Various carboxylic acids, phosphonic acids, sulfonic acids, tetrazoles as well as sulfonylhydantoins were prepared as phosphate mimics of the chiral aminophosphate1-P to act as agonists on the S1P(1) receptor. It was found that amino phosphonates and amino carboxylates are potent S1P(1) binders. beta-Amino acid 11 could be shown to reversibly reduce blood lymphocyte counts in rats after po administration.
