| Bioactivity | (E)-3,4,5-Trimethoxycinnamic acid (TMCA) is a cinnamic acid substituted by multi-methoxy groups. (E)-3,4,5-Trimethoxycinnamic acid is an orally active and potent GABAA/BZ receptor agonist. (E)-3,4,5-Trimethoxycinnamic exhibits favourable binding affinity to 5-HT2C and 5-HT1A receptor, with IC50 values of 2.5 and 7.6 μM, respectively. (E)-3,4,5-Trimethoxycinnamic acid shows anticonvulsant and sedative activity. (E)-3,4,5-Trimethoxycinnamic acid can be used for the research of insomnia, headache and epilepsy[1][2][3]. | ||||||||||||
| Invitro | (E)-3,4,5-Trimethoxycinnamic acid (10 μg/mL, 1 h) increases the expressions of GAD65 and γ-subunit of GABAA receptors in the cerebellar granule cells[3].(E)-3,4,5-Trimethoxycinnamic acid (0-10 μg/mL, 1 h) shows a significant increase in Cl- influx[3].
