Promising Inhibitory Effects of Anthraquinones, Naphthopyrone, and Naphthalene Glycosides, from Cassia obtusifolia on α-Glucosidase and Human Protein Tyrosine Phosphatases 1B

Molecules, 2016
The present work aims to evaluate the anti-diabetic potentials of 16 anthraquinones, two naphthopyrone glycosides, and one naphthalene glycoside from Cassia obtusifolia via inhibition against the protein tyrosine phosphatases 1B (PTP1B) and α-glucosidase.

Anti-human cytomegalovirus activity and toxicity of sulfonated anthraquinones and anthraquinone derivatives

Antiviral Research, 1995
Sulfonated anthraquinones and other anthraquinone derivatives were evaluated for anti-human cytomegalovirus (HCMV) activity, cytotoxicity and genotoxicity. Acid blues 40 and 129, acid black 48, alizarin violet R and reactive blue 2 were the most active compounds having selective indices of greater than 30 and EC50 values of 4-30 microM.

Addressing Inherent Challenges to Chemical Relithiation of Cycled End‐of‐Life Cathode Materials

Advanced Energy Materials, EarlyView.
The evolution of fluorine surface species is tracked during a low‐temperature redox mediator relithiation process for direct recycling of cycled NMC 622. A washing step is presented as a solution for mediating adverse effects of surface contamination. Redox mediator relithiation is shown to be a rapid, efficient method that can be applied to cycled NMC
