Sphingosine-1-phosphate is a bioactive lipid signaling molecule and an ago-nistic ligand of five specific G protein coupled receptors named S1P1-5.These receptors play a crucial role in the cardiovascular and immune sys-tem and in angiogenesis. The known compound FTY720 (Fingolimod) is a sphingosine analogue with immunosuppressive effects and was recently approved for treatment of multiple sclerosis in the United States and Russia. The synthetic sphingosine analogue cis-4-methylsphingosine was firstly syn-thesized by R. R. Schmidt and coworkers in 1993 in nine steps. Similar to FTY720 this compound is phosphorylated in biological systems and inhibits the activity of different S1P-receptors, however the spectrum of receptors influended by cis-4-methylsphingosine is slightly different to that influenced by FTY720. Cis-4-methylsphingosine induces apoptosis of neuroblastoma cells.</p> <p><span class="Apple-style-span" style="line-height: 15px; "></span></p> <p><strong>Technology</strong> <br> We offer a rapid and simple method for the stereoselective synthesis of cis-4-methylsphingosine and derivatives thereof in only two steps. The novel synthesis is characterized by using easily accessible starting material, and an overall yield of nearly 30% which is almost 100-fold compared to the synthesis known in the art. Since cis-4-methylsphingosine also influences S1P-receptors like FTY70, however with a slight different spectrum, this com-pound might have similar effects or might support or supplement the activity of FTY720. Thereby cis-4-methysphingosine has a great potential for phar-maceutical application. </p> <b>Benefits:</b>

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
