Pt-containing compound, process for its preparation, and application of such compounds
First Claim
1. Pt-containing compound for use in detectably labeling a nucleic acid molecule, with the formula {PtII (w)(x)(y)(z)} or {PtIV (u)(v)(w)(x)(y)(z)}, with the structural formula 1 or 2:
- ##STR4## in which u, v, w, x, y, and z represent whether or not the same whether or not covalently interconnected ligands, of which no more than one of the ligands is a leaving ligand selected from the group consisting of halide, sulfate, nitrate, phosphate, carbonate, ethylnitrate, phosphonates, oxalates, citrates, H2 O ROH, RO-, in which R is an organic residual group; and
substituted sulfoxides R1 R2 SO, in which R1 and R2 whether or not equal to each other are organic residual groups, at least one of the ligands is a detectable marker group, and the remaining ligands are one or more ethylenediamine moieties.

Abstract
Pt-containing compound with the formula {PtII (w)(x)(y)(z)} or {PtIV (u)(v)(w)(x)(y)(z)}, wherein u, v, w, x, y and z represent whether or not the same whether or not interconnected ligands, of which at least one is a leaving ligand and at least one of the remaining ligands represents a detectable marker group. According to the invention (CH3)2 SO, Cl or H2 O appears to be suitable as a leaving ligand while as detectable marker group a fluorescent group merits preference and is the ligand fluorescein or tetramethyl rhodamine. A suitable Pt-containing compounds is {Pt(ethylenediamine)(Me2 SO)(fluorescein-NH(CS)-NHCH3)} (PtF). Further, the invention comprises a process for the preparation of the Pt-containing compounds, where the Pt-containing compounds are prepared in a manner known per se for analogous compounds.

11. A method for the diagnosis of viral, bacterial, or parasitic infections, detection of genetic deviation, or detection of gene expression, comprising detecting a detectably labeled nucleic acid specific for a viral, bacterial, or parasitic infection, genetic deviation, or gene expression, wherein said detectably labeled nucleic acid is labeled with a Pt-containing compound with the formula {PtII (w)(x)(y)(z)} or {PtIV (u)(v)(w)(x)(y)(z)}, with the structural formula 1 or 2:
- ##STR6## in which u, v, w, x, y and z represent whether or not the same whether or not covalently interconnected ligands, of which no more than one of the ligands is said nucleic acid molecule, at least one of the ligands is a detectable marker group, and the remaining ligands are one or more ethylenediamine moieties.
