Discovery of pyrrolospirooxindole derivatives as novel cyclin dependent kinase 4 (CDK4) inhibitors by catalyst-free, green approach
摘要:
Aiming to develop a new target for the anticancer treatment, a series of 5'H-spiro[indoline-3,4'-pyrrolo [1,2-a]quinoxalin]-2-ones has been synthesized by simple, highly efficient and environmentally friendly method in excellent yields under catalyst-free conditions using ethanol as a green solvent. A simple filtration of the reaction mixture and subsequent drying affords analytically pure products. The synthesized derivatives were evaluated for their antiproliferative activity against five different human cancer cell lines, among the congeners compound 3n showed significant cytotoxicity against the human prostate cancer (DU-145). Flow cytometric analysis revealed that this compound induces cell cycle arrest in the G0/G1 phase and Western blot analysis suggested that reduction in Cdk4 expression level leads to apoptotic cell death. This was further confirmed by mitochondrial membrane potential ((Delta Psi m), Annexin V-FITC assay and docking experiments. Furthermore, it was observed that there is an increase in expression levels of cyclin dependent kinase inhibitors like Cip1/p21 and Kip1/p27. (C) 2015 Elsevier Masson SAS. All rights reserved.
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。

Discovery of XEN907, a spirooxindole blocker of NaV1.7 for the treatment of pain
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
