Phenylethylamine as a biochemical marker of tiger
Summary
Tiger pheromones are amine and lipid mixtures. Phenylethylamine, a key amine, was consistently found in all tigers, suggesting it could be a species-level biochemical marker.
Area of Science:
- Animal behavior
- Biochemistry
- Zoology
Background:
- Pheromones are crucial chemical signals in animal communication.
- Tiger (Panthera tigris) social and reproductive behaviors are influenced by olfactory cues.
Purpose of the Study:
- To identify key chemical components of tiger pheromones.
- To investigate the potential of specific compounds as species-level biochemical markers.
Main Methods:
- Analysis of pheromone samples from four individual tigers.
- Gas chromatography-mass spectrometry (GC-MS) to identify volatile compounds.
- Lipid analysis to understand compound "fixation" mechanisms.
Main Results:
- Tiger pheromones consist of a complex mixture of amines stabilized by lipids.
- Phenylethylamine was identified as a consistent component across all investigated tiger samples.
- The presence of phenylethylamine suggests a potential species-specific olfactory signature.
Conclusions:
- Phenylethylamine is a significant component of tiger pheromones.
- This compound may serve as a reliable biochemical marker for species identification in tigers.

Adrenergic Agonists: Indirect-Acting Agents
Indirect-acting adrenergic agonists potentiate the effects of endogenous catecholamines through different mechanisms without directly binding to adrenoceptors.
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Adrenergic agonists' structure-activity relationship (SAR) determines their selectivity and efficacy. These agonists comprise a phenylethylamine moiety with an aromatic ring and an ethylamine side chain.
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
Separation of the aromatic...

Drugs Affecting Neurotransmitter Release or Uptake
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...
