: Pharmacologists use molecular modeling and in vitro assays to verify that modulating a target will actually produce a therapeutic effect.

: Pharmacologists work with medicinal chemists to refine "hits" into "lead" compounds. This stage focuses on improving potency, selectivity (to avoid off-target side effects), and drug-like properties. 2. Preclinical Development: Safety and Efficacy

Pharmacology in Drug Discovery and Development: The Critical Path to New Therapeutics

The journey of a new medicine begins with identifying a biological target—such as a protein or gene—linked to a specific disease.
