The ligand-activated nuclear receptor peroxisome-proliferator-activated receptor-¦Ã (PPARG or PPAR¦Ã) represents a potential target for a new generation of cancer therapeutics, especially in muscle-invasive luminal bladder cancer where PPAR¦Ã is a critical lineage driver. Here we disclose the discovery of a series of chloro-nitro-arene covalent inverse-agonists of PPAR¦Ã that exploit a benzoxazole core to improve interactions with corepressors NCOR1 and NCOR2. In vitro treatment of sensitive cell lines with these compounds results in the robust regulation of PPAR¦Ã target genes and antiproliferative effects. Despite their imperfect physicochemical properties, the compounds showed modest pharmacodynamic target regulation in vivo . Improvements to the in vitro potency and efficacy of BAY-4931 and BAY-0069 compared to those of previously described PPAR¦Ã inverse-agonists show that these compounds are novel tools for probing the in vitro biology of PPAR¦Ã inverse-agonism.
