Methods and compositions of catalysts for sulfoxidation reaction processes are disclosed. The sulfoxidation reaction process can be performed in an aqueous medium, and the catalysts can be recycled for further use. In some embodiments, a method of making a catalyst may include contacting a transition metal compound with an oxidizing agent to form a first solution, contacting a carboxylic acid compound with a cationic surfactant to form a second solution, mixing the first solution and the second solution to form a precipitate, and isolating the precipitate.
The present invention relates to immunosuppressant, process for their production, their uses and pharmaceutical compositions containing them. The invention provides a novel class of compounds useful in the treatment or prevention of diseases or disorders mediated by lymphocyte interactions, particularly diseases associated with EDG receptor mediated signal transduction.
