BACKGROUND PM014 is a modified form of the Chung-Sang-Bo-Ha-Tang (CSBHT) herbal formula that has been used to treat chronic pulmonary diseases in Korea for centuries. Previously, we developed a formulation of PM014 based on a series of in vitro and in vivo screening efforts that comprises seven

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

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

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

BACKGROUND Stemona tuberosa has long been used in Korean and Chinese medicine to ameliorate various lung diseases such as pneumonia and bronchitis. However, it has not yet been proven that Stemona tuberosa has positive effects on lung inflammation. METHODS Stemona tuberosa extract (ST) was orally

In this study, OVA-induced asthma mice was taken as the model, and orally administered with different concentration of ethanol extracts of crude and processed Stemona tuberosa, in order to determine the cytokine level released from Th1 and Th2 in splenocytes. RT-PCR was carried out to determine 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

Neotuberostemonine (NTS) is one of the main antitussive alkaloids in the root of Stemona tuberosa Lour. This study aimed to investigate the effects of NTS on bleomycin (BLM)-induced pulmonary fibrosis in mice and the underlying mechanism. After BLM administration, NTS were orally administered to

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
