On September 30, 2008, Thevenot, Paul; Cho, Jai; Wavhal, Dattatray; Timmons, Richard B.; Tang, Liping published an article.Synthetic Route of 929-37-3 The title of the article was Surface chemistry influences cancer killing effect of TiO2 nanoparticles. And the article contained the following:

Photocatalyzed titanium dioxide (TiO2) nanoparticles were shown to eradicate cancer cells. However, the required in situ introduction of UV light limits the use of such a therapy in humans. In the present study the nonphotocatalytic anticancer effect of surface-functionalized TiO2 was examined Nanoparticles bearing -OH, -NH2, or -COOH surface groups were tested for their effect on in vitro survival of several cancer and control cell lines. The cells tested included B16F10 melanoma, Lewis lung carcinoma, JHU prostate cancer cells, and 3T3 fibroblasts. Cell viability was observed to depend on particle concentrations, cell types, and surface chem. Specifically, -NH2 and -OH groups showed significantly higher toxicity than -COOH. Microscopic and spectrophotometric studies revealed nanoparticle-mediated cell membrane disruption leading to cell death. The results suggest that functionalized TiO2, and presumably other nanoparticles, can be surface-engineered for targeted cancer therapy. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Synthetic Route of 929-37-3

Andre, Mathieu; Tarrit, Sebastien; Couret, Marie-Joelle; Galmier, Marie-Josephe; Debiton, Eric; Chezal, Jean-Michel; Mounetou, Emmanuelle published an article in 2013, the title of the article was Spacer optimization of new conjugates for a melanoma-selective delivery approach.Application of 929-37-3 And the article contains the following content:

In the search for more selective anticancer drugs, we designed and synthesized seven conjugates varying the structure of the linker connecting the 5-iodo-2′-deoxyuridine (IUdR) to the ICF 01012 melanoma-carrier for potential intratumoral specific drug release. Chem. and in vitro metabolic stability evaluations showed that, except for the ester conjugate (1), the ketal (2b), acetal (2a), carbonate (4) and carbamate (3) conjugates were compatible with our approach. The acetal (2a) and its PEGylated derivative (2c) were of particular interest for further in vivo development owing to their resp. pH-dependent stability and limited metabolic degradation in order to exploit the acidic subcellular environment of malignant melanocytes to trigger the release of therapeutics upon internalization in cells. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Application of 929-37-3

On March 31, 2021, Zhou, Fei; Last, Robert L.; Pichersky, Eran published an article.Application of 91-16-7 The title of the article was Degradation of salicylic acid to catechol in Solanaceae by SA 1-hydroxylase. And the article contained the following:

The hormone salicylic acid (SA) plays crucial roles in plant defense, stress responses, and in the regulation of plant growth and development. Whereas the biosynthetic pathways and biol. functions of SA have been extensively studied, SA catabolism is less well understood. In this study, we report the identification and functional characterization of an FAD/NADH-dependent SA 1-hydroxylase from tomato (Solanum lycopersicum; SlSA1H), which catalyzes the oxidative decarboxylation of SA to catechol. Transcript levels of SlSA1H were highest in stems and its expression was correlated with the formation of the methylated catechol derivatives guaiacol and veratrole. Consistent with a role in SA catabolism, SlSA1H RNAi plants accumulated lower amounts of guaiacol and failed to produce any veratrole. Two O-methyltransferases involved in the conversion of catechol to guaiacol and guaiacol to veratrole were also functionally characterized. Subcellular localization analyses revealed the cytosolic localization of this degradation pathway. Phylogenetic anal. and functional characterization of SA1H homologs from other species indicated that this type of FAD/NADH-dependent SA 1-hydroxylases evolved recently within the Solanaceae family. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Application of 91-16-7

On October 15, 2009, Chu, Li-Qiang; Knoll, Wolfgang; Foerch, Renate published an article.Application In Synthesis of 2-(2-(Vinyloxy)ethoxy)ethanol The title of the article was Plasma polymerized non-fouling thin films for DNA immobilization. And the article contained the following:

Development of DNA sensors has been an issue of great interest, owing to their potential applications in different fields, such as the diagnosis of infectious diseases, food quality control, or for environmental monitoring. Most DNA sensors involved the immobilization of single-stranded oligonucleotides, so-called DNA probes, onto the sensor surfaces. Here we report on a new approach for DNA probe immobilization using the streptavidin-biotin assembly coupled with a non-fouling thin film. Pulsed plasma polymerization of di(ethylene glycol) monovinyl ether (ppEO2) will result in non-fouling thin films, which are employed to immobilize streptavidin. By careful control of the thickness and the chem. of ppEO2 films, the embedded streptavidin are able to bind the biotinylated oligonucleotides. The resulting DNA sensors show good resistance towards adsorption of both BSA and fibrinogen, and are employed to discriminate different DNA sequences from protein-containing sample solutions, as seen by surface plasmon enhanced fluorescence spectroscopy (SPFS). This result suggests that the present sensor is very promising for the detection of a DNA sequence from a complex solution The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Application In Synthesis of 2-(2-(Vinyloxy)ethoxy)ethanol

