Definitions
- Diazine azole derivatives their manufacture and use as pharmaceutical agents
- the present invention relates to novel diazine azole derivatives, to a process for their manufacture, pharmaceutical compositions containing them and their manufacture as well as the use of these compounds as pharmaceutically active agents.
- tumor inhibitors are due to a very wide variety of mechanisms, only some of which are known. It is not unusual for known tumor drugs to be found to have new mechanisms of action. This is also to be expected in the case of the compounds according to the invention.
