The alkaloids N-methylhydrasteine hydroxylactam and 1-methoxyberberine chloride were isolated from Corydalis longipes. Both alkaloids showed high efficacy individually (in concentration of 50-150 ppm) and also in a 1:1 mixture against spore germination of some fungi, viz. Alternaria alternata, A.
Narceine methyl ester and narceine are potent alkaloids which were isolated from Corydalis longipes were found effective in vitro at very low concentration, i.e., 100~500 ppm against spore germination of some test plant pathogenic fungi (Alternaria solani, A. tagetica, Cercospora abelmoschi,
Phytochemicals have been considered as alternatives for synthetic fungicides because of their biodegradability and low toxicity. In this study, we found that the methanolic extract of Corydalis ternata suppressed the development of plant diseases caused by Puccinia triticina and Colletotrichum
Chemotherapy-induced peripheral neuropathy (CIPN) is a common complication of cisplatin, which is characterized by intolerable paresthesia, burning, and hyperalgesia, and severely impacts the life quality of patients. However, no clearly potent drug has been found for clinical medication due to its
Tetrahydroprotoberberines (THPBs) represent a series of compounds extracted from the Chinese herb Corydalis ambigua and various species of Stephania. THPBs, dependent on the presence of hydroxyl groups in its structure, are divided into three types: nonhydroxyl-THPBs, monohydroxyl-THPBs and
Numerous species of the genus Corydalis (Papaveraceae) produce a large spectrum of benzylisoquinoline alkaloids (BIA), some of which are of potential therapeutic value, but no information on sites of their biosynthesis and compartmentation is available. This study focuses on the biosynthesis,
In this report, the anti-hepatitis B virus (HBV) activity of dehydrocheilanthifoline (DHCH), a quaternary ammonium alkaloid isolated from the traditional Chinese medicine Corydalis saxicola Bunting (Papaveraceae), was determined in vitro. Following six days of treatment, DHCH efficiently suppressed
Gut microbiota dysbiosis induced by antibiotics is strongly connected with health concerns. Studying the mechanisms underlying antibiotic-induced gut microbiota dysbiosis could help to identify effective drugs and prevent many serious diseases. In this study, in rats with antibiotic-induced gut
OBJECTIVE
The (2'S,7'S)-O-(2-methylbutanoyl)-columbianetin (OMC) is a novel secondary metabolite extracted from Corydalis heterocarpa, which has long been used as a folk medicine for various inflammatory diseases in Korea. We examined the effect of OMC on allergic rhinitis (AR).
METHODS
We assessed
Methanolic extract (CM-ext) from tubers of Corydalis turtschaninovii forma yanhusuo has been screened for activity in experimental models of types I-IV allergy. In type I allergic models, CM-ext at doses of 200, 500 mg/kg, p.o. inhibited 48-h homologous passive cutaneous anaphylaxis (PCA) in rats
Current breast cancer therapies have limitations in terms of increased drug resistance resulting in short-term efficacy, thus demanding the discovery of new therapeutic agents. In this study, cytotoxic activity and apoptotic effects of govaniadine isolated from Corydalis govaniana Wall. roots were
In recent years, the morbidity of Alzheimer's disease in the world has become more and more serious. Therefore, it is an important means to find new drugs for treating AD from traditional medicines. It was found that Corydalis edulis Maxim. has a significant effect in the treatment of While screening extracts of natural products in search of anticholinesterase activity, we found that a total methanolic extract of the tuber of Corydalis ternata (Papaveraceae) showed significant inhibitory effects on acetylcholinesterase. Further fractionation of this extract using
Myoblast differentiation is fundamental to the development and regeneration of skeletal muscle after injury or disease. MyoD family transcription factors play a key role to promote myoblast differentiation. In a screen for MyoD activators, we identified tetrahydropalmatine (THP), a natural compound
BACKGROUND
Corydalis dubia is used in Bhutanese traditional medicine as a febrifuge and for treating infections in the blood, liver and bile which correlate to the signs and symptoms of malarial and microbial infections.
OBJECTIVE
To validate the ethnopharmacological uses of the plant and to
