Synthesis of Orthogonally Protected Bis(aminomethyl)malonic Acid, and Its Use as a Key Building Block in the Preparation of Cyclic Peptide Conjugates of 2-N-Alkyl-1,2,3,4-tetrahydroisoquinoline on a Solid Support
Orthogonally protected bis(aminomethyl)malonicacid (1) was synthesized and used as a key building block for the construction of cyclic peptide conjugates on a solid support. The applicability of the building block was demonstrated by preparation of 19 backbone cyclized/branched peptide conjugates of N-2-alkyl-5-(3-aminopropoxy)-1,2,3,4-tetrahydroisoquinoline as stereoisomeric pairs.

It is an object of the present invention to provide a method for carrying out on a same biosensor both of the measurement of the amount of a physiologically active substance immobilized on a biosensor substrate and the measurement of the biological activity of the above physiologically active substance, thereby analyzing the interaction of a substance with the above physiologically active substance that maintains its activity. The present invention provides a measurement method using a biosensor substrate, wherein both the amount of a physiologically active substance immobilized on the substrate and the biological activity of the physiologically active substance immobilized on the substrate are measured on said same biosensor substrate.
