From nature to nanoscale: advances, challenges, and preclinical translation of nanofiber drug delivery systems containing plant‐derived active ingredients

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Since the early 1960s, nanotechnology has been a critical area of science, allowing for the development of sophisticated nanomaterials. Nanofibers, one of the most widely used nanotechnological drug delivery systems, have emerged as a highly versatile platform within modern pharmaceutical sciences.

Nanoliposome-Mediated Delivery of Lipophilic Antioxidants as a Strategy to Improve the Preservation Capacity of Pig Semen at 17°C. [PDF]

Reprod Domest Anim
ABSTRACT While lipophilic antioxidants such as flavonols may improve the preservation capacity of sperm at 17°C, their low stability and bioavailability can reduce their biological effectiveness. Encapsulation strategies have been proposed to improve the delivery and cellular availability of hydrophobic antioxidants.

Polyphenol dietary supplementation prevents inflammation‐induced muscle atrophy in a zebrafish (Danio rerio) model

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Diet‐induced inflammation is a major cause of muscle degeneration impacting human and animal health. Owing to their anti‐inflammatory and antioxidant properties, polyphenols have attracted considerable interest as feed additives.

Phenolic profile of selected grape (Vitis vinifera L.) varieties in the course of ripening and Botrytis cinerea infections

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Grapevine phenolic compounds play key roles in plant defense and wine quality. Composition depends on factors such as maturity and infections such as grey mold caused by Botrytis cinerea. Grapevines respond to infections by actively modifying their phenolic profile.

Synthesis of novel fluorinated flavonols via Algar-Flynn-Oyamada reaction

Vietnam Journal of Science, Technology and Engineering
Flavonols have attracted considerable attention due to their diverse biological effects. However, naturally occurring flavonols are typically present only in low concentrations, with fluorine-containing flavonols being especially rare.

The efficiency of flavonols in the setting of experimentally induced allergic asthma

Revista Alergia México, 2018
Objective: Our objective in this study was to evaluate and compare the therapeutic potency (bronchodilation, action on ciliary beat frequency, anti-inflammatory, anti-remodelling effect) of a different flavonol derivates: quercetin, fisetin and morin in ...

Modulation of Phytohormone Signaling: A Primary Function of Flavonoids in Plant–Environment Interactions

Frontiers in Plant Science, 2018
The old observation that plants preferentially synthesize flavonoids with respect to the wide range of phenylpropanoid structures when exposed to high doses of UV-B radiation has supported the view that flavonoids are primarily involved in absorbing the ...

Use of predictive tools for the analysis of bioactive compounds in Crocus sativus L. flowers

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Crocus sativus L. (saffron) flowers have high bioactive potential because of their content of crocins, safranal and phenolic compounds. The development of predictive models based on near‐infrared (NIR) spectroscopy and partial least squares regression to estimate the antioxidant capacity of saffron flower, evaluated using oxygen ...

Synthesis of a library of glycosylated flavonols

Tetrahedron Letters, 2008
Flavonols are an important class of natural products isolated from plants. Some glycosylated flavonols showed very interesting biological activities. A library of flavonols has been made through Algar-Flynn-Oyamada reaction from 2'-hydroxyacetophenones and benzaldehydes. Glycosylation of these flavonols with various glycosyl donors affords a library of
