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. Recommanded Product: Fmoc-Trp-OH.
Yin, Huawu;Zhou, Xiuman;Huang, Yen-Hua;King, Gordon J.;Collins, Brett M.;Gao, Yanfeng;Craik, David J.;Wang, Conan K. research published 《 Rational Design of Potent Peptide Inhibitors of the PD-1:PD-L1 Interaction for Cancer Immunotherapy》, the research content is summarized as follows. Peptides have potential to be developed into immune checkpoint inhibitors, but the target interfaces are difficult to inhibit. Here, we explored an approach to mimic the binding surface of PD-1 to design inhibitors. Mimicking native PD-1 resulted in a mimetic with no activity. However, mimicking an affinity-optimized PD-1 resulted in the peptide mimetic MOPD-1 that displayed nanomolar affinity to PD-L1 and could inhibit PD-1:PD-L1 interactions in both protein- and cell-based assays. Mutagenesis and structural characterization using NMR spectroscopy and X-ray crystallog. revealed that binding residues from the high affinity PD-1 are crucial for the bioactivity of MOPD-1. Furthermore, MOPD-1 was extremely stable in human serum and inhibited tumor growth in vivo, suggesting it has potential for use in cancer immunotherapy. The successful design of an inhibitor of PD-1:PD-L1 using the mimicry approach described herein illustrates the value of placing greater emphasis on optimizing the target interface before inhibitor design and is an approach that could have broader utility for the design of peptide inhibitors for other complex protein-protein interactions.
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., Recommanded Product: Fmoc-Trp-OH
