AMINO ACID PRECURSOR, AMINO ACID, AND PRODUCTION METHOD FOR AMINO ACID, AND PET DIAGNOSTIC TRACER USING AMINO ACID

摘要

Disclosed is an amino acid that can be prevented from being incorporated into normal cells and selectively incorporated into tumor cells, even when used in a PET diagnostic tracer. Also disclosed are an amino acid precursor, a production method for the amino acid, and a PET diagnostic tracer that uses the amino acid. The amino acid of the present invention is represented by formula (II). The amino acid of the present invention is, for example, useful as a PET diagnostic tracer or as a building block for a pharmaceutical intermediate.
