  genetic evidence has identified the voltage-gated sodium channel NaV1.7 as an attractive target for the treatment of pain. We initially identified naphthalene sulfonamide 3 as a potent and selective inhibitor of NaV1.7. Optimization to reduce biliary clearance by balancing hydrophilicity and hydrophobicity (Log D) while maintaining NaV1.7 potency led to the identification of quinazoline 16 (AM-2099).

  人类遗传证据已将电压门控钠通道Na V 1.7确定为治疗疼痛的引人注目的靶标。我们最初确定萘磺酰胺3是Na V 1.7的有效和选择性抑制剂。通过在保持Na V 1.7效力的同时平衡亲水性和疏水性（Log D）来降低胆汁清除率的优化导致了对喹唑啉16（AM-2099）的鉴定。化合物16在大鼠和狗中显示出良好的药代动力学特征，并在口服给药后在小鼠行为模型中证明了组胺诱导的scratch痒的剂量依赖性降低。

This method could deliver various spiro[indene‐1,3′‐indole] compounds in good yields (up to 95 % yield) with up to 98 % ee. The salient features of the transformation

  PISP in hexagonal ring-fused NBN-π systems, leading to the formation of excimers. Notably, the scope of PISP compounds is still quite limited, and PISP has never been observed in NBN-π systems before. These hexagonal ring-fused NBN-π systems constitute a novel PISP molecular library and appear to be a new class of aggregation-induced excimer emission (AIEE) materials. Finally, the AIEE behavior of these

  尽管具有氮-硼-氮 (NBN) 部分的多环芳烃 (PAH) 由于其有趣的电子和光电特性而最近引起了极大的兴趣，但迄今为止报道的所有 NBN 稠合 π 系统都被称为 NBN-二苯并苯和是通过亲电芳香取代合成的。NBN-phenalenes 的合成仍然具有挑战性，过渡金属催化从未被用于构建 NBN 嵌入的 π-支架。在此，开发了一种钯催化的环化/双环化策略，用于合成各种五边形和六边形环稠合 NBN-phenalenes 和 half-NBN-phenalenes。我们论文中介绍的所有 NBN 嵌入的 π 支架在溶液和固态下都发荧光。进一步的研究表明，五元 NBN 环表现出传统发光体的特性，而六元 NBN 环通常会经历光诱导结构平面化 (PISP)​​，并在溶液中不同浓度时表现出不同颜色和量子产率的荧光。时间分辨光谱和 TD-DFT 计算表明，激发态芳构化是六方环稠合 NBN-π 系统中 PISP

  An efficient method has been developed to synthesize 6-fluoroalkyl-phenanthridines via the palladium-catalyzed tandem cyclization of fluorinated imidoyl chlorides with 2-bromophenylboronic acid. This methodology facilitates the rapid synthesis of 6-fluoroalkyl-phenanthridines through dual C–C bond formation in an oxidant-free one-pot manner.
