Since the concept of New Approach Methodologies (NAMs) was introduced, various methods including in vitro approaches, Threshold of Toxicological Concern (TTC), and computational models have gained favor among toxicological assessment experts. With the increasing capabilities of computational models, key toxicological endpoints such as acute toxicity, skin/eye irritation, sensitization, chronic toxicity, genotoxicity, carcinogenicity, reproductive and developmental toxicity, and toxicokinetics can now be predicted using QSAR models.
