  • Patent number: 7247736
    Abstract: The present invention provides a compound capable of binding to the ubiquinone binding site of DHODH which contains a non-aromatic ring system as a core structure, a group capable of interacting with structural elements of subsite 2 or 3 of the ubiquinone binding site of DHODH and a group capable of interacting hydrophobically with structural elements of subsite 1 of the ubiquinone binding site of DHODH. Furthermore, the present invention provides a compound capable of binding to the ubiquinone binding site of DHODH which contains an aromatic ring system as a core structure, a group capable of interacting with residues His 56 and/or Tyr 356 of subsite 3 of the ubiquinone binding site of DHODH and a group capable of interacting hydrophobically with structural elements of subsite 1 of the ubiquinone binding site of DHODH.
