P2X3 receptor is an ATP-gated ion channel, mainly localized on peripheral sensory neurons. Currently, several clinical trials are being conducted with P2X3 receptor antagonists for the treatment of chronic pain or cough. To identify a P2X3 lead compound, we reexamined the HTS evaluation compounds and selected dioxotriazine derivatives from which we identified a hit compound. As a result of the hit-to-lead SAR, we obtained lead compound 1 which had a moderate inhibitory effect on P2X3 receptors (IC50, 128 nM). Further improvement of the potency
