In order to rapidly identify the phenotypic profile and possible off-target liability effects of novel synthesized thyromimetics for selection of lead compounds for further optimization studies, we performed in vitro screening on a new small library of synthetic thyromimetics. A comprehensive panel of early toxicity assays comprising cytotoxicity on 4 different cell lines (osteosarcoma, U2OS; lung fibroblast, hTERT; human breast adenocarcinoma, MCF7; human embryonic kidney, HEK293), hERG liability, cytochrome P450 inhibition (CYP1A2, CYP2C9, CYP2C19, CYP2D6 and CYP3A4 isoforms), and off-target liability against selected proteins (Aurora B kinase and phosphodiesterase PDE4C1) and epigenetic enzymes (HDAC4, HDAC6, HDAC8, HDAC9 & SIRT7). All the compounds were screened at 10 μM in at least triplicate using well-established in vitro assays with readouts in luminescence or fluorescence polarization mode. The raw data were processed using Microsoft Excel and the Z′ for each assay was calculated (acceptable Z' >0.40). The processed and normalized data were organized in tables and visualized using spider plots. The results which are reported in the present manuscript can be used in prediction studies of early toxicity and off-target liabilities of other thyromimetics using in silico methods. The data reported herein support our research article entitled “Design, synthesis and biological evaluation of novel TRβ selective agonists sustained by ADME-Toxicity analysis” by Runfola M., Sestito S., et al.
