Abstract:
:Numerous potent P2X3 antagonists have been discovered and the therapeutic potential of P2X3 antagonism already comprises proof-of-concept data obtained in clinical trials with the most advanced compound. We have lately reported the discovery and optimization of thia-triaza-tricycle compounds with potent P2X3 antagonistic properties. This Letter describes the SAR of a back-up series containing a 4-oxo-quinazoline central ring. The discovery of the highly potent compounds 51 is presented.
