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 Hoechst33258 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
PpIpSp and NpBrp, 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.
一些苯丙氨酸(Phe)衍生物在药理学中具有重要作用,并可能用作药物原料和药物中间体。为了解苯丙氨酸衍生物的细胞毒性,我们合成了L-4-溴苯丙氨酸(Brp)、L-4-碘苯丙氨酸(Ip)、L-4-硝基苯丙氨酸(Np)、L-4-磺酸苯丙氨酸(Sp)、L-4-磷酸苯丙氨酸(Pp)和L-4-氨基苯丙氨酸(Np)。我们通过质谱(MS)、红外光谱(IR)或氢-1核磁共振谱(1H-NMR)以及高效液相色谱(HPLC)检测这些产品的正确性,MTT法和Hoechst33258染色检测它们对人结肠癌HT-29细胞的细胞毒性效应。结果显示,这些产品是正确的,Pp、Ip、Sp和Np的细胞毒性对HT-29细胞基本无影响。此外,Pp、Ip和Sp诱导细胞凋亡,其他三种苯丙氨酸衍生物既不诱导凋亡也不诱导坏死。
