Although single-targeting anti-platelet agents are used extensively in clinics, their limitations in resistance and bleeding have started a trend of combination therapy. Danhong injection (DHI) is a widely prescribed injection medicine for cardiovascular and cerebrovascular diseases in China. However, its precise clinical efficacy and functional components remain unexplored. In this study, we investigated the anti-thrombotic role and its chemical basis of DHI. In a photochemically-induced thrombosis model, DHI effectively dissolved thrombus and ameliorated its derived dry gangrene...

Bilirubin-related adverse reactions (ADR, e.g., jaundice and hyperbilirubinemia) induced by herbs rich in certain polyphenolic acids are widely reported. However, the causes and the mechanisms underlying these ADR are not well understood. The purpose of this article is to determine the mechanism by which certain polyphenolic acids inhibit UGT1A1-mediated bilirubin glucuronidation, leading to jaundice or hyperbilirubinemia. We investigated in vitro inhibitory effects on bilirubin glucuronidation of salvianolic acid A (SAA), salvianolic acid B (SAB), danshensu (DSS), protocatechuic aldehyde (PA), and rosmarinic acid (RA), as well as two Salvia miltiorrhiza injections (DSI and CDI) rich in polyphenolic acids...

Doxorubicin (DOX)-induced cardiotoxicity is a clinically complex syndrome that leads to significant pain to cancer survivors. Endoplasmic reticulum (ER) stress has been suggested to be an important contributor to myocardium dysfunction during this phenomenon. Our previous study proved that Salvianolic acid B (Sal B) protected against doxorubicin induced cardiac dysfunction by inhibiting ER stress and cardiomyocyte apoptosis. However, the underlying molecular mechanism is not yet clearly. In this study, we investigated the protective effect and mechanisms of Sal B againest DOX-induced cardiac injury and ER stress in vivo and in vitro...

Generation and accumulation of the amyloid-β (Aβ) peptide after proteolytic processing of the full length amyloid precursor protein (FL-APP) by β-secretase (β-site APP cleaving enzyme or BACE1) and β -secretase is a main causal factor of Alzheimer's disease (AD). Thus, inhibition of BACE1, a rate-limiting enzyme in the production of Aβ, is an attractive therapeutic approach for the treatment of AD. Recent studies suggest that salvianolic acid B (Sal B) isolated from the radix of Salvia miltiorrhiza Bunge, a Chinese herbal medicine commonly used for the treatment of cardiovascular, cerebrovascular and liver diseases in China...

BACKGROUND/AIMS: It is known that the activation of hepatic stellate cells (HSCs) is a pivotal step in the initiation and progression of liver fibrosis. Aberrant activated Wnt/β-catenin pathway is known to accelerate the development of liver fibrosis. microRNAs (miRNAs)-mediated Wnt/β-catenin pathway has been reported to be involved in HSC activation during liver fibrosis. However, whether long noncoding RNAs (lncRNAs) regulate Wnt/β-catenin pathway during HSC activation still remains unclear...

Myocardial ischemia is a primary cause of sudden death worldwide. Numerous active ingredients of traditional Chinese medicines including danshensu (DSS) and tetramethylpyrazine (TMP) have been widely used for the treatment of myocardial ischemia. To enhance their therapeutic efficacy and improve their drugability, in this work, we designed new DSS and TMP conjugates. Their water solubility and protective effects were studied in vitro and in experimental animal models. The new compounds demonstrated higher activities than the positive control agents acetylated danshensu and tetramethylpyrazine conjugate (ADTM) and salvianolic acid B (SAB) in preventing cells from oxidative insult...
