Synthesis of histamine analogs
Journal of Pharmaceutical Sciences
|January 1, 1976
Summary
Nineteen novel histamine analogs were synthesized and tested for biological activity. None of the compounds demonstrated significant histamine agonist or antagonist properties in various biological screens.
Area of Science:
- Medicinal Chemistry
- Pharmacology
Background:
- Histamine plays a crucial role in various physiological processes.
- Developing selective histamine receptor modulators is important for therapeutic applications.
Purpose of the Study:
- To synthesize and evaluate novel histamine analogs.
- To assess the biological activities of these analogs in comparison to histamine.
Main Methods:
- Synthesis of nineteen histamine analogs, including N-substituted 4-aminoethylimidazoles, N-substituted 2-pyridylethylamines, 2-pyridylcyclohexylamines, and 2-pyridylcyclopropylcarbamates.
- Biological screening for effects on blood pressure, gastric secretion, and nasal decongestion.
Main Results:
- None of the synthesized compounds exhibited significant histamine agonist activity.
- No compounds demonstrated appreciable histamine antagonist properties.
Conclusions:
- The synthesized histamine analogs lack significant histamine-like biological activity.
- Further structural modifications may be needed to achieve desired pharmacological effects.
