Visible-light-promoted addition of α-bromoacetophenones onto the cyclopropene π-system in the presence of the fac-Ir(ppy)3 catalyst was shown to afford the corresponding 1(4H)-naphthalenones. The syn-carboarylation of the cyclopropene is followed by a cyclopropane ring opening under the basic conditions, allowing the formation of two C–C bonds and the generation of 1(4H)-naphthalenones bearing an all-carbon

Diselenylated indolizines were achieved via intermolecular C–Se formation reaction between 2-methylpyridines, α-bromoketones and diselenides under undivided electrolytic conditions.
energy-minimized conformation of non-selective TRPM2 inhibitor 2-APB as the query structure, which resulted in the discovery of a novel tricyclic TRPM2 inhibitor Z-4 with benzo[d]imidazo[1,2-a]imidazole skeleton. A series of Z-4 derivatives were subsequently synthesized and evaluated using calcium imaging and electrophysiology approaches. Among them, preferred compounds ZA10 and ZA18 inhibited the TRPM2 channel
瞬时受体电位 melastatin 2 (TRPM2) 通道与缺血/再灌注损伤、炎症、癌症和神经退行性疾病有关。然而,缺乏特异性抑制剂阻碍了 TRPM2 靶向治疗药物的开发。为了开发选择性 TRPM2 抑制剂,采用基于三维相似性的筛选策略,使用非选择性 TRPM2 抑制剂 2-APB 的能量最小化构象作为查询结构,从而发现了一种新型三环 TRPM2 抑制剂Z- 4具有苯并[ d ]咪唑[1,2- a ]咪唑骨架。Z-4系列随后使用钙成像和电生理学方法合成和评估衍生物。其中,优选的化合物ZA10和ZA18以微摩尔半最大抑制浓度值抑制TRPM2通道,并对TRPM8通道、TRPV1通道、InsP 3受体和Orai通道表现出TRPM2选择性。构效关系分析为进一步开发选择性 TRPM2 抑制剂提供了有价值的见解。神经保护实验表明ZA10和ZA18能有效降低H 2 O 2诱导的SH-SY5Y细胞死亡率。
