GABAA受容体
Based on studies that looked only at molecular shape, for many years thujone was thought to act similarly to THC on the cannabinoid receptors; however, this has since been proven false. Thujone is a GABAA receptor antagonist and more specifically, a GABAA receptor competitive antagonist. By inhibiting GABA receptor activation, neurons may fire more easily, which can cause muscle spasms and convulsions. This interaction with the GABAA receptor is specific to alpha-thujone. Thujone is also a 5-HT3 antagonist.
