    摘要: 4-Thio, 4-sulfinyl and 4-sulfonyl proline derivatives of the present invention are antagonists of the VLA-4 integrin and are useful in the treatment, prevention and suppression of diseases mediated by VLA-4-binding and cell adhesion and activation. Moreover, the compounds of the present invention demonstrate significant receptor occupancy of VLA-4 bearing cells after oral administration and are suitable for once-, twice-, or thrice-a-day oral administration. This invention also relates to compositions containing such compounds and methods of treatment using such compounds.
