series of NaV1.7blockers were developed. Following the elimination of undesirable structural features, preliminary optimization of the oxindole C-3 and N-1 substituents afforded the simplified analogue 9b, which demonstrated a 10-fold increase in target potency versus the original HTS hit. A scaffold rigidification strategy then led to the discovery of XEN907, a novel spirooxindole NaV1.7blocker. This
从通过高通量筛选活动确定的羟吲哚2a开始,开发了一系列Na V 1.7阻滞剂。在消除了不良的结构特征之后,对羟吲哚C-3和N-1取代基进行了初步优化,得到了简化的类似物9b,与原始HTS命中相比,该类似物的目标效能提高了10倍。脚手架的加固策略随后导致了XEN907的发现,XEN907是一种新型螺氧吲哚Na V 1.7阻滞剂。这种先导化合物的效能又提高了10倍,代表了进一步优化工作的有希望的结构。
Dearomative [4+2] Cycloaddition of Oxindole‐Embedded<i>ortho</i>‐Quinone Methides with 2,5‐Dialkylfurans
2,5‐Dialkylfurans were facilely converted to pharmaceutically significant spiro[chroman‐4,3′‐oxindole] scaffolds via an organocatalytic dearomative [4+2] cycloaddition with oxindole‐embedded ortho‐quinonemethides. This method featured mild reaction conditions, simple operation, good yields, and excellent diastereoselectivities.
such as drug resistance. Introducing dualinhibiting effect is a valid approach to solve this trouble and bring advantages including wide adaptability, favorable safety and superiority of combination. We started from potential DNA Gyrase inhibitory backbone isatin to develop oxoindolin derivatives as atypical dual Gyrase (major) and FabH (assistant) inhibitors via a two-round screening. Aiming at blocking
A light-driven, catalyst- and additive-free photoenolization/nucleophilic addition reaction for the synthesis of 3-benzyl-3-hydroxyindolin-2-ones is presented. In this reaction, 2-methylbenzophenones undergo light-induced enolization process to afford hydroxy-o-quinodimethanes (hydroxy-o-QDMs), which are then immediately captured by the electrophilic isatins. The reaction utilizes green and clean light
