摘要

Disclosed is a medicament containing a compound of formula (Ia) or (Ib), wherein Z is selected from among a group comprising a covalent bond, at least one at least bivalent heteroatom, a saturated, unsaturated, branched, linear and/or cyclic, substituted or unsubstituted hydrocarbon chain, a saturated or unsaturated, branched, linear and/or cyclic, substituted or unsubstituted hydrocarbon chain containing heteroatoms, or combinations thereof, R^{`1</sup> to R<sup>`4} and R^{``1</sup> to R<sup>``5} each independently represents H, at least one heteroatom, a saturated, unsaturated, branched, linear and/or cyclic, substituted or unsubstituted hydrocarbon chain, a saturated or unsaturated, branched, linear and/or cyclic, substituted or unsubstituted hydrocarbon chain containing heteroatoms, or combinations thereof, the cyclopentadienyl rings are optionally linked by means of any of the radicals R^{``1</sup> to R<sup>``5}, R¹ and R² independently represent H, a heteroatom, a saturated, unsaturated, branched, linear and/or cyclic, substituted or unsubstituted hydrocarbon chain, a saturated or unsaturated, branched, linear and/or cyclic, substituted or unsubstituted hydrocarbon chain containing heteroatoms, or combinations thereof, A`, A`` independently represent F, Cl, BR, I, and/or a physically acceptable acid radical of an organic or inorganic acid, n represents a positive integer, particularly 1, 2, 3, X = O, S, NH, NR<sup>3</sup>, NR<sup>4</sup>R<sup>5</sup>, wherein R<sup>3</sup>, R<sup>4</sup>, and R<sup>5</sup> independently have the meanings indicated for R`¹ to R`<sup>4</sup>, Y = a covalent bond, O, S, or NR<sup>6</sup>, wherein R<sup>6</sup> has the meaning indicated for R<sup>`1</sup> to R^`4.
