New 9,10-secosteroids from biotransformations of bile acids with Rhodococcus ruber

open access: yes, 2013
The biotransformations of cholic, deoxycholic and hyocholic acids with Rhodococcus ruber are reported. In all biotransformations the C17-side chain is partially degraded and the new 9,10-secosteroids 4a (54%) and 4b (55%), are obtained from cholic and ...

Biochemical and Molecular Insights Into Monocrotaline‐Induced Hepatotoxicity: An Experimental Mouse Study

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Monocrotaline (MCT), a plant‐derived pyrrolizidine alkaloid, is well known for its hepatotoxic effects. However, full elucidation of the mechanisms underlying MCT‐induced hepatotoxicity, as well as the development of reliable biomarkers for early detection and monitoring, requires an integrated evaluation of biochemical, molecular, and ...

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.

Mycotoxin management in the cereal supply chain: Advanced detection, detoxification, and smart packaging strategies

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Mycotoxins remain a persistent threat to the safety and quality of cereal grains and other agricultural products, and their impact on human health continues to raise global concerns. In many situations, the practices traditionally used to control these toxins are no longer sufficiently effective. They can be costly, difficult to implement on a

Essential oils as bioherbicides: effects of orange and citronella oils on weed germination and early growth

open access: yesPest Management Science, EarlyView.
Essential oils from orange and citronella showed dose‐dependent inhibition of weed germination and early growth, highlighting their potential as bioherbicides and sustainable tools for integrated weed management. Abstract BACKGROUND Increasing selection of herbicide‐resistant weed biotypes has intensified the search for alternatives to the intensive ...

A new cyclohexyl-based chiral auxiliary: application in the total synthesis of (+)-linalool oxide

open access: yes, 2010
Seven different racemic cyclohexyl-based chiral auxiliaries (2.4-2.10) were synthesised in moderate to good yields (38-85%) by nucleophilic opening of cyclohexene oxide using carbanions.

Microbiome‐mediated chemical communication in insects: Implications for pest management

open access: yesPest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Phenolic Biotransformations during Conversion of Ferulic Acid to Vanillin by Lactic Acid Bacteria

open access: yes, 2020
Vanillin is widely used as food additive and as a masking agent in various pharmaceutical formulations. Ferulic acid is an important precursor of vanillin that is available in abundance in cell walls of cereals like wheat, corn, and rice.
