(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]. | [Definition]
ChEBI: 3,4,5-trimethoxycinnamic acid is a methoxycinnamic acid with three methoxy substituents at the 3-, 4- and 5-positions. It has a role as an allergen. It is a conjugate acid of a 3,4,5-trimethoxycinnamate. | [in vivo]
(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. |
