Paeonia suffruticosa Andr. (PS) has been used in traditional Chinese medicine for a long time. However, there are no studies that investigate the preventive effects of PS on ultraviolet B (UVB)-induced photoaging. In this study, paeonol (PA) was detected the main compound in PS root. In vitro, PS and PA significantly inhibited UVB-induced phosphorylation of mitogen-activated protein kinase and activator protein 1 in keratinocytes, which consequently led to degradation of procollagen type I. On the other hand, PS and PA increased NAD(P)H:quinone oxidoreductase 1 and heme oxygenase-1 expression, confirmed by greater nuclear accumulation of nuclear factor E2-releated factor 2 (Nrf2)...

Trypanosomiasis, leishmaniasis, and malaria are protozoan infections of public health importance with thousands of new cases recorded annually. Control of these infection(s) with existing chemotherapy is limited by drug toxicity, lengthy parenteral treatment, affordability, and/or the emergence of resistant strains. Medicinal plants on the other hand are used in the treatment of various infectious diseases although their chemical properties are not fully evaluated. In this study, we screened 112 crude extracts from 72 selected Ghanaian medicinal plants for anti-Trypanosoma, anti-Leishmania, and anti-Plasmodium activities in vitro and investigated their mechanisms of action...

Apiaceae plants exhibit a broad spectrum of activities, for instance, antithrombotic, hypotensive, antioxidant, and insecticidal. They also provide a source of phthalides, which display antimicrobial activity. Considering the fact of rising resistance of both bacteria and fungi against commonly used antibiotics, developing of new naturally derived compounds is undeniably attractive approach. To our best knowledge, there are no other reviews concerning this subject in the literature. In view of above, an attempt to summarize an antimicrobial potential of isolated compounds and extracts from Apiaceae plants has been made, by specifying techniques of activity determination and methods of extraction...

REVIEW
Xiaorui Lin, Nan Zhang
Berberine, an isoquinoline alkaloid, is demonstrated to have a variety of pharmacologic effects. Widely used as nonprescription drug for diarrhea, berberine has also broadened its applications in therapies of cardiovascular diseases, diabetes mellitus, tumor, and so forth. However, researches about berberine's protective effects on nervous system are still so insufficient that clinical uses cannot popularize and underlying molecules mechanisms are confused and incomplete. Well-known pathways such as Pl3K/Akt/Bcl-2 pathway, Nrf2/HO-1 pathway, and MAPK signaling pathway help berberine to protect neurons through antiapoptotic, antioxidative, and anti-inflammatory activities...

Though lambertianic acid (LA) was known to exert antitumor effect in liver and prostate cancers, its underlying anticancer mechanism is never reported in breast cancers so far. Thus, in this study, apoptotic mechanism of LA was elucidated in MDA-MB-231 breast cancer cells. Here, LA increased cytotoxicity in MCF-7 and MDA-MB-231 cells; enhanced sub-G1 population, G2/M arrest, and cleaved poly(ADP-ribose) polymerase; activated phosphorylation of AMP-activated protein kinase (AMPK)/acetyl-CoA carboxylase pathway; and also suppressed phosphorylation of AKT and the expression of forkhead box M1 (FOXM1), X-linked inhibitor of apoptosis protein, B-cell lymphoma 2, and CyclinB1 in MDA-MB-231 cells...

Nature has been a source of medicinal treatments for thousands of years, with the use of plants as prototypes for drug development and for the extraction of active compounds. Skin injuries occur regularly in everyday life, and the human skin has the ability to promote repair spontaneously under healthy conditions. However, some intrinsic and external factors may interfere with skins' natural ability, leading to nonhealing lesions and chronic wounds, which directly affect health and quality of life. Thus, attention should be given to this health problem, using an appropriated management when necessary...

Costunolide, a sesquiterpene lactone, is a small molecular monomer extracted from Inula helenium (Compositae). In the present study, we assessed the antileukemia effects of costunolide on the human chronic myeloid leukemia cell line K562 and its combined activity with imatinib. A Cell Counting Kit-8 assay demonstrated that costunolide significantly inhibited K562 cell proliferation and enhanced imatinib-induced anti-proliferative activity. We found that costunolide significantly induced mitochondrial apoptosis in K562 cells by modulating the protein levels of Bcl-2 family members and by inducing caspase activation...
