摘要:
This invention relates to urea derivatives and salts thereof which is useful as an active ingredient of pharmaceutical preparations. The urea derivatives of the present invention has an excellent activity as VR1 antagonist and useful for the prophylaxis and treatment of diseases associated with VR1 activity, in particular for the treatment of urge urinary incontinence, overactive bladder, chronic pain, neuropathic pain, postoperative pain, rheumatoid arthritic pain, neuralgia, neuropathies, algesia, nerve injury, ischaemia, neurodegeneration, stroke, incontinence and/or inflammatory disorders.
摘要:
A light-alloy casting producing method is provided in which a T6 treatment can be given to a light-alloy casting without any heat treatment furnace (or aging furnace), so that its mechanical properties such as tensile strength can be adequately heightened. This method includes: a mold preparing process of preparing a mold which includes a sand mold part which is provided with a riser section, and a metal mold part which is disposed apart from the riser section, the sand mold part and the metal mold part forming a cavity section; a casting process of pouring a molten light-alloy into the cavity section of the mold; a metal mold part removing process of separating the metal mold part from a casting which is formed by pouring; a quenching process of bringing a cooling medium into contact with the surface of the casting from which the metal mold part is removed, and thereby, cooling the casting rapidly; an aging process of covering the metal mold part-removed section of the casting with a heat keeper, and keeping the whole casting which is surrounded with the sand mold part and the heat keeper at an aging temperature for a predetermined period of time, using the heat which is kept by a riser portion.
摘要:
The purpose of the present invention is to provide an agglutination enhancer which shows superior agglutination enhancing effect to those of conventional immunoagglutination enhancers, and the present invention relates to an agglutination enhancer for an immunoagglutination measurement method which comprises a polymer having a monomer unit shown by the following general formula [1]: (Wherein R1 represents a hydrogen atom or a methyl group; R2 and R3 independently represent a methyl group or an ethyl group, respectively; X represents —NH— or an oxygen atom; n represents an integer of 1 to 6; and m represents an integer of 1 to 3), and an immunoagglutination measurement method in which, in the coexistence of the above-described agglutination enhancer for immunoagglutination measurement method, an antibody against analyte or an antigen for the analyte is brought into contact with the analyte to cause an antigen-antibody reaction.
摘要:
This invention relates to tetrahydro-Naphthalene derivatives and salts thereof which are useful as an active ingredient of pharmaceutical preparations. The tethrahydro—Naphthalene derivatives of the present invention have excellent activity as VR1 antagonist and useful for the prophylaxis and treatment of diseases associated with VR1 activity, in particular for the treatment of urinary incontinence, overactive bladder, urge urinary incontienence, chronic pain, neuropathic pain, post-operative pain, rheumatoid arthritic pain, neuralgia, neuropathies, algesia, nerve injury, ischaemia, neurodegeneration, stroke, inflammatory disorders, asthma and COPD.

摘要:
This invention is to provide a process for producing 2-amino-4,6-disubstituted nicotinic acid ester analogs and salts thereof, comprising the reaction shown by the following scheme. The ester analogs can be prepared in one pot, and in good yield by using tertiary alkyl cyanoacetate. Furthermore, the method is useful for preparing derivatives of various analogs of the ester, e.g. alkyl substituted and aryl substituted analogs.
摘要:
Two beams 17 and 18 perpendicular to a moving trajectory Q are formed in an intake port opening 14 of a cylinder head material to serve as margins for interfering with deformation of the opening 14 due to softening of the material, thereby a deformation of the material and a void caused by the deformation can be prevented in the frictional stirring with the rotary tool.
摘要:
A purified luciferase from Luciola lateralis is disclosed. The enzyme is characterized by having properties including: an optimum pH range of 7.5 to 9.5, an optimum temperature range of 0.degree. C. to 50.degree. C., and that the enzyme does not act on ADP, CTP, UTP, and GTP. The enzyme is purified by using a process which includes: gel filtration chromatography, hydroxyapatite column chromatography, and a tris(hydroxy)aminomethane-hydro-chloric acid buffer.
