  Synthesis and bioactivity of sphingosine kinase inhibitors and their novel aspirinyl conjugated analogs

  摘要：

  Sphingosine kinase (SphK) is a lipid kinase with oncogenic activity, and SphK inhibitors (SKIS) are known for their anti-cancer activity. Here, we report highly efficient syntheses of SKIs and their aspirinyl (Asp) analogs. Both SKIs and their Asp analogs were highly cytotoxic towards multiple human cancer cell lines: in several cases the Asp analogs were up to three times more effective. Furthermore, they were equally potent inhibitors of SphK. The pharmacokinetic study indicated that SKI-I-Asp cleaved efficiently to form SKI-I and the half-life of SKI-I was increased from similar to 7 h in SKI-I to similar to 10 h in SKI-I-Asp injected mice, thereby prolonging its effect. In summary, the Asp-conjugated SKIs seem to be promising prodrugs of SKIs where delivery in vivo remains a problem. (C) 2010 Elsevier Masson SAS. All rights reserved.

• Synthesis of 1,4-benzothiazinones from acylpyruvic acids or furan-2,3-diones and <i>o</i>-aminothiophenol
  作者：Ekaterina E Stepanova、Maksim V Dmitriev、Andrey N Maslivets

  DOI：10.3762/bjoc.16.193

  日期：——

  Two synthetic approaches to enaminones fused to 1,4-benzothiazin-2-one moiety, which can be interesting in studies on biological activity, chemosensors, and fluorescence, were developed via the reaction of furan-2,3-diones or acylpyruvic acids in the presence of carbodiimides with o-aminothiophenols. The target enaminones were formed together with pharmaceutically interesting 2-hydroxy-2H-1,4-benzothiazin-3(4H)-ones. A selective synthetic approach to 2-hydroxy-2H-1,4-benzothiazin-3(4H)-ones was developed via the solvent-switchable reaction of furan-2,3-diones with o-aminothiophenol. Preliminary biological assays (antimicrobial, acute toxicity) of the new compounds were carried out.
