Application:
Daphnetin (CAS: 486-35-1) is a natural coumarin derivative, is a protein kinase inhibitor; inhibits EGFR, PKA and PKC; exhibits anti-inflammatory and anti-oxidant activities. Daphnetin, mainly extracted from Yu Ruixiang Changbai Daphne (Daphne Korean Nakai), Daphne giraldii Nitsche bark, and root bark, is the main efficacy component of the plants D.tangutica Maxim and D.retttsa Hemsl. Changbai daphnes has the pharmacological effects of warming the spleen and stomach, relaxing the muscles and joints, and promoting circulation. In TCM, it’s commonly used as medicines for treatment of injuries. Because Changbai daphne is a pungent and warm natured herbal medicine, it was used to warm the spleen and stomach by dispelling cold. From then on artificially synthesized Daphnetin has been successfully implemented. A large-scale industrial production can be acquired. The followup researches on the metabolism and pharmacological activity of daphnetin were carried out. In 2009, the State Food and Drug Administration of China approved daphnetin capsule to be used in the clinical. It has been verified by a large number of clinical cases that oral daphnetin capsule can significantly improve thromboangiitis obliterans; oral daphnetin has a better curative effect than intramuscular injection of Changbai daphne in patients with angina pectoris due to coronary heart disease. Daphnetin shows an obvious analgesic sedative effect on surgical and nonsurgical pain-relieved patients after intravenous drip or injection of daphnetin; oral daphnetin capsule shows significant therapeutic effects on rheumatoid arthritis.Sufficient Capacity: Sufficient facilities and technicians
