Antiviral Activity of Carrageenans and Processing Implications

Marine Drugs, Год журнала: 2021, Номер 19(8), С. 437 - 437

Опубликована: Июль 30, 2021

Carrageenan and carrageenan oligosaccharides are red seaweed sulfated carbohydrates with well-known antiviral properties, mainly through the blocking of viral attachment stage. They also exhibit other interesting biological properties can be used to prepare different drug delivery systems for controlled administration. The most active forms λ-, ι-, κ-carrageenans, degree sulfation position being determined in their properties. obtained from sustainable worldwide available resources influence manufacturing on composition, structure, should considered. This review presents a survey relation processing conditions, particularly those assisted by intensification technologies during extraction stage, discusses possibility further chemical modifications.

Reactive Oxygen Species as a Link between Antioxidant Pathways and Autophagy

Oxidative Medicine and Cellular Longevity, Год журнала: 2021, Номер 2021(1)

Опубликована: Янв. 1, 2021

Reactive oxygen species (ROS) are highly reactive molecules that can oxidize proteins, lipids, and DNA. Under physiological conditions, ROS mainly generated in the mitochondria during aerobic metabolism. pathological excessive disrupt cellular homeostasis. High levels of result severe oxidative damage to machinery. However, a low/mild level could serve as signal trigger cell survival mechanisms. To prevent cope with biomolecules, cells have developed various antioxidant detoxifying Meanwhile, initiate autophagy, process self-clearance, which helps reduce by engulfing degrading oxidized substance. This review summarizes interactions among ROS, pathways. The effects natural phytochemicals on autophagy induction, antioxidation, dual-function also discussed.

Prevention and Treatment of Cardiovascular Diseases with Plant Phytochemicals: A Review

Evidence-based Complementary and Alternative Medicine, Год журнала: 2022, Номер 2022, С. 1 - 21

Опубликована: Июль 4, 2022

Cardiovascular diseases (CVDs) are the world's leading killers, accounting for 30% deaths. According to WHO report, CVDs kill 17.9 million people per year, and there will be 22.2 deaths from CVD in 2030. The death rates rise as get older. Regarding gender, rate of women by (51%) is higher than that men (42%). To decrease prevent CVD, most rely on traditional medicine originating plant (phytochemicals) addition or preference commercially available drugs recover their illness. therapy efficacy 92 plants, including 15 terrestrial examined.

Hydroxylation decoration patterns of flavonoids in horticultural crops: chemistry, bioactivity, and biosynthesis

Horticulture Research, Год журнала: 2022, Номер 9

Опубликована: Янв. 1, 2022

Abstract Flavonoids are the most widespread polyphenolic compounds and important dietary constituents present in horticultural crops such as fruits, vegetables, tea. Natural flavonoids responsible for quality traits, food colors beneficial antioxidants, numerous investigations have shown that intake of can reduce incidence various non-communicable diseases. Analysis thousands reported so far has different hydroxylation modifications affect their chemical properties nutritional values. These diverse be classified based on patterns B, C, A rings multiple structure–activity analyses decoration at specific positions markedly enhances bioactivities. This review focuses current knowledge concerning catalyzed by several types hydroxylase enzymes. Flavonoid 3′-hydroxylase (F3′H) flavonoid 3′5′-hydroxylase (F3′5′H) enzymes B ring flavonoids. Flavanone 3-hydroxylase (F3H) is key C ring, while flavone 6-hydroxylase (F6H) 8-hydroxylase (F8H) ring. hydroxylases biosynthesis pathway promising targets future bioengineering plants mass production with designated high importance. In addition, places may help render ready degradation, catabolic turnover open door new lines inquiry.

Root metabolome of plant–arbuscular mycorrhizal symbiosis mirrors the mutualistic or parasitic mycorrhizal phenotype

New Phytologist, Год журнала: 2022, Номер 234(2), С. 672 - 687

Опубликована: Янв. 28, 2022

The symbiosis of arbuscular mycorrhizal fungi (AMF) with plants, the most ancient and widespread association, exhibits phenotypes that range from mutualism to parasitism. However, we still lack an understanding cellular-level mechanisms differentiate regulate these phenotypes. We assessed modulation in growth parameters root metabolome two sorghum accessions inoculated AMF species (Rhizophagus irregularis, Gigaspora gigantea), alone a mixture under phosphorus (P) limiting conditions. Rhizophagus irregularis exhibited mutualistic phenotype increased P uptake plant growth. This positive outcome was associated facilitatory metabolic response including higher abundance organic acids specialized metabolites critical maintaining functional symbiosis. G. gigantea parasitic led depression resulted inhibitory responses p-hydroxyphenylacetaldoxime antifungal properties. These findings suggest differential plant-AMF could be regulated by or reflected changes arises interaction specific species. A symbiotic association prevailed when host plants were exposed AMF. Our results provide metabolome-level landscape highlight importance identity both crop genotypes facilitating

Evolution and function of red pigmentation in land plants

Annals of Botany, Год журнала: 2022, Номер 130(5), С. 613 - 636

Опубликована: Сен. 7, 2022

Abstract Background Land plants commonly produce red pigmentation as a response to environmental stressors, both abiotic and biotic. The type of pigment produced varies among different land plant lineages. In the majority species they are flavonoids, large branch phenylpropanoid pathway. Flavonoids that can confer colours include 3-hydroxyanthocyanins, 3-deoxyanthocyanins, sphagnorubins auronidins, which predominant pigments in flowering plants, ferns, mosses liverworts, respectively. However, some have lost capacity for anthocyanin biosynthesis nitrogen-containing betalain instead. Some terrestrial algal also an stress response, these carotenoid phenolic pigments. Scope this review, we examine: triggers induce non-reproductive tissues; theories on functions stress-induced pigmentation; evolution biosynthetic pathways; structure–function aspects types. We compare data with those algae, discuss possible explanations lack hornwort lineage plants. Conclusions evidence suggests pathways evolved numerous times provide compounds colour screen damaging photosynthetically active radiation but secondary specific benefits particular lineage.

Flavonoids are a biochemically diverse group of specialized metabolites in plants that derived from phenylalanine. While the biosynthesis flavonoid aglycone is highly conserved across species and well characterized, numerous species-specific decoration steps their relevance remained largely unexplored. The takes place at cytosolic side endoplasmatic reticulum (ER), but accumulation various flavonoids was observed central vacuole. A universal explanation for subcellular transport has eluded researchers decades. Current knowledge suggests glutathione S-transferase-like protein (ligandin) protects anthocyanins potentially proanthocyanidin precursors during to ABCC transporters lower extend MATE sequester into Glycosides specific sequestered through transporters. P-ATPase tonoplast other proteins generate proton gradient required MATE-mediated antiport. Vesicle-mediated ER vacuole considered as an alternative or additional route.
