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.

Molloy, Evelyn M.;Dell, Maria;Haensch, Veit G.;Dunbar, Kyle L.;Feldmann, Romy;Oberheide, Ansgar;Seyfarth, Lydia;Kumpfmueller, Jana;Horch, Therese;Arndt, Hans-Dieter;Hertweck, Christian research published 《 Enzyme-primed native chemical ligation produces autoinducing cyclopeptides in clostridia》, the research content is summarized as follows. 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.

Mladenov, Natalie;Dodder, Nathan G.;Steinberg, Lauren;Richardot, William;Johnson, Jade;Martincigh, Bice S.;Buckley, Chris;Lawrence, Tolulope;Hoh, Eunha research published 《 Persistence and removal of trace organic compounds in centralized and decentralized wastewater treatment systems》, the research content is summarized as follows. 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.

Marquis, Valentin;Smirnova, Ekaterina;Graindorge, Stefanie;Delcros, Pauline;Villette, Claire;Zumsteg, Julie;Heintz, Dimitri;Heitz, Thierry research published 《 Broad-spectrum stress tolerance conferred by suppressing jasmonate signaling attenuation in Arabidopsis JASMONIC ACID OXIDASE mutants》, the research content is summarized as follows. Jasmonate signaling for adaptative or developmental responses generally relies on an increased synthesis of the bioactive hormone jasmonoyl-isoleucine (JA-Ile), triggered by environmental or internal cues. JA-Ile is embedded in a complex metabolic network whose upstream and downstream components strongly contribute to hormone homeostasis and activity. We previously showed that JAO2, an isoform of four Arabidopsis JASMONIC ACID OXIDASES, diverts the precursor jasmonic acid (JA) to its hydroxylated form HO-JA to attenuate JA-Ile formation and signaling. Consequently, JAO2-deficient lines have elevated defenses and display improved tolerance to biotic stress. Here we further explored the organization and regulatory functions of the JAO pathway. Suppression of JAO2 enhances the basal expression of nearly 400 JA-regulated genes in unstimulated leaves, many of which being related to biotic and abiotic stress responses. Consistently, non-targeted metabolomic anal. revealed the constitutive accumulation of several classes of defensive compounds in jao2-1 mutant, including indole glucosinolates and breakdown products. The most differential compounds were agmatine phenolamides, but their genetic suppression did not alleviate the strong resistance of jao2-1 to Botrytis infection. Furthermore, jao2 alleles and a triple jao mutant exhibit elevated survival capacity upon severe drought stress. This latter phenotype occurs without recruiting stronger abscisic acid responses, but relies on enhanced JA-Ile signaling directing a distinct survival pathway with MYB47 transcription factor as a candidate mediator. Our findings reveal the selected spectrum of JA responses controlled by the JAO2 regulatory node and highlight the potential of modulating basal JA turnover to pre-activate mild transcriptional programs for multiple stress resilience.

COA of Formula: C10H8N2, 3-Indoleacetonitrile is a plant growth activator, which promotes callus growth and shoot formation in tobacco callus.
3-Indoleacetonitrile (Indolylacetonitrile) is a light-induced auxin-inhibitory substance that is isolated from light-grown cabbage (Brassica olearea L.) shoots. It inhibits the biofilm formation of both E. coli O157:H7 and P. aeruginosa without affecting its growth.
3-Indoleacetonitrile, also known as 3-(cyanomethyl)indole or IAN, belongs to the class of organic compounds known as 3-alkylindoles. 3-alkylindoles are compounds containing an indole moiety that carries an alkyl chain at the 3-position. 3-Indoleacetonitrile exists as a solid and is considered to be practically insoluble (in water) and relatively neutral. Within the cell, 3-indoleacetonitrile is primarily located in the mitochondria. 3-Indoleacetonitrile participates in a number of enzymatic reactions. In particular, 3-indoleacetonitrile can be biosynthesized from acetonitrile. 3-Indoleacetonitrile is also a parent compound for other transformation products, including but not limited to, cys(ian)-gly, gammaglucys(ian), and L-cys(ian). Outside of the human body, 3-indoleacetonitrile can be found in a number of food items such as cloudberry, japanese persimmon, horned melon, and evergreen huckleberry. This makes 3-indoleacetonitrile a potential biomarker for the consumption of these food products.
Indole-3-acetonitrile is a nitrile that is acetonitrile where one of the methyl hydrogens is substituted by a 1H-indol-3-yl group. It has a role as an auxin, a plant hormone, a plant metabolite and a human xenobiotic metabolite. It is a nitrile and a member of indoles. It derives from an acetonitrile., 771-51-7.
