High-throughput screening has shown that Retro-1 inhibits ricin and Shiga toxins by diminishing their intracellular trafficking via the retrograde route, from early endosomes to the Golgi apparatus To improve the activity of Retro-1, a structure-activity relationship (SAR) study was undertaken and yielded an analog with a roughly 70-fold better half-maximal effective concentration (EC₅₀) against Shiga toxin cytotoxicity measured in a cell protein synthesis assay.

COA of Formula: C26H22N2O4, 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., 35737-15-6.

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. COA of Formula: C26H22N2O4.

Abboud, Skander A.;Amoura, Mehdi;Madinier, Jean-Baptiste;Renoux, Brigitte;Papot, Sebastien;Piller, Veronique;Aucagne, Vincent research published 《 Enzyme-cleavable linkers for protein chemical synthesis through solid-phase ligations》, the research content is summarized as follows. The total synthesis of long proteins requires the assembly of multiple fragments through successive ligations. The need for intermediate purification steps is a strong limitation, particularly in terms of overall yield. One solution to this problem would be solid-supported chem. ligation (SPCL), for which a first peptide segment must be immobilized on a SPCL-compatible solid support through a linker that can be cleaved under very mild conditions to release the assembled protein. The cleavage of SPCL linkers has previously required chem. conditions sometimes incompatible with sensitive protein targets. Herein, we describe an alternative enzymic approach to trigger cleavage under extremely mild and selective conditions. Optimization of the linker structure and use of a small enzyme able to diffuse into the solid support were key to the success of the strategy. We demonstrated its utility by the assembly of three peptide segments on the basis of native chem. ligation to afford a 15 kDa polypeptide.

Jacob, Biju;Datta, Riya research published 《 Synthesis, characterization and antimicrobial studies of novel Schiff bases and their complexes》, the research content is summarized as follows. Novel Schiff bases, Furan-2-carboxylic acid pyridin-4-ylmethyleneamide, and Thiophene-2-carboxylic acid 1H-indol-2-ylmethyleneamide and their mononuclear Ni(II) and Cu(II) complexes have been synthesized and characterized by elemental anal., molar conductance, UV-visible, FT-IR, ¹H NMR and EPR spectroscopy. The complexes are nonelectrolytes as evidenced from the molar conductance vaules. The ligands and their complexes have been tested for their antimicrobial activity against one gram pos. bacteria, Bacillus subtilis, gram neg. bacteria, Escherichia coli and fungi Candida albicans. It is found that metal complexes exhibited more activity than the free ligand.