Ruzo, Luis O.; Unai, Tadaaki; Casida, John E. published an article in 1978, the title of the article was Decamethrin metabolism in rats.Electric Literature of 66855-92-3 And the article contains the following content:

On oral administration to male rats, the pyrethroid insecticide decamethrin (I) [52918-63-5] and various metabolites derived from its acid and alc. fragments were almost completely eliminated from the body within 2-4 days. Metabolites of the cyano substituent were eliminated more slowly, especially from the skin and stomach, due in the latter case to temporary retention of thiocyanate which was formed from released cyanide. The excreted metabolites included: esters monohydroxylated at the 2′, 4′, and 5 positions of the alc. moiety; 2,2-dimethyl-3-(2,2-dibromovinyl)cyclopropanecarboxylic acid [59952-39-5] and its glucuronide [66855-97-8] and glycine conjugate [66855-98-9] and a hydroxylated derivative [66855-99-0] of this acid, with the hydroxymethyl group trans to the carboxyl, and its glucuronide [66856-00-6]; 3-phenoxybenzoic acid [3739-38-6] and its glucuronide [57991-35-2] and glycine conjugate [57991-36-3], 3-(4-hydroxyphenoxy)benzoic acid [35065-12-4] and its glucuronide [66856-01-7] and sulfate conjugate [58218-91-0], and 3-(2-hydroxyphenoxy)benzoic acid sulfate [61183-26-4]; thiocyanate [302-04-5] and 2-iminothiazolidine-4-carboxylic acid [2150-55-2]. Trans-Decamethrin [64363-96-8] was also rapidly metabolized in rats.

On July 15, 2005, Moise, Tamar; Rudich, Yinon; Rousse, Davy; George, Christian published an article.Category: ethers-buliding-blocks The title of the article was Multiphase Decomposition of Novel Oxygenated Organics in Aqueous and Organic Media. And the article contained the following:

Prior to the massive use of new oxygenated solvents, data on their multiphase reactivity must be obtained to assess their environmental fate and impact on water and air quality. For this, the kinetics and mechanisms of the photochem. and photocatalytic degradation of selected oxygenated solvents by common tropospheric oxidants (such as OH and ozone) must be characterized. The authors studied the oxidation kinetics of new oxygenated solvents as pure organic liquids and in an aqueous medium by ozone and by the OH radical, resp. The studied chems. are all unsaturated compounds, having none, one, or two ether groups. The OH reaction proceeds at the diffusion limit by addition to the double bond. The reactive uptake coefficients associated with the reaction initiated by ozone are of the order of 10-3. The reactions of compounds with two double bonds are very fast and probably occur at the surface. This kinetic information demonstrates that organic solvents in an organic medium or in an aqueous droplet will be oxidized rapidly by these oxidation reactions. These reactions, however, are not significant sinks for ozone and OH radicals.

On December 31, 2020, Lopez-Arencibia, Atteneri; Bethencourt-Estrella, Carlos J.; Freijo, Monica B.; Reyes-Batlle, Maria; Sifaoui, Ines; Nicolas-Hernandez, Desiree San; McNaughton-Smith, Grant; Lorenzo-Morales, Jacob; Abad-Grillo, Teresa; Pinero, Jose E. published an article.Product Details of 93-04-9 The title of the article was New phenalenone analogues with improved activity against Leishmania species. And the article contained the following:

The in vitro activity against Leishmania spp. of five novel designed compounds, phenalenone derivatives, is described in this study. Previous works have shown that some phenalenones present leishmanicidal activity, some of which could induce programmed cell death events in L. amazonensis parasites. In this research, we focused on the determination of the programmed cell death evidence by detecting the characteristic features of the apoptosis-like process, such as phosphatidylserine exposure and mitochondrial membrane potential, among others. The results showed that the new derivatives have comparable or better activity and selectivity than the commonly prescribed anti-leishmanial drug. This result was obtained by inducing stronger mitochondrial depolarization or more intense phosphatidylserine exposure than miltefosine, highlighting compound 8 with moreover 9-times better selectivity index. In addition, the new five mols. activated the apoptosis-like process in the parasite. All the signals observed were indicative of the death process that the parasites were undergoing. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Product Details of 93-04-9
