Pyridopyrazines and their use as modulators of kinases
The invention relates to pyrido[2,3-b]pyrazines of the general formulae (I) and (II), and to their preparation and use as medicaments, especially for the treatment of malignant disorders and other disorders based on pathological cell proliferations.
1. A pyrido[2,3-b]pyrazine of formulae (I) selected from the group consisting of:
2. A process for producing a medicament, comprising processing one or more pyrido[2,3-b]pyrazines according to claim 1 with pharmaceutically acceptable carriers and/or excipients to give pharmaceutical formulations in a therapeutically usable form.
3. A composition which comprises a pharmacologically active amount of at least one pyrido[2,3-b]pyrazine compound according to claim 1 and a pharmaceutically acceptable carrier and/or excipient.
4. The composition according to claim 3 , wherein the pyrido[2,3-b]pyrazine is present in a unit dose of 0.001 mg to 100 mg per kg of body weight of a patient.
5. 4-[6-(3-ethylurea)pyrido[2,3-b]pyrazin-3-yl]phenyl 2-methoxyethyl carbonate
6. A process for producing a medicament, comprising processing 4-[6-(3-ethylurea)pyrido[2,3-b]pyrazin-3-yl]phenyl 2-methoxyethyl carbonate according to claim 5 with pharmaceutically acceptable carriers and/or excipients to give pharmaceutical formulations in a therapeutically usable form.
7. A composition which comprises a pharmacologically active amount of 4-[6-(3-ethylurea)pyrido[2,3-b]pyrazin-3-yl]phenyl 2-methoxyethyl carbonate according to claim 5 and a pharmaceutically acceptable carrier and/or excipient.
8. The composition according to claim 7 , wherein the 4-[6-(3-ethylurea)pyrido[2,3-b]pyrazin-3-yl]phenyl 2-methoxyethyl carbonate is present in a unit dose of 0.001 mg to 100 mg per kg of body weight of a patient.
