In the drug development pipeline, which step directly follows lead discovery?

The key idea is refining initial hits into a drug-like candidate. After lead discovery, the next step focuses on lead optimization, an iterative process where chemists adjust the chemical structures of the identified leads to improve potency against the target, enhance selectivity to reduce off-target effects, and improve drug-like properties such as absorption, distribution, metabolism, excretion, solubility, and stability. The aim is to produce a lead compound with strong, selective activity and acceptable safety in early studies, so it can advance to preclinical testing. Target validation is usually addressed earlier in the development process to confirm the target’s relevance, and preclinical testing comes after a robust lead has been optimized.
