    摘要: The present invention relates to a method of preparing racemic or optically active D or L-±-glycerophosphorylcholine in large amounts by subjecting choline phosphate or a salt thereof, and racemic or optically highly pure (S) or (R)-3-halo-1,2-propanediol to a substitution reaction in a medium at high temperature in the presence of an inorganic base which increases the activity of the reaction. The method for preparing racemic or optically active D or L-±-glycerophosphorylcholine is cost-effective because of the use of starting materials which are inexpensive compared to those in a conventional method. Moreover, the method is simple and convenient because it is performed via a one-pot reaction without a separate purification process. In addition, it enables a large amount of racemic or optically active D or L-±-glycerophosphorylcholine, or a salt thereof, to be quantitatively produced in a medium without side reactions by using the inorganic base which increases the reaction activity.

    摘要: There is provided a protein adsorption inhibitor comprising a compound represented by Formula (1) as an active ingredient. The protein adsorption inhibitor is capable of highly inhibiting non-specific adsorption of a protein such as an antibody or an enzyme to a surface of a base body such as an immune reaction vessel or an assay instrument. There is further provided a coating layer-formed base body having a coating layer containing the protein adsorption inhibitor on the base body. The coating layer-formed base body has an excellent protein adsorption-inhibiting function. There is still further provided a method for inhibiting the adsorption of the protein to the base body comprising forming the coating layer containing the protein adsorption inhibitor on the surface of the base body.

    In Formula (1), X is a hydrogen atom or a methyl group and n is an integer of 9 to 15.
