A–C Estrogens as Potent and Selective Estrogen Receptor-Beta Agonists (SERBAs) to Enhance Memory Consolidation under Low-Estrogen Conditions [PDF]

open access: yes, 2018
Estrogen receptor-beta (ERβ) is a drug target for memory consolidation in postmenopausal women. Herein is reported a series of potent and selective ERβ agonists (SERBAs) with in vivo efficacy that are A–C estrogens, lacking the B and D estrogen rings ...

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 ...

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

open access: yesAdvanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Finding Characteristic Substructures for Metabolite Classes [PDF]

open access: yes, 2012
We introduce a method for finding a characteristic substructure for a set of molecular structures. Different from common approaches, such as computing the maximum common subgraph, the resulting substructure does not have to be contained in its exact form

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.

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.

In Vitro Evaluation of Antileishmanial Activity of Commiphora myrrha Essential Oil Nanoliposome

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study investigates the efficacy of nanoliposomal formulations containing myrrh essential oil in combating Leishmania protozoa in laboratory settings. Myrrh essential oil and nanoliposomes were prepared in RPMI‐1640 medium at concentrations of 1, 2, 5 and 10 µg/dL.
