Structural Basis for the Synthesis of Indirubins as Potent and Selective Inhibitors of Glycogen Synthase Kinase-3 and Cyclin-Dependent Kinases
摘要:
Pharmacological inhibitors of glycogen synthase kinase-3 (GSK-3) and cyclin-dependent kinases have a promising potential for applications against several neurodegenerative diseases such as Alzheimer's disease. Indirubins, a family of bis-indoles isolated from various natural sources, are potent inhibitors of several kinases, including GSK-3. Using the cocrystal structures of various indirubins with GSK-3beta, CDK2 and CDK5/p25, we have modeled the binding of indirubins within the ATP-binding pocket of these kinases. This modeling approach provided some insight into the molecular basis of indirubins' action and selectivity and allowed us to forecast some improvements of this family of bis-indoles as kinase inhibitors. Predicted molecules, including 6-substituted and 5,6-disubstituted indirubins, were synthesized and evaluated as CDK and GSK-3 inhibitors. Control, kinase-inactive indirubins were obtained by introduction of a methyl substitution on N1.

A simple and convenient route for synthesis of a series of 4- or 6-substituted indirubin derivatives by oxidation and subsequent condensation of indoxyl and isatin is described. Acidic reaction conditions are crucial to the condensation of 4-substitutedderivatives, whereas for the condensation of 6-substituted derivatives, both acidic and basic conditions work well.

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

Design, Synthesis, and Biological Evaluation for First GPX4 and CDK Dual Inhibitors
death has great advantages in the treatment of cancers. A series of glutathione peroxidase 4 (GPX4) and cyclin-dependentkinase (CDK) dual inhibitors were designed and synthesized, given the synergistic anticancer effect of ML162 (GPX4 inhibitor) in combination with indirubin-3′-oxime (IO) (CDKinhibitor). Compound B9 exhibited the highest potential cytotoxic activity against all four cell lines and displayed
