(E)-3,4,5-Trimethoxycinnamic acid (Synonyms: TMCA) |
| Catalog No.GC66255 |
(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.

(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].
Western Blot Analysis[3]
| Cell Line: | Primary cultured cerebellar granule cells |
| Concentration: | 10 μg/mL |
| Incubation Time: | 1 h |
| Result: | Increased expression of GAD65 (glutamic acid decarboxylase) and γ-subunit of GABAA receptors, but did not influence the amounts of a-, b-subunits in the GABAA receptors. |
Cell Viability Assay[3]
| Cell Line: | Primary cultured cerebellar granule cells |
| Concentration: | 1, 3, 5, 10 μg/mL |
| Incubation Time: | 1 h |
| Result: | Produced a significant increase in Cl- influx. |
(E)-3,4,5-Trimethoxycinnamic acid (0-20 mg/kg, IP, once) shows anti-seizure effects[2].
(E)-3,4,5-Trimethoxycinnamic acid (0-10 mg/kg, Orally, once) enhances hypnotic effects in pentobarbital-treated mice[3].
| Animal Model: | Ault male KunMing-strain mice (18-20 g, maximal electroshock (MES) and pentylenetetrazol (PTZ) models)[2] |
| Dosage: | 5, 10 and 20 mg/kg; 10 mL/kg |
| Administration: | IP, once |
| Result: | Significantly decreased the incidence of MES-induced THE (tonic hindlimb extension) to 50% and 20% of the value of the vehicle controls at 10 and 20 mg/kg. Decreased the incidence of MES-induced THE to only 80% at 5 mg/kg. Significantly delayed the onset of myoclonic jerks (MJ), and decreased the seizure severity and mortality compared with the vehicle-treated animals in PTZ seizure model. The incidence of generalized clonic convulsions (stage 4) disappeared at doses of both 10 and 20 mg/kg. |
| Animal Model: | ICR male mice (25-28 g, 10-12 in each group)[3] |
| Dosage: | 2, 5 and 10 mg/kg |
| Administration: | Orally (p.o.), once, 15 min and 1 h prior to pentobarbital injection |
| Result: | Significantly decreased locomotor activity at 10 mg/kg. Increased NREM and total sleep, but decreased wakefulness. |
