Sphingosine kinase 1 (SK1) is over-expressed in many cancers where it provides a selective growth and survival advantage to these cells. SK1 is thus a target for anti-cancer agents that can promote apoptosis of cancer cells. In previous work, we synthesized a novel allosteric SK1 inhibitor, (S)-FTY720 vinylphosphonate. We now report a more expeditious route to this inhibitor which features B-alkyl
鞘氨醇激酶 1 (SK1) 在许多癌症中过度表达,为这些细胞提供选择性生长和存活优势。因此,SK1 是可以促进癌细胞凋亡的抗癌剂的靶标。在之前的工作中,我们合成了一种新型的变构 SK1 抑制剂,( S )-FTY720 乙烯基膦酸酯。我们现在报告了一种更快速的抑制剂途径,该途径以 B-烷基 Suzuki 偶联为关键步骤,并表明用叠氮基取代 (S)-FTY720 乙烯基膦酸酯中的氨基可将乙烯基膦酸酯从变构抑制剂转化为活化剂SK1 在低微摩尔浓度。我们的结果证明了使用(S)-FTY720 乙烯基膦酸酯支架来定义 SK1 变构位点的结构-活性关系。
