Eudesmane-type sesquiterpenes are natural sesquiterpenes with anti-inflammatory properties, but their anti-angiogenic activities are not known. The present study demonstrated that 5α-hydroxycostic acid and hydroxyisocostic acid, two eudesmane-type sesquiterpenes (ETSs), isolated from the herb Laggera alata, possessed anti-angiogenic effects. Under non-toxic dosage, ETSs suppressed VEGF‑induced proliferation in human umbilical vein endothelial cells (HUVECs) and vessel formation in zebrafish embryos. Moreover, ETSs inhibited VEGF-stimulated HUVEC migration, stress fibers and tube formation...

Xylose is the second major fermentable sugar present in hard woods and herbs (after d-glucose). Therefore, efficient conversion of xylose to ethanol is essential for the commercialization of lignocellulosic ethanol, which may provide an ideal alternative to fossil fuels in the future. ZLYRHZ7 is a fusant produced by protoplast fusion between two different yeast species, Saccharomyces cerevisiae W5 and Candida shehatae 20335, which is able to utilize xylose to produce ethanol. To improve ethanol production and to quantitatively analyze metabolic pathway in ZLYRHZ7, we used high performance liquid chromatography (HPLC) to assess the utilization rates of xylose, xylitol, and xylulose, and to measure ethanol yields using xylose, xylitol, and xylulose as sole carbon sources...

Alzheimer's disease (AD) is a neurodegenerative disorder of the elderly. As the prevalence of AD rises in the 21st century, there is an urgent need for the development of effective pharmacotherapies. Currently, drug treatments target the symptoms of the disease and do not modify or halt the disease progress. Thus, natural compounds have been investigated for their ability to treat AD. This review examines the efficacy of curcumin, a polyphenol derived from turmeric herb, to treat AD. We summarize the in vivo and in vitro research describing the mechanisms of action in which curcumin modifies AD pathology: curcumin inhibits the formation and promotes the disaggregation of amyloid-β plaques, attenuates the hyperphosphorylation of tau and enhances its clearance, binds copper, lowers cholesterol, modifies microglial activity, inhibits acetylcholinesterase, mediates the insulin signaling pathway, and is an antioxidant...
