Drug Discovery Pipeline Target Discovery Lead Finding/Discovery Lead Optimization Exploratory Development Clinical Trials/Registration
Target Discovery Find out where to act Methods: activate/repress receptor or enzyme? different points in network? Methods: Metabolic/Regulatory Network analysis Comparative Genomics Homology Modeling Microarray/CGA
Lead Finding/Discovery Find ‘some’ molecule that does ‘something’ with your target: bind activate repress Methods: HTS Virtual screening Combichem Cheminformatics
Lead Optimization Find better molecule that does exactly what you want, and nothing else specific for target possible side-effects Methods: Targeted screening Rational/Structure-based design QSAR ADME(T) (Absorption, Disposition, Metabolism, Excretion, Toxicology)
Exploratory Development Find out what your molecule does in ‘real life’ uptake, breakdown, toxicity positive and negative effects Methods: Animal models Gene markers Expression profiles ‘Translational modeling’ from animal to human (?) Pharmacokinetic modeling/ADME(T)
