Selenium deficiency in daily diet is a common problem in many countries, thus searching for new dietary sources of this trace element is an important scientific challenge. Selenium biofortified sprouts from Brassicaceae family are good candidates for new dietary selenium source, as they reveal one of the highest capability to synthesize and accumulate this element. As a part of this extensive search, the influence of novel selenium organic compounds on fortification of kale sprouts biol. activity was investigated. The present study is focused on the evaluation of the influence of these compounds on the synthesis of glucosinolates, isothiocyanates, indoles and phenolic acids in kale sprouts, together with the determination of their impact on antioxidant, anti-inflammatory and cytotoxic activity on gastrointestinal, prostate, and thyroid normal and cancer cells. The present study yields the conclusion that fortification of kale sprouts with selenium organic compounds bearing benzoselenoate scaffold influences the production of isothiocyanates, phenolic acids, and enhances the antioxidant properties of fortified sprouts. Notably, fortification with compounds based on benzoselenoate scaffold display chemoprotective properties in various cancer types (gastric, thyroid, and prostate cancer). The present study can facilitate the design of future agrochems. Compounds bearing benzoselenoate scaffold or selenyl phenylpiperazine motif seem to be particularly promising for these purposes.

Formula: C11H12O5, Sinapinic acid is a chemical compound that is the dihydroxybenzoic acid derivative of sinapic acid. It has been shown to have anti-inflammatory properties in vitro and in vivo. Sinapinic acid inhibits the activity of various enzymes, such as cyclooxygenase (COX), lipoxygenase (LOX), and 5-lipoxygenase-activating protein (FLAP). It also decreases levels of adhesion molecules and downregulates inflammatory response genes. Sinapinic acid has been shown to reduce inflammation by inhibiting the formation of proinflammatory mediators, such as prostaglandin E2 or leukotriene B4, in endothelial cells and mammary epithelial cells.
Sinapic acid is a phenylpropanoid hydroxycinnamic acid with diverse biological activities. Sinapic acid inhibits collagen-induced human platelet aggregation by up to 70% in vitro (IC50 = 1.03 mM). It scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH; ) and 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS) free radicals with IC50 values of 8.3 and 5.4 μg/ml, respectively. Sinapic acid (200 μM) reduces colony formation of SW480 human colon carcinoma cells by 4-fold. It also inhibits colony formation of E. coli, S. enteritidis, and S. aureus on agar (MICs = 2.2, 2, and 1.8 mM, respectively). In vivo, sinapic acid (4 mg/kg, p.o.) increases the time spent in the open arms of the elevated plus maze by approximately 15% in mice, an effect that can be blocked by the GABAA receptor antagonists flumazenil and bicuculline. Sinapic acid is also commonly used as a matrix in protein mass spectrometry.
Sinapic acid analytical standard provided with w/w absolute assay, to be used for quantitative titration.
Sinapic acid is an hydroxycinnamic acid derivative that occurs naturally in Brassicaceae species.
cis-Sinapic acid, also known as cis-sinapate or synapitic acid, belongs to the class of organic compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing an cinnamic acid where the benzene ring is hydroxylated. cis-Sinapic acid is considered to be a practically insoluble (in water) and relatively neutral molecule. Within the cell, cis-sinapic acid is primarily located in the cytoplasm. Outside of the human body, cis-sinapic acid can be found in common pea and pulses. This makes cis-sinapic acid a potential biomarker for the consumption of these food products.
Cis-sinapic acid is a 3-(4-hydroxy-3,5-dimethoxyphenyl)prop-2-enoic acid in which the double bond has cis-configuration. It has been isolated from the shoots of alfalfa. It has a role as a plant metabolite., 530-59-6.

Stapled peptides have the ability to mimic α-helixes involved in protein binding and have proved to be effective pharmacol. agents for disrupting protein-protein interactions. DNA-binding proteins such as transcription factors bind their cognate DNA sequences via an α-helix interacting with the major groove of DNA. We previously developed a stapled peptide based on the bacterial alternative sigma factor RpoN capable of binding the RpoN DNA promoter sequence and inhibiting RpoN-mediated expression in Escherichia coli. We have elucidated a structure-activity relationship for DNA binding by this stapled peptide, improving DNA binding affinity constants in the high nM range. Lead peptides were shown to have low toxicity as determined by their low hemolytic activity at 100 μM and were shown to have anti-virulence activity in a Galleria mellonella model of Pseudomonas aeruginosa infection. These findings support further preclin. development of stapled peptides as antivirulence agents targeting P. aeruginosa.

Paprocki, Maciej P.;Rasmussen, Jakob E.;Soerensen, Kasper K.;Jensen, Knud J. research published 《 Safety-catch linkers for Fmoc solid-phase synthesis of peptide thioesters and hydrazides by amide-to-imide activation》, the research content is summarized as follows. The use of C-terminal peptide thioesters and hydrazides in synthetic protein chem. has inspired the search for optimal solid-phase peptide synthesis (SPPS) strategies for their assembly. However, peptide thioesters are not directly accessible by conventional Fmoc-SPPS (Fmoc = 9-fluorenylmethoxycarbonyl) owing to the nucleophilicity of the secondary amine required for Fmoc removal. Here, we report the mild and effective activation of the pGlu linker and a new safety-catch linker that was used for the convenient synthesis of peptide thioesters and hydrazides via efficient amide-to-imide activation followed by nucleophilic displacement.

