  A Diastereoselective Oxa-Pictet–Spengler-Based Strategy for (+)-Frenolicin B and epi-(+)-Frenolicin B Synthesis

  摘要：

  An efficient diastereoselective oxa-Pictet - Spengler reaction strategy was developed to construct benzoisochroman diastereomers. The utility of the reaction was demonstrated in the context of both the total synthesis of naturally occurring pyranonaphthoquinones (+)-frenolicin B and epi-(+)-frenolicin B as well as a range of frenolicin precursor analogs. The method is versatile and offers exquisite stereocontrol and, as such, offers a synthetic advance for the synthesis of pyranonaphthoquinone analogs.

  tuberous sclerosis complex to inhibit mTORC1/4E-BP1 signaling axis. FB structure-activity relationship studies reveal a positive correlation between inhibition of 4E-BP1 phosphorylation, ROS-mediated cancer cell cytotoxicity, and suppression of tumor growth in vivo. These findings establish FB as the most potent Prx1/Grx3 inhibitor reported to date and also notably highlight 4E-BP1 phosphorylation status

  Peroxiredoxin 1（Prx1）和glutaredoxin 3（Grx3）是两个主要的抗氧化蛋白，在维持氧化还原稳态以促进肿瘤进展中起着关键作用。在这里，我们确定了典型的吡喃并萘醌天然产物贝宁（B）作为通过活性位半胱氨酸的共价修饰的Prx1和Grx3的选择性抑制剂。FB靶向抑制Prx1和Grx3会导致细胞内的谷胱甘肽水平降低，活性氧（ROS）升高以及伴随的癌细胞生长抑制，主要是通过激活与过氧化物酶体结合的结节性硬化复合物来抑制mTORC1 / 4E -BP1信号轴。FB结构-活性关系研究表明抑制4E-BP1磷酸化，ROS介导的癌细胞的细胞毒性和体内肿瘤生长的抑制之间存在正相关。

  A general, efficient, and common strategy for the synthesis of (−)-juglomycin A, (+)-kalafungin, (+)-frenolicin B, and (+)-deoxyfrenolicin is reported here. The strategy involves the synthesis of a key building block alkyne from a cheap chiral pool material, d-glucono-δ-lactone, Dötz benzannulation, oxa-Pictet-Spengler reaction, and H2SO4-mediated epimerization.
