Enhancing polyphenol synthesis and antioxidant activity in Camellia sinensis using shikimic and salicylic acids

open access: yesJSFA reports, EarlyView.
Abstract Background Camellia sinensis, widely consumed as tea, is the second most popular beverage globally and is valued for its health benefits. However, environmental stressors pose a significant challenge to the tea industry. This study investigates the potential of shikimic acid (ShA) and its derivative, salicylic acid (SA), as inducers to enhance

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.

Identification of distant drug off-targets by direct superposition of binding pocket surfaces. [PDF]

open access: yes, 2013
Correctly predicting off-targets for a given molecular structure, which would have the ability to bind a large range of ligands, is both particularly difficult and important if they share no significant sequence or fold similarity with the respective ...

Microwave‐Assisted Organic Syntheses in Deep Eutectic Solvents: A Win‐Win Association for Sustainable Chemistry

open access: yesChemistryOpen, EarlyView.
In organic synthesis, deep eutectic solvents (DES) have demonstrated their ability to be used as reaction media for the development of reactions in line with green chemistry principles. This review presents an overview of microwave‐assisted organic synthesis in DES, highlighting the diversity of uses for these solvents, their role in mechanisms, the ...

Asymmetric Synthesis of Spirocyclic 2-Benzopyrans for Positron Emission Tomography of σ1 Receptors in the Brain

open access: yesPharmaceuticals, 2014
Sharpless asymmetric dihydroxylation of styrene derivative 6 afforded chiral triols (R)-7 and (S)-7, which were cyclized with tosyl chloride in the presence of Bu2SnO to provide 2-benzopyrans (R)-4 and (S)-4 with high regioselectivity.

A facile and one-pot synthesis of new tetrahydrobenzo[b]pyrans in water under microwave irradiation

open access: yesBMC Chemistry, 2019
Eleven new tetrahydrobenzo[b]pyran derivatives were synthesized via a three component reaction of different aromatic aldehydes, methyl cyanoacetate and 1,3-cyclohexadione, with water as solvent under catalyst-free microwave irradiation. The structures of

Benzo-pyrones for reducing and controlling lymphoedema of the limbs. [PDF]

open access: yes, 2009
Background Lymphoedema is the accumulation of excess fluid in the body caused by obstruction of the lymphatic drainage mechanisms. Treatment with Benzo-pyrones is thought to reduce fluid forming in the subcutaneous tissues and reduce pain and discomfort ...

Microbial Contributions to Primate Reproduction

open access: yesEvolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 1, March 2026.
ABSTRACT Reproduction is a complex process, and microbes play a far greater role than previously imagined. This review explores the ways that microbiomes influence the rich tapestry of reproductive processes and outcomes within the primate lineage, including pre‐copulatory and post‐copulatory mechanisms.
