Compounds that have agonist activity at one or more of the SlP receptors are provided. The compounds are sphingosine analogs that, after phosphorylation, can behave as agonists at SlP receptors.
An efficient and practicalarenehydrogenation procedure based on the use of heterogeneous platinum group catalysts has been developed. Rh/C is the most effective catalyst for the hydrogenation of the aromatic ring, which can be conducted in iPrOH under neutral conditions and at ordinary to medium H2 pressures (<10 atm). A variety of arenes such as alkylbenzenes, benzoic acids, pyridines, furans, are
Compounds that have agonist activity at one or more of the SlP receptors are provided. The compounds are sphingosine analogs that, after phosphorylation, can behave as agonists at S lP receptors.
