Chem. synthesized, small peptides that bind with high affinity and specificity to CD8-expressing (CD8+) tumor-infiltrating T cells, yet retain the desirable characteristics of small mols., hold valuable potential for diagnostic mol. imaging of immune response. Here, we report the development of ¹⁸F-labeled peptides targeting human CD8α with nanomolar affinity via the strain-promoted sydnone-alkyne cycloaddition with 4-[¹⁸F]fluorophenyl sydnone. The ¹⁸F-sydnone is produced in one step, in high radiochem. yield, and the peptide labeling proceeds rapidly. A hydrophilic chem. linker results in a tracer with favorable pharmacokinetic properties and improved image contrast, as demonstrated by in vivo PET imaging studies.

Nadeem, Hera;Malan, Pieter;Khan, Amir;Asif, Mohd;Ahmad Siddiqui, Mansoor;Tuhafeni Angombe, Simon;Ahmad, Faheem research published 《 New insights on the utilization of ultrasonicated mustard seed cake: chemical composition and antagonistic potential for root-knot nematode, Meloidogyne javanica》, the research content is summarized as follows. This study focused, for the first time, on the effect of ultrasonic features on the extraction efficiency of secondary metabolites in mustard seed cake (MSC). The nematostatic potential of sonicated seed cake was examined against the second-stage juveniles (J2s) of root-knot nematode, Meloidogyne javanica. The results show that a 35 ppm (ppm) concentration of a sonicated extract (SE) sample of MSC caused 65% J2s mortality at 18 h exposure period in vitro. It also significantly suppressed the root-knot index (RKI=0.94) in tomato roots. The lethal concentration values for SE were 51.76, 29.79, and 13.34 ppm, resp., at 6, 12, and 18 h of the exposure period, and the lethal concentration values for the non-sonicated extract (NSE) sample were 116.95, 76.38, and 55.59 ppm, resp., at similar exposure time. Sinapine and gluconapin were identified as the major compounds in ultrasonic-assisted MSC. Because of the high extraction efficiency of metabolites in the SE, all treatments of SE were shown to be antagonistic to J2s. Thus, this study of ultrasonication activity-based profiling of MSC may help generate target-based compounds at a scale relevant to the control of disease caused by nematodes in economic crops.

Nadal-Bufi, Ferran;Mason, Jody M.;Chan, Lai Yue;Craik, David J.;Kaas, Quentin;Troeira Henriques, Sonia research published 《 Designed β-Hairpins Inhibit LDH5 Oligomerization and Enzymatic Activity》, the research content is summarized as follows. Lactate dehydrogenase 5 (LDH5) is overexpressed in metastatic tumors and is an attractive target for anticancer therapy. Small-mol. drugs have been developed to target the substrate/cofactor sites of LDH5, but none has reached the clinic to date, and alternative strategies remain almost unexplored. Combining rational and computer-based approaches, we identified peptidic sequences with high affinity toward a β-sheet region that is involved in protein-protein interactions (PPIs) required for the activity of LDH5. To improve stability and potency, these sequences were grafted into a cyclic cell-penetrating β-hairpin peptide scaffold. The lead grafted peptide, cGmC9, inhibited LDH5 activity in vitro in low micromolar range and more efficiently than the small-mol. inhibitor GNE-140. CGmC9 inhibits LDH5 by targeting an interface unlikely to be inhibited by small-mol. drugs. This lead will guide the development of new LDH5 inhibitors and challenges the landscape of drug discovery programs exclusively dedicated to small mols.

