Biological evaluation of novel benzisoxazole derivatives as PPARδ agonists.

We discovered novel peroxisome proliferator-activated receptor δ agonists with a characteristic benzisoxazole ring. Compound 5 exhibited potent human PPARδ transactivation activity. Furthermore, it stimulated the differentiation of oligodendrocyte precursor cells in vitro. This indicates that this potential drug may be effective for the treatment of demyelinating disorders such as multiple sclerosis.
