| 摘要 |
The invention relates to compounds of formula (I) wherein A respectively and independently from the other A group(s) represents a group comprising a ring of 5-6 ring atoms, said ring carrying at least one amino substituent selected from NH2, NHR, NR2 wherein each radical R is independently selected from CH3 or C2H5, NX2 wherein each substituent X independently represents a group in which the total amount of carbon, nitrogen, oxygen and sulphur atoms is between 1 and 60, formula (II), and formula (III); B respectively and independently from the other B group(s) represents a linker group which joins the ring atoms of two A groups by means of a chain consisting of between 1 and 8 atoms selected from carbon, nitrogen and oxygen; and n represents 2-6. The inventive compounds can be added to nucleic acids and optionally change the tertiary structure thereof. They are thus highly significant in the medical domain.
