摘要:
The present invention relates to PNA derivatives which carry, at the C terminus, or at both the C and N termini of the PNA backbone, one or more phosphoryl radicals. The phosphoryl radicals carry, where appropriate, one or more labeling groups, groups for crosslinking, groups which promote intracellular uptake, or groups which increase the binding affinity of the PNA derivative for nucleic acids. The invention furthermore relates to a process for preparing the above-mentioned PNA derivatives and to their use as pharmaceuticals or diagnostic agents.
摘要:
The invention provides polyamide-oligonucleotide derivatives of the formula: F[(DNA-Li)q(PNA-Li)r(DNA-Li)s(PNA)t]xF′. In the formula, q, r, s, and t are, independently of one another, zero or 1, where the total of two or more adjacent q, r, s, and t is greater than or equal to 2; and x is 1 to 20. In the formula, DNA is a nucleic acid such as DNA or RNA or a known derivative thereof. Li is a covalent linkage between DNA and PNA, where the covalent linkage comprises a bond or an organic radical with at least one atom from the series consisting of C, N, O, or S. PNA is a polyamide structure which contains at least one nucleotide base that is different from thymine. F and F′ are end groups and/or are linked together by a covalent bond. The invention also provides physiologically tolerated salts of the above formula. The invention further provides a process for preparation of the polyamide-oligonucleotide derivatives of the invention as well as their use as pharmaceuticals, as gene probes, and as primers.
摘要:
The present invention relates to ethyl (2S)-2-(naphthalene-1-sulfonylamino)-3-(4-(2-(1,4,5,6-tetrahydropyrimidin-2-ylcarbamoyl)ethyl)benzoylamino)propionate hemifumarate of formula (I), and to a process for its preparation comprising reacting 4-(2-(1,4,5,6-tetrahydropyrimidin-2-ylcarbamoyl)ethyl)benzoic acid or a derivative thereof and ethyl (2S)-3-amino-2-(naphthalene-1-sulfonylamino)propionate. The compound of formula (I) is a valuable pharmaceutical which can be used, for example, in the treatment or prophylaxis of diseases which can be influenced by inhibiting the vitronectin receptor, in particular of bone diseases such as osteoporosis. The invention furthermore relates to chemical intermediates useful for the preparation of the compound of formula (I).
