To develop an optimal bioprocess for the production of tanshinone which is mainly used for the treatment of cardiocerebral vascular disease, the tanshinone biosynthetic pathway regulation must be better understood. In this paper, expression of tanshinone biosynthetic pathway related genes as well as tanshinone accumulation in Salvia miltiorrhiza hairy root(More)
BACKGROUND Tropane alkaloids (TA) including anisodamine, anisodine, hyoscyamine and scopolamine are a group of important anticholinergic drugs with rapidly increasing market demand, so it is significant to improve TA production by biotechnological approaches. Putrescine N-methyltransferase (PMT) was considered as the first rate-limiting upstream enzyme(More)
Tanshinone is widely used for treatment of cardio-cerebrovascular diseases with increasing demand. Herein, key enzyme genes SmHMGR (3-hydroxy-3-methylglutaryl CoA reductase) and SmDXR (1-deoxy-d-xylulose 5-phosphate reductoisomerase) involved in the tanshinone biosynthetic pathway were introduced into Salvia miltiorrhiza (Sm) hairy roots to enhance(More)
Agrimonolide and desmethylagrimonolide are the main bioactive polyphenols in agrimony with well-documented antioxidant, anti-diabetic, and anti-inflammatory potential. We report here for the first time that agrimonolide and desmethylagrimonolide stimulate the expression of phase II detoxifying enzymes through the Nrf2-dependent signaling pathway.(More)
Tropane alkaloids (TAs) including hyoscyamine, anisodamine, anisodine and scopolamine are widely used as anticholinergic agents, which act on the parasympathetic nervous system, and their clinical demands are increasing rapidly. Anisodus acutangulus is a solanaceous perennial plant that is endemic to China with good potential for TA production and(More)
The four tropane alkaloids have played a pivotal role in controlling diseases such as the toxic and septic shock, the organophosphorus poison and the acute lung injury. Here, the elicitation effect of different elicitors on the production of tropane alkaloids and the molecular mechanism of enzyme genes in the pathway was firstly demonstrated in hairy roots(More)
