Zebrafish (ZF) ADME & Pred Tox meeting, Barcelona, 11-12 April • Jones et al., 2009 (abstract): Evotec/J&J investigation 50 cpds tested in ZF: sensitivity: 86 (n=37) specificity: 77 (n=13) • Hill et al., : comparison of HCS performed on HepG2 (J&J), pri y hepatocytes (Pfizer) and ZF assay using 33 cpds (mainly hepatotoxic drugs). Consequently, ensuring good absorption, distribution, metabolism, excretion, and toxicity (ADME-Tox) is crucial to a drug’s success. eir high genetic homology wi humans and eir high correlation wi mammals like mice ( 98), make zebrafish an excellent model to evaluate ADME-Tox properties. Compliance wi e principles of e 3Rs. Introduction: Chemical impact on heal is usually investigated via e concept of ADME. is is how a chemical is A bsorbed, D istributed, M etabolized, or E liminated in living systems. Not all chemicals are impactful in e same ways, sometimes metabolism, for example, not be an issue because of e way our liver metabolizes e compound and converts it into an inert substance. In vitro ADME/Tox. We perform in vitro absorption, distribution, metabolism, and excretion (ADME) assays for compound screening and lead selection/optimization in drug discovery, IND enabling studies in preclinical evaluation, as well as studies to support clinical development.

ADME/Tox Resources › Gibco Human Spheroid-Qualified Hepatocytes › Pri y hepatocytes isolated from e liver are effective tools for e in vitro evaluation of metabolism, drug-drug interactions, hepatotoxicity, and transporter activity. For many years, biologists have relied on in vitro 2D cell culture models to perform preclinical ADME-Tox assays. While ese models are useful, ey are limited in eir translatability to drug metabolism and toxicity in humans. Recently, in vitro 3D organoid models at more closely mimic human biological systems have shown promise in supporting ADME-Tox studies in drug discovery.
