Novel bivalent positive allosteric modulators of AMPA receptor

Area of Science:

• Neuroscience
• Medicinal Chemistry
• Pharmacology

Background:

• AMPA receptors are crucial for synaptic plasticity and cognitive functions.
• Dysfunction of AMPA receptors is implicated in neurodegenerative diseases and cognitive impairments.
• Developing potent and selective modulators is a key therapeutic strategy.

Purpose of the Study:

• To design and characterize a novel positive allosteric modulator (PAM) of AMPA receptors.
• To explore a new class of bivalent AMPA receptor ligands based on a bicyclo[3.3.1]nonane scaffold.
• To establish a foundation for developing new therapeutics for neurological disorders.

Main Methods:

• Computer-aided molecular modeling for drug design.
• Synthesis of novel bivalent ligands incorporating a bicyclo[3.3.1]nonane core.
• Experimental validation of ligand potency and efficacy at AMPA receptors.

Main Results:

• A novel positive allosteric modulator of AMPA receptors was successfully designed.
• The compound demonstrated exceptionally high potency, confirmed experimentally in the picomolar range.
• The ligand represents a new structural class of bivalent AMPA receptor modulators.

Conclusions:

• The designed bicyclo[3.3.1]nonane-based ligand is a highly potent PAM of AMPA receptors.
• This novel scaffold offers a promising starting point for drug development.
• Potential applications include treatments for neurodegenerative diseases, cognition enhancement, and memory improvement.
