Yum, Ji Hye;Ishizuka, Takumi;Fukumoto, Koyuki;Hori, Daisuke;Bao, Hong-Liang;Xu, Yan;Sugiyama, Hiroshi;Park, Soyoung research published 《 Systematic Approach to DNA Aptamer Design Using Amino Acid-Nucleic Acid Hybrids (ANHs) Targeting Thrombin》, the research content is summarized as follows. Chem. modifications of innate DNA/RNA aptamers facilitate the improvement of their function. Herein, we report our modular strategy to manipulate a thrombin-binding DNA aptamer (TBA) to improve its anticoagulation activity and binding affinity. A set of amino acid conjugates, termed amino acid-nucleic acid hybrids or ANHs, was synthesized and incorporated into a TBA loop sequences. We found that substitutions with hydrophobic amino acids in the loop region possessed significantly enhanced antithrombin activity, up to 3-fold higher than the native TBA. We investigated the correlations between thrombin-binding affinity and the features of our amino-acid conjugates using exptl. techniques including CD spectroscopy, surface plasmon resonance assay, and mol. modeling. The present study demonstrates a systematic approach to aptamer design based on amino-acid characteristics, allowing the development of advanced aptamers.
Electric Literature of 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., 35737-15-6.
