photo-isomerization behavior due to the azobenzene moiety in the side chain. Since the short spacer between polymer main-chain and side-chain, PDPA-azo could not form liquid-crystal phase despite the presence of azobenzenemesogen in the polymer structure. It was noted that the modification of the precursor polymer PDPA-PFP with primary amine-functionalized azobenzene converted the fluorescence behavior from aggregation-induced
backbone showed typical liquid-crystalline property and the mesophase was assigned to SmA phase. Their phase transition behaviors were further investigated by differential scanning calorimetric (DSC) measurements. The molecular packing modes were analyzed by using X-ray diffraction (XRD) measurement and theoretical simulation. These results revealed some details about the interactions between the polymer backbone
The development of PPARα/γ dual or PPARα/γ/δ pan-agonists could represent an efficacious approach for a simultaneous pharmacological intervention on carbohydrate and lipid metabolism. Two series of new phenyldiazenyl fibrate derivatives of GL479, a previously reported PPARα/γ dual agonist, were synthesized and tested. Compound 12a was identified as a PPAR pan-agonist with moderate and balanced activity
