human P2X3 receptor antagonist compound that can penetrate the central nervous system, the compound collection of Gedeon Richter was screened. A hit series of tricyclic compounds was subjected to a rapid, two-step optimization process focusing on increasing potency, improving metabolic stability and CNS penetrability. Attempts resulted in compound 65, a potential tool compound for testing P2X3 inhibitory
嘌呤能P2X3受体是三聚体配体门控离子通道,其拮抗作用是吸引人的但具有挑战性且尚未得到充分验证的药物开发构想。为了鉴定可穿透中枢神经系统的口服活性,有效的人P2X3受体拮抗剂化合物,筛选了Gedeon Richter的化合物集合。对命中的三环化合物系列进行了快速的两步优化过程,重点是提高效力,改善代谢稳定性和CNS渗透性。尝试产生了化合物65,这是一种用于在体内测试P2X3抑制作用的潜在工具化合物。
