  Novel natural product-based cinnamates and their thio and thiono analogs as potent inhibitors of cell adhesion molecules on human endothelial cells

  摘要：

  In the present study, we report the design and synthesis of novel analogs of cinnamates, thiocinnamates and thionocinnamates and evaluated the potencies of these analogs to inhibit TNF-alpha induced ICAM-1 expression on human endothelial cells. By using whole cell-ELISA, our screening data demonstrated that ethyl 3',4',5'-trimethoxythionocinnamate (ETMTC) is the most potent inhibitor of TNF-alpha induced ICAM-1, VCAM-1 and E-selectin. As functional consequences, ETMTC abrogated TNF-alpha induced adhesion of neutrophils to the endothelial monolayer. Structure activity relationship studies revealed the critical role of the chain-length of the alkyl group in the alcohol moiety, number of methoxy groups in the aromatic ring of the cinnamoyl moiety and the presence of the alpha, beta- C-C double bond in the thiocinnamates and thionocinnamates.

  A novel synthesis of trimethylsilyldiazomethane (TMSCHN2 ) by diazotization of trimethylsilylmethylamine (TMSCH2 NH2 ) is reported using batch and continuous flow synthesis. The latter affords a daily production of 275 g (2.4 mol) of TMSCHN2 . Other silylated methylamines were also successfully reacted under the developed reaction conditions to furnish various silicon-bearing diazomethane reagents

  报道了使用间歇和连续流合成通过三甲基甲硅烷基甲胺（TMSCH 2 NH 2）的重氮化而新颖地合成三甲基甲硅烷基重氮甲烷（TMSCHN 2）。后者每天可生产275克（2.4摩尔）TMSCHN 2。在开发的反应条件下，其他甲硅烷基化的甲胺也成功地进行了反应，以提供各种含硅的重氮甲烷试剂。通过公开间歇和连续流一锅酯化和1，3-偶极环加成方法，突出了该方法的适用性。此外，公开了在连续流动中羧酸与甲硅烷基化和取代的甲胺的高产率酯化。最后，报道了用于制备TMSCHN 2的2-MeTHF溶液的后处理和纯化程序，该溶液可用于铑催化的亚甲基化和同源化反应。
