Receptorome screening for CNS drug discovery.

Area of Science:

• Pharmacology
• Neuroscience
• Drug Discovery

Background:

• G protein-coupled receptors (GPCRs) are crucial targets for approximately 50% of marketed drugs, particularly for central nervous system (CNS) disorders.
• Despite their importance, less than 10% of known GPCRs are currently utilized as therapeutic targets.
• This highlights a substantial unmet need and opportunity in CNS drug development.

Purpose of the Study:

• To explore the potential of G protein-coupled receptors (GPCRs) as targets for novel central nervous system (CNS) drug discovery.
• To identify novel ligand-receptor interactions by systematically screening the 'receptorome'.
• To describe discovery-based approaches for identifying new CNS drug targets.

Main Methods:

• Systematic screening of the 'receptorome' to identify novel ligand-receptor interactions.
• Discovery-based approaches for identifying molecular targets of psychoactive compounds.
• Review of recent examples of novel ligand-receptor discoveries.

Main Results:

• Discovery of novel ligand-receptor interactions through systematic screening.
• Identification of previously uncharacterized GPCRs as potential drug targets.
• Elucidation of molecular targets for psychoactive compounds.

Conclusions:

• G protein-coupled receptors (GPCRs) represent a vast, largely untapped resource for developing new central nervous system (CNS) therapeutics.
• Systematic screening and discovery-based approaches are effective in identifying novel GPCR drug targets.
• Further exploration of the 'receptorome' holds significant promise for advancing CNS drug discovery.
