anti-seizure

3,4,5-Trimethoxycinnamic acid (O-Methylsinapic acid) (TMCA) is one of the constituents of Polygalae Radix and may exert anti-seizure activity by acting at the GABAA/BZ receptor complex.

Thiocolchicoside (Thiocolchicine 2-glucoside analog) (Muscoril, Myoril, Neoflax) is a muscle relaxant with anti-inflammatory and analgesic effects. It acts as a competitive GABAA receptor antagonist and also glycine receptor antagonist with similar potency and nicotinic acetylcholine receptors to a much lesser extent. It has powerful convulsant activity and should not be used in seizure-prone individuals.

Qingyangshengenin B (Otophylloside B) is a C-21 steroidal glycoside isolated from Qingyangshen. Qingyangshengenin B protects against Aβ toxicity, which decreases Aβ deposition by decreasing the expression of Aβ at the mRNA level. Qingyangshengenin B has antiepileptic and anti-aging effects, it can extend lifespan, increase heat stress-resistance, delay body paralysis, and increase the chemotaxis response in C. elegans models of Alzheimer's disease. Otophylloside B can suppress the seizure-like locomotor activity caused by pentylenetetrazole in zebrafish.

(E)-3,4,5-Trimethoxycinnamic acid (O-Methylsinapic acid) is a natural product from the roots and rhizomes of Notopterygium incisum.
