Subtly Modulating Glycogen Synthase Kinase 3 β: Allosteric Inhibitor Development and Their Potential for the Treatment of Chronic Diseases
摘要:
Glycogen synthase kinase 3 beta (GSK-3 beta) is a central target in several unmet diseases. To increase the specificity of GSK-3 beta inhibitors in chronic treatments, we developed small molecules allowing subtle modulation of GSK-3 beta activity. Design synthesis, structure activity relationships, and binding mode of quinoline-3-carbohydrazide derivatives as allosteric modulators of GSK-3 beta are presented here. Furthermore, we show how allosteric binders may overcome the beta-catenin side effects associated with strong GSK-3 beta inhibition. The therapeutic potential of some of these modulators has been tested in human samples from patients with congenital myotonic dystrophy type 1 (CDM1) and spinal it atrophy (SMA) patients. We found that compound 53 improves delayed myogenesis in CDM1 myoblasts, while compounds 1 and 53 have neuroprotective properties in SMA-derived cells. These findings suggest that the allosteric modulators of GSK-3 beta may be used for future development of drugs for DM1, SMA, and other chronic diseases where GSK-3 beta inhibition exhibits therapeutic effects.

A library of 1,4-benzodiazepines has been synthesised and evaluated for activity against Trypanosoma brucei, a causative parasite of Human African Trypanosomiasis (HAT). The most potent of these derivatives has an MIC value of 0.97 μM. Herein we report the design, synthesis and biological evaluation of the abovementioned compounds.

The present invention relates to heterocyclic substituted quinoline derivatives as allosteric inhibitors of the glycogen synthase kinase-3 (GSK-3) enzyme. Therefore, these compounds are useful for the manufacturing of a medicament designed for the treatment and/or prevention of diseases wherein GSK-3 is involved, such as neurodegenerative diseases, inflammatory diseases, cancer, diabetes, and to promote various regenerative processes.

[4 + 2]-Annulation of Prop-2-ynylsulfonium Salts and Isatoic Anhydrides: Access to 3-Methylthio-4-quinolones
An unparalleled [4 + 2]-annulation of prop-2-ynylsulfonium salts with isatoicanhydrides was developed, affording a series of 4-quinolones with a alkylthio group in medium to good yields under mild conditions. In this reaction type, the prop-2-ynylsulfonium salt serves as a C2 synthon and sulfide does not act as a leaving group, providing facile access to organosulfur compounds. The resulting quinolone
