β-Substituted γ-amino acids, β-substituted γ-amino acid derivatives, and β-substituted γ-amino acid analogs and (bio)isosteres and their use as chemotherapeutic agents are disclosed. The β-substituted γ-amino acid derivatives and β-substituted γ-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 β-substituted γ-amino acid derivatives and β-substituted γ-amino acid analogs and (bio)isosteres and methods of using the compounds for treating tumors are also disclosed. The β-substituted γ-amino acid derivatives and β-substituted γ-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. The β-substituted γ-amino acid derivatives and β-substituted γ-amino acid analogs and (bio)isosteres exhibit an increased efficacy on a variety of tumor types.
β-取代的γ-氨基酸,β-取代的γ-氨基酸衍生物,以及β-取代的γ-氨基酸类似物和(生物)同位素及其作为化疗药物的用途被披露。这些β-取代的γ-氨基酸衍生物和β-取代的γ-氨基酸类似物和(生物)同位素是选择性LAT1/4F2hc底物,能够穿过血脑屏障,并在表达LAT1/4F2hc转运蛋白的肿瘤中表现出快速摄取和保留。还披露了合成β-取代的γ-氨基酸衍生物和β-取代的γ-氨基酸类似物和(生物)同位素的方法以及使用这些化合物治疗肿瘤的方法。这些β-取代的γ-氨基酸衍生物和β-取代的γ-氨基酸类似物和(生物)同位素表现出对表达LAT1/4F2hc转运蛋白的肿瘤细胞的改进选择性,并在体内给予受试者时在癌细胞中积累。这些β-取代的γ-氨基酸衍生物和β-取代的γ-氨基酸类似物和(生物)同位素在多种肿瘤类型上表现出增加的疗效。
