Toxicology
Toxicology — The scientific study of the adverse effects of chemical substances on living organisms, essential for characterizing safety profiles of research compounds.
What Is Toxicology?
Toxicology is the study of adverse effects of chemical substances on living organisms. In peptide drug discovery, toxicology studies determine the safety profile of a compound before clinical trials. Peptides generally show favorable toxicology profiles compared to small molecules due to their high target selectivity and degradation to natural amino acids.
Preclinical Toxicology Studies
- Acute toxicity: Single high-dose administration to determine LD50 and maximum tolerated dose
- Repeat-dose toxicity: 14-day, 28-day, or 90-day dosing studies to identify target organ toxicity
- Genotoxicity: Ames test, chromosomal aberration assays (peptides rarely show genotoxicity)
- Immunogenicity: Assessment of anti-drug antibody (ADA) formation against the peptide
- Safety pharmacology: Cardiovascular (hERG), respiratory, and CNS safety panels
Frequently Asked Questions
