OBJECTIVE
This study aimed to investigate the effects of five tanshinones, the lipophilic components from Danshen (Salvia miltiorrhiza), on CYP2C19 activity in pooled human liver microsomes (HLMs).
METHODS
The effects of tanshinones on CYP2C19 activity were compared by enzyme inhibition study using
Cancer-induced bone pain (CIBP) is a common chronic pain characterized by 2 components, ongoing pain and breakthrough pain. Tanshinone IIA (TSN IIA) is a bioactive constituent of the traditional Chinese medicine Danshen, which has been reported to have an antinociceptive effect on neuropathic and
BACKGROUND
Spinal cord injury (SCI) is one of the most severe central nervous system injuries. Currently, transplanting bone marrow mesenchymal stem cells (BMSCs) is considered a therapeutic option for SCI. Tanshinone IIA (TIIA) is one of the extracts obtained from Salvia miltiorrhiza Bunge, which
Exposure to solar ultraviolet (UV) radiation is a causative factor in skin photocarcinogenesis and photoaging, and an urgent need exists for improved strategies for skin photoprotection. The redox-sensitive transcription factor Nrf2 (nuclear factor-E2-related factor 2), a master regulator of the
The effects of Danshen and its active components (tanshinone I, tanshinone IIA, dihydrotanshinone and cryptotanshinone) on CYP2D6 activity was investigated by measuring the metabolism of a model CYP2D6 probe substrate, dextromethorphan to dextrorphan in human pooled liver microsomes. The ethanolic

The dry root and rhizome of
Salvia miltiorrhiza Bunge, or Danshen, is a well-known traditional Chinese medicine with anticoagulant activity. Taking into account that thrombin (THR) and factor Xa (FXa) play crucial roles in the coagulation cascade, it is
Chitosan (CS), a naturally occurring high-molecule polymer, which is stable in vivo, has proved to be a useful biomaterial. The extract of danshen (Radix Salviae miltiorrhizae), a medicinal herbal, was developed with CS-gelatin as an implant for the promotion of anastomosing and healing on muscles
The pregnane X receptor (PXR) plays a critical role in the regulation of human cytochrome P450 3A4 (CYP3A4) gene. In this study, we investigated the effect of an array of compounds isolated from Chinese herbal medicines on the activity of PXR using a luciferase reporter gene assay in transiently
Tanshinones are important diterpenoid secondary metabolites from Salvia miltiorrhiza, widely used as cardiovascular and cerebrovascular medicines. CYP76AH1 is a membrane-associated cytochrome P450 enzyme and plays a critical role in the biosynthetic pathway of tanshinones. To clarify the
Alzheimer's disease (AD) is characterized by fibrillar deposits of amyloid-β (Aβ) peptides and neurofibrillary tangles of Tau proteins. Aβ peptides are composed of 37 to 49 residues, in which the Aβ42 isoform is particularly toxic and aggregation-prone and is enriched in the plaques of AD brains and
