We successfully synthesized a novel peroxisome proliferator-activated receptor (PPAR)δ selective agonist, namely, compound 20, with a characteristic benzisoxazole ring. Compound 20 exhibited potent human PPARδ transactivation activity and high δ selectivity. Further, it stimulated differentiation of primary oligodendrocyte precursor cells in vitro, indicating that it may be an effective drug in the treatment of demyelinating disorders such as multiple sclerosis.
