Sequence-specific protection of plasmid DNA from restriction endonuclease hydrolysis by pyrrole-imidazole-cyclopropapyrroloindole conjugates was written by Fujimoto, Kazuhisa;Iida, Hirokazu;Kawakami, Masako;Bando, Toshikazu;Tao, Zhi-Fu;Sugiyama, Hiroshi. And the article was included in Nucleic Acids Research in 2002.Category: imidazoles-derivatives This article mentions the following:

The pyrrole-imidazole (Py-Im) triamide-cyclopropa pyrroloindole (CPI) conjugates ImPyImLDu86 (7) and ImImPyLDu86 (14) were synthesized and their alkylating activities and inhibitory effects on DNA hydrolysis by restriction endonucleases were examined Sequencing gel anal. demonstrated that conjugates 7 and 14 specifically alkylated DNA at 5′-CGCGCG-3′ and 5′-PyGGCCPu-3′, resp. Agarose gel electrophoresis indicated that incubation of a supercoiled plasmid, pSPORT I (4109 bp), with conjugate 7 effectively inhibited its hydrolysis by BssHII (5′-GCGCGC-3′), whereas conjugate 14 had no effect on this hydrolysis. These results suggest that conjugate 7 sequence-specifically inhibits the hydrolysis of DNA by BssHII. Sequence-specific alkylation by the Py-Im triamide-CPI conjugates was further confirmed by inhibition of the Eco52I (5′-CGGCCG-3′) hydrolysis of conjugate 14-treated pQBI PGK (5387 bp). In clear contrast, hydrolysis of pQB1 PGK by DraI (3′-TTTAAA-3′) was not inhibited by 5 μM conjugate 14. That ImImPy did not inhibit the hydrolysis of pQB1 PGK indicates that covalent bond formation is necessary for inhibition. A similar experiment, using linear pQBI PGK, achieved the same extent of protection of the DNA with approx. half the concentration of conjugate 14 as was required to protect supercoiled DNA from hydrolysis. In the experiment, the researchers used many compounds, for example, Ethyl 1-methyl-4-nitro-1H-imidazole-2-carboxylate (cas: 109012-23-9Category: imidazoles-derivatives).

Advancing the Therapeutic Efficacy of Bioactive Molecules by Delivery Vehicle Platforms was written by Tsiailanis, Antonis D.;Tzakos, Andreas G.;Mavromoustakos, Thomas. And the article was included in Current Medicinal Chemistry in 2021.Recommanded Product: 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate This article mentions the following:

Drugs have to overcome numerous barriers to reach their desired therapeutic targets. In several cases, drugs, especially the highly lipophilic mols., suffer from low solubility and bioavailability and therefore their desired targeting is hampered. In addition, undesired metabolic products might be produced or off-targets could be recognized. Along these lines, nanopharmacol. has provided new technol. platforms, to overcome these boundaries. Specifically, numerous vehicle platforms such as cyclodextrins and calixarenes have been widely utilized to host lipophilic drugs such as antagonists of the angiotensin II AT1 receptor (AT₁R), as well as quercetin and silibinin. The encapsulation of these drugs in supramols. or other systems refines their solubility and metabolic stability, increases their selectivity and therefore decreases their ED and improves their therapeutic index. In this mini review we report on the formulations of silibinin and AT₁R antagonist candesartan in a 2-HP-β-cyclodextrin host mol., which displayed enhanced cytotoxicity and increased silibinin′s and candesartan′s stability, resp. Moreover, we describe the encapsulation of quercetin in gold nanoparticles bearing a calixarene supramol. host. Also, the encapsulation of temozolomide in a calixarene nanocapsule has been described.

