The present invention relates to compounds, pharmaceutical compositions and formulations that have a structure (I). The compounds comprise a heterocyclic ring where W, X, Y, and Z generally and independently are S, N or C with the proviso that at least 2 of these positions in the ring are other than carbon. A pyridine or a substituted pyridine A ring and a phenyl or a substituted phenyl B ring are covalently bonded to the heterocyclic ring. Further provided are methods for treating a metabolic disorder, cell proliferative disease, reducing body weight or increasing thermogenesis during weight loss with the compounds of structure as described or pharmaceutically acceptable salt or stereoisomer thereof or both.
