Some phenylalanine (Phe) derivatives had important roles in pharmacology and may be used as pharmaceutical materials and pharmaceutical intermediates. In order to understand the cell toxicity of phenylalanine derivatives, we synthesized L-4-bromo-phenylalanine (Brp), L-4-iodophenylalanine (Ip), L-4-nitro-phenylalanine (Np), L-4-sulfonic-phenylalanine (Sp), L-4-phosphophenylalanine (Pp) and L-4-amino-phenylalanine (Np). We used mass spectrometry (MS), Infrared Spectroscopy (IR) or hydrogen-1 nuclear magnetic resonance spectrum (1H-NMR), and high performance liquid chromatography (HPLC) to test the correction of these products, MTT assay and Hoechst 33258 staining to detect their cell toxic effect on human colon cancer cell HT-29 (HT-29 cells). The results showed that these products were correct and the cytotoxicity of Pp>Ip>Sp and Np>Brp, Ap almost had no effect on HT-29 cells. In addition, Pp, Ip and Sp induced cell apoptosis, the other three kinds of phenylalanine derivatives induced neither apoptosis nor necrosis.

A panel of amino acid analogs and conformationally-restricted amino acids bearing a sulfonic acid were synthesized and tested for their ability to preferentially inhibit the obligate cysteine-glutamate transporter system xc- versus t
