Primary rat hepatocyte cell cultures were used to determine half-maximal Inhibition Concen-trations (IC50) of the drug-carrier library. Drug-carrier library, at concentrations <50 mu g/mL, is benign to primary rat hepatocytes as determined using albumin and urea secretions. Albumin, as a hepatic biomarker, exhibited a more sensitive and faster outcome, compared to urea, for the determination of the IC50 value of LPNs. Temporal measurements of hepatic biomarkers including urea and albumin, and rigorous physi-cochemical (hydrodynamic diameter, surface charge, etc.) characterization, should be combined to evaluate the hepatotoxicity of drug carrier libraries in screens.(c) 2023 Published by Elsevier Inc.eninfo:eu-repo/semantics/openAccessLipopolymer nanoparticle (LPN)NanotoxicityPrimary rat hepatocyteIn vitro cultureHepatotoxicityArticle36623713Q148WOS:000975315200001Q2
