of indirubin-3-oximes, the compounds were modified by attaching a quaternary ammonium group at the oxime moiety. Exploring the prodrug concept, an oxime ester with acetyl-l-carnitine was prepared, and the rate of its hydrolysis was investigated to assess its suitability for clinical administration. In addition, the cytotoxic potency of new stable oxime ethers with a choline moiety and their influence

This study presents the design, synthesis, and characterization of bisindole molecules as anti-cancer agents against Tousled-like kinases (TLKs). We show that compound 2 composed of an indirubin-3′-oxime group linked with a (N-methylpiperidin-2-yl)ethyl moiety possessed inhibitory activity toward both TLK1 and TLK2 in vitro and diminished the phosphorylation level of the downstream substrate anti-silencing

Mutations in Fms-like tyrosine kinase 3 (FLT3) have been implicated in the pathogenesis of acutemyeloidleukemia (AML) by affecting the proliferation and differentiation of hematopoietic stem and progenitor cells. Although several FLT3 inhibitors have been developed, the occurrence of secondary TKD mutations of FLT3 such FLT3/D835Y and FLT3/F691L lead to drug resistance and has become a key area of
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
