Spasmolytic agents. 2. 1,2,3,4-Tetrahydro-2-naphthylamine derivatives
Journal of Medicinal Chemistry
|November 1, 1982
Summary
New spasmolytic agents derived from tetrahydro-2-naphthylamine selectively target colon nerves. Compound 63 demonstrated superior activity compared to mebeverine, offering potential for novel gastrointestinal treatments.
Area of Science:
- Medicinal Chemistry
- Pharmacology
- Organic Synthesis
Background:
- Spasmolytic agents are crucial for managing gastrointestinal disorders.
- Existing treatments like mebeverine have limitations.
- Developing novel compounds with improved selectivity and efficacy is essential.
Purpose of the Study:
- To synthesize novel N-[(Benzoyloxy)alkyl]-1,2,3,4-tetrahydro-2-naphthylamine derivatives.
- To evaluate the spasmolytic activity of these synthesized compounds.
- To identify structure-activity relationships for enhanced therapeutic potential.
Main Methods:
- Synthesis of tetrahydro-2-naphthylamine derivatives.
- In vivo evaluation of spasmolytic activity in anesthetized dogs.
- Comparative analysis against a reference drug (mebeverine).
Main Results:
- Several synthesized compounds exhibited significant spasmolytic activity.
- A notable nerve-selective effect on the colon was observed, distinguishing from stomach effects.
- Compound 63, N-ethyl-N-[6-(3,4-dimethoxybenzoyl)oxy]hexyl]-1,2,3,4-tetrahydro-6-methoxy-2- napththylamine hydrochloride, showed the highest potency.
Conclusions:
- The synthesized N-[(Benzoyloxy)alkyl]-1,2,3,4-tetrahydro-2-naphthylamine derivatives represent a promising class of spasmolytic agents.
- Compound 63 is a potent spasmolytic agent with potential for treating colon-specific disorders.
- Further research into these compounds could lead to improved therapies for gastrointestinal conditions.
