Oxotremorine

Oxotremorine.svg

Oxotremorine is a muscarinic receptor agonist that is primarily used in pharmacological research to study the effects of muscarinic acetylcholine receptor activation. It is a synthetic compound that mimics the action of the neurotransmitter acetylcholine on muscarinic receptors.

Chemical Structure and Properties

Oxotremorine has the chemical formula C12H18N2O and a molecular weight of 206.29 g/mol. It is a member of the pyrrolidine class of compounds and contains a pyrrolidine ring attached to a methyl group and an acetyl group.

Mechanism of Action

Oxotremorine acts as an agonist at muscarinic acetylcholine receptors, which are a subtype of acetylcholine receptors. These receptors are G protein-coupled receptors that mediate various physiological functions, including smooth muscle contraction, heart rate modulation, and glandular secretion. By binding to these receptors, oxotremorine can induce effects similar to those of acetylcholine, such as bradycardia, increased gastrointestinal motility, and salivation.

Pharmacological Effects

Oxotremorine is known for its ability to induce tremors, which is a characteristic effect of muscarinic receptor activation. This property makes it a valuable tool in the study of Parkinson's disease and other neurological disorders that involve tremors. Additionally, oxotremorine can affect central nervous system functions, leading to changes in behavior, cognition, and motor control.

Research Applications

Oxotremorine is widely used in neuroscience and pharmacology research to investigate the role of muscarinic receptors in various physiological and pathological processes. It is often used in animal models to study the effects of muscarinic receptor activation on brain function and behavior. Researchers also use oxotremorine to screen for potential therapeutic agents that target muscarinic receptors.

Safety and Toxicity

While oxotremorine is a valuable research tool, it can be toxic at high doses. Its effects on the cardiovascular system, respiratory system, and gastrointestinal system can lead to adverse reactions, including hypotension, bronchoconstriction, and diarrhea. Therefore, it is important to handle oxotremorine with care and use appropriate safety measures in research settings.
