Cryptotanshinone (CTS), a major constituent from the roots of Salvia miltiorrhiza (Danshen), is widely used in the treatment of coronary heart disease, stroke and less commonly Alzheimer's disease. Our recent study indicates that CTS is a substrate for P-glycoprotein (PgP/MDR1/ABCB1). This study has

Ischaemic stroke represents one of the main causes of disability. According to the broad investigations, it is widely assumed that the contribution of inflammatory mediators is strongly involved in its pathogenesis. Hence, it seems that stroke treatment needs more efficient and inflammatory-targeted

We previously reported neuroprotective activity of the botanical anti-cancer drug candidate PBI-05204, a supercritical CO2 extract of Nerium oleander, in brain slice and in vivo models of ischemic stroke. We showed that one component of this neuroprotective activity is mediated through its principal

OBJECTIVE Heme oxygenase-1 (HO-1) is an inducible Phase 2 enzyme that degrades toxic heme; its role in cerebral ischemia is not fully understood. We hypothesize that chemically induced HO-1 upregulation with the novel triterpenoid CDDO-Im (2-cyano-3,12 dioxooleana-1,9 dien-28-oyl imidazoline), a

The extracts from the root of Salvia miltiorrhiza are widely used in the treatment of angina and stroke. In this study, we have investigated the role of P-glycoprotein (P-gp) in the transport of tanshinone I (TSI), a major active constituent of S. miltiorrhiza. The TSI transport across Caco-2

Saponins, an important group of bioactive plant natural products, are glycosides of triterpenoid or steroidal aglycones. Their diverse biological activities are ascribed to their different structures. Saponins have long been recognized as key ingredients in traditional Chinese medicine. Accumulated

Nao-Mai-Tong (NMT), a Chinese herbal formula, is used for treating ischemia cerebral apoplexy. To discover the components of NMT with potential in vivo bioactivity and investigate the differences between NMT and its single herb components, this study rigorously compared plasma samples collected from

Marinobufagenin may mediate the impact of salty diets on left ventricular hypertrophy by disrupting the protective function of coronary microvascular endothelium.

Individuals who eat salty diets and who are "salt-sensitive" tend to have increased left ventricular mass, independent of blood pressure; this phenomenon awaits an explanation. It is clear that local up-regulation of angiotensin II (AngII) production and activity play a key role in the induction of
