Two cationic ruthenium(II) 1,4,7-trithiacyclononane ([9]aneS₃) complexes of curcumin (curcH) and bisdemethoxycurcumin (bdcurcH), namely [Ru(curc)(DMSO-S)([9]aneS₃)]Cl (1) and [Ru(bdcurc)(DMSO-S)([9]aneS₃)]Cl (2) were prepared from the [RuCl₂(DMSO-S)([9]-aneS₃)] precursor and structurally characterized, both in solution and in the solid state by x-ray crystallog. The corresponding PTA complexes [Ru(curc)(PTA)([9]aneS₃)]Cl (3) and [Ru(bdcurc)(PTA)([9]aneS₃)]Cl (4) were also synthesized and characterized (PTA = 1,3,5-triaza-7-phosphaadamantane). Bioinorganic studies relying on mass spectrometry were performed on complexes 1–4 to assess their interactions with the model protein lysozyme. Overall, a rather limited reactivity with lysozyme was highlighted accompanied by a modest cytotoxic potency against three representative cancer cell lines. The moderate pharmacol. activity is likely connected to the relatively high stability of these complexes. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Computed Properties of C19H16O4).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Computed Properties of C19H16O4

Evaluation of plant extracts as an efficient source of additives for active food packaging was written by Vieira, Dalila M.;Pereira, Carla;Calhelha, Ricardo C.;Barros, Lillian;Petrovic, Jovana;Sokovic, Marina;Barreiro, Maria Filomena;Ferreira, Isabel C. F. R.;Castro, Maria Cidalia R.;Rodrigues, Pedro V.;Machado, Ana Vera. And the article was included in Food Frontiers in 2022.Formula: C19H16O4 The following contents are mentioned in the article:

Natural extracts have been used in several traditional medicine applications and culinary purposes. Their biol. properties (antioxidant and antimicrobial) are due to the presence of several active aromatic compounds Herein, different natural extracts were evaluated, namely structural and thermal characterization and biol. activity, in its natural form and incorporated into a polymeric matrix, to assess their effective potential as additives for active food packaging. While rosemary presented the highest thermal stability with a degradation starting at 327°C, lemon balm extract was the less stable (180°C). Regarding the thiobarbituric acid assay, all extracts presented antioxidant activity, in oxidative hemolysis inhibition; anise, cinnamon, and clove extract did not present any action. Overall, the results demonstrated that leaves (rosemary and green tea) and the rhizome (curcumin) are the plant parts with the best performance. Therefore, extracts from aromatic plants are promising natural additives that can be incorporated into polymeric matrixes to produce active food packaging film, increasing products shelf-life. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Formula: C19H16O4).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols.

Correlation and Prediction of Environmental Properties of Alcohol Ethoxylate Surfactants Using the UNIFAC Method was written by Cheng, Hongyuan;Kontogeorgis, Georgios M.;Stenby, Erling H.. And the article was included in Industrial & Engineering Chemistry Research in 2005.Recommanded Product: 112-59-4 The following contents are mentioned in the article:

Environmental properties of one type of nonionic surfactants, the alc. ethoxylates (polyoxyethylene alcs.), are predicted using the UNIFAC (universal quasi-chem. functional group activity coefficient) method. Various properties are considered; the octanol-water partition coefficient (K_ow), the bioconcentration factor (BCF), and the toxicity. K_ow values of alc. ethoxylates are difficult to measure. Existing methods such as those in com. software like ACD,¹³ ClogP,¹⁴ and KowWin¹⁵ have not been applied to surfactants, and they fail for heavy alc. ethoxylates (alkyl carbon numbers above 12). Thus, the K_ow values are predicted here via UNIFAC and compared to the few available exptl. data. Based on the predicted K_ow values, a correlation between K_ow and hydrophilic-lipophilic balance (HLB) is established because HLB is a widely used parameter in surfactant applications. Finally, BCF and toxicity of alc. ethoxylates are correlated with their K_ow. The proposed approach can be extended to other families of nonionic surfactants. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Recommanded Product: 112-59-4).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Recommanded Product: 112-59-4

Properties and applications of microemulsions was written by Klier, John;Tucker, Christopher J.;Kalantar, Thomas H.;Green, D. P.. And the article was included in Advanced Materials (Weinheim, Germany) in 2000.Product Details of 112-59-4 The following contents are mentioned in the article:

Microemulsions are thermodynamically stable, fluid, optically clear dispersions of two immiscible liquids Recent interest in microemulsion systems has resulted from their utility in a broad range of applications including enhanced oil recovery, consumer and pharmaceutical formulations, nanoparticle synthesis, and chem. reaction media. However, the high levels typically required to ensure complete microemulsification and formulation stability often result in unacceptably high residue, contaminant levels, and formulation cost. One way to reduce surfactant requirements in microemulsion systems is through the use of efficient surfactants and interfacially active cosurfactants. The authors have explored and developed microemulsion systems based on efficient anionic surfactants and glycol ether cosurfactants that are stable to temperature and compositional changes and yet employ low levels of non-volatile surfactants. These microemulsion systems are finding utility in a range of applications, including consumer and industrial cleaning formulations, chem. reaction media, polymerization, and active ingredient delivery. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Product Details of 112-59-4).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Product Details of 112-59-4

