Triazole-Based Inhibitors of the Wnt/β-Catenin Signaling Pathway Improve Glucose and Lipid Metabolisms in Diet-Induced Obese Mice

Wnt/β-catenin signaling pathway is implicated in the etiology and progression of metabolic disorders. Although lines of genetic evidence suggest that blockage of this pathway yields favorable outcomes in treating such ailments, few inhibitors have been used to validate the promising genetic findings. Here, we synthesized and characterized a novel class of triazole-based Wnt/β-catenin signaling inhibitors and assessed their effects on energy metabolism. One of the top inhibitors, compound 3a, promoted Axin stabilization, which led to the proteasome degradation of β-catenin and subsequent inhibition of the Wnt/β-catenin signaling in cells. Treatment of hepatocytes and high fat diet-fed mice with compound 3a resulted in significantly decreased hepatic lipid accumulation. Moreover, compound 3a improved glucose tolerance of high fat diet-fed mice without noticeable toxicity, while downregulating the genes involved in the glucose and fatty acid anabolisms. The new inhibitors are expected to be further developed for the treatment of metabolic disorders.

Syntheses and biological evaluation of 1,2,3-triazole and 1,3,4-oxadiazole derivatives of imatinib

Three novel series of 1,2,3-triazole and 1,3,4-oxadiazole derivatives of imatinib were prepared and evaluated in vitro for their cytostatic effects against a human chronic myeloid leukemia (K562), acute myeloid leukemia (HL60), and human leukemia stem-like cell line (KG1a). The structure-activity relationship was analyzed by determining the inhibitory rate of each imatinib analog. Benzene and piperazine rings were necessary groups in these compounds for maintaining inhibitory activities against the K562 and HL60 cell lines. Introducing a trifluoromethyl group significantly enhanced the potency of the compounds against these two cell lines. Surprisingly, some compounds showed significant inhibitory activities against KG1a cells without inhibiting common leukemia cell lines (K562 and HL60). These findings suggest that these compounds are able to inhibit leukemia stem-like cells.

Probing the reactivity of o-phthalaldehydic acid/methyl ester: Synthesis of N-isoindolinones and 3-arylaminophthalides

A new method for the synthesis of N-substituted isoindolinones and 3-arylaminophthalides was developed through aza-Wittig/cyclisation. The reaction of o-phthalaldehydic acid methyl ester with benzylic, aromatic and aliphatic azides gave N-isoindolinones w
