Principles of early drug discovery.

Area of Science:

• Pharmaceutical Sciences
• Medicinal Chemistry
• Drug Discovery

Background:

• Drug development is a complex, costly, and time-consuming process, often taking 12-15 years and exceeding $1 billion.
• Identifying and validating a drug target is a critical initial step, drawing from diverse research sources.

Purpose of the Study:

• To review the key preclinical stages involved in the drug discovery process.
• To outline the journey from initial target identification to the selection of a clinical development candidate.

Main Methods:

• Target identification and validation
• Assay development
• High-throughput screening (HTS)
• Hit identification and lead optimization

Main Results:

• The review covers the essential preclinical phases of drug discovery.
• It highlights the streamlined processes used to identify potential drug molecules.
• The selection of a candidate molecule for clinical development is the final preclinical step discussed.

Conclusions:

• The preclinical stages are crucial for identifying and optimizing molecules with drug-like properties.
• Efficiently navigating these stages is vital for successful drug development.
• This review provides a comprehensive overview of these critical early-phase activities.
