin can also lead to dehydration of Fmoc-S-trityl-L-penicillamine, forming an eliminations product. This compound also reacts with lysine residues in proteins, resulting in an alkene byproduct that can be removed by hydrogenation.
