  Studies towards the conception of new selective PPARβ/δ ligands

  摘要：

  In order to define new PPAR beta/delta ligands, SAR study on the selective PPAR beta/delta activator L-165,041 led to the identification of one key functional group for selective PPAR beta/delta activation. Further-more, taking advantage of SAR studies done elsewhere on the most selective PPAR beta/delta ligand GW501516, the conception of new ligands showing good affinity for PPAR beta/delta is reported. Finally, synthesis and biological evaluation of pyridine analogues have shown the benefical effect of the pyridine ring on the PPAR beta/ delta subtype selectivity.

  Protein tyrosine phosphatases (PTPs) are key regulators of metabolism and insulin signaling. As a negative regulator of insulin signaling, the low molecular weight protein tyrosine phosphatase (LMPTP) is a target for insulin resistance and related conditions. Described herein are compounds capable of modulating the level of activity of LMPTP, compositions, and methods of using these compounds and compositions.

  Lithiation of 3,5-dibromopyridine with LDA and subsequent reaction with electrophiles provided 4-alkyl-3,5-dibromopyridines 2 in high yield. 3-Bromo-4,5-dialkylpyridines 3 were synthesized by metal-halogen exchange of 2 with one equivalent n-BuLi and reaction with a second electrophile. Further metal-halogen exchange of 3 and reaction with a third electrophile provided 3,4,5-trisubstituted pyridines