Mukherjee, Nabanita;Roy, Rajsekhar;Ghosh, Satyajit;Ghosh, Surajit research published 《 Self-Assembled Antimitotic Peptide Vesicle Designed from α,β-Tubulin Heterodimer Interface for Anticancer Drug Delivery》, the research content is summarized as follows. Peptide based anticancer mol. act simultaneously as potent anticancer therapeutic as well as unique drug delivery vehicle for the targeted delivery of often cytotoxic abysmally bioavailable anticancer drugs to their designated organelle. The atypical self-assembling propensity of peptides gives rise to distinct nanostructures capable of encapsulating various drug payload. Among three different types of cytoskeletons presents in eukaryotes, microtubule plays a quintessential role during the course of cell cycle. Microtubule-targeting agents continues to be the most unwavering classes of antineoplastic drugs for the treatment of cancer. Any intervention to the dynamic tubulin assembly-disassembly process will definitely lead to complete perturbation of total cell division process. Several tubulin targeted antimitotic drugs had been designed as well as discovered to disrupt this dynamic nature of tubulin monomers either by inducing extensive polymerization or depolymerization, thereby facilitating overall cell cycle arrest. However, in cancer cells, aberrant mTOR activity causes growing resistance against numerous tubulin targeted drugs inducing metastasization, and simultaneous invasion to new healthy tissues. In recent years, numerous tubulin targeted drugs have been found to have high activity in a combination with mTOR inhibitors like tacrolimus, everolimus (RAD001), etc. but restrained bioavailability, non-specificity and quick excretion are the major impediments for the successful implementation. Combining the immense importance of protein-peptide interaction for the development of future anticancer therapeutics as well as self-assembling propensity of peptides we have taken a unique approach to craft a microtubule targeting antimitotic peptide designed from α,β-tubulin heterodimer interface, which promotes both in vitro and in vivo tubulin depolymerization, exhibiting middling toxicity towards MCF7 cells, causing cell cycle arrest. Further AFM images of this β-sheet forming peptide reveals that this peptide upon self-assembly give rise to spectacular vesicle structural characteristics which can be used as a vehicle for a combination delivery of Docetaxel and RAD001 in order to enhance their individual therapeutic potency. Encapsulation of propidium iodide and concomitant release studies suggest that Pep-4 vesicles could be a potential candidate for tubulin targeted sustained release of therapeutics. Here, our designed peptide vesicles are found to capable for the delivery of tubulin targeting drug Docetaxel along with an well-known mTOR inhibiting drug RAD001 successfully to breast cancer cell line in order to achieve a robust symbiotic effect.

Mondal, Pritam;Rajapakse, Shanuk;Wijeratne, Gayan B. research published 《 Following Nature’s Footprint: Mimicking the High-Valent Heme-Oxo Mediated Indole Monooxygenation Reaction Landscape of Heme Enzymes》, the research content is summarized as follows. Pathways for direct conversion of indoles to oxindoles have accumulated considerable interest in recent years due to their significance in the clear comprehension of various pathogenic processes in humans and the multipotent therapeutic value of oxindole pharmacophores. Heme enzymes are predominantly responsible for this conversion in biol. and are thought to proceed with a compound-I active oxidant. These heme-enzyme-mediated indole monooxygenation pathways are rapidly emerging therapeutic targets; however, a clear mechanistic understanding is still lacking. Addnl., such knowledge holds promise in the rational design of highly specific indole monooxygenation synthetic protocols that are also cost-effective and environmentally benign. We herein report the first examples of synthetic compound-I and activated compound-II species that can effectively monooxygenate a diverse array of indoles with varied electronic and steric properties to exclusively produce the corresponding 2-oxindole products in good to excellent yields. Rigorous kinetic, thermodn., and mechanistic interrogations clearly illustrate an initial rate-limiting epoxidation step that takes place between the heme oxidant and indole substrate, and the resulting indole epoxide intermediate undergoes rearrangement driven by a 2,3-hydride shift on indole ring to ultimately produce 2-oxindole. The complete elucidation of the indole monooxygenation mechanism of these synthetic heme models will help reveal crucial insights into analogous biol. systems, directly reinforcing drug design attempts targeting those heme enzymes. Moreover, these bioinspired model compounds are promising candidates for the future development of better synthetic protocols for the selective, efficient, and sustainable generation of 2-oxindole motifs, which are already known for a plethora of pharmacol. benefits.

Clostridia coordinate many important processes such as toxin production, infection, and survival by d.-dependent communication (quorum sensing) using autoinducing peptides (AIPs). Although clostridial AIPs have been proposed to be (thio)lactone-containing peptides, their true structures remain elusive. Here, we report the genome-guided discovery of an AIP that controls endospore formation in Ruminiclostridium cellulolyticum. Through a combination of chem. synthesis and chem. complementation assays with a mutant strain, we reveal that the genuine chem. mediator is a homodetic cyclopeptide (cAIP). Kinetic analyses indicate that the mature cAIP is produced via a cryptic thiolactone intermediate that undergoes a rapid S→N acyl shift, in a manner similar to intramol. native chem. ligation (NCL). Finally, by implementing a chem. probe in a targeted screen, we show that this novel enzyme-primed, intramol. NCL is a widespread feature of clostridial AIP biosynthesis.

