A cell-permeable and orally available pyridylsulfone compound that acts as a selective, high affinity PPARβ (PPARδ) ligand (IC₅₀ in PPAR ligand displacement assays = 200 nM against human PPARβ and >10 µM against PPARα or PPARγ) and effectively antagonizes agonist-induced, but not basal, PPARβ transcription activity both in cultures in vitro (IC₅₀ = 126 nM against 2 nM GW501516-induced reporter transcription in CV-1 cells) and in mice in vivo (82% and 71% inhibition of 10 mg/kg GW0742-induced Adrp and Angptl4 mRNA upregulation, respectively, in colon epithelium by 10 mg/kg GSK3787; p.o.) by covalently modifying PPARβ at Cys²⁴⁹. GSK3787 is also shown to exhibit weak agonistic activity toward PPARγ (1.2-fold increase above basal level by 1 µM GSK3787), and effectively block the more potent agonist GW1929 (Cat. Nos. 370695) from further stimulation (1.5 and 3.5-fold above basal by 0.3 µM GW1929 in the presence or absence of 1 µM GSK3787, respectively).
