摘要:
The present invention has an object of providing a method by which two kinds or more of molecules can be separated each other by using dielectrophoretic forces. The present invention comprises two methods. The first method is a method comprising forming a complex substance of a "specific molecule" containing in a sample, and a "substance capable of changing dielectrophoretic properties of the specific molecule", which binds to the "specific molecule" contained therein, and thereby separating the complex substance and the molecules other than the specific molecule in the sample from each other. The second method is a method comprising placing a solution in which two kinds or more of molecules are dissolved under a strong electric field strength, that is, under a nonuniform electric field having an electric field strength of 500 KV/m or higher, by using dielectrophoretic forces.

The present invention relates to a method for deuteration of a compound represented by the general formula [1]:
R 1 ―X―R 2 [1]
wherein, R 1 represents an alkyl group or an aralkyl group, which may have a carbon-carbon double bond and/or triple bond; R 2 represents an alkyl group which may have a carbon-carbon double bond and/or triple bond, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group or a hydroxyl group; X represents a carbonyl group or a hydroxylmethylene group; R 1 and R 2 may form an alicyclic ring together with a carbon atom contained in X; provided that R 2 represents an alkyl group which may have a carbon-carbon double bond and/or triple bond, an aryl group or an aralkyl group when X is a hydroxylmethylene group, comprising reacting the compound represented by the general formula [1] with a heavy hydrogen source in the co-presence of an activated catalyst selected from a palladium catalyst, a platinum catalyst, a rhodium catalyst, a ruthenium catalyst, a nickel catalyst and a cobalt catalyst. The method of the present invention can significantly improve working environment because the deuteration, which has been conventionally carried out under severe conditions such as basic condition, can be carried out under neutral condition. Further, even when the compound represented by the general formula [1] is one having a carbon-carbon double bond or triple bond, the method for deuteration of the present invention enables to efficiently carry out objective deuteration without reduction of said double bond or triple bond.

The present invention relates to a method for deuteration of a heterocyclic ring, which comprises subjecting a compound having a heterocyclic ring to sealed refluxing state in a deuterated solvent in the presence of an activated catalyst selected form a palladium catalyst, a platinum catalyst, a rhodium catalyst, a ruthenium catalyst, a nickel catalyst and a cobalt catalyst. In accordance with a method of the present invention, a hydrogen atom belonging to a heterocyclic ring of a compound having a heterocyclic ring can be very efficiently deuterated because temperature of deuteration reaction can be maintained at higher than boiling point of the solvent. Further, a method for deuteration of the present invention can be applied widely to deuteration of various compounds having a heterocyclic ring which are liable to decomposition under supercritical conditions or acidic conditions, leading to industrial and efficient deuteration of a compound having a heterocyclic ring.

The present invention relates to a method for efficiently producing an aminoalkylsulfonic acid in an industrial scale, and provides "a process for producing an aminoalkylsulfonic acid represented by the general formula [2]: wherein R 1 and R 2 are each independently a hydrogen atom, an alkyl group, an aryl group or an aralkyl group; and R 3 and R 4 are each independently a hydrogen atom or an alkyl group, comprising reacting an aminoalkylsulfonate salt represented by the general formula [1]: wherein M is an alkali metal atom, an organic ammonium ion or an ammonium ion; and R 1 to R 4 are the same as described above, an aqueous solution thereof, or a solution dissolving any one of them in a water-soluble organic solvent, selected from alcohols having 1 to 3 carbon atoms, carboxylic acids having 2 to 12 carbon atoms and dimethylformamide, with an organic acid; and a method of salt exchange for an aminoalkylsulfonate salt represented by the general formula [1']: wherein M' is an alkali metal atom, an organic ammonium ion or an ammonium ion; and R 1 and R 4 are the same as described above, comprising reacting an aminoalkylsulfonate salt represented by the above general formula [2] with a hydroxide represented by the general formula [6]:
M'OH [6]
wherein M' is the same as described above, in an alcohol or water".

The present invention relates to a method for deuteration of a compound having an aromatic ring, using an activated catalyst, and the method comprises reacting a compound having an aromatic ring with heavy hydrogen source in the presence of an activated catalyst selected from a platinum catalyst, a rhodium catalyst, a ruthenium catalyst, a nickel catalyst and a cobalt catalyst.
摘要:
The present invention discloses a method for determining a risk of atherosclerosis or future development of atherosclerotic complications by measuring an amount of a soluble Fcγ receptor IIIa Mφ derived from macrophage (hereafter abbreviated as sFcγRIIIa Mφ ) in a blood sample from patients by using an antibody specifically recognizing FcγRIIIa Mφ , and determining the risk on the basis of the result of the measurement, a kit for measuring an amount of sFcγRIIIa Mφ and a kit for determining a risk of development of atherosclerosis or future development of atherosclerotic complications. A determination method of the present invention is a non-invasive method with greatly mitigated patient burden compared with a conventional cardiac catheterization method, because it is a method by measuring an amount of sFcγRIIIa Mφ in a blood sample, which is a novel predictive marker of atherosclerosis. Furthermore, the present method can also determine a risk of coming down with atherosclerotic complications in the future for a case of superficially healthy but with progressing atherosclerosis internally.
