work, we discovered a lead compound and conducted initial SAR studies on a novel series of dioxotriazines to identify the compound as one of the P2X3 receptor antagonists. This compound showed high P2X3 receptor selectivity and a stronganalgesic effect. Although not selected for clinical development, the compound was evaluated from various aspects as a tool compound. In the course of the following study
在之前的工作中,我们发现了一种先导化合物,并对一系列新型二氧杂三嗪进行了初步 SAR 研究,以确定该化合物是 P2X3 受体拮抗剂之一。该化合物显示出高 P2X3 受体选择性和强镇痛作用。虽然没有选择用于临床开发,但该化合物作为工具化合物从各个方面进行了评估。在以下研究过程中,基于药代动力学/药效学 (PK/PD) 分析修改了二氧杂三嗪的分子结构。作为这些 SAR 研究的结果,Sivopixant (S-600918) 被确定为具有强效和选择性拮抗活性的临床候选药物 (P2X3 IC 50 , 4.2 nM; P2X2/3 IC 50, 1100 nM) 和对异常性疼痛的大鼠部分坐骨神经结扎模型 (Seltzer model) 有很强的镇痛作用 (ED 50 , 0.4 mg/kg)。
Hydrolytic Kinetic Resolution of Epoxides Catalyzed by Chromium(III)-endo,endo-2,5-diaminonorbornane-salen [Cr(III)-DIANANE-salen] Complexes. Improved Activity, Low Catalyst Loading

The hydrolytickineticresolution (HKR) of terminal epoxides, using chiral chromium(III)-salen catalysts based on DIANANE (endo,endo-2,5-diaminonorbornane), was studied. A broad substrate scope was found for the chromium(III)-DIANANE catalysts, and very low loadings (down to 0.05 mol %) were needed to achieve high enantiomeric purities of both the remaining epoxides and the product diols (up to >99 %

日期:——
Milbemycinspiroacetal 4 was prepared from (4S,5R)-4,5-dimethylpentan-5-olide 5 and (R)-1-(benzyloxymethyl)oxirane by alkylation and stereoselective reductive decyanation of the intermediate spiroacetal cyanohydrin 7.
