Dan-Deng-Tong-Nao capsules (DDTNCs), a traditional Chinese medicinal preparation consisting of Radix Salvia miltiorrhiza, Radix Pueraria lobata, Erigeron breviscapus, Rhizoma chuanxiong has been used for the treatment of apoplexy and the syndrome of apoplexy involving both collaterals and meridians caused by obstruction of collaterals by blood stasis in China. In this paper, a HPLC-DAD-MS/MS me...

The over-activation of NMDA receptor via the excessive glutamate is believed to one of the most causal factors associated with Alzheimer's disease (AD), a progressive neurodegenerative brain disorder. Molecules that could protect against glutamate-induced neurotoxicity may hold therapeutic values for treating AD. Herein, the neuroprotective mechanisms of dimeric DT-010, a novel derivative of na...

In clinical practice, the traditional Chinese medicinal herbs, Radix Salvia Miltiorrhiza and Carthamus tinctorius L., are usually prescribed in combination due to their significant cardioprotective effects. However, the mechanisms responsible for these combined effects remain unknown. Thus, in this study, we investigated the mechanisms responsible for the combined effects of Danshensu (DSS) and...

Reactive oxygen species (ROS) are important in osteoporosis development. Oxidative stress induces apoptosis of osteoblasts and arrest of their differentiation. Both Danshensu (DSS) and hydrogen sulfide (H2S) produce significant antioxidant effect in various systems. In this study, we synthesized SDSS, a novel H2S-releasing compound derived from DSS, and studied its antioxidant effect in an H2O2...

BACKGROUND Elevated homocysteine is a cardiovascular risk factor in hyperlipidemia. Transsulfuration pathway provides an endogenous pathway for homocysteine conversion to antioxidant glutathione (GSH). Salvianolic acid A (Sal A) contains two molecules of caffeic acid and one molecule of danshensu that is capable of enhancing homocysteine transsulfuration, which led to the hypothesis that Sal A ...

BACKGROUND/AIMS Salvia miltiorrhiza (SM) contains four major aqueous active ingredients, which have been isolated, purified and identified as danshensu (DSS), salvianolic acid A (Sal-A), salvianolic acid B (Sal-B) and protocatechuic aldehyde (PAL), totally abbreviated as SABP. Although SM is often used to treat various cardiovascular diseases in traditional Chinese medicine, the efficacy and fu...

Ischemia-reperfusion (I/R) plays an important role in myocardial injury. In the present study, we aimed to examine the protective effects of Danshensu (DSS) against I/R injury and to elucidate the underlying mechanisms. For this purpose, H9c2 cells were cultured in hypoxic solution in a hypoxic incubator for 2 h, and then cultured in a high oxygen incubator for various periods of time and pre-t...
