Effects of catechins, resveratrol, silymarin components and some of their conjugates on xanthine oxidase‐catalyzed xanthine and 6‐mercaptopurine oxidation

open access: yesJournal of the Science of Food and Agriculture, Volume 105, Issue 5, Page 2765-2776, 30 March 2025.
Abstract BACKGROUND Over the past two decades, the global incidence of gout has markedly increased, affecting people worldwide. Considering the side effects of xanthine oxidase (XO) inhibitor drugs (e.g. allopurinol and febuxostat) used in the treatment of hyperuricemia and gout, the potential application of phytochemicals has been widely studied.

Enteric helminths promote Salmonella co-infection by altering the intestinal metabolome [PDF]

open access: yes, 2017
Intestinal helminth infections occur pre dominantly in regions where exposure to enteric bacterial pathogens is also common. Helminth infections inhibit host immunity against microbial pathogens, which has largely been attributed to the induction of ...

Antifeedant Activity of Benzopyrans from Melicope latifolia [PDF]

open access: yes, 2020
Two benzopyrans, evodionol (1), and evodion (2) were isolated from the stem bark of Melicope latifolia. The structure of both compounds was identified based on 1D and 2D NMR, UV, and IR spectroscopy.

Thermally Bistable Stiff Stilbene Photoswitches and Polymer Applications

open access: yesThe Chemical Record, EarlyView.
Thermally stable photoswitches offer new opportunities for controlling polymer structures and functions under nonequilibrium conditions. This Personal Account highlights stiff stilbene (SS) and sterically hindered stiff stilbene (HSS) photoswitches, which combine large structural changes with exceptional thermal bistability.
