Popis: | FTY720 ( 1 ) is a novel immunosuppressant (immunomodulator), derived from ISP-I ( 2 : myriocin and thermozymocidin). To clarify the pharmacokinetic properties of 1 , antibodies against 1 were prepared and a competitive enzyme immunoassay (EIA) was developed. Two kinds of haptens, 3 and 4 , for 1 were synthesized and coupled to ovalbumin (OVA). Rabbits were immunized with 3 -OVA or 4 -OVA, and corresponding antibodies were obtained. Both antibodies recognized the 2-amino-2-(2-phenylethyl)propane-1,3-diol moiety in 1 . Using the anti- 3 -OVA antibody, a competitive EIA for 1 was developed and evaluated. The range of quantification by the EIA was 0.06–10 ng/mL. The application of the EIA has enabled us to measure the FTY720 concentration in serum after oral administration of 1 (1 mg/kg) to rats. |
