The specification generally relates to compounds of Formula (I) and pharmaceutically acceptable salts thereof, where A, Z, Y, RA, Linker and v have any of the meanings defined herein. This specification also relates to the use of such compounds and pharmaceutically acceptable salts thereof in methods of treatment of the human or animal body, for example in the prevention or treatment of cancer. This specification also relates to processes and intermediate compounds involved in the preparation of such compounds and to pharmaceutical compositions containing them.
with antibacterialactivity serve as good candidates for developing novel antibacterial drugs which is very urgent and important. In this work, based on the unique scaffold of indirubin, an active ingredient of traditional Chinese medicine formulation Danggui Luhui Wan, we synthesized 29 indirubin-3′-monoximes and preliminarily evaluated their antibacterialactivities. The antibacterialactivity results
多重耐药微生物病原体是一个严重的全球健康问题。具有抗菌活性的新化合物是开发新型抗菌药物的良好候选者,这是非常紧迫和重要的。本工作基于中药当归鹿汇丸活性成分靛玉红独特的支架,合成了29个靛玉红-3'-单肟,并初步评价了其抗菌活性。抗菌活性结果表明,合成的靛玉红-3′-单肟5a-5z和5aa-5ad对金黄色葡萄球菌ATCC25923表现出良好的效力(MIC = 0.4-25.6 μg mL -1 )。其中,我们发现5-F、5-Cl和7-CF 3取代的靛玉红-3′-单肟5r 、 5s和5aa对金黄色葡萄球菌也表现出更好的抗菌效率(MIC高达0.4 μg mL -1 )比原型天然产物靛玉红(MIC = 32 μg mL -1 )。更重要的是,靛玉红-3'-单肟5aa与左氧氟沙星对临床多重耐药金黄色葡萄球菌具有一定的协同作用(分数抑菌浓度指数:0.375)。此外,还进行了电镜观察、PI染色、细胞外钾离子和核酸(260
Construction of C2‐Spirocyclopropyl‐Indolin‐3‐Ones through Base‐Promoted [2+1] Annulation Reaction of Indolin‐3‐ones with Bromosulfonium Salts
base-promoted [2+1] annulationreaction has been developed for the synthesis of the structural diversity C2-spirocyclopropyl-indolin-3-ones. This [2+1] annulation process using simple and easily prepared nucleophilic indolin-3-ones (as C1 synthons) and bromosulfonium salts (as C2 synthons) as substrates, and realized the synthesis of C2-spirocyclopropyl-indolin-3-ones with up to 99 % yield and >20 : 1 dr.
已经开发了一种简单有效的碱促进 [2+1] 环化反应,用于合成结构多样性 C2-spirocyclopropyl-indolin-3-ones。这种[2+1]环化过程以简单易制备的亲核三氢吲哚-3-酮(C1合成子)和溴硫盐(C2合成子)为底物,实现了C2-螺环丙基-3-二氢吲哚-酮的合成高达 99% 的产率和 >20 : 1 dr.
