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 |
