    Abstract: Provided are: a novel chiral 4-boronophenylalanine (BPA) derivative; a method for producing the derivative; and a method for producing 18F-2-fluoro-4-borono-L-phenylalanine (18F-labeled BPA; 18F-BPA) using the derivative. A compound represented by formula (1) is prepared. In the formula, R represents BR3R4, BX3− or BX3−M+ (wherein X represents a halogen atom, and M+ represents a monovalent monoatomic cation, a polyatomic cation or a complex cation); R1 represents a hydrogen atom or a protecting group PG1; R2 represents a hydrogen atom or a protecting group PG2; R3 and R4 independently represent OH, or R3, R4 and B together form a ring that serves as a protecting group; and Y represents a halogen atom, NO2, NH2, Sn(R6)3, N═N—NR7R8, OSO2R9, NR10R11, a substituted or unsubstituted phenyliodo group or a substituted or unsubstituted heterocyclic iodo group. The compound is reacted with a fluorination reagent to prepare 18F-labeled BPA.

    Abstract: Provided are new compounds that can have the property of being specifically taken up into cancer cells. In the present invention, novel 4-borono-phenylalanine derivatives, borono-phenylalanine derivatives having a heterocyclic skeleton, borono-phenylalanine derivatives having a fused ring structure, or pharmaceutically acceptable salts thereof are prepared. These compounds have the property of being taken up specifically by LAT1 and thus easily taken up specifically by cancer cells in the evaluation of LAT1 and LAT2 selective uptake, and can be conveniently used for neutron capture therapy and the like. A typical example is a compound represented by the following formula (I) or a pharmaceutically acceptable salt thereof.

    Abstract: It is an object of the present invention to provide a substance usable as an anticancer agent or DDS, which has intracellular stability, which is capable of evading side effects from functional disorder with respect to normal cells, or which has instantaneous effect. The inventors developed a novel chimeric peptide targeting cancer cells which overexpress EGFR or the like using a binding peptide such as a peptide sequence binding to EGFR, and a lytic peptide sequence, thereby solving such an object. Particularly, by using a chimeric peptide including an EGF receptor-binding peptide or the like and a cytotoxic peptide, this object was solved.
