A simple and eco-friendly nano Fe₂O₃ heterogeneous catalytic system was described for the synthesis of acyl thiourea derivatives from corresponding in-situ generated acyl isothiocyanates and amino acid esters in acetone obtained in good yields. The structures of synthesized acyl thioureas were confimed by ¹H NMR, ¹³C NMR, mass and FTIR anal. Fe₂O₃ NPs was prepared via a solution combustion route using ascorbic acid as the reducing agent and ferric nitrate as the source of iron. The prepared nano material was characterized by XRD, SEM, UV-Visible and FTIR anal. More prominently, the Fe₂O₃ and other impurities were removed though a simple work-up and the material prepared showed to be effective in catalyzing the conversion of reactants to products in good yields. Further, some of the synthesized acyl thioureas were evaluated for in-vitro antibacterial activity against Staphylococcus aureus and Escherichia coli.

Malayam Parambath, Sreya;Williams, Ashley E.;Hunt, Leigh Anna;Selvan, Dhanashree;Hammer, Nathan I.;Chakraborty, Saumen research published 《 A De Novo-Designed Artificial Metallopeptide Hydrogenase: Insights into Photochemical Processes and the Role of Protonated Cys》, the research content is summarized as follows. Hydrogenase enzymes produce H₂ gas, which can be a potential source of alternative energy. Inspired by the [NiFe] hydrogenases, we report the construction of a de novo-designed artificial hydrogenase (ArH). The ArH is a dimeric coiled coil where two cysteine (Cys) residues are introduced at tandem a/d positions of a heptad to create a tetrathiolato Ni binding site. Spectroscopic studies show that Ni binding significantly stabilizes the peptide producing electronic transitions characteristic of Ni-thiolate proteins. The ArH produces H₂ photocatalytically, demonstrating a bell-shaped pH-dependence on activity. Fluorescence lifetimes and transient absorption spectroscopic studies are undertaken to elucidate the nature of pH-dependence, and to monitor the reaction kinetics of the photochem. processes. PH titrations are employed to determine the role of protonated Cys on reactivity. Through combining these results, a fine balance is found between solution acidity and the electron transfer steps. This balance is critical to maximize the production of Ni^I-peptide and protonation of the Ni^II-H^– intermediate (Ni-R) by a Cys (pK_a≈6.4) to produce H₂.

Malik, Uru;Chan, Lai Yue;Cai, Minying;Hruby, Victor J.;Kaas, Quentin;Daly, Norelle L.;Craik, David J. research published 《 Development of novel frog-skin peptide scaffolds with selectivity towards melanocortin receptor subtypes》, the research content is summarized as follows. Melanocortin receptors are pharmaceutically important receptors that are involved in complex physiol. functions. They have been associated with various diseases including obesity, erectile dysfunction, acne, and skin cancer. It has been challenging to transform nonselective endogenous agonist and antagonist ligands into selective and potent ligands. In this study, we investigated naturally occurring peptides derived from frog skin secretions for selectivity and activity toward melanocortin receptors. Three peptides (ORB, ORB2K and ranacyclin-T) were found to have selectivity towards the melanocortin receptor 5 (MC5R). ORB and ORB2K had partial binding affinity at nanomolar concentrations, whereas ranacyclin-T had 57% binding efficiency at 1.6μM. Backbone cyclization of ORB and ORB2K altered the binding efficiency to melanocortin receptors. Our results suggest that these frog-skin peptides could be modified for developing melanocortin-specific ligands and potentially future therapeutics.

Mallek, Aaron J.;Pentelute, Bradley L.;Buchwald, Stephen L. research published 《 Selective N-arylation of p-aminophenylalanine in unprotected peptides with organometallic palladium reagents》, the research content is summarized as follows. The selective N-arylation of p-aminophenylalanine in polypeptides with pre-formed palladium oxidative addition complexes is described. The depressed pKa of the aniline NH₂ group enables chemoselective C-N bond formation on peptides containing multiple other aliphatic amino groups at lysines or the N-terminus via Curtin-Hammett control under mild conditions. Using palladium complexes derived from electron-poor aryl halides, p-aminophenylalanine is fully arylated in aqueous buffer in as little as one hour at micromolar concentrations A complementary protocol using the non-nucleophilic, organic base 1,5-diazabicyclo(4.3.0)non-5-ene (DBN), expands the substrate scope to tolerate electron-rich functional groups provides up to 97% conversion. These procedures enable the chemoselective conjugation of functionally diverse small mol. pharmaceuticals to p-aminophenylalanine containing derivatives of cell-penetrating peptides.

Mao, Runyu;Xi, Shiyi;Shah, Sayali;Roy, Michael J.;John, Alan;Lingford, James P.;Gade, Gerd;Scott, Nichollas E.;Goddard-Borger, Ethan D. research published 《 Synthesis of C-mannosylated glycopeptides enabled by Ni-catalyzed photoreductive cross-coupling reactions》, the research content is summarized as follows. The biol. functions of tryptophan C-mannosylation are poorly understood, in part, due to a dearth of methods for preparing pure glycopeptides and glycoproteins with this modification. To address this issue, efficient and scalable methods are required for installing this protein modification. Here, we describe unique Ni-catalyzed cross-coupling conditions that utilize photocatalysis or a Hantzsch ester photoreductant to couple glycosyl halides with (hetero)aryl bromides, thereby enabling the α-C-mannosylation of 2-bromo-tryptophan, peptides thereof, and (hetero)aryl bromides more generally. We also report that 2-(α-D-mannopyranosyl)-L-tryptophan undergoes facile anomerization in the presence of acid: something that must be considered when preparing and handling peptides with this modification. These developments enabled the first automated solid-phase peptide syntheses of C-mannosylated glycopeptides, which we used to map the epitope of an antibody, as well as providing the first verified synthesis of Carmo-HrTH-I, a C-mannosylated insect hormone. To complement this approach, we also performed late-stage tryptophan C-mannosylation on a diverse array of peptides, demonstrating the broad scope and utility of this methodol. for preparing glycopeptides.

