Activated nitrosamines are highly reactive, readily alkylating various organic substrates. This reactivity suggests significant potential for in vivo toxicity, warranting further study of their reaction kinetics.
Area of Science:
- Environmental Chemistry
- Toxicology
- Organic Chemistry
Background:
- Nitrosamines are toxic compounds present environmentally.
- Their reaction mechanisms and toxic pathways require elucidation.
Purpose of the Study:
- Investigate the reaction kinetics of activated nitrosamines.
- Understand the pathways of nitrosamine-induced toxicity.
Main Methods:
- Studied chemical reaction kinetics.
- Examined activated nitrosamine reactions with organic substrates.
Main Results:
- Activated nitrosamines are highly reactive electrophiles.
- A wide range of organic compounds serve as nucleophilic substrates for alkylation.
- This broad substrate compatibility indicates substantial in vivo toxicity potential.
Conclusions:
- Understanding nitrosamine reaction kinetics is crucial for assessing their toxic effects.
- The potential for widespread in vivo alkylation highlights significant toxicological concern.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
