    • The invention concerns rhodamine derivatives of the general formulae in which Ca-Cd each denote a C atom, and Ca and Cb as well as Cc and Cd are either linked together by a single bond or by a double bond; X1 to X16 denote independently of one another halogen, sulfonic acid, hydrogen or an alkyl residue with 1-20 C atoms in which the alkyl residue can be substituted with one or several halogen or sulfonic acid residues; R1 and R2 are either identical or different and denote either hydrogen, alkyl with 1-20 C atoms, polyoxyhydrocarbyl units, phenyl or phenylalkyl with 1-3 carbon atoms in the alkyl chain in which the alkyl and/or phenyl residues can be substituted by one or several hydroxy, halogen, sulfonic acid, amino, carboxy or alkoxycarbonyl groups where alkoxy can have 1-4 carbon atoms, R1 contains at least one activatable group, R2 and X4 can be optionally linked together via a bridge composed of 0-2 C atoms. In contrast to the prior art, these compounds are characterized in that A1, A2 and A3 can independently of one another denote hydrogen, cyano, halogen and sulfonic acid; B1 denotes either halogen, cyano or hydrogen; B2 denotes hydrogen, amide, halogen and an alkyl residue with 1-20 C atoms. In addition the invention concerns activated rhodamine derivatives, correspondingly conjugated biomolecules and their use in diagnostic systems.
    • 本发明涉及一般式的罗丹明衍生物,其中Ca-Cd各自表示C原子,Ca和Cb以及C c和Cd通过单键或双键连接在一起; X1至X16彼此独立地表示卤素,磺酸,氢或具有1-20个C原子的烷基残基,其中烷基残基可被一个或几个卤素或磺酸残基取代; R 1和R 2可以相同或不同,表示氢,具有1-20个C原子的烷基,聚氧烃基单元,烷基链中具有1-3个碳原子的苯基或苯基烷基,其中烷基和/或苯基残基可被 一个或几个羟基,卤素,磺酸,氨基,羧基或烷氧基羰基,其中烷氧基可以具有1-4个碳原子,R 1包含至少一个可活化基团,R 2和X 4可以任选地通过由0-2 C原子。 与现有技术相反,这些化合物的特征在于,A1,A2和A3可以彼此独立地表示氢,氰基,卤素和磺酸; B1表示卤素,氰基或氢; B2表示氢,酰胺,卤素和具有1-20个C原子的烷基。 此外,本发明涉及活化的罗丹明衍生物,相应的共轭生物分子及其在诊断系统中的用途。
