延胡索甲素 - Reference Information
| Overview | Corydalis yanhusuo (Corydalis yanhusuo) is a quaternary amine alkaloid. T.Wang) one of the main active ingredients in tubers. Modern pharmacology shows that Corydalis a not only has analgesic, exciting uterus, anti-arrhythmic effect, Corydalis A has anti-morphine-like effect, can also be used for the preparation of drug detoxification. |
| Application of | Corydalis a can effectively inhibit Virus of the replication of the respiratory tract in a non-toxic range, it can be further developed into a drug for treating or preventing Virus respiratory diseases, and has a wide application prospect. |
| biological activity | Corydaline (( )-Corydaline) is an isoquinoline alkaloid extracted from Corydalis yanhusuo, it is an AChE inhibitor with an IC50 of 226 μm. Corydaline is a μ-opioid receptor (Ki 1.23 µm) agonist that inhibits intestinal Virus 71 (EV71) replication (IC50 25.23 µm). Corydaline has anti-angiogenic, anti-allergic, gastric emptying and antinociceptive effects. |
| Target | IC50: 226 µm (AChE); 25.23 µm (Enterovirus 71) Ki: |
| Cell Line: | Vero cells infected with EV71 |
| Concentration: | 12.5 µM, 25 µM, 50 µM |
| Incubation Time: | 24 hours |
| Result: | Reduced the phosphorylation of P38 MAPK and JNK MAPK and the expression of COX-2. Showed antinociceptive effects in mice. |
| Animal Model: | Male CD1 mice (30-35 g, 7-8 weeks old) injected with acetic acid |
| Dosage: | 10 mg/kg |
| Administration: | Subcutaneous administration; once |
| Use | Corydalis a analgesic, sedative, hypnotic effect. for content determination/identification/pharmacological experiments. Pharmacological Efficacy: analgesic effect. |
