The present invention provides a retinoid-related receptor (except retinoic acid receptors) function regulating agent comprising a compound represented by the formula:
1
wherein one of R
1
and R
2
is an optionally substituted monocyclic aromatic hydrocarbon group or an optionally substituted monocyclic aromatic heterocyclic group containing one heteroatom, and the other is a hydrogen atom and the like; B is a 5- or 6-membered heterocycle (except 1,3-azole); A is an optionally substituted aromatic hydrocarbon group or an optionally substituted aromatic heterocyclic group; and R
3
is a hydrogen atom and the like, or a salt thereof, which is useful as an agent for the prophylaxis or treatment of diabetes mellitus, hyperlipidemia, impaired glucose tolerance or the like.

discovery of the best compound 3h (HP590) among the investigated ones, a novel, highly potent, and orally bioavailable STAT3 inhibitor possessing lower nanomolar inhibitory activity toward p-Tyr705 and p-Ser727. Target validation revealed that HP590 selectivelytargets STAT3 to remarkably inhibit its canonical and noncanonical activation and corresponding biological functions, thereby resulting in the growth
