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 to R`4 and R``1 to R``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 to R``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, NR3, NR4R5, wherein R3, R4, and R5 independently have the meanings indicated for R`1 to R`4, Y = a covalent bond, O, S, or NR6, wherein R6 has the meaning indicated for R`1 to R`4. |
