Diterpenoid Alkaloids from Delphinium liangshanense.

Two new C-diterpenoid alkaloids of the lycoctonine-type (liangshanine A and liangshanine B) and nineteen known compounds (3-21) were isolated from the whole plant of Delphinium liangshanense W. T. Wang, and all the compounds were identified by different spectroscopic analyses, such as IR, HR-ESI-MS and NMR.

Pyronaridine induces apoptosis in non-small cell lung cancer cells by upregulating death receptor 5 expression and inhibiting epidermal growth factor receptor.

Lung cancer is the leading cause of cancer death. Pyronaridine, a synthetic drug of artemisinin, has been used in China for over 30 years for the treatment of malaria, but its effect on non-small cell lung cancer (NSCLC) cells is rarely reported. In this study, we determined the efficacy of pyronaridine in four different NSCLC cell lines and explored its mechanism in H1975.

[Study progress on chemical compounds, pharmacological action and clinical application of Naoxintong capsule].

Naoxintong capsule (NXTC) is an oral Chinese preparation produced by modern technology, derived from the classic preparation of Buyang Huanwu decoction which was recorded by WANG Qing-ren (Qing dynasty) in Yilingaicuo Juanxia Tanweilun. NXTC is composed of 16 herbs including insect herbs and some blood circulation herbs, with the effects of supplementing Qi and activating blood circulation, dispersing blood stasis and dredging collaterals. In clinical application, it is mainly used for stroke, cerebral infarction, vascular dementia, ischemic cerebrovascular disease, transient ischemic attack, coronary heart disease, angina pectoris, ischemic cardiomyopathy, diabetic cardiomyopathy, myocardial infarction, chronic heart failure, chronic complications of diabetes, essential hypertension, hyperlipidemia and other cardiovascular and cerebrovascular diseases, and has achieved good therapeutic effect on above diseases or their concurrent diseases.
