Five new sesquiterpenes, neurolobatin A (1), neurolobatin B (2), 5β-hydroxy-8β-isovaleroyloxy-9α-hydroxycalyculatolide (3), 3-epi-desacetylisovaleroylheliangine (4), and 3β-acetoxy-8β-isovaleroyloxyreynosin (5), were isolated from the aerial parts of Neurolaena lobata. The structures were

Two Brazilian species of Dimerostemma (Asteraceae) were chemically investigated. Two known sesquiterpene lactones (STLs), a germacrolide and an eudesmanolide, were isolated from D. episcopale while D. brasilianum afforded the new germacranolide

In addition to known heliangolides, a new eudesmanolide was isolated from the leaf rinse extract of Viguiera robusta (Asteraceae). Structural elucidation was based on spectral analysis. It is the first report on eudesmanolides in members of the subgenus Calanticaria of Viguiera. In this work, the

Wedelia (Sphagneticola trilobata, Syn. Wedelia trilobata), a notoriously invasive agricultural weed, can inhibit the growth and development of crops in the field. Eight new eudesmanolides (1-8), along with twelve known congeners (9-20), were isolated and identified from the flowers of Wedelia. Their

Two new eudesmane-type sesquiterpene lactones were isolated from the roots of Inula racemosa and their structures were elucidated as 3β-hydroxy-11α,13-dihydroalantolactone (1) and 11α-hydroxy-eudesm-5-en-8β,12-olide (2). Their cytotoxic activities against five human cancer cell lines had been tested

The phytochemical study of the aerial parts of Melampodium perfoliatum afforded six melampolides (1, 3, 5-8), a eudesmanolide (9), two diterpene lactones (10, 11), and two ent-kaurane derivatives (12, 13), together with the known melampodin (2) and polymatin A (4). The structures of the compounds

Sesquiterpene lactones (SLs) are natural products responsible for the anti-inflammatory activity of a variety of medicinal plants, mainly from the Asteraceae family. Here, we investigated whether they also influence the process of exocytosis of pro-inflammatory enzymes, such as the human neutrophil

Seven previously undescribed sesquiterpene lactones, three known sesquiterpene lactones (ixerin D, 15-p-hydroxyphenylacetyllactucin, and 15-p-hydroxyphenylacetyllactucin-8-sulfate), and two known quinic acid derivatives (3-O-feruloylquinic acid and 3,5-di-O-caffeoylquinic acid) were isolated from

In recent years, a growing interest has developed in the field of biological activity of plant metabolites. Research in this area considering antimicrobial, antioxidant, cytotoxic, anti-inflammatory, and other properties, is currently expanding, reporting various species to possess such biological

The genus Carpesium plants contain many kinds of sesquiterpenes. Up to now, more than 201 sesquiterpene compounds have been isolated and identified, including 86 germacranolides, 30 eudesmanolides, 29 guaianolides, 23 sesquiterpene dimers, 9 pseudoguaianes, 9 carabranolides, 7 xanthanolides, 6

The potential inhibitory effect of 54 Mexican Indian medicinal plants on the activation of transcription factor NF-kappaB was studied. Band-shift experiments identified the ethanolic leaf extracts of Artemisia ludoviciana ssp. mexicana, Calea zacatechichi, and Polymnia maculata (all rich in

Sesquiterpene lactones (SLs) are the active compounds of a variety of traditionally used medicinal plants from the Asteraceae family. They are known to possess a considerable antiinflammatory activity in different inflammation models. They inhibit the transcription factor NF-kappaB probably by

Sesquiterpene lactones are a large group of natural compounds, found primarily in plants of Asteraceae family, with over 5000 structures reported to date. Within this family, genus Artemisia is very well represented, having approximately 500 species characterized by the presence of eudesmanolides