Disulfide-rich peptides and proteins are among the most fascinating bioactive mols. The difficulties associated with the preparation of these targets have prompted the development of various chem. strategies. Nevertheless, the production of these targets remains very challenging or elusive. Recently, we introduced a strategy for one-pot disulfide bond formation, tackling most of the previous limitations. However, the effect of the order of oxidation remained an underexplored issue. Herein we report on the complete synthetic flexibility of the approach with respect to the order of oxidation of three disulfide bonds in targets that lack the knot motif. In contrast, our study reveals an essential order of disulfide bond formation in the EETI-II knotted miniprotein. This synthetic strategy was applied for the synthesis of novel analogs of the plectasin antimicrobial peptide with enhanced activities against methicillin-resistant Staphylococcus aureus (MRSA), a notorious human pathogen.

The emergence of multidrug-resistant bacteria has dramatically increased the lethality, level of resistance, and difficulty of treatment. In this study, a series of new antimicrobial peptides (AMPs) based on the β-hairpin structure with the template (XY)₂RRRF(YX)₂-NH₂ (X: hydrophobic amino acids; Y: cationic amino acids) were synthesized; surprisin gly, almost all of the new peptides have strong antibacterial activity and negligible hemolytic toxicity. Particularly, the therapeutic index (TI) values of F(RI)2R and F(KW)2K reached up to 115.9 and 70.7, resp. In addition, they did not show induced drug resistance and inhibited the development of antibiotic resistance when combined and used with traditional antibiotics. In addition, their antibacterial mechanism was preliminarily studied. Moreover, the new peptides F(RI)2R and F(KW)2K showed excellent performance in the pulmonary bacterial infection model and low toxicity in mice. In conclusion, F(RI)2R and F(KW)2K are considered new antimicrobial alternatives to address the antimicrobial-resistance crisis.

Li, Xingyue;Sabol, Andrew L.;Wierzbicki, Michal;Salveson, Patrick J.;Nowick, James S. research published 《 An improved turn structure for inducing β-hairpin formation in peptides》, the research content is summarized as follows. Although β-hairpins are widespread in proteins, there is no tool to coax any small peptide to adopt a β-hairpin conformation, regardless of sequence. Here, we report that δ-linked γ(R)-methyl-ornithine (^δMeOrn) provides an improved β-turn template for inducing a β-hairpin conformation in peptides. We developed a synthesis of protected ^δMeOrn as a building block suitable for use in Fmoc-based solid-phase peptide synthesis (Fmoc = 9-fluorenylmethoxycarbonyl). The synthesis begins with L-leucine and affords gram quantities of the N^α-Boc-N^δ-Fmoc-γ(R)-methyl-ornithine building block. X-ray crystallog. confirms that the ^δMeOrn turn unit adopts a folded structure in a macrocyclic β-hairpin peptide. CD and NMR spectroscopy allow comparison of the ^δMeOrn turn template to the δ-linked ornithine (^δOrn) turn template that we previously introduced and to the popular D-Pro-Gly turn template. These studies show that the folding of the ^δMeOrn turn template is substantially better than that of ^δOrn and is comparable to D-Pro-Gly. A highly hazardous hydrogenation reaction was performed during the synthesis of N^α-Boc-N^δ-Fmoc-γ(R)-methyl-ornithine.

Receptor-specific peptides labeled with positron emitters play an important role in the clin. imaging of several malignancies by positron emission tomog. (PET). Radiolabeled heterobivalent bispecific peptidic ligands (HBPLs) can target more than one receptor type and by this – besides exhibiting other advantages – increase tumor imaging sensitivity. In the present study, we show the initial in vivo evaluation of the most potent heterobivalent gastrin-releasing peptide receptor (GRPR)- and vasoactive intestinal peptide receptor subtype 1 (VPAC₁R)-bispecific radiotracer and determined its tumor visualization potential via PET/CT imaging. For this purpose, the most potent described HBPL was synthesized together with its partly scrambled heterobivalent monospecific homologs and its monovalent counterparts. The agents were efficiently labeled with ⁶⁸Ga³⁺ and evaluated in an initial PET/CT tumor imaging study in a human prostate carcinoma (PCa) xenograft rat tumor model established for this purpose. None of the three ⁶⁸Ga-HBPLs enabled a clear tumor visualization and a considerably higher involvement in receptor-mediated uptake was found for the GRPR-binding part of the mol. than for the VPAC₁R-binding one. Of the monovalent radiotracers, only [⁶⁸Ga]Ga-NODA-GA-PESIN could efficiently delineate the tumor, confirming the results. Thus, this work sets the direction for future developments in the field of GRPR- and VPAC₁R-bispecific radioligands, which should be based on other VPAC₁R-specific peptides than PACAP-27.

Category: indole-building-block, 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.
