Abstract: ?-Substituted ?-amino acids, ?-substituted ?-amino acid derivatives, and ?-substituted ?-amino acid analogs and (bio)isosteres and their use as chemotherapeutic agents are disclosed. The ?-substituted ?-amino acid derivatives and ?-substituted ?-amino acid analogs and (bio)isosteres are selective LAT1/4F2hc substrates and exhibit rapid uptake and retention in tumors expressing the LAT1/4F2hc transporter. Methods of synthesizing the ?-substituted ?-amino acid derivatives and ?-substituted ?-amino acid analogs and methods of using the compounds for treating cancer are also disclosed. The ?-substituted ?-amino acid derivatives and ?-substituted ?-amino acid analogs exhibit selective uptake in tumor cells expressing the LAT1/4F2hc transporter and accumulate in cancerous cells when administered to a subject in vivo. The ?-substituted ?-amino acid derivatives and ?-substituted ?-amino acid analogs and (bio)isosteres exhibit cytotoxicity toward several tumor types.

Abstract: ?-Substituted ?-amino acids, ?-substituted ?-amino acid derivatives, and ?-substituted ?-amino acid analogs and (bio)isosteres and their use as chemotherapeutic agents are disclosed. The ?-substituted ?-amino acid derivatives and ?-substituted ?-amino acid analogs and (bio)isosteres are selective LAT1/4F2hc substrates, capable of passing through the blood-brain barrier, and exhibit rapid uptake and retention in tumors expressing the LAT1/4F2hc transporter. Methods of synthesizing the ?-substituted ?-amino acid derivatives and ?-substituted ?-amino acid analogs and (bio)isosteres and methods of using the compounds for treating tumors are also disclosed. The ?-substituted ?-amino acid derivatives and ?-substituted ?-amino acid analogs and (bio)isosteres exhibit an improved selectivity toward tumor cells expressing the LAT1/4F2hc transporter and accumulate in cancerous cells when administered to a subject in vivo.