Modrzycka, Sylwia;Kolt, Sonia;Polderdijk, Stephanie G. I.;Adams, Ty E.;Potoczek, Stanislaw;Huntington, James A.;Kasperkiewicz, Paulina;Drag, Marcin research published 《 Parallel imaging of coagulation pathway proteases activated protein C, thrombin, and factor Xa in human plasma》, the research content is summarized as follows. Activated protein C (APC), thrombin, and factor (f) Xa are vitamin K-dependent serine proteases that are key factors in blood coagulation. Moreover, they play important roles in inflammation, apoptosis, fibrosis, angiogenesis, and viral infections. Abnormal activity of these coagulation factors has been related to multiple conditions, such as bleeding and thrombosis, Alzheimer′s disease, sepsis, multiple sclerosis, and COVID-19. The individual activities of APC, thrombin, and fXa in coagulation and in various diseases are difficult to establish since these proteases are related and have similar substrate preferences. Therefore, the development of selective chem. tools that enable imaging and discrimination between coagulation factors in biol. samples may provide better insight into their roles in various conditions and potentially aid in the establishment of novel diagnostic tests. In our study, we used a large collection of unnatural amino acids, and this enabled us to extensively explore the binding pockets of the enzymes′ active sites. Based on the specificity profiles obtained, we designed highly selective substrates, inhibitors, and fluorescent activity-based probes (ABPs) that were used for fast, direct, and simultaneous detection of APC, thrombin, and fXa in human plasma.

The persistence of trace organic chems. in treated effluent derived from both centralized wastewater treatment plants (WWTPs) and decentralized wastewater treatment systems (DEWATS) is of concern due to their potential impacts on human and ecosystem health. Here, we utilize non-targeted anal. (NTA) with comprehensive two-dimensional gas chromatog. coupled with time of flight mass spectrometry (GC x GC/TOF-MS) to conduct an evaluation of the common persistent and removed compounds found in two centralized WWTPs in the USA and South Africa and one DEWATS in South Africa. Overall, removal efficiencies of chems. were similar between the treatment plants when they were compared according to the number of chem. features detected in the influents and effluents of each treatment plant. However, the DEWATS treatment train, which has longer solids retention and hydraulic residence times than both of the centralized WWTPs and utilizes primarily anaerobic treatment processes, was able to remove 13 addnl. compounds and showed a greater decrease in normalized peak areas compared to the centralized WWTPs. Of the 111 common compounds tentatively identified in all three influents, 11 compounds were persistent in all replicates, including 5 compounds not previously reported in effluents of WWTPs or water reuse systems. There were no significant differences among the physico-chem. properties of persistent and removed compounds, but significant differences were observed among some of the mol. descriptors. These results have important implications for the treatment of trace organic chems. in centralized and decentralized WWTPs and the monitoring of new compounds in WWTP effluent.

Copper-containing metalloenzymes constitute a major class of proteins that catalyze a myriad of reactions in nature. Inspired by the structural and functional characteristics of this unique class of metalloenzymes, we report the conception, design, characterization, and functional studies of a de novo artificial copper peptide (ArCuP) within a trimeric self-assembled polypeptide scaffold that activates and reduces peroxide. Using a first-principles approach, the ArCuP was designed to coordinate one Cu via three His residues introduced at an a site of the peptide scaffold. X-ray crystallog., UV-vis, and ESR data demonstrate that Cu binds via the N_ε atoms of His forming a T2Cu environment. When reacted with hydrogen peroxide, the putative copper-hydroperoxo species is formed where a reductive priming step accelerates the rate of its formation and reduction Mass spectrometry was used to identify specific residues undergoing oxidative modification, which showed His oxidation only in the reduced state. The redox behavior of the ArCuP was elucidated by protein film voltammetry. Detailed characterization of the electrocatalytic behavior of the ArCuP led us to determine the catalytic parameters (K_M and k_cat), which established the peroxidase activity of the ArCuP. Combined spectroscopic and electrochem. data showed a pH dependence on the reactivity, which was optimum at pH 7.5.

HPLC of Formula: 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.

Mishra, Abhaya Kumar;Tessier, Romain;Hari, Durga Prasad;Waser, Jerome research published 《 Amphiphilic iodine(III) reagents for the lipophilization of peptides in water》, the research content is summarized as follows. We report the functionalization of cysteine residues with lipophilic alkynes bearing a silyl group or an alkyl chain using amphiphilic ethynylbenziodoxolone reagents (EBXs). The reactions were carried out in buffer (pH 6 to 9), without organic co-solvent or removal of oxygen, either at 37°C or room temperature The transformation led to a significant increase of peptide lipophilicity and worked for aromatic thiols, homocysteine, cysteine, and peptides containing 4 to 18 amino acids. His₆-Cys-Ubiquitin was also alkynylated under physiol. conditions. Under acidic conditions, the thioalkynes were converted into thioesters, which could be cleaved in the presence of hydroxylamine.
