Fmoc-D-Asn(Trt)-OH: A Critical Component in Peptide Synthesis and Drug Development
The intricate world of peptide synthesis relies on specialized chemical building blocks, and Fmoc-D-Asn(Trt)-OH (CAS 180570-71-2) stands as a crucial pharmaceutical intermediate in this domain. This protected amino acid derivative is essential for constructing complex peptide chains, playing a significant role in both academic research and the development of peptide-based therapeutics.
Fmoc-D-Asn(Trt)-OH is a chemically modified form of D-asparagine. The molecule features the Fmoc (9-fluorenylmethoxycarbonyl) protecting group on its alpha-amino group and the trityl (Trt) protecting group on its side-chain amide. These protecting groups are strategically employed in solid-phase peptide synthesis (SPPS) to ensure controlled and selective coupling reactions. The Fmoc group is readily removed under mild basic conditions, allowing for the sequential addition of amino acids to a growing peptide chain. The trityl group provides robust protection for the side chain, which is typically cleaved during the final stages of synthesis, releasing the desired peptide.
The inclusion of the D-isomer of asparagine in Fmoc-D-Asn(Trt)-OH is particularly significant. Peptides that incorporate D-amino acids often exhibit enhanced resistance to proteases, enzymes that degrade peptides in biological environments. This improved stability means that peptides synthesized using Fmoc-D-Asn(Trt)-OH can have longer circulatory half-lives, leading to more sustained therapeutic effects. This characteristic is highly desirable in the development of peptide drugs, as it can improve their efficacy and potentially reduce the frequency of administration.
As a key pharmaceutical intermediate, Fmoc-D-Asn(Trt)-OH is widely used by researchers in drug discovery and development. Its application spans the synthesis of peptide hormones, neuropeptides, and various peptide-based drugs targeting a multitude of diseases. The consistent availability of high-purity Fmoc-D-Asn(Trt)-OH from reputable manufacturers and suppliers is crucial for the smooth progression of these research and development efforts.
When seeking to acquire Fmoc-D-Asn(Trt)-OH, it is important to prioritize purity and reliability. Suppliers often provide detailed specifications, with high purity levels (typically ≥99% by HPLC) being a standard requirement. Manufacturers, including those based in China, offer this intermediate, contributing to the global supply chain for peptide synthesis reagents. The price of Fmoc-D-Asn(Trt)-OH can vary based on factors such as the scale of purchase and the specific supplier, but investing in quality ensures the integrity of the final peptide product.
In conclusion, Fmoc-D-Asn(Trt)-OH (CAS 180570-71-2) is a vital component for modern peptide synthesis. Its protective groups and the incorporation of a D-amino acid make it an indispensable tool for creating stable, biologically active peptides. Its role as a key pharmaceutical intermediate underscores its importance in the ongoing advancements in peptide-based drug development.
