Genus Veratrum plants contain a diversity of steroidal alkaloids, so far at least 184 steroidal alkaloids attributed to cevanine type(A-1～A-69), veratramine type(B-1～B-21), jervanine type(C-1～C-31), solanidine type(D-1～D-10) and verazine type(E-1～E-53), respectively, have been isolated and identified in the genus Veratrum. Their pharmacological activities mainly focused on decreasing blood pressure, anti-platelet aggregation and anti-thrombosis, anti-inflammatory and analgesic, and antitumor effect. This paper classified and summarized the 184 kind of steroidal alkaloids from the Veratrum plants and their major pharmalogical activities in order to provide the scientific basis for the further development and utilization of active alkaloids.

Steroidal saponins have a wide range of pharmacological effects and biological activities, such as anti-tumor, antifungal, hypoglycemic, immune regulation, insecticides, etc. In the last ten years, some new structures of steroidal saponins compounds were found from natural plants, they have some new and different activities. In order to accelerate the research on the drug innovation of steroidal saponins, we summarized the new progress of the research on such compounds.

Primary health care providers play a critical role in maintaining public health, and the appropriate prescription of pharmaceutical products is a major component of their practice. This series of articles entitled 'Clinical Pharmacology Review for Primary Health Care Providers' is intended to help primary health care providers select more appropriate prescriptions for frequently used drugs based on up-to-date information. We expect that this effort will contribute to improvements in public health and diminish unnecessary drug use.

Cynanchum is one of the most important genera in Asclepiadaceae family, which has long been known for its therapeutic effects. In this genus, 16 species are of high medicinal value. The extracts of the root and/or rhizome parts have been applied in traditional Chinese medicines (TCM) for the prevention and treatment of various illnesses for centuries. C21 steroids, as the typical constituents of Cynanchum species, possess a variety of structures and pharmacological activities. This review summarizes the comprehensive information on phytochemistry and pharmacology of C21 steroid constituents from Cynanchum plants, based on reports published between 2007 and 2015. Our aim is to provide a rationale for their therapeutic application, and to discuss the future trends in research and development of these compounds. A total of 172 newly identified compounds are reviewed according to their structural classifications. Their in vitro and in vivo pharmacological studies are also reviewed and discussed, focusing on antitumor, antidepressant, antifungal, antitaging, Na(+)/K(+)-ATPase inhibitory, appetite suppressing and antiviral activities. Future research efforts should concentrate on in vitro and in vivo biological studies and structure activity relationship of various C21 steroid constituents.

While hormonal changes during the ovulatory cycles affect multiple body systems, medical management, including medication dosing remains largely uniform between the sexes. Little is known about sex-specific pharmacology in women. Although hormonal fluctuations of the normal menstruating process alters women's physiology and brain biochemistry, medication dosing does not consider such cyclical changes. Using schizophrenia as an example, this paper illustrates how a woman's clinical symptoms can change throughout the ovulatory cycle, leading to fluctuations in medication responses. Effects of sex steroids on the brain, clinical pharmacology are discussed. Effective medication dose may be different at different phases of the menstrual cycle. Further research is needed to better understand optimal treatment strategies in reproductive women; we present a potential clinical trial design for examining optimal medication dosing strategies for conditions that have menstruation related clinical fluctuations.

OBJECTIVE: To explore the proliferation and differentiation-inducing effects of aminosteroid H42648 on K562 leukemia cells. METHODS: The effects of H42648 on K562 cell proliferation were determined by cell count, colony count and MTT assay, and the differentiation by morphology, benzidine stain and flow cytometry. RESULTS: The growth of K562 cells was inhibited after the treatment with H42648 for 5 days. The inhibition rates for K562 cells in MTT assay were (26.90+/-3.18)% and (43.26+/-2.54)% after the treatment by 10(-8)mol/L and 10(-6)mol/L H42648. The inhibitions for K562 cells in colony culture assay were (22.21+/-9.20)% and (48.71+/-8.24)% at 10(-8)mol/L and 10(-6)mol/L H42648, respectively. H42648 also induced K562 cells toward erythroid differentiation. It was verified by benzidine stain that the OD value at 10(-8)mol/L H42648 was increased by (153+/-17.65)% compared with the control, and at 10(-6)mol/L H42648 the OD value was increased by (250+/-4.60)% compared with the control. The morphology showed the differentiation tendency of K562 cells after the treatment. Data from flow cytometry showed that after the treatment with 10(-6)mol/L H42648 for 4 days, positive CD71 expression in differentiated K562 cells was 89.91%. CONCLUSION H42648 can inhibit the proliferation of K562 cell lines and induce toward erythroid differentiation. H42648 may become a new lead for the differentiation-inducing therapy for leukemia.

Morus alba L. (mulberry) is a well-known deciduous tree, belonging to the genus of Morus of Moraceae famlily. Its leaves, twigs, roots (bark) and fruits are widely used in the traditional Chinese medicine. The active constituents of mulberry contained flavonoids, alkaloids, steroids, coumarins, with the significant hypoglycemic, hypolipidemic, antihypertension, anti-oxidation, anti-inflammatory, anti-bacterial, anti-tumor and immunomodulatory activities. This review summarized the research progress of the major pharmacological activity, pharmacokinetics and drug-drug interaction based on CYPs and transporters of mulberry and its active constituents.

Their pharmacological effects include blood pressure-lowering, blood sugar-lowering, blood lipids-regulating, prevention of osteoporosis, anti-inflammation, liver protection, anti-cancer and so on. Their efficacy and mechanism from different parts are slightly different. In this paper, the chemical composition, pharmacological action and mechanism of different parts of E. ulmoides were systematically summarized, as well as its quality control and processing research, to provide theoretical basis for further rational development and utilization of E. ulmoides.

OBJECTIVETo evaluate the inhibitive effect of C-21 steroidal glycosides from the root of Cynanchum auriculatum (CGB) on rat glioma C6 cells.

METHODSC6 cells were treated with CGB for 24, 48,72 h at concentration of 30, 60, 120 mg/L, respectively. MTT assay was used for evaluating cell viability; fluorescence-activated cell sorting analysis after Annexin V/propidium iodide staining or single propidium iodide staining was used to test cell apoptosis and cell cycle.

RESULTSCGB at 30, 60, 120 mg/L concentration-dependently decreased C6 cell viability (P<0.001). CGB at 60 and 120 mg/L induced C6 cell apoptosis and cell cycle arrest. The fraction of G0/G1 cells was increased (P<0.05) and that of S phase cells was decreased (P<0.01).

CONCLUSIONCGB can inhibit the growth of rat glioma C6 cells, and induce apoptosis and G0/G1 cell cycle arrest.
