Indole, also called Benzopyrrole, a heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. 35737-15-6, formula is C26H22N2O4, Name is Fmoc-Trp-OH. It is used in perfumery and in making tryptophan, an essential amino acid, and indoleacetic acid (heteroauxin), a hormone that promotes the development of roots in plant cuttings. Formula: C26H22N2O4.
Wu, Yaqi;Li, Cong;Fan, Shihui;Zhao, Yibing;Wu, Chuanliu research published 《 Fast and selective reaction of 2-benzylacrylaldehyde with 1,2-aminothiol for stable N-terminal cysteine modification and peptide cyclization》, the research content is summarized as follows. N-terminal cysteine (Cys)-specific reactions have been exploited for protein and peptide modifications. However, existing reactions for N-terminal Cys suffer from low reaction rate, unavoidable side reactions, or poor stability for reagents or products. Herein we report a fast, efficient, and selective conjugation between 2-benzylacrylaldehyde (BAA) and 1,2-aminothiol, which involves multistep reactions including aldimine condensation, Michael addition, and reduction of imine by NaBH3CN. This conjugation proceeds with a rate constant of ~2700 M-1 s-1 under neutral condition at room temperature to produce a pair of seven-membered ring diastereoisomers, which are stable under neutral and acidic conditions. This method enables the selective modifications of the N-terminal Cys residue without interference from the internal Cys and lysine residues, providing a useful alternative to existing approaches for site-specific peptide or protein modifications and synthesis of cyclic peptides.
35737-15-6, Nalpha-FMOC-L-Tryptophan,also known as Fmoc-Trp-OH， is a useful research compound. Its molecular formula is C26H22N2O4 and its molecular weight is 426.5 g/mol. The purity is usually 95%.
Nα-Fmoc-L-Tryptophan is an N-Fmoc protected form of L-Tryptophan (T947210). L-Tryptophan is an essential amino acid that is important for cell proliferation and the biosynthesis of proteins. It is a precursor to Serotonin (HCl: S274980), a neurotransmitter that compound that aids in sleep and mental state. L-Tryptophan is also thought to cause eosinophilia-myalgia syndrome.
Fmoc-Trp-OH is an amino acid derivative
Fmoc-L-Trp-OH is an amide that contains a low bioavailability and inhibits the transfer of amino acids to ribosomes. It has been shown to inhibit the growth of cancer cells in cell culture and to have antimicrobial activity. Fmoc-L-Trp-OH is synthesized by reacting Naphthalene with glycine, followed by hydrolysis of the ester group under trifluoroacetic acid. The product is then conjugated with a polypeptide. This method of synthesis was developed as a way to produce peptides that are difficult to synthesize using solid-phase chemistry., Formula: C26H22N2O4
