Twenty four tetrahydropyran esters were synthesized and tested as attractants toward Blattella germanica and Supella longipalpa in the laboratory by using the choice-chamber method. In general, carboxylates were superior to propionates and acetates. Among the 2-, 3-, or 4-substituted esters, substitution at the 4-position was better than at the other two positions. These results are explained in terms of the receptor model proposed earlier by others.

Matrix metalloproteinases (MMPs) are well-established targets for several pathologies. In particular, MMP-2 and MMP-13 play a prominent role in cancer progression. In this study, a structure-based screening campaign was applied to prioritize metalloproteinase-oriented fragments. This computational model was applied to a representative fragment set from the publicly available EDASA Scientific compound library. These fragments were prioritized, and the top-ranking hits were tested in a biol. assay to validate the model. Two scaffolds showed consistent activity in the assay, and the isatin-based compounds were the most interesting. These latter fragments have significant potential as tools for the design and realization of novel MMP inhibitors.

Kinetic studies on the loss of water from α-D-glucose monohydrate was written by Ponschke, Michelle A.;House, James E.. And the article was included in Carbohydrate Research in 2011.Recommanded Product: 14431-43-7 This article mentions the following:

Although the dehydration of α-D-glucose monohydrate is an important aspect of several industrial processes, there is uncertainty with regard to the applicable rate law and other factors that affect dehydration. Therefore, the dehydration of three glucose monohydrate samples has been studied using isothermal gravimetric anal. Dehydration follows a one-dimensional contraction (R1) rate law for the majority of kinetic runs, and an activation energy of 65.0 ± 3.9 kJ mol-1 results when the rate constants are fitted to the Arrhenius equation. Fitting the rate constants to the Eyring equation results in values of 62.1 ± 3.7 kJ mol-1 and -77.8 ± 4.7 J mol-1 K-1 for ΔH and ΔS, resp. The impedance effect on the loss of water vapor has also been investigated to determine the values for activation energy, enthalpy, and entropy for diffusion of water. The results obtained for the activation parameters are interpreted in terms of the absolute entropies of anhydrous glucose and the monohydrate.

And the article was included in Chemistry – A European Journal in 2012.COA of Formula: C6H8O2 This article mentions the following:

Several types of chiral hetero- and carbocyclic compounds have been synthesized by using the asym. hydrogenation of cyclic alkenes. N,P-Ligated iridium catalysts reduced six-membered cyclic alkenes, e.g., I, with various substituents and heterofunctionality in good to excellent enantioselectivity, whereas the reduction of five-membered cyclic alkenes, e.g., II, was generally less selective, giving modest enantiomeric excesses. The stereoselectivity of the hydrogenation depended more strongly on the substrate structure for the five- rather than the six-membered cyclic alkenes. The major enantiomer formed in the reduction of six-membered alkenes could be predicted from a selectivity model and isomeric alkenes had complementary enantioselectivity, giving opposite optical isomers upon hydrogenation. The utility of the reaction was demonstrated by using it as a key step in the preparation of chiral 1,3-cis-cyclohexane carboxylates.

Role of water in the polymorphic transitions of small carbohydrates was written by Mathlouthi, Mohamed;Benmessaoud, Ghazi;Roge, Barbara. And the article was included in Food Chemistry in 2012.Quality Control of (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate This article mentions the following:

Crystallization of small carbohydrates (hexoses, alditols, and disaccharides) in solution or from the melt is known to provide different polymorphs mainly due to their affinity with water and their mol. flexibility. Food and pharmaceutical applications sometimes require the use of a specific polymorph especially for its compaction and compression properties. Different factors affect the process of crystallization and make the selection of a polymorph in a straightforward step difficult. As a general rule, the crystallization of the most stable form or the easiest to crystallize is achieved and a polymorphic transition follows. To achieve the transition and obtain the desired crystal form, the control of water activity is needed. Examples of polymorph transitions are described. It is particularly the case for α-D-glucose monohydrate-anhydrous transition and the conversion of β sorbitol to the most stable polymorph γ. Polymorphic transitions were controlled by recording the XRPD patterns of the polymorph submitted to controlled water activity and temperature conditions. The morphol. of crystals was also observed under microscope. FTIR spectra of the polymorphs obtained at different aw values were recorded as well as DSC thermograms. Water vapor sorption isotherms were established and the kinetics of water intake determined An attempt of interpretation of the role of water in polymorphic transitions is made. The flexibility of sorbitol enhanced in presence of water vapor when samples are submitted to humid air seems at the origin of conformation change which induces conformational polymorphism. A difference is noticed between α-D-glucose monohydrate and sorbitol polymorphic transitions due to the difference in their solubility curves (enantiotropic for glucose, monotropic for sorbitol). In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7Quality Control of (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate).