Ceria supported gold-platinum catalysts for the selective oxidation of alkyl ethoxylates was written by Heidkamp, Katharina;Aytemir, Memet;Vorlop, Klaus-Dieter;Pruesse, Ulf. And the article was included in Catalysis Science & Technology in 2013.Formula: C10H22O3 The following contents are mentioned in the article:

This work covers the development of a ceria based AuPt catalyst for the selective aerobic oxidation of alkyl ethoxylates to their corresponding carboxylic acids. By optimizing metal loading and the Au to Pt ratio the activity of the catalyst could be increased significantly, while maintaining total selectivity. Although the choice of ceria as a support helped to suppress intermediate metal leaching, the catalyst still showed poor long-term stability in repeated batches. The cause for deactivation could finally be identified by TPR studies as over-oxidation These suspicions were confirmed by a long-term stability study in continuous-mode. It proved to be possible to deactivate the catalyst on purpose by employing unfavorable oxidising reaction conditions, i.e. low substrate concentrations and excess oxygen. By avoiding such unfavorable conditions either in continuous-flow mode or in repeated batches, the long-term stability of the catalyst increased tremendously. A substrate screening of various ethoxylates showed that the catalyst was very well-suited to selectively oxidize a wide range of alkyl ethoxylates. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Formula: C10H22O3).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters are also usually derived from carboxylic acids.

Polyethyleneimine-Modified Polymer as an Efficient Palladium Scavenger and Effective Catalyst Support for a Functional Heterogeneous Palladium Catalyst was written by Yamada, Tsuyoshi;Kobayashi, Yutaka;Ito, Naoya;Ichikawa, Tomohiro;Park, Kwihwan;Kunishima, Kouki;Ueda, Shun;Mizuno, Masahiro;Adachi, Tadashi;Sawama, Yoshinari;Monguchi, Yasunari;Sajiki, Hironao. And the article was included in ACS Omega in 2019.Category: ethers-buliding-blocks The following contents are mentioned in the article:

The polyethyleneimine-modified polymers, polystyrene-divinylbenzene-based (TAs) and polymethacrylate-based polymers (TAm), were used as palladium scavengers to eliminate residual palladium species after palladium on carbon-catalyzed Sonogashira-type coupling reaction. Since both TAs and TAm indicated relatively favorable elimination abilities toward residual palladium species in the reaction mixture, the affinities of TAs and TAm for palladium species were used as supports for palladium catalysts. The TAm-supported palladium catalyst (Pd/TAm) indicated better catalyst properties for the chemoselective hydrogenation compared to those of the corresponding TAs-supported palladium catalyst (Pd/TAs). Aromatic benzyl ethers; aromatic and aliphatic N-Cbzs; and aromatic carbonyl groups were smoothly hydrogenated in the presence of 1-5 mol% of Pd/TAm in MeOH or 2-PrOH. In contrast, the hydrogenation of aromatic ketones was selectively suppressed in morpholine which act as appropriate catalyst poison and solvent. Furthermore, Pd/TAm-catalyzed chemoselective hydrogenation was applicable to continuous-flow reaction. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Category: ethers-buliding-blocks).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones.

Phenolic profile of oils obtained from “horchata” by-products assisted by supercritical-CO₂ and its relationship with antioxidant and lipid oxidation parameters: Triple TOF-LC-MS-MS characterization was written by Rosello-Soto, Elena;Barba, Francisco J.;Lorenzo, Jose M.;Munekata, Paulo E. S.;Gomez, Belen;Molto, Juan Carlos. And the article was included in Food Chemistry in 2019.Formula: C9H12O3 The following contents are mentioned in the article:

In this study, the effect of different supercritical CO₂ (SC-CO₂) pressures (10-40 MPa) on phenolic compounds extraction in oils obtained from “horchata” byproducts was evaluated, and the results were compared to those obtained after conventional oil extraction (CE). Moreover, the relationship between the individual phenolic compounds and the total antioxidant capacity as well as oil oxidative quality parameters was compared. The phenolic profile and contents were largely influenced by extracting conditions. The main phenolic compound obtained by SC-CO₂ was the isohydroxymatairesinol, particularly at 30 and 40 MPa, while 3-vinylphenol was the predominant compound in oils extracted by CE procedure. Increasing SC-CO₂ extraction pressures enhanced the extraction of phenolic compounds, along with improving the antioxidant capacity and oxidative quality of extracted oil. The principal component anal. indicated that the main phenolic compounds associated with TEAC values were those extracted by SC-CO₂, which were inversely correlated to oxidative indexes. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Formula: C9H12O3).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
