OBJECTIVE
To evaluate the anti-inflammatory activity of methyl ferulate (MF) isolated from the roots of Stemona tuberosa (S. tuberosa) Lour (Stemonaceae) in lipopolysaccharide activated macrophage cells.
METHODS
Methanol extracts of a root powder of S. tuberosa were prepared for isolation of a
OBJECTIVE
Our previous study demonstrated that a Stemona tuberosa extract had significant effects on cigarette smoking (CS)-induced lung inflammation in mice. The present study evaluated the potential of tuberostemonine N (T.N) to prevent airway inflammation and suppress airway responses in a
Chronic obstructive pulmonary disease (COPD) is mainly caused by cigarette smoking and is characterized by the destruction of lung parenchyma, structural alterations of the small airways, and systemic inflammation. Tuberostemonine (TS) is an alkaloid-type phytochemical from Stemona tuberosa. In the
Two polyketides, stemonones A (1) and B (2) with new skeletons, were isolated from the roots of Stemona tuberosa. Their absolute structures were fully characterized by comprehensive spectroscopic analyses and comparison of experimental electronic circular dichroism (ECD) spectra with calculated
BACKGROUND
Stemona tuberosa (ST) is a traditional herbal medicine used for the treatment of various respiratory diseases in eastern Asia.
OBJECTIVE
We investigated the anti-inflammatory effects of a ST water extract in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages and in cigarette smoke
Ethnopharmacological relevance: Plants of genus Stemona (Stemonaceae) have long been used locally and traditionally in many South and East Asia counties to relieve cough, dispel phlegm, prevent asthma, control pests, diminish inflammation
Osteoporosis has been attributed to low bone mass arising from cellular communications between bone formation and bone resorption. Osteoclastogenesis is induced by M-CSF and RANKL in hematopoietic lineage cells. Once RANK/RANKL complex is formed, TRAF6 is recruited and triggers the activation of
Tuberostemonine stereoisomers are natural alkaloids found in Stemona tuberosa, that are known to have anti-inflammatory and anti-infective properties. Tuberostemonine alkaloids inhibit inflammation by suppressing the expression of inflammatory mediators such as cyclooxygenase and nitric oxide
Protostemonine (PSN) is the main anti-inflammatory alkaloid extracted from the roots of Stemona sessilifolia (known as "Baibu" in traditional Chinese medicine). Here, we reported the inhibitory effects of PSN on lipopolysaccharide (LPS)-induced macrophage activation in vitro and LPS-induced acute
