| Bioactivity | Corydaline ((+)-Corydaline), an isoquinoline alkaloid isolated from Corydalis yanhusuo, is an AChE inhibitor with an IC50 of 226 µM. Corydaline is a μ-opioid receptor (Ki of 1.23 µM) agonist and inhibits enterovirus 71 (EV71) replication (IC50 of 25.23 µM). Corydaline has anti-angiogenic, anti-allergic and gastric-emptying and antinociceptive activities[1][2][3]. | ||||||||||||
| Invitro | Corydaline (12.5-50 µM; 24 hours) treatment inhibits EV71 replication by suppressing the COX-2 expression and the phosphorylation of JNK MAPK and P38 MAPK but not ERK MAPK in vitro[2]. Corydaline could inhibit the viral RNA synthesis in a dose dependent manner[2]. Western Blot Analysis[2] Cell Line: | ||||||||||||
| In Vivo | Corydaline (10 mg/kg; subcutaneous administration; once) treatment shows antinociceptive effects in mice by significantly inhibiting the writhing behavior[3]. Animal Model: | ||||||||||||
