Discovery of a potent anticancer agent against pancreatic ductal adenocarcinoma targeting FAK with DFG-out state and JAK/Aurora kinases.

Pancreatic ductal adenocarcinoma (PDAC) is a clinically challenging cancer because of the difficulty in diagnosis and its resistance to chemotherapy. Focal adhesion kinase (FAK) is found overexpressed in PDAC, and targeting FAK has been proved to impede the progress of PDAC. However, most of FAK inhibitors were reported to bind with FAK in a DFG-in conformation, leading to a limited anti-tumor effect in clinical studies.

Enhanced In Vitro Efficacy of Verbascoside in Suppressing Hepatic Stellate Cell Activation via ROS Scavenging with Reverse Microemulsion.

The Discovery of Indole-2-carboxylic Acid Derivatives as Novel HIV-1 Integrase Strand Transfer Inhibitors.

As an important antiviral target, HIV-1 integrase plays a key role in the viral life cycle, and five integrase strand transfer inhibitors (INSTIs) have been approved for the treatment of HIV-1 infections so far. However, similar to other clinically used antiviral drugs, resistance-causing mutations have appeared, which have impaired the efficacy of INSTIs. In the current study, to identify novel integrase inhibitors, a set of molecular docking-based virtual screenings were performed, and indole-2-carboxylic acid was developed as a potent INSTI scaffold.

Amelioration effects of α-viniferin on hyperuricemia and hyperuricemia-induced kidney injury in mice.

Background: α-Viniferin, the major constituent of the roots of Caragana sinica (Buc'hoz) Rehder with a trimeric resveratrol oligostilbenoid skeleton, was demonstrated to possess a strong inhibitory effect on xanthine oxidase in vitro, suggesting it to be a potential anti-hyperuricemia agent. However, the in vivo anti-hyperuricemia effect and its underlying mechanism were still unknown.

Purpose: The current study aimed to evaluate the anti-hyperuricemia effect of α-viniferin in a mouse model and to assess its safety profile with emphasis on its protective effect on hyperuricemia-induced renal injury.

Design, synthesis and bioevaluation of 1,2,4-thiadiazolidine-3,5-dione derivatives as potential GSK-3β inhibitors for the treatment of Alzheimer's disease.

Tideglusib is a non-competitive GSK-3β inhibitor which contain 1,2,4-thiadiazolidine-3,5-dione moiety, and now mainly used for progressive supranuclear palsy due to the lack of some primary cognitive endpoints and secondary endpoints in a phase IIb trail for Alzheimer's disease. Additionally, insufficient evidence exists to support that there are obvious covalent bonds between Tideglusib and GSK-3β. Targeted covalent inhibition strategy could improve the binding efficiency, selectivity and duration of kinase inhibitors.

Design, synthesis, and in vitro protective effect evaluation of α-carboline derivatives against HO-induced cardiomyocyte injury.

As one of the most important features of myocardial ischemia reperfusion (MI/R) injury, the overproduction of reactive oxygen species (ROS) overwhelms the intrinsic antioxidant and impairs the function of mitochondria and, finally, leads to cardiomyocyte death. To improve the damage of cardiomyocyte caused by oxidative stress, a series of α-carboline derivatives were designed and synthesized in this study. The biological studies revealed that most of the α-carbolines exhibited obvious protective activities against HO-induced cardiomyocyte injury.
