摘要:
The present invention provides a process for producing aromatic compounds or polymers thereof from a plant material in a short period of time and by a simple procedure. Concretely, the process treats the plant material with supercritical water or subcritical water to liberate aromatic compounds, which are contained in the plant material, and/or aromatic compounds, which have been generated upon decomposition of components of the plant material, to the outside of the plant material, and isolates the liberated aromatic compounds to produce aromatic compounds or polymers thereof.
摘要:
A pyrrolesulfonamide compound having formula (I) wherein the ring P represented by (α) is a pyrrole ring having structure (β) or (γ) wherein A represents alkylene, alkenylene or alkynylene; and Y represents a group (δ) in which W represents CH, C= or N; m stands for 0 or 1 when W is CH or N, or m stands for 1 when W is C=; B represents a specific divalent group; E1 and E2 each independently represents H or lower alkyl; and D represents an aromatic hydrocarbon group or heterocyclic group; $(1,3)$ stands for 0 or 1; the dashed line indicates the presence or absence of a bond; and, when the bond is present, Z2 is not present and Z1 represents H but, when the bond is absent, Z1 represents H and Z2 represents OH or Z1 and Z2 are combined together to represent O or a group NOR5, in which R5 represents H, or alkyl, aralkyl or aryl; and R represents H, alkyl, cycloalkyl, cycloalkyl-alkyl or aralkyl. The compound (1) has been improved in potency, selectivity to receptors other than serotonin-2 receptors, toxicity, side effects and/or the like over medicines reported to date and equipped with α1-blocking action and serotonin-2 receptor antagonistic action in combination.
摘要:
A method of production of 2,4'-dipyridyl derivatives by a cross coupling reaction of a 2-halopyridine derivative and a 4-halopyridine using a nickel complex catalyst and a method of separation of a 2,4'-dipyridyl derivative from a mixture of dipyridyl isomers containing a 2,2'-dipyridyl derivative, 2,4'-dipyridyl derivative, and 4,4'-dipyridyl by using a dilute aqueous copper sulfate solution to insolubilize and remove the 2,2'-dipyridyl derivative and 4,4'-dipyridyl is disclosed.
摘要:
A drinking water dispenser which supplies drinking water from a detachable water container (1). The dispenser is comprised of a hot water tank (3) for heating water supplied from the water container, a chilled water tank (4) for cooling water supplied from the water container, and a supply pipe (2) for connecting the water container and the tanks. A sterilization system (9-11) sterilizes the chilled water tank and the supply pipe by circulating hot water therein.
摘要:
The present invention discloses a process for producing lipid containing omega-9 highly unsaturated fatty acid by culturing in a medium a mutant strain obtained by mutation on a microorganism having the ability to produce arachidonic acid belonging to the genus Mortierella and so forth, in which Δ12 desaturation activity is decreased or lost, but at least one of Δ5 desaturation activity, Δ6 desaturation activity and chain length elongation activity is elevated. Moreover, the present invention also discloses a process for producing omega-9 highly unsaturated fatty acid by collecting omega-9 highly unsaturated fatty acid from the culture or lipid described above.
摘要:
Novel purine nucleosidase derived from Ochrobactrum anthropi microorganisms, a gene system coding therefor, uses therefor and particularly its use in the production of beer.
摘要:
Mutant proteases are obtained with one or more mutation sites in the natural V8 protease protein, and with enzyme activities even in the presence of high urea concentrations. Inactivation of enzyme activity is minimized even in the presence of high concentrations of urea, to thus allow lower amounts of enzyme to be added to urea-containing reaction systems and shorten reaction times. As an additional advantage, the ability to cleave proteins in the presence of high urea concentrations makes it possible to obtain hitherto unobtainable peptide fragments.
摘要:
The present invention provides a pharmaceutical composition for treatment of heart disease based on cardiac hypertrophy, a cause of the onset of heart diseases such as ischemic heart disease and arrhythmia. Consequently, the present invention provides a pharmaceutical composition for treatment of heart disease based on cardiac hypertrophy having for its active ingredient a substance that binds to the NP receptor, GC-A, and is able to accelerate the production of cGMP. Specific examples of active ingredients include natriuretic peptides such as atrial natriuretic peptide and brain natriuretic peptide.
摘要:
The present invention provides an antialopecia agent which is a drug for protecting, reducting or preventing alopecia frequently occurring as the side effect of anticancer agents, inflicts neither any pain nor unpleasantness on patients under the treatment with anticancer agents and has a high safety; and foods or beverages containing this antialopecia agent. The antialopecia agent of the present invention is characterized by containing oolong tea extract as the active ingredient.
