Target Validation
Target Validation — The process of confirming that modulating a specific biological target produces the desired research outcome, essential before peptide optimization.
What Is Target Validation?
Target validation is the process of confirming that modulating a specific biological target (receptor, enzyme, pathway) will produce the desired therapeutic effect. In peptide drug discovery, target validation uses genetic (knockout animals, siRNA), pharmacological (selective peptide agonists/antagonists), and clinical (human genetic associations) evidence to justify investing in lead optimization.
Validation Methods
- Genetic: CRISPR knockout, transgenic overexpression, human GWAS associations with the target gene
- Pharmacological: Selective peptide ligands demonstrating the expected phenotype in vivo
- Clinical: Human genetic loss-of-function variants that phenocopy the expected therapeutic effect
- Biomarker: Biomarker changes confirming target engagement in proof-of-concept studies
