Vitamin K2 has been demonstrated to induce gene expression related to bone formation through a nuclear steroid and xenobiotic receptor (SXR). We synthesized new vitamin K analogues with the same isoprene side chains symmetrically introduced at the 2 and 3 positions of 1,4-naphthoquinone and evaluated the transcriptional activity of the target gene. The transcriptional activity was related to the length
维生素K 2已被证明可通过核甾体和异种生物受体(SXR)诱导与骨骼形成有关的基因表达。我们合成了新的具有相同异戊二烯侧链的新维生素K类似物,这些异戊二烯侧链被对称地引入1,4-萘醌的2和3位,并评估了目标基因的转录活性。转录活性与允许与SXR的配体结合域进行最佳相互作用的侧链长度有关。
