It is well-known that hypoxia induces neuronal injury; however, the mechanisms underlying this observed effect remain to be determined. Schisandra chinensis lignans (SCL). The aim of this study was thus to examine the ability of Schisandra chinensis lignans (SCL) to prevent hypoxia-induced neuronal
Hypoxia-inducible factor-1 (HIF-1) represents an important tumor-selective therapeutic target for solid tumors. In search of novel small molecule HIF-1 inhibitors, 5400 natural product-rich extracts from plants, marine organisms, and microbes were examined for HIF-1 inhibitory activities using a
Hypoxia-inducible factor 1 (HIF-1) is a master regulator of hypoxic response and has been a prime therapeutic target for ischemia/reperfusion (I/R)-derived myocardial dysfunction and tissue damage. There is also increasing evidence that HIF-1 plays a central role in regulating aging, both through
Two new lignans, alashinols F and G (1 and 2), together with two known analogues (-)-secoisolariciresinol (3) and meso-secoisolariciresinol (4) were isolated from the stem bark of Syringa pinnatifolia, a Mongolian folk medicine with anti-myocardial ischaemic effects. Their structures were elucidated
The effects of two dibenzocyclooctene lignans on peroxidative damage of aging and ischemic rat brain were studied. Incubation of eight-month-old rat brain mitochondria and membrane suspension with Fe(2+)-cysteine resulted in the formation of malondialdehyde (MDA) and decrease of ATPase activity.
Schisantherin A (SchA), a dibenzocyclooctadiene lignan isolated from the fruit of Schisandra sphenanthera, was reported to possess anti-inflammatory and antioxidant activities. However, its protective effect against renal ischemia-reperfusion (I/R) injury in human renal tubular epithelial cells
Dineolignans manassantin A and B from the plant Saururus cernuus are used in traditional medicine to manage a wide range of ailments such as edema, jaundice, and gonorrhea. Cell-based studies have identified several molecular target candidates of manassantin including NF-κB, MAPK, STAT3, and
Sauchinone, a biologically active lignan isolated from Saururus chinensis, has been reported to show cytoprotective, anti-inflammatory and anti-apoptotic effects. However, little study has been done of the anti-ischemic/hypoxic effect of sauchinone. The present study investigates the
Persicaria orientalis (L.) Spach (internationally accepted and only valid name; synonym: Polygonum orientale L.; family: Polygonaceae), which is named Hongcao in China, is a Chinese herbal medicine that has a wide range of pharmacological effects including treatment to rheumatoid Natural products are rich in several potent bioactive compounds, targeting complex network of proteins involved in various diseases. Vitex negundo (VN), commonly known as "chaste tree", is an ethnobotanically important plant with enormous medicinal properties. Different species of Vitex vary in
