Phenylbiguanide (PBG) is a 5-HT3 agonist used to study the role of 5-HT3 receptors in the central nervous system. [1] It has been found to trigger dopamine release in the nucleus accumbens of rats. [2]
The 5-HT 3 receptor is expressed throughout the central and peripheral nervous systems and mediates a variety of physiological functions. [14] On a cellular level, it has been shown that postsynaptic 5-HT 3 receptors mediate fast excitatory synaptic transmission in rat neocortical interneurons, amygdala, and hippocampus, and in ferret visual ...
The 5-HT 3 receptor antagonists suppress vomiting and nausea by inhibiting serotonin binding to the 5-HT 3 receptors. The highest concentration of 5-HT 3 receptors in the central nervous system are found in the STN and chemoreceptor trigger zone (CTZ), and 5-HT 3 antagonists may also suppress vomiting and nausea by acting at these sites.

meta-Chlorophenylbiguanide (1-(3-Chlorophenylbiguanide, m-CPBG) is an allosteric agonist and modulator of the 5-HT 3 receptor [1] [2] [3] and an antagonist of the α 2A-adrenergic receptor. [4] It has anxiogenic , emetic and hypothermic effects in animal studies.
A new study compares the benefits and risks of taking GLP-1 medications for weight loss, including risks of dementia, addiction, heart disease, and gastrointestinal problems, among others.
One in eight adults in the U.S. has taken Ozempic or another type of GLP-1 drug, surveys show — and now a major new study has revealed a long list of benefits and some little-known risks ...
Galega officinalis (French lilac) was used in diabetes treatment for centuries. [5] In the 1920s, guanidine compounds were discovered in Galega extracts. Animal studies showed that these compounds lowered blood glucose levels.
