Tanshinone IIA (Tan-IIA) is derived from the dried roots of Salvia miltiorrhiza Bunge, a traditional Chinese medicine. Although Salvia miltiorrhiza has been applied for many years, the toxicity of the mono-constituent of Salvia miltiorrhiza, tanshinone IIA, is still understudied. This study evaluated the cardiotoxicity and developmental malformations of Tan-IIA by using zebrafish normal embryos and dechorionated embryos. After treatment with Tan-IIA in different concentrations for four-day periods, obvious pericardial edema, spinal curvature, and even missing tails were observed in zebrafish embryos...

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...

Highly oxidized tanshinones are pharmacological ingredients extracted from the medicinal model plant Salvia miltiorrhiza and are mainly used to treat cardiovascular diseases. Previous studies have confirmed that cytochrome P450 mono-oxygenases (CYP450s) have a key function in the biosynthesis of tanshinones; however, no solid evidence links oxidation to the 2-oxoglutarate-dependent dioxygenase (2OGD) superfamily. Here, we identified 132 members of the DOXB and DOXC subfamilies of 2OGD by scanning the 2OG-FeII Oxy domain using a genome-wide strategy in S...

BACKGROUND: Sevoflurane is the most widely used inhalational anesthetic in pediatric medicine. Despite this, sevoflurane has been reported to exert potentially neurotoxic effects on the developing brain. Clinical interventions and treatments for these effects are limited. Tanshinone IIA (Tan IIA), extracted from Salvia miltiorrhiza (Danshen), has been documented to alleviate cognitive decline in traditional applications. Therefore, we hypothesized that preadministration of Tan IIA may attenuate sevoflurane-induced neurotoxicity, suggesting that Tan IIA is a new and promising drug capable of counteracting the effects of cognitive dysfunction produced by general anesthetics...

Salvia miltiorrhiza is a well-known material of traditional Chinese medicine. Understanding the regulatory mechanisms of phenolic acid biosynthesis and metabolism are important for S. miltiorrhiza quality improvement. We report here that S. miltiorrhiza contains 19 polyphenol oxidases (PPOs), forming the largest PPO gene family in plant species to our knowledge. Analysis of gene structures and sequence features revealed the conservation and divergence of SmPPOs. SmPPOs were differentially expressed in plant tissues and eight of them were predominantly expressed in phloem and xylem, indicating that some SmPPOs are functionally redundant, whereas the others are associated with different physiological processes...
