Phenolamides: Bridging polyamines to the phenolic metabolism
2010年11月1日 · Phenolamides constitute a diverse and quantitatively major group of secondary metabolites resulting from the conjugation of a phenolic moiety with polyamines or with deaminated aromatic aminoacids. This review summarizes their bioactivities and their reported roles in plant development, adaptation and defence compared to those of their ...
Phenolic amides (avenanthramides) in oats – an update review
2024年1月23日 · Compared to the other cereals, oats contain a unique group of phenolic alkaloids known as avenanthramides (AVNs). Structural analysis showed that AVNs are conjugates of one of three phenylpropanoids (p- coumaric, ferulic, or caffeic acids) and anthranilic acid (or a hydroxylated and/or methoxylated derivative of anthranilic acid) ( ).
Amides From Plants: Structures and Biological Importance
2018年1月1日 · Isobutyl amine, phenylethyl amine, piperidine, pyrrolidine, putrescine, spermidine, and tryptamine are the predominant amine components of natural amides, which are mainly distributed in Piperaceae and Rutaceae families. Several sulfur-containing amides are also described which have been found to show antifungal and insecticidal activities.
Phenolic amides (avenanthramides) in oats - an update review
Avenanthramides (AVNs), the unique plant alkaloids of secondary metabolites found in oats, are nutritionally important for humans and animals. Numerous bioactivities of AVNs have been investigated and demonstrated in vivo and in vitro. Despite all these, researchers from all over the world are taking efforts to learn more knowledge about AVNs.
Phenolamides: Plant specialized metabolites with a wide range …
2020年11月1日 · Phenolamides result from the association of phenolic acids with aliphatic or aromatic amines. This structurally diverse family is largely distributed in medicinal and dietary plants. They exhibit antimicrobial, antioxidant, anti-inflammatory and anticancer activities.
Facile Amidation of Non-Protected Hydroxycinnamic Acids for the ...
2022年3月28日 · The result is a protocol for straightforward one-pot synthesis of phenol amides at room temperature within 25 h using equimolar amounts of N,N′-dicyclohexylcarbodiimide (DCC), amine, hydroxycinnamic acid, and sodium bicarbonate in aqueous acetone. Eight structurally diverse phenol amides were synthesized and fully chemically characterized.
Structurally Diverse Phenolic Amides from the Fruits of
2023年7月18日 · A total of nine new phenolic amides (1-9), including four pairs of enantiomeric mixtures (3-5 and 8), along with ten known analogues (10-19) were identified from the fruits of Lycium barbarum using bioassay-guided chromatographic fractionation. Their structures were elucidated by comprehensive spectroscopic and spectrometric analyses, chiral ...
Phenolic Phytochemicals: Sources, Biosynthesis, Extraction, and …
2019年7月28日 · Phenolic compounds are among the major group of phytochemicals that are extremely diverse in nature, ranging from flavonoids to polyphenolic amides. They are available in almost every plant part; however, their bioavailability differs from one plant to another.
Phenolamides in plants: an update on their function, regulation, …
2020年12月14日 · Phenolamides arise from phenolic moieties (mainly hydroxycinnamic acids and derivatives) covalently linked through amide bonds to an aromatic monoamine or an aliphatic polyamine (e.g. tyramine, agmatine, anthranilate, or spermidine). Therefore, these phenolic compounds can be considered alkaloids.
Phenolamides in plants: an update on their function, regulation, …
2021年3月29日 · Since the discovery of the first phenolamide in the late 1940s, decades of phytochemical analyses have revealed a high structural diversity for this family and a wide distribution in the plant kingdom.
