Previous studies have identified that indole-oxidases are present in P. putida, whose major ligands are heterocyclic substrates and have an interesting affinity when the substrate is indole. 35737-15-6, formula is C26H22N2O4, Name is Fmoc-Trp-OH. These enzymes oxidize the ring so the substrate turns into Indigo. Application of C26H22N2O4.
Jacobsson, Erik;Peigneur, Steve;Andersson, Haakan S.;Laborde, Quentin;Strand, Malin;Tytgat, Jan;Goeransson, Ulf research published 《 Functional Characterization of the Nemertide α Family of Peptide Toxins》, the research content is summarized as follows. Peptide toxins find use in medicine, biotechnol., and agriculture. They are exploited as pharmaceutical tools, particularly for the investigation of ion channels. Here, we report the synthesis and activity of a novel family of peptide toxins: the cystine-knotted α nemertides. Following the prototypic α-1 and -2 (1 and 2), six more nemertides were discovered by mining of available nemertean transcriptomes. Here, we describe their synthesis using solid phase peptide chem. and their oxidative folding by using an improved protocol. Nemertides α-2 to α-7 (2-7) were produced to characterize their effect on voltage-gated sodium channels (Blatella germanica BgNaV1 and mammalian NaVs1.1-1.8). In addition, ion channel activities were matched to in vivo tests using an Artemia microwell assay. Although nemertides demonstrate high sequence similarity, they display variability in activity on the tested NaVs. The nemertides are all highly toxic to Artemia, with EC50 values in the sub-low micromolar range, and all manifest preference for the insect BgNaV1 channel. Structure-activity relationship anal. revealed key residues for NaV-subtype selectivity. Combined with low EC50 values (e.g., NaV1.1: 7.9 nM (α-6); NaV1.3: 9.4 nM (α-5); NaV1.4: 14.6 nM (α-4)) this underscores the potential utility of α-nemertides for rational optimization to improve selectivity.
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., Application of C26H22N2O4
