germacranolide/inflammation

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

Sigesbeckia orientalis, more commonly referred to as Herba Sigesbeckiae or Xi Xian Cao in traditional Chinese medicine and hy thiêm in traditional Vietnamese medicine, is used in China and Vietnam to treat inflammatory diseases such as arthritis, rheumatism, and joint pain. In initial

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

Background The medicinal properties of Inula cappa, a perennial shrub, are ascribed to its roots. In this article, we study the anti-inflammatory and immunomodulatory activities of I. cappa root extracts based on its utilization in traditional medicine-treatment of rheumatoid arthritis, menoxenia,

Many sesquiterpene lactones (Sls) are known to possess anti-inflammatory activities. To gain further insight into their structure-activity relationships and the molecular mechanism of action, four germacranolide sesquiterpene lactones which differ in the skeleton and the number of reactive centers

BACKGROUND The t(2;5)(p23;q35) chromosomal translocation results in the expression of the fusion protein NPM/ALK that when expressed in T-lymphocytes gives rise to anaplastic large cell lymphomas (ALCL). In search of new therapy options the dichloromethane extract of the ethnomedicinal plant

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

Background: Enhydra fluctuans Lour, a tropical herb, commonly known as helencha or harkuch, belonging to family Asteraceae, and is an edible semi-aquatic herbaceous vegetable plant with serrate leaves, grows commonly in different parts of

BACKGROUND Arctotis arctotoides (Asteraceae) is part of the genus Arctotis. Arctotis is an African genus of approximately 70 species that occur widely in the African continent with diverse medicinal values. This plant is used for the treatment of indigestion and catarrh of the stomach, epilepsy,

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

Sesquiterpene lactones (SLs) constitute a large and diverse group of biologically active plant compounds that possess anti-inflammatory and antitumor activity. The subclass germacranolides is one of the major groups of SLs. It includes parthenolide, a highly cytotoxic SL that is being tested in

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