Pan, Shulei;Zhu, Qiongqiong;Zhang, Yanghui research published 《 Palladium-Catalyzed Coupling of Biphenyl-2-yl Trifluoromethanesulfonates with Dibromomethane to Access Fluorenes》, the research content is summarized as follows. A facile and efficient method has been developed for the synthesis of fluorenes by Pd-catalyzed C-H alkylation of biphenyl-2-yl trifluoromethanesulfonates. The trifluoromethanesulfonates are more readily available and more environmentally benign than biphenyl iodides, and are advantageous substrates for traceless directing-group-assisted C-H activation. The reaction generates C,C-palladacycles as the key intermediates that form two C(sp²)-C(sp³) bonds through reaction with CH₂Br₂. The reaction tolerates various functional groups, permitting easy access to a range of fluorene derivatives

The nociceptin/orphanin FQ (N/OFQ)/N/OFQ receptor (NOP) system controls different biol. functions including pain and cough reflex. Mixed NOP/opioid receptor agonists elicit similar effects to strong opioids but with reduced side effects. In this work, 31 peptides with the general sequence [Tyr/Dmt¹,Xaa⁵]N/OFQ(1-13)-NH₂ were synthesized and pharmacol. characterized for their action at human recombinant NOP/opioid receptors. The best results in terms of NOP vs. mu opioid receptor potency were obtained by substituting both Tyr¹ and Thr⁵ at the N-terminal portion of N/OFQ(1-13)-NH₂ with the noncanonical amino acid Dmt. [Dmt^1,5]N/OFQ(1-13)-NH₂ has been identified as the most potent dual NOP/mu receptor peptide agonist so far described. Exptl. data have been complemented by in silico studies to shed light on the mol. mechanisms by which the peptide binds the active form of the mu receptor. Finally, the compound exerted antitussive effects in an in vivo model of cough.

Ozkose, Umut Ugur;Gulyuz, Sevgi;Parlak Khalily, Melek;Ozcubukcu, Salih;Bozkir, Asuman;Tasdelen, Mehmet Atilla;Alpturk, Onur;Yilmaz, Ozgur research published 《 The synthesis of peptide-conjugated poly(2-ethyl-2-oxazoline)-b-poly(L-lactide) (PEtOx-b-PLA) polymeric systems through the combination of controlled polymerization techniques and click reactions》, the research content is summarized as follows. To optimize the therapeutic effect of pharmaceutical agents, drug delivery systems tailored from FDA-approved polymers like poly(L-lactide) (PLA) is an effective strategy. Because of their hydrophobic character, these systems greatly suffer from reduced circulation time thus, amphiphilic block copolymers became favorable to overcome this limitation. Of them, poly(oxazoline)-b-poly(L-lactide) are of choice as poly(oxazoline) (PEtOx) is compatible, biodegradable, while exhibiting min. cytotoxicity. To tailor selective drug targeting drug delivery systems, whereby their selectivity for tumor tissues is maximized, these polymers should be decorated with so-called tumor-homing agents, such as antibodies, peptides and so forth. To this respect, we designed a new block copolymer, allyl-poly(2-ethyl-2-oxazoline)-b-poly(L-lactide) allyl-(PEtOx-b-PLA) and its subsequent conjugation to tumor-homing peptides, peptide-18, and peptide-563 at the terminal position. In this manuscript, we report our synthetic route to obtain this building block and its conjugation to tumor-homing agents.

A concise and versatile synthetic strategy for the total synthesis of arylnaphthalene lignans and aza-analogs was developed. The main objective was to develop synthetic tactics for the creation of the lactone and lactam unit that would give access to an array of synthetic, natural, and/or bioactive compounds through rather simple chem. manipulation. The flexibility and potentiality of these new processes were further illustrated by the total synthesis of retrojusticidin B (13b), justicidin C (14b), and methoxy-vitedoamine A (22a). In this study, a series of novel aryl-naphthalene lignans and aza-analogs were synthesized, and the cytotoxic activities of all compounds on cancer cell growth were evaluated. The target compounds were structurally characterized by 1H NMR (NMR), 13C NMR, IR, high-resolution mass spectrometry, and X-ray crystallog. The IC50 values of these compounds on five tumor cell lines (A549, HS683, MCF-7, SK-MEL-28, and B16-F1) were obtained by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) colorimetric assay. Five of the compounds exhibited excellent activity compared to 5-fluorouracil and etoposide against the five cell lines tested, with IC50 values ranging from 1 to 10μM.

Jr research published 《 Extended Hildebrand solubility approach applied to sulphadiazine in aqueous binary mixtures of Carbitol and N-methyl-2-pyrrolidone at 313.15 K》, the research content is summarized as follows. Extended Hildebrand Solubility Approach (EHSA) was applied in this research to analyze the equilibrium solubility of sulphadiazine in some {N-methyl-2-pyrrolidone (1) + water (2)} and {Carbitol (1) + water (2)} mixtures at 313.15 K. Reported exptl. solubilities and melting properties of this drug were used for EHSA calculations Good predictive character of EHSA (with mean deviations lower than 1.7%) was found by using regular polynomials in order five by correlating the interaction parameter (W) and the Hildebrand solubility parameter of solvent mixtures free of drug (δ₁₊₂). However, the predictive character of EHSA was almost the same as obtained when logarithmic drug solubilities (log x₃) were correlated with δ₁₊₂ by using a fifth-degree regular polynomial.
