2-(Alkylamino)benzonitriles were synthesized via a rhodium-catalyzed cyanation on the aryl C–H bond and subsequent denitrosation of N-nitrosoarylamines using a removable nitroso as the directing group, in which N-cyano-N-phenyl-p-methylbenzenesulfonamide (NCTS) was used as the “CN” source. Various substituents on the aryl ring and amino group of N-nitrosoarylamines tolerated the reaction, and the corresponding

spectrum of benzo[h]naphtho[1,8-bc][1,6]naphthyridine. This reaction allows the formation of three new chemical bonds through addition of methyl radical across alkene double bond, intramolecularaddition of carbon-centered radical to cyano group and cyclization of the iminyl radical cascade, and features simple reaction system and wide substrate scope.

describe the early stages of a fragment-based leaddiscovery (FBLD) project for a recently elucidated synthetic lethal target, the PRMT5/MTA complex, for the treatment of MTAP-deleted cancers. Starting with five fragment/PRMT5/MTA X-ray co-crystal structures, we employed a two-phase fragment elaboration process encompassing optimization of fragment hits and subsequent fragment growth to increase potency
在这里,我们描述了基于片段的先导发现 (FBLD) 项目的早期阶段,该项目针对最近阐明的合成致死靶点 PRMT5/MTA 复合物,用于治疗MTAP缺失的癌症。从五个片段/PRMT5/MTA X 射线共晶结构开始,我们采用了两阶段片段加工过程,包括优化片段命中和随后的片段生长,以提高效力、评估合成易处理性并实现基于结构的药物设计。确定了两个先导系列,其中一个导致了临床候选 MRTX1719 的发现。
