  • Publication number: 20200055868
    Abstract: The problem to be solved by the present invention is to provide a compound suitable for a pharmaceutical composition, specifically a pharmaceutically composition for treating nocturia. The inventors have assumed that inhibition of nocturnal activity of placental leucine aminopeptidase (P-LAP), i.e. aminopeptidase that cleaves AVP, would maintain and/or increase an endogenous AVP level to enhance the antidiuretic effect, which would contribute to a decreased number of nocturnal voids, and have extensively studied compounds which inhibit P-LAP. As a result, the inventors have found that (2R)-3-amino-2-{[4-(substituted pyridine)-2-yl]methyl}-2-hydroxy-propanoic acid derivatives have excellent P-LAP inhibitory activity. The inventors have evaluated antidiuretic effects in water-loaded rats and have found that the compounds increase endogenous AVP levels by inhibiting P-LAP and consequently reduce urine production.

    Abstract: A phosphorescent chemosensor based on A Gold(I) complex stabilized in an aqueous polymer media. The complex exhibits strong red emission (?max ˜690 nm) in solutions and is sensitive to sub-ppm/nM levels of silver ions. On addition of silver salt to the polymer-complex, a bright-green emissive adduct with peak maximum within 475-515 nm is developed. The silver adduct exhibits a four-fold increase in quantum yield (0.19±0.02) compared to polymer-complex alone (0.05±0.01), along with a corresponding increase in phosphorescence lifetime. The polymer-complex also exhibits sensitivity to higher concentrations (e.g., >1 mM) of other metal ions such as Tl+, Pb2+, and Gd3+. The sensing methodology is simple, fast, and convenient, and the results can be detected by the naked eye. Addition of EDTA restores the red emission of the complex. The complex can distinguish between silver ions and silver nanoparticles and can be used to remediate silver ions from the environment.

    Abstract: The present invention relates to novel polymerizable multivinylaminosilanes which are useful as branching agents for synthetic and natural rubber. The compounds of the invention can be used as such in the polymerization of conjugated diene monomers, optionally together with aromatic vinyl monomers, thus producing polymers, specifically elastomeric polymers, which can favorably be used in rubber articles such as tires.

  • Publication number: 20200055889
    Abstract: Novel steviol glycoside compounds characterized by a first group of four glucopyranose residues attached via the number 13 carbon (C13) of the steviol moiety and a second group of two or three glucopyranose residues attached via the number 19 carbon (C19) of the steviol moiety are described, and exemplified by compounds 1-4. These compounds can be present in a composition with other steviol glycosides (e.g., Reb D and Reb M) to enhance their solubilities. Accordingly, the novel compounds can facilitate the preparation of aqueous compositions having a higher concentration of steviol glycosides. A steviol glycoside composition including one or more of compounds 1-4 can be used as a sweetener composition to sweeten other compositions (sweetenable compositions) such as foods, beverages, medicines, oral hygiene compositions, nutraceuticals, and the like.