Organosolv and ionosolv processes for autohydrolyzed poplar fractionation: Lignin recovery and characterization was written by Ovejero-Perez, Antonio;Rigual, Victoria;Dominguez, Juan Carlos;Alonso, M. Virginia;Oliet, Mercedes;Rodriguez, Francisco. And the article was included in International Journal of Biological Macromolecules in 2022.Synthetic Route of C4H7ClN2 This article mentions the following:

Biomass fractionation plays a major role in the search for competitive biorefineries, where the isolation and recovery of the three woody fractions is key. In this sense, we have used autohydrolyzed hemicellulose-free poplar as feedstock to compare two fractionation processes, organosolv and ionosolv, oriented to lignin recovery. The recovered lignins were then characterize by different techniques (NMR, GPC, TGA). Both treatments were tested at different temperatures to analyze temperature influence on lignin recovery and properties. The highest lignin recovery was obtained with the ionosolv process at 135°C, reaching a solid yield of ∼70%. Lignin characterization showed differences between both treatments. Lignins enriched in C-O linkages and G units were recovered with the organosolv process, where increasing temperature led to highly depolymerized lignins. However, lignins with higher C-C linkages and S units contents were obtained with the ionosolv process, producing more thermically stable lignins. In addition, increasing temperature caused lignin repolymn. when employing ionic liquids as solvents. Therefore, this work outlines the most important differences between ionosolv and organosolv processes for biomass fractionation, focusing on lignin recovery and its properties, which is the first step in order to valorize all biomass fractions.

And the article was included in ChemElectroChem in 2021.Reference of 21252-69-7 This article mentions the following:

Ionic liquids are used, for example, as corrosion inhibitors for metals, steel, and metal alloys. The method of preventing corrosion through the whole group of these kinds of compounds, called inhibitors, is to use them as additives to aggressive environments, including aqueous electrolytes. In this article, we present the inhibitive effect of imidazolium ionic liquids with 2,5-dihydroxybenzenesulfonate anion on the corrosion of 316L stainless steel in neutral medium. In addition, we demonstrate that when the ionic liquid is used as an additive to the electrolyte solution (1 M Na₂SO₄) of a sym. carbon/carbon electrochem. capacitor with 316L stainless-steel current collectors, the capacitor lifetime is significantly extended. The ionic-liquid additive inhibits corrosion of the current collector surface and, in effect, prevents activated carbon porous space from being blocked by corrosion products.

The use of smart technologies in the daily lives, from smart phones to auto-dimming windows to touch sensors, has become pervasive. With growing desire for these devices to be conformable and flexible, traditional materials are being replaced to create a class of products known as active organic electronic devices (OEDs). These new devices owe their ability to switch elec. and/or optical function to the intimate interaction between an inherently conducting polymer and electrolyte, typically an ionic liquid Herein, the authors provide the 1st observations that specific ionic liquids can reduce or oxidize conducting polymers upon intimate contact in the absence of any elec. stimuli. The ability to reduce or oxidize the inherently conducting polymer depends on the cation and anion pair within the ionic liquid Extending the utility of this phenomenon is made by fabricating OEDs such as prototype fuel cells, supercapacitors and smart windows.

Phenotypic and transcriptomic response of auxotrophic Mycobacterium avium subsp. paratuberculosis leuD mutant under environmental stress was written by Chen, Jenn-Wei;Scaria, Joy;Chang, Yung-Fu. And the article was included in PLoS One in 2012.Product Details of 26832-08-6 This article mentions the following:

Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of severe gastroenteritis in cattle. To gain a better understanding of MAP virulence, we investigated the role of leuD gene in MAP metabolism and stress response. For this, we have constructed an auxotrophic strain of MAP by deleting the leuD gene using allelic exchange. The wildtype and mutant strains were then compared for metabolic phenotypic changes using Biolog phenotype microarrays. The responses of both strains to physiol. relevant stress conditions were assessed using DNA microarrays. Transcriptomic data was then analyzed in the context of cellular metabolic pathways and gene networks. Our results showed that deletion of leuD gene has a global effect on both MAP phenotypic and transcriptome response. At the metabolic level, the mutant strain lost the ability to utilize most of the carbon, nitrogen, sulfur, phosphorus and nutrient supplements as energy source. At the transcriptome level, more than 100 genes were differentially expressed in each of the stress condition tested. Systems level network anal. revealed that the differentially expressed genes were distributed throughout the gene network, thus explaining the global impact of leuD deletion in metabolic phenotype. Further, we find that leuD deletion impacted metabolic pathways associated with fatty acids. We verified this by exptl. estimating the total fatty acid content of both mutant and wildtype. The mutant strain had 30% less fatty acid content when compared to wildtype, thus supporting the results from transcriptional and computational analyses. Our results therefore reveal the intricate connection between the metabolism and virulence in MAP.
