摘要:
A method of providing a range of flavors to an orally-receivable or ingestible product, the method including adding at least one compound, including salts thereof, of the formula (I) wherein R 1 may be selected from H, OH, O(CH 2 ) 2 OH, OCH 2 OCH 3 and formula (II), R 2 may be selected from a range of 5- and 6-membered heterocyclic rings, and wherein R 3 may be selected from H and OH. The compounds give rise to a wide range of flavors, and some are useful as sweetness enhancers, this allowing sweetener content to be reduced while maintaining sweetness. Also disclosed are orally-receivable or ingestible products including the compounds.
摘要:
This disclosure describes methods of reducing hydroxymethylfurfural ether and ester derivatives to produce, in the case of ethers, 5-(alkoxymethyl)-tetrahydrofuran-2- methanol and (5-alkoxymethyl)-furan-2 -methanol derivatives, or in the case of esters, 5-(acyloxymethyl)- tetrahydrofuran-2 -methanol and 5-(acyloxymethyl)- furan-2- methanol derivatives. Exemplified methods describe purification thereof. In addition, the disclosure relates to n-alkoxy hexane diol compounds, which are derivative compounds useful for replacement of petroleum based carbitol compounds, and can be made by further reduction of the 5-(alkoxymethyl)-tetrahydrofuran-2- methanol and (5-alkoxymethyl)-furan-2-methanol derivatives. The compounds made by the methods of the present teaching are useful as solvents and as starting materials for making other compositions that meet the requirements of bio-based industrial chemicals from renewable resources.
摘要:
The provides compounds for the treatment of sickle-cell disease. In particular, the invention provides 5-membered heterocyclic anti-sickling agents that are highly effective and nontoxic, and methods for their use. The compounds include analogues and derivatives of naturally occurring 5-hydroxymethyl-2-furfuraldehyde, 5-Ethyl-2-furfuraldehyde, 5-Methyl-2furfuraldehyde, and 2-furfuraldehyde, and prodrug forms of the compound.
摘要:
This invention pertains to certain active carbamic acid compounds which inhibit HDAC activity and which have the following formula: wherein: A is an aryl group; Q is an aryl leader group having a backbone of at least 2 carbon atoms; J is an amide linkage selected from: -NR C(=O)- and -C(=O)NR -; R is an amido substituent; and, Q is an acid leader group; and pharmaceutically acceptable salts, solvates, amides, esters, ethers, chemically protected forms, and prodrugs thereof, for use in the treatment of parasitic infections, such as malaria.
摘要:
Verfahren zur Herstellung von substituierten Furancarboxylaten der Formel (I) in der R1 einen gegebenenfalls durch unter den Reaktionsbedingungen inerte Gruppen substituierten, linearen, verzweigten oder cyclischen C 1 -C 18 -Alkyl-, Alkenyl- oder Alkinylrest, einen gegebenenfalls substituierten aromatischen oder heteroaromatischen Rest, und R2 und R3 unabhängig voneinander einenC 1 -C 4 -Alkylrest bedeuten, bei welchem α-Hydroxynitrile der Formel (II) in der R1 wie oben definiert ist, mit β-Dicarbonylverbindungen der Formel (III) in der R2 und R3 wie oben definiert sind, in Gegenwart von Metallhalogeniden als Katalysatoren bei einer Temperatur von 0°C bis 120°C in einem unter den Reaktionsbedingungen inerten, organischem Lösungsmittel umgesetzt werden und nach erfolgter Reaktion der Katalysator abgetrennt und das entsprechende Furancarboxylat isoliert wird.
