  1. aNurr1 modulation was determined in a Gal4-Nurr1 hybrid reporter gene assay. Max. activation refers to the maximum effect vs. 0.1% DMSO control. Data are the mean ± SD; n ≥ 3. bNo binding observable in ITC with 100 µM 29 and 30 µM protein (Supplementary Fig. 6). cNuclear receptor selectivity was determined in Gal4-hybrid reporter gene assays for THRα, RARα, PPARα/γ/δ, VDR, FXR, LXRα and RXRα (Fig. 4e). dCytotoxicity was evaluated in N27 (36) and HEK293T (29, 36) cells using a WST-8 assay (Fig. 4f). eSlogP was computed with RDKit63 software.
